not supported with g sync lcd panel manufacturer

I"m the process of buying a secondhand Alienware 15 r3 laptop. On my first visit to the seller, I was disappointed to discover that even though the laptop had both a iGPU and a dGPU, there was no way to switch (MUX switch) the graphics from the dGPU.

Information on this error message is REALLY sketchy online. Some say that the G-Sync LCD panel is hardwired to the dGPU and that the iGPU is connected to nothing. Some say that dGPU is connected to the G-Sync LCD through the iGPU. Some say that they got the MUX switch working after an intention ordering of bios update, iGPU drivers then dGPU drivers on a clean install.

I"m suspecting that if I connect an external 60hz IPS monitor to one of the display ports on the laptop and make it the only display, the Fn+F7 key will actually switch the graphics because the display is not a G-Sync LCD panel. Am I right on this?

If I"m right on this, does that mean that if I purchase this laptop, order a 15inch Alienware 60hz IPS screen and swap it with the FHD 120+hz screen currently inside, I will also continue to have MUX switch support and no G-Sync? The price for these screens is not outrageous.

If you want smooth gameplay without screen tearing and you want to experience the high frame rates that your Nvidia graphics card is capable of, Nvidia’s G-Sync adaptive sync tech, which unleashes your card’s best performance, is a feature that you’ll want in your next monitor.

To get this feature, you can spend a lot on a monitor with G-Sync built in, like the high-end $1,999 Acer Predator X27, or you can spend less on a FreeSync monitor that has G-Sync compatibility by way of a software update. (As of this writing, there are 15 monitors that support the upgrade.)

However, there are still hundreds of FreeSync models that will likely never get the feature. According to Nvidia, “not all monitors go through a formal certification process, display panel quality varies, and there may be other issues that prevent gamers from receiving a noticeably improved experience.”

But even if you have an unsupported monitor, it may be possible to turn on G-Sync. You may even have a good experience — at first. I tested G-Sync with two unsupported models, and, unfortunately, the results just weren’t consistent enough to recommend over a supported monitor.

The 32-inch AOC CQ32G1 curved gaming monitor, for example, which is priced at $399, presented no issues when I played Apex Legends and Metro: Exodus— at first. Then some flickering started appearing during gameplay, though I hadn’t made any changes to the visual settings. I also tested it with Yakuza 0,which, surprisingly, served up the worst performance, even though it’s the least demanding title that I tested. Whether it was in full-screen or windowed mode, the frame rate was choppy.

Another unsupported monitor, the $550 Asus MG279Q, handled both Metro: Exodus and Forza Horizon 4 without any noticeable issues. (It’s easy to confuse the MG279Q for the Asus MG278Q, which is on Nvidia’s list of supported FreeSync models.) In Nvidia’s G-Sync benchmark, there was significant tearing early on, but, oddly, I couldn’t re-create it.

Before you begin, note that in order to achieve the highest frame rates with or without G-Sync turned on, you’ll need to use a DisplayPort cable. If you’re using a FreeSync monitor, chances are good that it came with one. But if not, they aren’t too expensive.

First, download and install the latest driver for your GPU, either from Nvidia’s website or through the GeForce Experience, Nvidia’s Windows 10 app that can tweak graphics settings on a per-game basis. All of Nvidia’s drivers since mid-January 2019 have included G-Sync support for select FreeSync monitors. Even if you don’t own a supported monitor, you’ll probably be able to toggle G-Sync on once you install the latest driver. Whether it will work well after you do turn the feature on is another question.

Once the driver is installed, open the Nvidia Control Panel. On the side column, you’ll see a new entry: Set up G-Sync. (If you don’t see this setting, switch on FreeSync using your monitor’s on-screen display. If you still don’t see it, you may be out of luck.)

Check the box that says “Enable G-Sync Compatible,” then click “Apply: to activate the settings. (The settings page will inform you that your monitor is not validated by Nvidia for G-Sync. Since you already know that is the case, don’t worry about it.)

Check that the resolution and refresh rate are set to their max by selecting “Change resolution” on the side column. Adjust the resolution and refresh rate to the highest-possible option (the latter of which is hopefully at least 144Hz if you’ve spent hundreds on your gaming monitor).

Nvidia offers a downloadable G-Sync benchmark, which should quickly let you know if things are working as intended. If G-Sync is active, the animation shouldn’t exhibit any tearing or stuttering. But since you’re using an unsupported monitor, don’t be surprised if you see some iffy results. Next, try out some of your favorite games. If something is wrong, you’ll realize it pretty quickly.

There’s a good resource to check out on Reddit, where its PC community has created a huge list of unsupported FreeSync monitors, documenting each monitor’s pros and cons with G-Sync switched on. These real-world findings are insightful, but what you experience will vary depending on your PC configuration and the games that you play.

