G-Sync gaming monitors don"t have to be crazy expensive anymore. That"s thanks to Nvidia"s support for many FreeSync gaming monitors when paired with an Nvidia graphics card, you can find both lower cost G-Sync Compatible gaming monitors as well as those equipped with an actual G-Sync module. G-Sync ensures your graphics card and monitor play together nicely to avoid the nasty screen tearing caused by misalignment between your GPU"s frame rate output and monitor"s refresh rate. G-Sync avoids the stuttering and input lag of V-Sync (not to mention limiting your frame rate to just 60fps).

So, if you"re in the market for a monitor with variable refresh rate (VRR) technology and you have an Nvidia graphics processor, it"s worth your while to see the affordable options available to you. We"ve picked out budget monitors that deliver either true G-Sync or confirmed compatibility through FreeSync – and click here to find them in the UK.

The LG UltraGear 32GP750-B brings G-Sync support and much more to love for around $350. You’re getting a big 31.5-inch display to see all the action, and the 1440p resolution helps keep it all crisp. LG is giving you an HDR boost with an IPS panel capable of dazzling at 400 nits of brightness and a solid contrast ratio. Colors should be vivid and accurate thanks to the monitor covering 99% of the sRGB color gamut and offering a 10-bit color depth.

Bright and colorful is good, but when you’re gaming, you want speed. This monitor goes above the typical 144Hz you find on most budget gaming monitors and hops up to 165Hz. Of course, your GPU and monitor won’t be able to keep up that high frame rate the entire time, so that’s where G-Sync compatibility steps in. This technology and its 1ms response time will keep the action butter-smooth and stutter-free for a more immersive gaming experience. All that performance comes alongside some extra utility thanks to a flexible stand.

If you"re looking to get G-Sync for the lowest price possible, the Asus TUF Gaming VG248Q1B delivers. Asus has an incredible lineup of budget-friendly G-sync compatible displays, a few of which are on this list, but this one will give you the best bang for your buck, coming in at around $170. You can get gaming at a fast refresh rate up to 165Hz at the high end or keep pace with your Nvidia graphics card all the way down to 48Hz. That’s a wide range of variable refresh rate support to ensure your gaming with the best possible visuals at all times. If you’ve got an AMD GPU in another rig, you also get support for FreeSync Premium. And your smooth gameplay is further enhanced by 0.5ms response time.

The monitor itself is a fairly straightforward ordeal, with no fancy HDR or extra-high peak brightness. You’re getting a 24-inch 1080p display toting basic features like flicker-free technology, low motion blur, and plenty of connectivity. Asus also packs in Shadow boost software, so you can spot enemies lurking in the darkness. The Asus TUF Gaming VG248Q1B is doing the job it set out to do, so don"t shy away from this monitor if you"re focus is fast gaming with no tearing over the sharpest possible image.

Speed is great for competitive gaming, but some games are just about the eye candy, and a 4K display can make them really shimmer. The Asus TUF Gaming VG289Q1A brings that 4K capability at an affordable price and backs it up with support for G-Sync. Since a steady framerate can be hard to maintain at 4K, having the G-Sync to back you up is crucial for clear visuals free of tearing or stutter.

The Asus TUF Gaming VG289Q1A boasts a bright, IPS display that supports a 10-bit color depth to give you over a billion colors to see. And, when we said this monitor came at an affordable price point, we meant it. You can grab it for just over $300.

You can get a lot of features all in one place if you know where to look. If you want a large display with a sharp resolution, a fast refresh rate, HDR support, and VRR compatiblity, then the Gigabyte G32QC is where you should look.

This monitor delivers a 32-inch display with a 1500R curvature to wrap it around your field of view and immerse you in your games. That display has DisplayHDR 400 certification, ensuring a strong picture quality that is just made better by its 1440p resolution, solid contrast ratio, and 165Hz refresh rate. G-Sync support will let you stay smooth even when you"re not displaying 165 frames per second.

Going with 1080p may not mean you"ll get the sharpest image, but you can get something those folks with 1440p and 4K monitors can"t yet: blistering speeds. And, at 1080p, you can even get it at a budget price. The Asus TUF Gaming VG258QM brings you a 280Hz refresh rate for just $300.

There are a few tradeoffs to hit that low price. For one thing, Asus used a TN panel. These don"t tend to have the best color or viewing angles, but when you"re gaming this hardcore, you should be looking at your monitor head-on anyway. Asus did manage to make the monitor fairly bright with a 400-nit peak brightness and DisplayHDR 400 certification, so you won"t miss out on enemies on account of a dim display. So, on a budget, this is a good pick for fast-paced esports.

Getting a G-Sync Compatible monitor instead of one that features a true G-Sync module may seem like cheating, but with everything that the NZXT Canvas 27Q has to offer, you’ll forget all about the fact that it"s not actual G-Sync. And if you also have another PC packing an AMD graphics card, you can take advantage of FreeSync Premium. Thanks to this impressive adaptive sync technology, this monitor delivers a tear-free gaming experience with a max refresh rate of 165Hz on the DisplayPort and USB-C connections. You also get an admirable 144Hz over the HDMI ports. Not bad for a monitor that’ll only set you back $320, and that’s just the start.

The NZXT Canvas 27Q totes a 1440p resolution on a 27-inch IPS panel. For such an affordable display, you still get a relatively high peak brightness at 300 nits that, along with its anti-glare coating, make it a great option for even your brighter spaces. However, this display truly shines when it comes to color performance, covering 99% of the sRGB color gamut. You get a wide range of vibrant colors, only you may find darker objects have a bit of haloing, and darker scenes have a gray glow. And annoyingly, you are going to have to purchase the stand separately for $40. If those slight flaws aren’t deal breakers, most should find this sturdy and attractive monitor to be a suitable option for their PC build.

Your budget doesn’t have to define your speeds with the Acer Nitro ED270. This 240Hz monitor is wildly affordable. It starts at $300, but we’ve seen it go as low as $219. That’s impressively low for any 27-inch gaming monitor, let alone one that can cruise at 240Hz. Aside from speed, the Acer Nitro ED270 isn’t entirely special. You won’t find a bright, HDR-capable panel to make AAA games really pop, and the monitor is achieving its speeds by using a VA panel rather than the IPS panels that tend to offer more attractive visuals.

But, at 1080p and 27 inches, the Nitro ED270 can provide sharp enough visuals that will provide a ton of extra clarity thanks to the high refresh rate. If you’re on a budget, your hardware might not always hit a full 240 fps, so that’s where the G-Sync compatibility of the monitor will come in to prevent stutter and tearing. Get ready for super-smooth gaming.

Screen tearing is just about the most upsetting thing that can happen to you while gaming. Previously the solution to this problem was to simply enable V-Sync in your game, which synced the output of the video card to your monitor"s maximum refresh rate, which was usually 60Hz.

Unfortunately, V-Sync introduces its own set of issues including increased input lag and capping the frame rate to a maximum of 60 fps—or 30 fps if you"re running below that.

In general, it works really well, but there are requirements. You need an Nvidia graphics card (minimum of a GTX 650 Ti Boost) and a G-Sync-enabled monitor connected by DisplayPort 1.2 or newer, and you need to turn it on in the Nvidia control panel software.

All G-Sync monitors have a proprietary G-Sync module in them that allows it to work, and with the right monitor and video card, you could get synced frame rates up to 240Hz.

G-Sync monitors tend to be around $100 to $200 more than the comparable FreeSync panels (which is attributed to the required module), so ‘cheap’ has a slightly different connotation here. That said, the best cheap G-Sync monitors let you experience a tear-free gaming experience without having to break the bank.

Better yet Nvidia has decreed that some Freesync monitors can be G-Sync Compatible, making them an amazingly affordable way to sidestep your way to a completely tear-free and smooth gaming experience with an Nvidia-powered system.

While Freesync monitors don"t include a dedicated G-Sync display module, Nvidia has tested over 400 displays and certified that at least 50 of them will definitely work with G-Sync. That said, our own testing has revealed there are even more compatible monitors out there.

The best G-Sync monitors make for a silky smooth gaming experience. This is because a G-Sync monitor will synchronize the frame rate to the output of your graphics card. The end result is a tear-free experience. This is just as great for high frame rates as it is for sub-60fps too, so you"re covered for whatever games you love to play.

But what is G-Sync tech? For the uninitiated, G-Sync is Nvidia"s name for its frame synchronization technology. It makes use of dedicated silicon in the monitor so it can match your GPU"s output to your gaming monitor"s refresh rate, for the smoothest gaming experience. It removes a whole load of guesswork in getting the display settings right, especially if you have an older GPU. The catch is that the tech only works with Nvidia GPUs.

G-Sync Ready or G-Sync Compatible monitors can be found, too. They"re often cheaper, but the monitors themselves don"t have dedicated G-Sync silicon inside them. You can still use G-Sync, but for best results, you want a screen that"s certified by Nvidia(opens in new tab).

Here"s where things might get a little complicated: G-Sync features do work with AMD"s adaptive FreeSync tech monitors, but not the other way around. If you have an AMD graphics card, you"ll for sure want to check out the best FreeSync monitors(opens in new tab) along with checking our overall best gaming monitors(opens in new tab) for any budget.

Brand new gaming monitor technology comes at a premium, and the Asus ROG Swift PH32UQX proves that point. As the world"s first Mini-LED gaming monitor, it sets a precedent for both performance and price, delivering extremely impressive specs for an extreme price tag.

The PG32UQX is easily one of the best panels I"ve used to date. The colors are punchy yet accurate and that insane brightness earns the PG32UQX the auspicious DisplayHDR 1400 certification. However, since these are LED zones and not self-lit pixels like an OLED, you won"t get those insane blacks for infinite contrast.

Mini-LED monitors do offer full-array local dimming (FALD) for precise backlight control, though. What that means for the picture we see is extreme contrast from impressive blacks to extremely bright DisplayHDR 1400 spec.If you want to brag with the best G-Sync gaming monitor around, this is the way to do it.

Beyond brightness, you can also expect color range to boast about. The colors burst with life and the dark hides ominous foes for you to slay in your quest for the newest loot.

Of course, at 4K you"ll need the equivalent of one of the best gaming PCs(opens in new tab) to get 144fps. I did get Doom Eternal to cross the 144Hz barrier in 4K HDR using an RTX 3080 and boy was it marvelous.

That rapid 144Hz refresh rate is accompanied by HDMI 2.0 and DisplayPort 1.4 ports, along with two USB 3.1 ports join the action, with a further USB 2.0 sitting on the top of the monitor to connect your webcam.

As for its G-Sync credentials, the ROG Swift delivers G-Sync Ultimate, which is everything a dedicated G-Sync chip can offer in terms of silky smooth performance and support for HDR. So if you want to brag with the best G-Sync gaming monitor around, this is the way to do it. However, scroll on for some more realistic recommendations in terms of price.

OLED has truly arrived on PC, and in ultrawide format no less. Alienware"s 34 QD-OLED is one of very few gaming monitors to receive such a stellar score from us, and it"s no surprise. Dell has nailed the OLED panel in this screen and it"s absolutely gorgeous for PC gaming. Although this monitor isn’t perfect, it is dramatically better than any LCD-based monitor by several gaming-critical metrics. And it’s a genuine thrill to use.

What that 34-inch, 21:9 panel can deliver in either of its HDR modes—HDR 400 True Black or HDR Peak 1000—is nothing short of exceptional. The 3440 x 1440 native resolution image it produces across that gentle 1800R curve is punchy and vibrant. With 99.3% coverage of the demanding DCI-P3 colour space, and fully 1,000 nits brightness, it makes a good go, though that brightness level can only be achieved on a small portion of the panel.

Still, there’s so much depth, saturation and clarity to the in-game image thanks to that per-pixel lighting, but this OLED screen needs to be in HDR mode to do its thing. And that applies to SDR content, too. HDR Peak 1000 mode enables that maximum 1,000 nit performance in small areas of the panel but actually looks less vibrant and punchy most of the time.The Alienware 34 QD-OLED"s response time is absurdly quick at 0.1ms.

HDR 400 True Black mode generally gives the best results, after you jump into the Windows Display Settings menu and crank the SDR brightness up, it looks much more zingy.

Burn-in is the great fear and that leads to a few quirks. For starters, you’ll occasionally notice the entire image shifting by a pixel or two. The panel is actually overprovisioned with pixels by about 20 in both axes, providing plenty of leeway. It’s a little like the overprovisioning of memory cells in an SSD and it allows Alienware to prevent static elements from “burning” into the display over time.

Latency is also traditionally a weak point for OLED, and while we didn’t sense any subjective issue with this 175Hz monitor, there’s little doubt that if your gaming fun and success hinges on having the lowest possible latency, there are faster screens available. You can only achieve the full 175Hz with the single DisplayPort input, too.

The Alienware 34 QD-OLED"s response time is absurdly quick at 0.1ms, and it cruised through our monitor testing suite. You really notice that speed in-game, too.

There"s no HDMI 2.1 on this panel, however. So it"s probably not the best fit for console gaming as a result. But this is PC Gamer, and if you"re going to hook your PC up to a high-end gaming monitor, we recommend it be this one.