Make sure the monitor supports Nvidia’s G-Sync technology - a list of supported monitors at the time of this article can be found on Nvidia"s website.

Make sure a DisplayPort cable is being used - G-Sync is only compatible with DisplayPort. It must be a standard DisplayPort cable using no adapters or conversions. HDMI, DVI and VGA are not supported.

Under the Display tab on the left side of the Nvidia Control Panel, choose Set up G-Sync, followed by Enable G-Sync, G-Sync Compatible checkbox. Note: If the monitor has not been validated as G-Sync Compatible, select the box under Display Specific Settings to force G-Sync Compatible mode on. See the warning NOTE at the end of the article before proceeding.

NOTE: If the monitor supports VRR (Variable Refresh Rate) technologies but is not on the list above, use caution before proceeding. It may still work, however there may be issues when using the technology. Known issues include blanking, pulsing, flickering, ghosting and visual artifacts.

I got a refurbished Alienware 15 R3 today, when i placed the order i made sure to look for one which doesn"t have a g-sync display so i can switch off the dedicated gpu in order to save battery, however when i got the laptop and tried switching to the internal gpu it doesn"t give me the option and only lets me use the dedicated one.

At first i thought that maybe i was sent a laptop with a g-sync display but when i checked in device manager the display is listed as "generic pnp display" no mention of g-sync yet i cant seem to be able to turn off the gpu and whenever i press fn+f7 i get the following message "not supported with g-sync ips display" even though the display is not a g-sync display.

At CES 2019, Nvidia announced its software-based version of G-Sync that extended VRR (Variable Refresh Rate) support for Nvidia GPUs on AMD FreeSync monitors. However, initial impressions were a tad bit underwhelming as the company validated only a handful of FreeSync panels that can run G-Sync to its full extent, without resorting to any major compatibility issues.

Now comes the question: is it possible to activate Nvidia"s Adaptive-Sync technology on a FreeSync display that hasn"t been certified as G-Sync Compatible? Let"s find out!

To maintain exclusivity of its proprietary Adaptive-Sync solution, Nvidia"s G-Sync technology has been categorized across three different tiers: G-Sync, G-Sync Compatible, and G-Sync Ultimate. While both G-Sync and G-Sync Ultimate monitors feature a dedicated module to drive VRR, G-Sync Compatible monitors are essentially FreeSync panels that have been validated by Nvidia to run G-Sync through its rigorous testing methodology.

In case you"re wondering, Nvidia"s G-Sync Compatibility program, which was introduced back in 2019, aims to certify a wide range of FreeSync monitors based on specific parameters. For starters, every G-Sync Compatible monitor should be able to deliver a baseline VRR experience without incurring any visual artifacts such as pulsing, flickering, blanking, or ghosting.

Furthermore, the retroactive program also validates whether a FreeSync display can operate across a VRR range of at least 2.4:1. Such calculations are performed by dividing the maximum refresh rate of a monitor to its minimum refresh rate within the VRR range.

For instance, if your FreeSync monitor supports a wide VRR range of 48-144Hz, which is greater than Nvidia"s recommended value of 2.4, G-Sync functionality should be enabled right out-of-the-box. However, if the minimum VRR range went up to 75Hz, which does not comply with Nvidia"s VRR threshold, the display loses an official "G-Sync Compatible" certification.

As of November 2022, Nvidia has validated over 150 FreeSync monitors that can run G-Sync at an adequate VRR range. For more information, check out Nvidia"s official list of FreeSync monitors that have been certified as G-Sync Compatible.

Although official G-Sync Compatibility has its perks on quite a few occasions, it is possible to drive Nvidia"s Adaptive-Sync solution on most non-certified FreeSync monitors, provided that you possess the right set of hardware. Since both FreeSync and G-Sync technologies support VESA"s (Video Electronics Standards Association) Adaptive-Sync protocol, any limitations that you might face are based solely on the manufacturing standards.

Unlike AMD"s FreeSync implementation, which works on both HDMI and DisplayPort (over USB Type-C as well), Nvidia"s proprietary Adaptive-Sync solution seems somewhat limited in terms of connectivity. For G-Sync to work on a FreeSync display, ensure that your system meets the following requirements:

Connection Options: DisplayPort 1.2 (or higher) for AMD FreeSync monitors. HDMI 2.0/2.1 support for G-Sync Compatible TVs and BFGD (Big Format Gaming Displays).

First, download and Install the latest GeForce Game Ready Drivers from Nvidia"s official Driver Downloads page. Alternatively, it is possible to update your GPU drivers by using Nvidia"s own software suite: GeForce Experience.

After installing the latest GPU drivers, restart your PC and check whether FreeSync (Basic or Extended) has been enabled from the monitor"s OSD (On-Screen Display).

For G-Sync Compatible monitors, G-Sync should be enabled by default when FreeSync has been activated from the monitor"s OSD. However, if you are using a non-certified FreeSync display, you might need to change additional settings inside the Nvidia Control Panel. Right-click on the desktop and select NVIDIA Control Panel from the drop-down menu.

Inside the NVIDIA Control Panel, go to Manage 3D settings and look for Monitor Technology under the Global Settings tab. Set G-SYNC Compatible as the preferred option.

On an additional note, check whether Preferred refresh rate has been set to Highest available. Doing so allows your FreeSync monitor to take advantage of its maximum refresh rate.

For an optimal G-Sync experience, we recommend using V-Sync along with G-Sync to eliminate screen tearing when the frame rate goes above the VRR range. Under Global Settings, scroll down to the bottom of the list and set Vertical sync to On. Click on Applyto save your changes.

After modifying these settings, click on Set up G-SYNC under the Displaytab. In case you"re using multiple monitors, select your primary display and click on the checkbox, right next to Enable G-SYNC, G-SYNC Compatible.

Since most non-certified FreeSync monitors suffer from major flickering issues when running G-Sync in windowed mode, it is advisable to enable G-Sync functionality exclusively for full screen mode. When you"re done making these changes, click on the checkbox next to Enable settings for the selected display model and then on Apply to save your preferences.

To test whether G-Sync is working properly on your FreeSync display, download and install Nvidia"s G-SYNC Pendulum demo, a handy tool that can help demonstrate the benefits of Adaptive-Sync technology. Consider switching between No Vsync and G-SYNC to better understand the purpose of G-Sync in synchronizing your monitor"s refresh rate with the frame rate of your GPU.

Now, one of the major concerns for PC gamers when using V-Sync alongside G-Sync is the introduction of input lag. Not only does it contribute to additional system latency but also affects the overall experience by a significant margin.

To reduce any V-Sync level input lag while gaming on a FreeSync display, set the maximum frame rate to three frames below the monitor"s refresh rate. For a 144Hz monitor, an FPS cap of 141 should be good enough for consistent frame pacing across the board.

If your game doesn"t include an internal FPS limiter, try using an external frame rate limiter such as RTSS (Rivatuner Statistics Server) or Nvidia"s Max Frame Rate option inside the Control Panel.

Despite Nvidia"s claims about a suboptimal gaming experience when running G-Sync on non-certified FreeSync panels, we found little to no difference between both variants. Besides exclusive features such as ULMB (Ultra Low Motion Blur) and Variable Overdrive support, Nvidia GPUs tend to provide a similar VRR experience as AMD GPUs on most FreeSync monitors.

Instead of going for a premium G-Sync monitor, you can save a large portion of your budget by opting for a FreeSync (Premium/Premium Pro) display that will deliver the best of both worlds.

It’s difficult to buy a computer monitor, graphics card, or laptop without seeing AMD FreeSync and Nvidia G-Sync branding. Both promise smoother, better gaming, and in some cases both appear on the same display. But what do G-Sync and FreeSync do, exactly – and which is better?

Most AMD FreeSync displays can sync with Nvidia graphics hardware, and most G-Sync Compatible displays can sync with AMD graphics hardware. This is unofficial, however.

The first problem is screen tearing. A display without adaptive sync will refresh at its set refresh rate (usually 60Hz, or 60 refreshes per second) no matter what. If the refresh happens to land between two frames, well, tough luck – you’ll see a bit of both. This is screen tearing.

Screen tearing is ugly and easy to notice, especially in 3D games. To fix it, games started to use a technique called V-Syncthat locks the framerate of a game to the refresh rate of a display. This fixes screen tearing but also caps the performance of a game. It can also cause uneven frame pacing in some situations.

Adaptive sync is a better solution. A display with adaptive sync can change its refresh rate in response to how fast your graphics card is pumping out frames. If your GPU sends over 43 frames per second, your monitor displays those 43 frames, rather than forcing 60 refreshes per second. Adaptive sync stops screen tearing by preventing the display from refreshing with partial information from multiple frames but, unlike with V-Sync, each frame is shown immediately.

Enthusiasts can offer countless arguments over the advantages of AMD FreeSync and Nvidia G-Sync. However, for most people, AMD FreeSync and Nvidia G-Sync both work well and offer a similar experience. In fact, the two standards are far more similar than different.

All variants of AMD FreeSync are built on the VESA Adaptive Sync standard. The same is true of Nvidia’s G-Sync Compatible, which is by far the most common version of G-Sync available today.