4K gaming is a premium endeavor. You need a colossal amount of rendering power to hit decent frame rates at such a high resolution. But if you"re rocking a top-shelf graphics card, like an RTX 3080(opens in new tab), RTX 3090(opens in new tab), or RX 6800 XT(opens in new tab) then this dream can be a reality, at last. While the LG 27GN950-B is a fantastic gaming panel, it"s also infuriatingly flawed.

The LG UltraGear is the first 4K, Nano IPS, gaming monitor with 1ms response times, that"ll properly show off your superpowered GPU. Coming in with Nvidia G-Sync and AMD’s FreeSync adaptive refresh compatibility, this slick slim-bezel design even offers LG’s Sphere Lighting 2.0 RGB visual theatrics.

And combined with the crazy-sharp detail that comes with the 4K pixel grid, that buttery smooth 144Hz is pretty special.The color fidelity of the NanoIPS panel is outstanding.

While it does suffer with a little characteristic IPS glow. It appears mostly at the screen extremities when you’re spying darker game scenes, but isn"t an issue most of the time. The HDR is a little disappointing as, frankly, 16 edge-lit local dimming zones do not a true HDR panel make.

What is most impressive, however, is the Nano IPS tech that offers a wider color gamut and stellar viewing angles. And the color fidelity of the NanoIPS panel is outstanding.

The LG UltraGear 27GN950-B bags you a terrific panel with exquisite IPS image quality. Despite the lesser HDR capabilities, it also nets beautiful colors and contrast for your games too. G-Sync offers stable pictures and smoothness, and the speedy refresh rate and response times back this up too.

The MSI Optix MPG321UR is kitted out for high-speed 4K gaming, and it absolutely delivers. Despite the price point this monitor doesn’t have a physical G-Sync chip, it is officially certified and has been tested by Nvidia to hit the necessary standards for G-Sync compatibility. It does also offer FreeSync Premium Pro certification, as well as DCI-P3 RGB color space and sRGB.

That makes this a versatile piece of kit, and that 3840 x 2160 resolution is enough to prevent any pixelation across this generous, 32-inch screen. The 16:9 panel doesn"t curve, but does offer a professional-level, sub 1ms grey-to-grey (GTG) response rate.

Sadly, there"s been no effort to build in any custom variable overdrive features, so you’ll have to expect you"ll get artifacts on fast moving objects.

Still, the MSI Optix MPG321UR does come with a 600nit peak brightness, and Vesa HDR 600 certification, alongside 97% DCI-P3 colour reproduction capabilities. All this goes toward an amazingly vibrant screen that"s almost accurate enough to be used for professional colour grading purposes.

The Optix is one of MSI"s more recent flagship models, so you know you"re getting serious quality and performance. Its panel looks gorgeous, even at high speeds, managing a 1ms GTG response time.

Though MSI"s Optix is missing a physical G-Sync chip, it"ll still run nicely with any modern Nvidia GPU, or AMD card if you happen to have one of those lying around.

The Xeneon is Corsair"s attempt at breaking into the gaming monitor market. To do that, the company has opted for 32 inches of IPS panel at 1440p resolution. Once again we"re looking at a FreeSync Premium monitor that has been certified to work with GeForce cards by Nvidia.

It pretty much nails the sweetspot for real-world gaming, what with 4K generating such immense levels of GPU load and ultrawide monitors coming with their own set of limitations.

The 2,560 by 1,440 pixel native resolution combined with the 32-inch 16:9 aspect panel proportions translate into sub-100DPI pixel density. That’s not necessarily a major problem in-game. But it does make for chunky pixels in a broader computing context.It‘s punchy, vibrant, and well-calibrated.

Here, you"re looking at a swanky cast aluminum stand, which adjusts for height, tilt, and swivel, and is a definite cut above the norm for build quality. The OSD menu UI is clearer and more logical than many, too, and those unusually high levels of polish and refinement extend yet further.

That sub-3ms response, combined with a 165Hz refresh, means the thing isn"t a slouch when it comes to gaming capability, though there are certainly more impressive gaming monitors out there.

The two HDMI 2.0 sockets are limited to 144Hz, and the DisplayPort 1.4 interface is predictable enough. But the USB Type-C with power delivery for a single cable connection with charging to a laptop is a nice extra. Or, at least, it would be if the charging power wasn’t limited to a mere 15W, which is barely enough for something like a MacBook Air, let alone a gaming laptop.

The core image quality is certainly good, though. It‘s punchy, vibrant, and well-calibrated. And while it"s quite pricey for a 1440p model, it delivers all it sets out to with aplomb. On the whole, the Corsair Xeneon 32QHD165 doesn’t truly excel at anything, but it"s still a worthy consideration in 2022.

Housing Nvidia’s tech alongside a 4K resolution and HDR tech means that this is an absolute beast of a monitor that will give you the best of, well, everything. And by everything, we mean everything.

The XB273K’s gaming pedigree is obvious the second you unbox it: it is a 27-inch, G-Sync compatible, IPS screen, that boasts a 4ms gray-to-gray response rate, and a 144Hz refresh rate. While that may not sound like a heck of a lot compared to some of today"s monitors, it also means you can bag it for a little less.

Assassin’s Creed Odyssey looked glorious. This monitor gave up an incredibly vivid showing, and has the crispest of image qualities to boot; no blurred or smudged edges to see and each feature looks almost perfectly defined and graphically identified.The contrasts are particularly strong with any colors punching through the greys and blacks.

Particular highlights are the way water effects, lighting, reflections and sheens are presented, but there is equal enjoyment to be had from landscape features, the people, and urban elements. All further benefiting from a widespread excellence in color, contrast, shades (and shadows), and tones.

The contrasts are particularly strong with any colors punching through the greys and blacks. However, the smaller details here are equally good, down to clothing detail, skin tone and complexion, and facial expressions once again. There is an immersion-heightening quality to the blacks and grays of the Metro and those games certainly don’t feel five years old on the XB273K.

The buttons to access the menu are easy enough to use, and the main stick makes it particularly simple to navigate. And the ports you have available increase your ability to either plug and go or adapt to your machines’ needs: an HDMI; DisplayPort and five USB 3.0 ports are at your service.

The Predator XB273K is one for those who want everything now and want to future-proof themselves in the years ahead. It might not have the same HDR heights that its predecessor, the X27, had, but it offers everything else for a much-reduced price tag. Therefore, the value it provides is incredible, even if it is still a rather sizeable investment.