VESA Adaptive Sync is an open standard that any company can use to enable adaptive sync between a device and display. It’s used not only by AMD FreeSync and Nvidia G-Sync Compatible monitors but also other displays, such as HDTVs, that support Adaptive Sync.

AMD FreeSync and Nvidia G-Sync Compatible are so similar, in fact, they’re often cross compatible. A large majority of displays I test with support for either AMD FreeSync or Nvidia G-Sync Compatible will work with graphics hardware from the opposite brand.

AMD FreeSync and Nvidia G-Sync Compatible are built on the same open standard. Which leads to an obvious question: if that’s true, what’s the difference?

Nvidia G-Sync Compatible, the most common version of G-Sync today, is based on the VESA Adaptive Sync standard. But Nvidia G-Sync and G-Sync Ultimate, the less common and more premium versions of G-Sync, use proprietary hardware in the display.

This is how all G-Sync displays worked when Nvidia brought the technology to market in 2013. Unlike Nvidia G-Sync Compatible monitors, which often (unofficially) works with AMD Radeon GPUs, G-Sync is unique and proprietary. It only supports adaptive sync with Nvidia graphics hardware.

It’s usually possible to switch sides if you own an AMD FreeSync or Nvidia G-Sync Compatible display. If you buy a G-Sync or G-Sync Ultimate display, however, you’ll have to stick with Nvidia GeForce GPUs. (Here’s our guide to the best graphics cards for PC gaming.)

This loyalty does net some perks. The most important is G-Sync’s support for a wider range of refresh rates. The VESA Adaptive Sync specification has a minimum required refresh rate (usually 48Hz, but sometimes 40Hz). A refresh rate below that can cause dropouts in Adaptive Sync, which may let screen tearing to sneak back in or, in a worst-case scenario, cause the display to flicker.

G-Sync and G-Sync Ultimate support the entire refresh range of a panel – even as low as 1Hz. This is important if you play games that may hit lower frame rates, since Adaptive Sync matches the display refresh rate with the output frame rate.

For example, if you’re playing Cyberpunk 2077 at an average of 30 FPS on a 4K display, that implies a refresh rate of 30Hz – which falls outside the range VESA Adaptive Sync supports. AMD FreeSync and Nvidia G-Sync Compatible may struggle with that, but Nvidia G-Sync and G-Sync Ultimate won’t have a problem.

AMD FreeSync Premium and FreeSync Premium Pro have their own technique of dealing with this situation called Low Framerate Compensation. It repeats frames to double the output such that it falls within a display’s supported refresh rate.

Other differences boil down to certification and testing. AMD and Nvidia have their own certification programs that displays must pass to claim official compatibility. This is why not all VESA Adaptive Sync displays claim support for AMD FreeSync and Nvidia G-Sync Compatible.

AMD FreeSync and Nvidia G-Sync include mention of HDR in their marketing. AMD FreeSync Premium Pro promises “HDR capabilities and game support.” Nvidia G-Sync Ultimate boasts of “lifelike HDR.”

This is a bunch of nonsense. Neither has anything to do with HDR, though it can be helpful to understand that some level of HDR support is included in those panels. The most common HDR standard, HDR10, is an open standard from the Consumer Technology Association. AMD and Nvidia have no control over it. You don’t need FreeSync or G-Sync to view HDR, either, even on each company’s graphics hardware.

PC gamers interested in HDRshould instead look for VESA’s DisplayHDR certification, which provides a more meaningful gauge of a monitor’s HDR capabilities.

Both standards are plug-and-play with officially compatible displays. Your desktop’s video card will detect that the display is certified and turn on AMD FreeSync or Nvidia G-Sync automatically. You may need to activate the respective adaptive sync technology in your monitor settings, however, though that step is a rarity in modern displays.

Displays that support VESA Adaptive Sync, but are not officially supported by your video card, require you dig into AMD or Nvidia’s driver software and turn on the feature manually. This is a painless process, however – just check the box and save your settings.

AMD FreeSync and Nvidia G-Sync are also available for use with laptop displays. Unsurprisingly, laptops that have a compatible display will be configured to use AMD FreeSync or Nvidia G-Sync from the factory.

A note of caution, however: not all laptops with AMD or Nvidia graphics hardware have a display with Adaptive Sync support. Even some gaming laptops lack this feature. Pay close attention to the specifications.

VESA’s Adaptive Sync is on its way to being the common adaptive sync standard used by the entire display industry. Though not perfect, it’s good enough for most situations, and display companies don’t have to fool around with AMD or Nvidia to support it.

That leaves AMD FreeSync and Nvidia G-Sync searching for a purpose. AMD FreeSync and Nvidia G-Sync Compatible are essentially certification programs that monitor companies can use to slap another badge on a product, though they also ensure out-of-the-box compatibility with supported graphics card. Nvidia’s G-Sync and G-Sync Ultimate are technically superior, but require proprietary Nvidia hardware that adds to a display’s price. This is why G-Sync and G-Sync Ultimate monitors are becoming less common.

My prediction is this: AMD FreeSync and Nvidia G-Sync will slowly, quietly fade away. AMD and Nvidia will speak of them less and lesswhile displays move towards VESA Adaptive Sync badgesinstead of AMD and Nvidia logos.

If that happens, it would be good news for the PC. VESA Adaptive Sync has already united AMD FreeSync and Nvidia G-Sync Compatible displays. Eventually, display manufacturers will opt out of AMD and Nvidia branding entirely – leaving VESA Adaptive Sync as the single, open standard. We’ll see how it goes.

There are four different possibilities of results for this test. Each result tells us something different about the monitor, and while native FreeSync monitors can still work with NVIDIA graphics cards, there are a few extra advantages you get with a native G-SYNC monitor too.

No:Some displays simply aren"t compatible with NVIDIA"s G-SYNC technology as there"s screen tearing. This is becoming increasingly rare, as most monitors at least work with G-SYNC.

Compatible (NVIDIA Certified):NVIDIA officially certifies some monitors to work with their G-SYNC compatible program, and you can see the full list of certified monitors here. On certified displays, G-SYNC is automatically enabled when connected to at least a 10-series NVIDIA card over DisplayPort. NVIDIA tests them for compatibility issues and only certifies displays that work perfectly out of the box, but they lack the G-SYNC hardware module found on native G-SYNC monitors.

The simplest way to validate that a display is officially G-SYNC compatible is to check the "Set up G-SYNC" menu from the NVIDIA Control Panel. G-SYNC will automatically be enabled for a certified compatible display, and it"ll say "G-SYNC Compatible" under the monitor name. Most of the time, this works only over DisplayPort, but with newer GPUs, it"s also possible to enable G-SYNC over HDMI with a few monitors and TVs, but these are relatively rare.

Compatible (Tested):Monitors that aren"t officially certified but still have the same "Enable G-SYNC, G-SYNC Compatible" setting in the NVIDIA Control Panel get "Compatible (Tested)" instead of "NVIDIA Certified". However, you"ll see on the monitor name that there isn"t a certification here. There isn"t a difference in performance between the two sets of monitors, and there could be different reasons why it isn"t certified by NVIDIA, including NVIDIA simply not testing it. As long as the VRR support works over its entire refresh rate range, the monitor works with an NVIDIA graphics card.

Yes (Native):Displays that natively support G-SYNC have a few extra features when paired with an NVIDIA graphics card. They can dynamically adjust their overdrive to match the content, ensuring a consistent gaming experience. Some high refresh rate monitors also support the NVIDIA Reflex Latency Analyzer to measure the latency of your entire setup.

Like with certified G-SYNC compatible monitors, G-SYNC is automatically enabled on Native devices. Instead of listing them as G-SYNC Compatible in the "Set up G-SYNC page", Native monitors are identified as simply "G-SYNC Capable" below the monitor name. We don"t specify if it has a standard G-SYNC certification or G-SYNC Ultimate, as both are considered the same for this testing.

For this test, we ensure G-SYNC is enabled from the NVIDIA Control Panel and use the NVIDIA Pendulum Demo to ensure G-SYNC is working correctly. If we have any doubts, we"ll check with a few games to ensure it"s working with real content.

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.

G-Sync is a proprietary adaptive sync technology developed by Nvidia aimed primarily at eliminating screen tearing and the need for software alternatives such as Vsync.video display"s refresh rate to adapt to the frame rate of the outputting device (graphics card/integrated graphics) rather than the outputting device adapting to the display, which could traditionally be refreshed halfway through the process of a frame being output by the device, resulting in screen tearing, or two or more frames being shown at once.AMD has released a similar technology for displays, called FreeSync, which has the same function as G-Sync yet is royalty-free.

Nvidia built a special collision avoidance feature to avoid the eventuality of a new frame being ready while a duplicate is being drawn on screen (something that could generate lag and/or stutter) in which case the module anticipates the refresh and waits for the next frame to be completed.Overdriving pixels also becomes tricky in a non-fixed refresh scenario, and solutions predicting when the next refresh is going to happen and accordingly adjusting the overdrive value must be implemented and tuned for each panel in order to avoid ghosting.