The best just got a whole lot better. That’s surely a foregone conclusion for the new Samsung Odyssey Neo G9. After all, the original Odyssey G9 was already Samsung’s tip-top gaming monitor. Now it’s been given the one upgrade it really needed. Yup, the Neo G9 is packing a mini-LED backlight.

Out of the box, it looks identical to the old G9. Deep inside, however, the original G9’s single most obvious shortcoming has been addressed. And then some. The Neo G9 still has a fantastic VA panel. But its new backlight doesn’t just have full-array rather than edge-lit dimming.

It packs a cutting-edge mini-LED tech with no fewer than 2,048 zones. This thing is several orders of magnitude more sophisticated than before. As if that wasn’t enough, the Neo G9’s peak brightness has doubled to a retina-wrecking 2,000 nits. What a beast.

The problem with any backlight-based rather than per-pixel local dimming technology is that compromises have to be made. Put another way, an algorithm has to decide how bright any given zone should be based on the image data. The results are never going to be perfect.

Visible halos around small, bright objects are the sort of issue you expect from full-array dimming. But the Neo G9 has its own, surprisingly crude, backlight-induced image quality issues. Admittedly, they’re most visible on the Windows desktop rather than in-game or watching video.Graphics-heavy titles such as Cyberpunk 2077 or Witcher III are what the G9 does best.

If you position a bright white window next to an all-black window, the adjacent edge of the former visibly dims. Or let’s say you move a small, bright object over a dark background. The same thing happens. The small, bright object dims. Even uglier, if something like a bright dialogue box pops up across the divide between light and dark elements, the result is a gradient of brightness across the box.

All this applies to both SDR and HDR modes and, on the Windows desktop, it’s all rather messy and distracting. Sure, this monitor isn’t designed for serious content creation or office work. But at this price point, it’s surely a serious flaw.

Still, that 1000R curve, huge 49-inch proportions, and relatively high resolution combine to deliver an experience that few, if any, screens can match. Graphics-heavy titles such as Cyberpunk 2077 or Witcher III are what the G9 does best. In that context, the Samsung Odyssey Neo G9 delivers arguably the best visual experience on the PC today.

In practice, the Neo G9’s mini-LED creates as many problems as it solves. We also can’t help but observe that, at this price point, you have so many options. The most obvious alternative, perhaps, is a large-format 120Hz OLED TV with HDMI 2.1 connectivity.

G-Sync gaming monitor FAQWhat is the difference in G-Sync and G-Sync Compatible?G-Sync and G-Sync Ultimate monitors come with a bespoke G-Sync processor, which enables a full variable refresh rate range and variable overdrive. G-Sync Compatible monitors don"t come with this chip, and that means they may have a more restricted variable refresh rate range.

Fundamentally, though, all G-Sync capable monitors offer a smoother gaming experience than those without any frame-syncing tech.Should I go for a FreeSync or G-Sync monitor?In general, FreeSync monitors will be cheaper. It used to be the case that they would only work in combination with an AMD GPU. The same went for G-Sync monitors and Nvidia GPUs. Nowadays, though, it is possible to find G-Sync compatible FreeSync monitors(opens in new tab) if you"re intent on spending less.Should I go for an IPS, TN or VA panel?We would always recommend an IPS panel over TN(opens in new tab). The clarity of image, viewing angle, and color reproduction are far superior to the cheaper technology, but you"ll often find a faster TN for cheaper. The other alternative, less expensive than IPS and better than TN, is VA tech. The colors aren"t quite so hot, but the contrast performance is impressive.

The speed at which the screen refreshes. For example, 144Hz means the display refreshes 144 times a second. The higher the number, the smoother the screen will appear when you play games.

Graphics tech synchronizes a game"s framerate with your monitor"s refresh rate to help prevent screen tearing by syncing your GPU frame rate to the display"s maximum refresh rate. Turn V-Sync on in your games for a smoother experience, but you"ll lose information, so turn it off for fast-paced shooters (and live with the tearing). Useful if you have an older model display that can"t keep up with a new GPU.

G-SyncNvidia"s frame synching tech that works with Nvidia GPUs. It basically allows the monitor to sync up with the GPU. It does by showing a new frame as soon as the GPU has one ready.

AMD"s take on frame synching uses a similar technique as G-Sync, with the biggest difference being that it uses DisplayPort"s Adaptive-Sync technology which doesn"t cost monitor manufacturers anything.

When movement on your display leaves behind a trail of pixels when watching a movie or playing a game, this is often a result of a monitor having slow response times.

The amount of time it takes a pixel to transition to a new color and back. Often referenced as G2G or Grey-to-Grey. Slow response times can lead to ghosting. A suitable range for a gaming monitor is between 1-4 milliseconds.

TN PanelsTwisted-nematic is the most common (and cheapest) gaming panel. TN panels tend to have poorer viewing angles and color reproduction but have higher refresh rates and response times.

IPSIn-plane switching, panels offer the best contrast and color despite having weaker blacks. IPS panels tend to be more expensive and have higher response times.

VAVertical Alignment panels provide good viewing angles and have better contrast than even IPS but are still slower than TN panels. They are often a compromise between a TN and IPS panel.

HDRHigh Dynamic Range. HDR provides a wider color range than normal SDR panels and offers increased brightness. The result is more vivid colors, deeper blacks, and a brighter picture.

ResolutionThe number of pixels that make up a monitor"s display, measured by height and width. For example: 1920 x 1080 (aka 1080p), 2560 x 1440 (2K), and 3840 x 2160 (4K).Round up of today"s best deals

When buying a gaming monitor, it’s important to compare G-Sync vs FreeSync. Both technologies improve monitor performance by matching the performance of the screen with the graphics card. And there are clear advantages and disadvantages of each: G-Sync offers premium performance at a higher price while FreeSync is prone to certain screen artifacts like ghosting.

So G-Sync versus FreeSync? Ultimately, it’s up to you to decide which is the best for you (with the help of our guide below). Or you can learn more about ViewSonic’s professional gaming monitors here.

In the past, monitor manufacturers relied on the V-Sync standard to ensure consumers and business professionals could use their displays without issues when connected to high-performance computers. As technology became faster, however, new standards were developed — the two main ones being G-Sync and Freesync.

V-Sync, short for vertical synchronization, is a display technology that was originally designed to help monitor manufacturers prevent screen tearing. This occurs when two different “screens” crash into each other because the monitor’s refresh rate can’t keep pace with the data being sent from the graphics card. The distortion is easy to spot as it causes a cut or misalignment to appear in the image.

This often comes in handy in gaming. For example, GamingScan reports that the average computer game operates at 60 FPS. Many high-end games operate at 120 FPS or greater, which requires the monitor to have a refresh rate of 120Hz to 165Hz. If the game is run on a monitor with a refresh rate that’s less than 120Hz, performance issues arise.

V-Sync eliminates these issues by imposing a strict cap on the frames per second (FPS) reached by an application. In essence, graphics cards could recognize the refresh rates of the monitor(s) used by a device and then adjust image processing speeds based on that information.

Although V-Sync technology is commonly used when users are playing modern video games, it also works well with legacy games. The reason for this is that V-Sync slows down the frame rate output from the graphics cards to match the legacy standards.

Despite its effectiveness at eliminating screen tearing, it often causes issues such as screen “stuttering” and input lag. The former is a scenario where the time between frames varies noticeably, leading to choppiness in image appearances.

V-Sync only is useful when the graphics card outputs video at a high FPS rate, and the display only supports a 60Hz refresh rate (which is common in legacy equipment and non-gaming displays). V-Sync enables the display to limit the output of the graphics card, to ensure both devices are operating in sync.

Although the technology works well with low-end devices, V-Sync degrades the performance of high-end graphics cards. That’s the reason display manufacturers have begun releasing gaming monitors with refresh rates of 144Hz, 165Hz, and even 240Hz.

While V-Sync worked well with legacy monitors, it often prevents modern graphics cards from operating at peak performance. For example, gaming monitors often have a refresh rate of at least 100Hz. If the graphics card outputs content at low speeds (e.g. 60Hz), V-Sync would prevent the graphics card from operating at peak performance.

Since the creation of V-Sync, other technologies such as G-Sync and FreeSync have emerged to not only fix display performance issues, but also to enhance image elements such as screen resolution, image colors, or brightness levels.

Released to the public in 2013, G-Sync is a technology developed by NVIDIA that synchronizes a user’s display to a device’s graphics card output, leading to smoother performance, especially with gaming. G-Sync has gained popularity in the electronics space because monitor refresh rates are always better than the GPU’s ability to output data. This results in significant performance issues.

For example, if a graphics card is pushing 50 frames per second (FPS), the display would then switch its refresh rate to 50 Hz. If the FPS count decreases to 40, then the display adjusts to 40 Hz. The typical effective range of G-Sync technology is 30 Hz up to the maximum refresh rate of the display.

The most notable benefit of G-Sync technology is the elimination of screen tearing and other common display issues associated with V-Sync equipment. G-Sync equipment does this by manipulating the monitor’s vertical blanking interval (VBI).

VBI represents the interval between the time when a monitor finishes drawing a current frame and moves onto the next one. When G-Sync is enabled, the graphics card recognizes the gap, and holds off on sending more information, therefore preventing frame issues.

To keep pace with changes in technology, NVIDIA developed a newer version of G-Sync, called G-Sync Ultimate. This new standard is a more advanced version of G-Sync. The core features that set it apart from G-Sync equipment are the built-in R3 module, high dynamic range (HDR) support, and the ability to display 4K quality images at 144Hz.

Although G-Sync delivers exceptional performance across the board, its primary disadvantage is the price. To take full advantage of native G-Sync technologies, users need to purchase a G-Sync-equipped monitor and graphics card. This two-part equipment requirement limited the number of G-Sync devices consumers could choose from It’s also worth noting that these monitors require the graphics card to support DisplayPort connectivity.

While native G-Sync equipment will likely carry a premium, for the time being, budget-conscious businesses and consumers still can use G-Sync Compatible equipment for an upgraded viewing experience.

Released in 2015, FreeSync is a standard developed by AMD that, similar to G-Sync, is an adaptive synchronization technology for liquid-crystal displays. It’s intended to reduce screen tearing and stuttering triggered by the monitor not being in sync with the content frame rate.

Since this technology uses the Adaptive Sync standard built into the DisplayPort 1.2a standard, any monitor equipped with this input can be compatible with FreeSync technology. With that in mind, FreeSync is not compatible with legacy connections such as VGA and DVI.

The “free” in FreeSync comes from the standard being open, meaning other manufacturers are able to incorporate it into their equipment without paying royalties to AMD. This means many FreeSync devices on the market cost less than similar G-Sync-equipped devices.

As FreeSync is a standard developed by AMD, most of their modern graphics processing units support the technology. A variety of other electronics manufacturers also support the technology, and with the right knowledge, you can even get FreeSync to work on NVIDIA equipment.

Although FreeSync is a significant improvement over the V-Sync standard, it isn’t a perfect technology. The most notable drawback of FreeSync is ghosting. This is when an object leaves behind a bit of its previous image position, causing a shadow-like image to appear.

The primary cause of ghosting in FreeSync devices is imprecise power management. If enough power isn’t applied to the pixels, images show gaps due to slow movement. On the other hand when too much power is applied, then ghosting occurs.

To overcome those limitations, in 2017 AMD released an enhanced version of FreeSync known as FreeSync 2 HDR. Monitors that meet this standard are required to have HDR support; low framerate compensation capabilities (LFC); and the ability to toggle between standard definition range (SDR) and high dynamic range (HDR) support.

A key difference between FreeSync and FreeSync 2 devices is that with the latter technology, if the frame rate falls below the supported range of the monitor, low framerate compensation (LFC) is automatically enabled to prevent stuttering and tearing.

As FreeSync is an open standard – and has been that way since day one – people shopping for FreeSync monitors have a wider selection than those looking for native G-Sync displays.

If performance and image quality are your top priority when choosing a monitor, then G-Sync and FreeSync equipment come in a variety of offerings to fit virtually any need. The primary difference between the two standards is levels of input lag or tearing.

If you want low input lag and don’t mind tearing, then the FreeSync standard is a good fit for you. On the other hand, if you’re looking for smooth motions without tearing, and are okay with minor input lag, then G-Sync equipped monitors are a better choice.

For the average individual or business professional, G-Sync and FreeSync both deliver exceptional quality. If cost isn’t a concern and you absolutely need top of the line graphics support, then G-Sync is the overall winner.

Gaming monitor options keep growing with new brands, features, and ever-growing capabilities. It"s an exciting time to be a PC gamer, but that also means that selecting the best gaming monitor for your rig is growing more complicated every day. The selection can be overwhelming, from screen-smoothing technologies (Nvidia G-Sync and AMD FreeSync) to ultra-fast refresh rates that can reach a mind-blowing 360 Hz.

For pixel addicts, there are dense 4K screens that are just as hard on your wallet as they are on the latest graphics cards. Thankfully, we have plenty of excellent picks for you to upgrade your tired old monitor.