The module carries all the functional parts. It is based around an Altera Arria V GX family FPGA featuring 156K logic elements, 396 DSP blocks and 67 LVDS channels. It is produced on the TSMC 28LP process and paired with three DDR3L DRAM chips to attain a certain bandwidth, for an aggregate 768MB capacity. The employed FPGA also features a LVDS interface to drive the monitor panel. It is meant to replace common scalers and be easily integrated by monitor manufacturers, who only have to take care of the power delivery circuit board and input connections.

G-Sync faces some criticismVESA standard Adaptive-Sync which is an optional feature of DisplayPort version 1.2a.AMD"s FreeSync relies on the above-mentioned optional component of DisplayPort 1.2a, G-Sync requires an Nvidia-made module in place of the usual scaler in the display in order for it to function properly with select Nvidia GeForce graphics cards, such as the ones from the GeForce 10 series (Pascal).JayzTwoCents showed that monitors with the G-Sync module draw approximately 14W continuously when the monitor is off, and that comparable monitors without the G-Sync module draw 0.0W when the monitor is off.

Nvidia announced that G-Sync will be available to notebook manufacturers and that in this case, it would not require a special module since the GPU is directly connected to the display without a scaler in between.

According to Nvidia, fine tuning is still possible given the fact that all notebooks of the same model will have the same LCD panel, variable overdrive will be calculated by shaders running on the GPU, and a form of frame collision avoidance will also be implemented.

At CES 2018 Nvidia announced a line of large gaming monitors built by HP, Asus and Acer with 65-inch panels, 4K, HDR, as well as G-Sync support. The inclusion of G-Sync modules make the monitors among the first TV-sized displays to feature variable refresh-rates.

At CES 2019, Nvidia announced that they will support variable refresh rate monitors with FreeSync technology under a new standard named G-Sync Compatible. All monitors under this new standard have been tested by Nvidia to meet their baseline requirements for variable refresh rate and will enable G-Sync automatically when used with an Nvidia GPU.

G-Sync is a must-have feature in a gaming monitor if you own an Nvidia graphics card. It synchronizes the refresh rate of your display with the frame rate of the games you play, smoothing away stuttering and screen tearing. Believe it or not, these problems were the norm as recently as a decade ago.

However, choosing the right G-Sync gaming monitor can be complex. You must select from several levels of G-Sync certification while also separating out great FreeSync gaming monitors that work with AMD’s video cards. If you don’t want to dig into the details, however, we’ve done the legwork for you and picked out the best G-sync gaming monitors – and click here to see them in the UK.

There are a plethora of G-Sync gaming monitors out there, and the Viewsonic Elite XG270Q ticks all the right boxes. It offers a 27-inch display with 1440p resolution, hitting that sweet spot of a fast refresh rate without sacrificing a sharp image. The true G-Sync module handles any refresh rate from 1Hz and is overclockable to 165Hz. That pairs well with the wickedly fast response time, resulting in a superbly smooth gameplay experience that any gamer will love.

This monitor also stands out for its image quality. It uses a Nano IPS panel with an extremely wide color gamut, great color accuracy, and high maximum brightness, though you don’t get local dimming or HDR. Similar to most IPS panels, it doesn’t offer the deepest blacks, but that issue can be somewhat remedied by the bias lighting available on the back of the display. That lighting is actually RGB lighting, so you can amp up the gamer aesthetic if you prefer.

The Viewsonic Elite XG270Q is a sturdy display with a great stand that’s height, tilt, and swivel adjustable. Unlike some rivals, its design doesn’t scream, “I’m a gaming monitor!” It totes two video ports; a DisplayPort 1.2 and HDMI 1.4 port. There’s also a USB hub for up to three wired USB-A peripherals.

You don’t need to spend a fortune for a smooth gaming experience, and the Asus VG248QG is proof of this. This ergonomic 23.8-inch monitor is the predecessor of one of our previous favorites, the Asus VG248QE. Its latest iteration offers 1080p, 165Hz, and uses a TN panel to shave the price below $200. Though it"s not the largest or most capable monitor out there, it sure beats the typical boring 24-inch, 60Hz office monitor.

You get G-Sync compatibility with this option, the least strenuous of the G-Sync standards available. However, the support of any refresh rate between 1Hz and 165Hz using the DisplayPort connection provides a broad frame rate range and prevents screen tearing. The HDMI port doesn’t support G-Sync, but there’s also native FreeSync if you’ve got an AMD graphics card in another rig. You get smooth motion due to a speedy response time, and input lag is low for responsive gaming. Therefore, you’re getting an overall pleasant gaming experience.

The downside? Image quality is not the best out there, and the viewing angles are limited. Its TN panel doesn’t handle contrast ratio well, and you don’t get deep blacks. However, for budget competitive gaming, motion clarity is key, not image quality, so this is the perfect monitor.