Why you can trust Tom"s HardwareOur expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

When seeking the best gaming monitor for your rig, there are different panel types vying for your eyeballs — IPS(opens in new tab), TN(opens in new tab), VA(opens in new tab) and even OLED(opens in new tab)— each with its own pros and cons. You can"t forget about screen size and aspect ratio, which affect your views, desk space and, again, bank account. And we haven"t even discussed bonuses, like speakers, RGB or port selection. How"s a gamer to choose with all of these options?

For a deep dive into how to pick the best monitor--gaming or otherwise--check out our PC Monitor Buying Guide(opens in new tab). Below is a list of the best gaming monitors out there right now, based on our own tests.

G-Sync or FreeSync? G-Sync only works with PCs with Nvidia graphics cards, while FreeSync only works with systems using AMD ones. You can technicallyrun G-Sync on a FreeSync-only monitor, but performance isn"t guaranteed. FreeSync monitors tend to be cheaper, but performance is comparable. For a detailed comparison of the two technologies’ performance, see our Nvidia G-Sync vs. AMD FreeSync comparison(opens in new tab) article.

For image quality, TN < IPS < VA. Generally speaking. Typically, TN monitors are the fastest but cheapest, due to weaker viewing angles. IPS displays have slightly slower response times but better color than VA monitors. The best gaming monitors for contrast are VA, but VA also has slower response times.

Refresh rates: bigger is better. This number explains the number of times your monitor updates with new information per second — stated in hertz (Hz) — and, therefore, how many frames per second (fps) the monitor can display. Bigger numbers mean smoother images. Refresh rate is especially important for gamers, so you’ll want to shoot for a monitor with at least 75 Hz (most gaming monitors offer at least 144 Hz), combined with the lowest response time you can find.

Resolution: Full HD, QHD, 4K. The most popular screen resolutions for gaming monitors are Full HD (1920 x 1080), QHD (2560 x 1440) and 4K (3840 x 2160). The more pixels a screen has, the sharper its image should look. So a 4K monitor will be able to show a more crisp image and more detail than a lower resolution Full HD monitor. Generally speaking, the lowest resolution monitors push the fastest refresh rates, reaching upwards of 360Hz. Because they have to push many more pixels, 4K monitors usually top out at a 144Hz refresh rate.

The Dell S3222DGM is just a great, all-around pick as the top gaming monitor thanks to its excellent image quality, plentiful features and typical solid build quality. At the heart of this display is a 2560 x 1440, curved VA panel that supports both AMD FreeSync and Nvidia G-Sync at up to 165 Hz.

The S3222DGM"s delivers an enviable contrast ratio thanks to its 1800R curved VA panel. While the IPS competition often struggles to break much past 1,000:1, the S3222DGM"s VA panels shot to 4209:1 in our tests. The display also reproduced 122 percent of the sRGB color gamut and 85 percent of the DCI-P3 gamut on our tests along with an incredibly accurate gamut error rate of 2.07dE.

Desktop-class OLEDs used to be a rarity in the gaming monitor segment, but over the years, prices have come down, and more entries have entered the fray. The latest comes to us from Alienware, and it’s the jaw-dropping AW3423DFW.

This is a 34-inch ultra-wide monitor with a 1800R curve and a resolution of 3440 x 1440. However, the most important spec is its use of a Quantum Dot OLED (QD-OLED) panel, which offers an extremely wide color gamut and the blackest blacks you’ll find in a gaming monitor.

The QD-OLED “heart” of the AW3423DFW gives it unmatched contrast and excellent color saturation and we felt no need to calibrate the panel further out of the box. Throw in premium build quality – as we expect from Alienware – and top-notch video processing and the AW3423DFW hit all the high notes without any demerits worth mentioning for enthusiast gamers.

With a price tag of around $250, the Monoprice Dark Matter 42770 is an easy to recommend 1080p gaming monitor with a wide color gamut, excellent contrast ratio for an IPS display and solid build quality. At this price, you"re getting a relatively barebones monitor, but Monoprice spent its time throwing in the features that matter most to gamers on a budget.

The Dark Matter 42770 offers a 1ms GTG response time and tops out with a 144 Hz refresh rate. Another feather in its cap is that the monitor supports both AMD FreeSync and NVIDIA G-Sync Adaptive-Sync technologies.

Although the monitor doesn"t support HDR, its native dynamic range is excellent, and it features a wide color gamut and excellent gamma tracking. Its deep blacks are welcome here given that this is an IPS panel, with its color and contrast on part with monitors that costs hundreds of dollars more.

The Gigabyte G27F2 represents a revamp of theG27F we first reviewed in late 2020. While the original monitor was highlighted by a 144Hz panel, the new G27F2 revision ups that figure to 170Hz. While that might not be as fast as more high-end Full HD gaming monitors, we have to remember that the G27F2 has a bargain basement price of just over $200.

However, that low price doesn"t mean that Gigabyte skimped on quality. You"ll still find low response times and input lag compared to others in this segment. In addition, the build quality throughout is excellent, as is color accuracy and contrast (which is somewhat of a revelation given that the G27F2 uses an IPS panel instead of VA).

The Dell G3223Q is a stellar entry in the 4K gaming monitor segment, offering a 32-inch panel size, low total input lag (measured at just 30ms) and an excellent balance between response and motion resolution. As you might expect for a 4K gaming monitor, we have a 144Hz refresh rate with support for both AMD FreeSync and Nvidia G-Sync Adaptive Sync technologies.

Not only does the Dell G3223Q nail the basics, but it also offers a bright and colorful picture. And color accuracy straight out of the box is top notch in both DCI-P3 and sRGB color gamuts. With DisplayHDR 600 support, accuracy and color reproduction were also well represented in HDR mode.

The HyperX Armada 27 is one of those standout monitors that offers the whole package. This is a 27-inch QHD display with a 2560 x 1440 resolution, 165Hz refresh rate HDR and premium built quality that we expect from HyperX.

One thing that makes the Armada 27 stand out (along with its smaller Armada 25 sibling) is the inclusion of a gaming mount for attaching the monitor to your desk instead of a traditional stand. This gives customers greater flexibility in positioning the Armada 27 for height, swivel and tilt.

If you like your games to look extra colorful, the MSI Optix MAG274QRF-QD is the best gaming monitor for your rig. This monitor posted the widest color gamut we’ve ever recorded: 112.19% of DCI-P3 after our recommended calibration. 90% of DCI-P3 would be impressive, so this is one color-saturated screen.

Contrast is also strong for an IPS panel, hitting 1,129.1:1 after our calibration. And for those concerned about speed, this 165 Hz screen kept up with the 170 Hz Gigabyte M27Q in our testing

Color purists, however, will lament the lack of an sRGB mode, considering the MAG274QRF-QD’s sRGB coverage is at 166.33%. Its backlight strobe for fighting motion blur is also a disappointment. You can’t use Adaptive-Sync with it, the brightness goes down by about 50% and it created ghosting that resulted in a parallax effect with fast motion. In addition, this is yet another gaming monitor to offer HDR but without any noticeable image boost over SDR.

The Viotek GNV34DBE is a well-performing and affordable curved gaming monitor. Its 1500R curve proved to add an immersive touch while gaming, helping to fill our peripheral vision. Despite its tight curve, we still found the GNV34DBE fit for working. There was no distortion, and we enjoyed having multiple windows open for boosted productivity.

But it’s not just about the GNV34DBE’s curve. You also get a 144 Hz refresh rate and response times and input lag that kept up with 144 Hz rivals during our testing. On the battlefield, we realized the high pixel density of a 1440p screen and smooth gaming without any screen tearing, thanks to FreeSync. Color and contrast were competitive with pricier gaming displays too.

Gigabyte’s Aorus CV27Q is the best 1440p gaming monitor when it comes to high-speed gaming performance. With its impressive specs, it shined in our input lag and response time tests when pitted against 144 Hz rivals. Sure, you could get slightly better performance from the 1080p version, the Aorus CV27F, but then you wouldn’t be getting that sharper QHD resolution or higher pixel density (109ppi).

With a VA panel offering 3,000:1 contrast, image quality is no joke either. The CV27Q has a low black level that made image depth look great, particularly with HDR titles. But as far as HDR goes, this monitor only goes up to 400 nits brightness; we prefer HDR displays that hit at least 600 nits.

If you have extra room in your budget and want to squeeze out that additional drop of performance from your 1440p screen, the Asus ROG Strix XG27AQ may be the best gaming monitor for you. This screen is ready to compete with the speediest of screens, competing well against other 165-170 Hz screens in our response time test and falling just 1-3ms behind in our input lag test.

Out of the box, we recorded solid IPS contrast (1,158.4:1). Of course, you’ll want to calibrate to get rid of some visible grayscale tracking errors, but our recommended settings can help you there. This is also an excellent HDR monitor, thanks to a dynamic contrast feature that bumps contrast up to a whopping 22,506.9:1.

Not only does it have the sharper resolution of your dreams, but it’s one of the rare monitors to allow you to run blur reduction alongside side screen tear-fighting Adaptive-Sync.

The Razer Raptor 27 is the best gaming monitor for 144 Hz refresh rates. It"ll make any gamer you know jealous with premium touches, like an RGB stand, flat green cables for cable management and drool-worthy build quality. Plus, HDR delivery is some of the best we’ve seen in an edge-lit panel yet.

Despite its 144Hz refresh rate, the Raptor 27 was able to stay competitive with 165Hz monitors in our benchmarking. There wasn"t significant motion blur, but finicky, pro-level players will have to choose between dealing with it or activating the backlight strobe, which limits you to 120Hz, reduces brightness by 40% and grays out FreeSync and G-Sync Compatibility.

For speed demons, a 240 Hz monitor hits the spot. Up until recently, that level of speed required two things: settling for 1080p resolution and a TN panel. But the Asus" 27-inch ROG Swift PG279QM is the best gaming monitor in this class. It manages that speed with a color-accurate IPS panel. Not only does it deliver a huge color gamut, but it also has excellent video processing and premium build quality.

The 32-inch Samsung Odyssey G7 is in a class all its own. It’s one of Samsung’s 1000R screens, meaning it’s one of the curviest gaming monitors you can find on the market. If you’re a fan of the immersive feel of a curved monitor, the 32” Odyssey G7 will elevate this experience even higher.

At 32 inches, the Odyssey G7’s amazing 1000R curve drew us in, whether we were playing games or doing work. With this curvature, we could view productivity apps without any image distortion, and when gaming our vision was filled with action. The 32-inch, 16:9 build offers ample height for productivity and, coupled with 1440p resolution, hits a sweet spot for gaming.

In terms of image quality, the 32-inch Odyssey G7 proved accurate before we even calibrated it while boasting a 2,121:1 contrast ratio, according to our testing.

The 27-inch gaming monitor competition is crowded, but the Viotek GFI27DBXA stands out with an incredibly colorful image that’s also bright and sharp. The 1440p panel covers 101% of the DCI-P3 color space, according to our testing. Contrast, meanwhile, proved comparable to your typical IPS panel, but the dynamic contrast feature helped when gaming. Combined with the wide color coverage, the image impressed during gaming.

Speed-wise, the GFI27DBXA is ready to play. In our benchmarks, it showed a competitive 6ms response time. With a 180 Hz refresh rate, it fell behind 165 and 170 Hz screens from more premium brands but only by 2-6ms. Plus, its overdrive is one of the best we’ve seen, ensuring zero perceivable delays for mainstream players. Plus, the monitor feels strong and reliable, despite its lower price.

The Dell S2422HG might be small in stature at just 23.6 inches across, but it packs quite a punch at a very attractive price point. Not everyone has the cash to drop $400 or $500 on a gaming monitor, so it"s nice to see Dell providing a value-conscious entry here.

The S2422HG has a 1920 x 1080 resolution and a relatively fast refresh rate at 165 MHz. Dell uses a VA panel here, so you get excellent contrast at 3,000:1 (we measured better at 3,261.8:1) and a factory-rated brightness of 350 nits (although we only measured 324 nits). We also commend Dell for including both AMD FreeSync and Nvidia G-Sync compatibility in this budget-oriented monitor.

Video processing for the S2422HG was good in our testing, and the low input lag was appreciated. However, we did have to knock the motor for its lack of sRGB mode, no integrated speakers, and a lack of USB hub functionality.

The Samsung 49-Inch Odyssey G9 is one of the most extreme monitors on this page. Not only is it a massive 49 inches diagonally, but it also carries a 1000R curve, the most dramatic curve offered on a gaming monitor today. From a 2-3-feet distance, this panel will fill your view. It’s like having two 27-inch, 1440p monitors in one. You"ll need nearly 4 feet of desk width and 17 inches of depth to accommodate it, but if you do, you’ll enjoy a wraparound gaming environment without image distortion. Are you looking for a smaller ultrawide? The Acer Predator X38is also excellent.

Testing of the 49-Inch Odyssey G9 revealed excellent contrast (2,152.9:1 after calibration), which climbed to 58,881.7:1 when it came to HDR testing. This is a bright monitor with a sharp picture and accurate DCI-P3 and sRGB color.