The Acer Predator XB253Q GW remains our go-to recommendation for a mid-range 1080p gaming monitor. The 24.5-inch display earns the nod largely on its image quality and impressive refresh rate of 280Hz. The monitor has great color accuracy, outstanding motion clarity, and a good contrast ratio—for an IPS panel, at least. It also gets pretty bright and supports HDR gaming, though you don’t get backlight dimming.

This G-Sync compatible monitor doesn’t have a full G-Sync module baked in. The lack of a true G-Sync is disappointing, but that ups the price of a monitor quickly. It still works with G-Sync at a refresh rate between 50Hz and 240Hz, but when you overclock to 280Hz, you do lose support. The 50Hz lower limit on G-Sync compatibility shouldn’t be an issue with most games, as running games at 1080p isn’t very demanding. That solid motion clarity and a quick response time should keep you immersed in the action for hours.

This monitor is built like a tank, and the stand lets you get the proper ergonimics to be comfortable during marathon gaming sessions. There’s plenty of connectivity, including two HDMI 2.0 ports and a DisplayPort 1.2 that supports the 280Hz refresh rate. Beyond that, there’s an audio out jack and four USB Type-A ports—two on the side bezel and two around the back.

Alienware’s AW2721D is a fantastic gaming monitor and nearly bumped the Viewsonic XG270QG from its top spot. The Viewsonic edged out due to its lower price, but AW2721D is a great alternative. Its 27-inch, 1440p display manages a solid contrast ratio and gets surprisingly deep blacks for an IPS panel. It even totes local backlight dimming. The high pixel density, brightness, and color performance further solidify it as an ideal choice for gaming.

Speaking of gaming, this monitor is Nvidia G-Sync Ultimate certified, supporting G-Sync at any refresh rate between 1Hz and 240Hz on the DisplayPort and includes HDR. The two HDMI ports drop you down to 144Hz, but you’ll still see smooth gameplay in every game, all the time. HDR support is a nice bonus, though it’s only on par with budget HDR TVs. Still, the image quality looks excellent and it’s similar to the Viewsonic XG270QG.

The Alienware has a unique look and class-leading build quality. There’s even some RGB lighting that can be customized through AlienFX software. It also supports two USB Type-A ports for wired gaming peripherals.

It’s difficult to find a great 4K monitor with official G-Sync certification, a somewhat reasonable price, and available stock, but the Asus ROG Swift PG32UQ fits the bill. This big 32-inch, 4K monitor stands out most because of its outrageously sharp, bright, and vibrant image. Color performance is excellent, and the monitor’s high 600 nits maximum brightness adds punchy visuals to HDR games.

Going 4K means sacrificing frame rates, but the 144Hz on this monitor still provides a smooth, enjoyable gaming experience. It’s a G-Sync Compatible option that supports G-Sync at a refresh rate between 48Hz to 144Hz. You may likely see issues at low framerates with this monitor’s high native resolution, but that can be avoided by upgrading to a much more expensive monitor like the Asus ROG Swift PG32UQX. Other gaming features include a low 1ms response time to eliminate smearing and motion blur and auto low latency for lag-free gaming.

As for build quality, this monitor is rock solid and has a stable, height-adjustable stand. Connectivity is a bit bare as it includes two USB Type-A ports for connecting wired gaming peripherals beyond its two HDMI 2.1 that only support 120Hz native refresh rate and one DisplayPort.

Gamers don’t need to choose between AMD FreeSync and Nvidia G-Sync, as Samsung’s Odyssey G7 shows it"s possible to have both in one excellent display. This gaming monitor has class-leading image quality and offers smooth gameplay with AMD and Nvidia hardware. The G-Sync Compatibility between a refresh rate of 60Hz and 240Hz is a bit high, so you’ll want to pair the monitor with a fast video card for best results. Nvidia fans should note the 32-inch model has a higher minimum of 80Hz, which is why we recommend the smaller monitor for use with G-Sync.

Sticking with a 1440p monitor aids in the impressive frame rates and helps games run better. Those speeds, alongside a 600-nit peak brightness and 10-bit color depth on the VA panel mean you’ll not only be able to see a ton of frames, but each frame can look exceptional. There are also deep blacks and decent pixel density on the 27-inch model for a better viewing experience.

Samsung’s Odyssey G7 is an eye-catching display even when it’s off. It has an aggressive curve for immersive gaming and delivers an attractive design with good build quality. The monitor has two USB Type-A ports for connecting wired peripherals, while the two HDMIs or DisplayPort are great for hooking up your rig.