Currently going for $660(opens in new tab), the ViewSonic Elite XG350R-C is cheaper than many other 35-inch ultrawides and ultrawides with fewer features (there’s even RGB lighting on the back of the XG350R-C). But what you’ll really love about the XG350R-C is its vivid and accurate color that makes textures pop, skin tones look natural, and everything looks more realistic.

If you’ve wanted to try out an HDR monitor but can’t afford the best HDR monitors with FALD backlights, the ViewSonic Elite XG270QC (available here(opens in new tab)) is worth a look. Admittedly, it’s not quite FALD-quality, but with edge-lit backlighting, the runner-up, and a VA panel, this monitor’s HDR performance will give you a noticeable upgrade over SDR.

This monitor kept up with other 165 Hz screens in our benchmarks, such as the Dell S3220DGF above. ViewSonic"s XG270QC also delivers 1440p resolution with on-point gamma. Even without HDR, contrast hit 2,897:1 with our calibration settings. Plus, you get a surprisingly loud pair of 3W speakers.

The Asus TUF Gaming VG259QM isn’t the only 240 Hz monitor here, but it’s the only one that overclocks to an impressive 280 Hz so impressively. It’s not only about the high refresh rate, though. It’s also the ability to incorporate FreeSync (despite lacking certification) or G-Sync Compatibility alongside Asus’ Extreme Low Motion Blur (ELMB) feature that bests any monitor’s overdrive. With those features and 280 Hz, our inputs almost felt predicted. This is the kind of monitor that could help your game. Asus’ VG259QM topped our response time test and did admirably in terms of absolute input lag.

One of the downsides of this monitor is its HDR capability. Using an IPS panel with 1,000:1 contrast and only DisplayHDR 400 certification, HDR won’t look much better than SDR content. And, of course, you’ll need a decent graphics card to make the most out of this high-refresh screen.

If you"re the kind of gamer who can take advantage of things like 8,000 Hz mice, the most advanced GPU, and play at a competitive level, the MSI Oculux NXG253R is as good as it gets. We’ve tested a few 360 Hz monitors, namely the Asus ROG Swift PG259QN, Alienware AW2521H, and Acer Predator X25, and they’re all amazingly fast and impressive. However, MSI’s 360 Hz monitor stands above them all as the fastest screen we’ve ever tested.

Our benchmarking recorded the NXG253R’s absolute input lag at 17ms, 1ms faster than the next fastest 360 Hz monitor (Asus’ PG259QN). The NXG253R matched the other 360 Hz screens with a 3ms result when it came to response time. You also get Nvidia’s Reflexlatency analyzer, plus G-Sync all the way down to 1 Hz. Nothing is missing for gaming performance here.

There are some things missing, though. Despite the high price (especially for a 1080p monitor), the NXG253R doesn’t have speakers. And its color gamut is sRGB, rather than the more colorful DCI-P3 that’s increasingly popular among gaming monitors. But this is still a bright screen with decent contrast (1,190.6:1) for an IPS panel. HDR is aided by a variable backlight, which brings contrast to a high 7,972.5:1 with HDR content.

The Samsung 27-inch CRG5 provides incredible speed at 1080p resolution, and the Porsche Design AOC Agon PD27 takes things to the next level, including a higher resolution, shorter response time, and a price tag that’s more than twice the size.

For most, the CRG5 is in the sweet spot for a 240Hz monitor. Its 1080p resolution will require less graphics power than the 1440p PD27. When it came to our speed benchmarks, the PD27 was 1ms faster than the CRG5 in the response time test and 2ms slower in the absolute input lag test. So performance there is comparable, but the PD27 is also in a different style class.

With a unique metallic stand reminiscent of a racecar’s roll cage, LED lighting, including a projector that casts a customizable Porsche Design logo, and even its own remote, this monitor is as much about premium looks as it is about premium performance. If you want a little bit of it everything, it’s tough to beat this stylish monitor.

When shopping for a gaming monitor, you’ll undoubtedly come across a few displays advertising Nvidia’s G-Sync technology. In addition to a hefty price hike, these monitors usually come with gaming-focused features like a fast response time and high refresh rate. To help you know where your money is going, we put together a guide to answer the question: What is G-Sync?

In short, G-Sync is a hardware-based adaptive refresh technology that helps prevent screen tearing and stuttering. With a G-Sync monitor, you’ll notice smoother motion while gaming, even at high refresh rates.

G-Sync is Nvidia’s hardware-based monitor syncing technology. G-Sync solves screen tearing mainly, synchronizing your monitor’s refresh rate with the frames your GPU is pushing out each second.

Your GPU renders a number of frames each second, and put together, those frames give the impression of smooth motion. Similarly, your monitor refreshes a certain number of times each second, clearing the previous image for the new frames your GPU is rendering. To keep things moving smoothly, your GPU stores upcoming frames in a buffer. The problem is that the buffer and your monitor’s refresh rate may get out of sync, causing a nasty line of two frames stitched together.

V-Sync emerged as a solution. This software-based feature essentially forces your GPU to hold frames in its buffer until your monitor is ready to refresh. That solves the screen tearing problem, but it introduces another: Input lag. V-Sync forces your GPU to hold frames it has already rendered, which causes a slight delay between what’s happening in the game and what you see on screen.

Nvidia’s first alternative to V-Sync was Adaptive VSync. Like the older technology, Nvidia’s driver-based solution locked the frame rate to the display’s refresh rate to prevent screen tearing. However, when the GPU struggled, Adaptive VSync unlocked the frame rate until the GPU’s performance improved. Once stable, Adaptive VSync locked the frame rate until the GPU’s performance dropped again.

Nvidia introduced a hardware-based solution in 2013 called G-Sync. It’s based on VESA’s Adaptive-Sync technology, which enables variable refresh rates on the display side. Instead of forcing your GPU to hold frames, G-Sync forces your monitor to adapt its refresh rate depending on the frames your GPU is rendering. That deals with input lag and screen tearing.

However, Nvidia uses a proprietary board that replaces the typical scaler board, which controls everything within the display like decoding image input, controlling the backlight, and so on. A G-Sync board contains 768MB of DDR3 memory to store the previous frame so that it can be compared to the next incoming frame. It does this to decrease input lag.

On the PC end, Nvidia’s driver can fully control the display’s proprietary board. It manipulates the vertical blanking interval, or VBI, which represents the interval between the time when a monitor finishes drawing the current frame and the beginning of the next frame.

With G-Sync active, the monitor becomes a slave to your PC. As the GPU rotates the rendered frame into the primary buffer, the display clears the old image and gets ready to receive the next frame. As the frame rate speeds up and slows down, the display renders each frame accordingly as instructed by your PC. Since the G-Sync board suppor