Gaming on an ultrawide monitor, like the Alienware AW3821DW, gets you far more immersed in the action than a traditional monitor. This 38-inch ultrawide monster boasts 3,840 x 1,600 resolution for a sharp, crisp image and a 21:9 aspect ratio with a slight curve to wrap your games around your field of vision. Beyond its ample display real estate, you get decent color performance, a high maximum brightness—it totes HDR600—and superb motion clarity with its G-Sync Ultimate support.

If you’re gaming on an Nvidia GPU, this G-Sync Ultimate monitor works with a refresh rate of 1Hz all the way up to 144Hz, so you’re in for ultra-smooth, stutter-free gameplay. It works perfectly in pretty much every game in full-screen or windowed mode. Its HDR performance in compatible games is respectable and provides a punchy look, though it’s nothing to rave about.

Alienware’s outstanding build quality is in full force here. It’s a massive, hefty monitor, so much so that you may need to rearrange your desk or gaming den to make it fit. Luckily, the stand is height, tilt, and swivel adjustable, making it easier to get the most comfortable viewing angles. The monitor only offers two USB ports, which is a bit disappointing, but they use the more capable USB 3.2 Gen 1 standard—most monitors stick to USB 3.0 or 3.1.

If you’re often playing League of Legends, Overwatch, or other fast-paced esports games, it’s important to grab a monitor with a high refresh rate over a high resolution. Luckily, the Asus ROG Swift PG259QN offers an absurdly fast 360fps for smooth, virtually blur-free motion—if your GPU can even keep up with those speeds. That’s paired with an equally stellar response time for virtually no flickering.

This monitor offers a G-Sync module, which means G-Sync will work at any refresh rate between 1Hz and 360Hz. That’s the widest range of G-Sync compatibility you’ll find on any monitor. The result is super-smooth gaming that always takes full advantage of your Nvidia video card’s performance. There’s even a G-Sync Esports Mode to get the ideal settings for esports games.

This 24.5-inch, 1080p monitor offers good image quality, and the small size makes it easier to see all the action on screen without constantly moving your eyes back and forth. It has excellent build quality and a large, sturdy stand. The monitor includes two USB ports for connecting wired peripherals, though they’re on the rear and can be a bit difficult to access.

To make the most of G-Sync technology, then the ultra-premium and expensive Asus ROG Swift PG32UQX is the way to go. This monitor totes G-Sync Ultimate, so it’ll work at any refresh rate between 1Hz and 144Hz. This feature is essential, as most video cards will not be able to sustain a high framerate at this monitor’s 4K resolution, and it’s safe to say everyone wants smooth, tear-free gaming. Unlike most G-Sync Ultimate monitors, this monitor can even make the most of HDR. It’s currently the best HDR gaming monitor money can buy.

The PG32UQX rocks a Mini-LED backlight that sets a new standard for contrast ratio and dark scene performance in an IPS gaming monitor. It also blows away the competition when it comes to HDR and has an insane peak brightness. Motion performance is not outstanding, but it’s alright for a 4K monitor, and it’s ultimately about immersive visuals more than split-second responsiveness.

The build quality goes beyond great and into the realm of the absurd. The monitor is massive, thick, and even has a tiny secondary screen that can display information like GPU system temperatures or current framerate. There are three USB ports, one of which is on the top and meant for connecting a webcam.

The LG C2 OLED Evo has more-or-less become the default gaming television. It uses OLED technology for the fastest pixel response time currently available, and you can control color down to each individual pixel. Blacks are truly black, and there’s little worry about annoying “halo” effects around bright objects on dark backgrounds. The absolute contrast also makes colors pop and any scene from bright landscapes and skies to dark caves and creepy basements look incredible.

It’s not only great because of the excellent image quality but also totes strong support for the latest gaming standards, including multiple HDMI 2.1 ports along with Adaptive Sync, FreeSync, and G-Sync. It’s G-Sync compatible and certified to work at a refresh rate between 40Hz and 120Hz. While true G-Sync would’ve been nice, this provides a wide range of refresh rates to work. Large displays with true G-Sync are rare, and those that exist are much more expensive than the LG C2 OLED Evo.

Because it"s a television, not a monitor, the LG C2 OLED Evo’s connectivity is different from other displays listed here. It offers four HDMI ports, all of which support HDMI 2.1 for hooking up your machines, but doesn’t have DisplayPort. It’s a bit pricey, though if you want the best television for gaming with no compromises, this delivers.

Thankfully all of the best monitors listed are also available to pick up in the UK. The retailers will certainly be different, but each and every one of the G-Sync displays we"ve mentioned can be purchased on the other side of the pond as well. Typically, most of these can be found on sites like Amazon, Currys PC World, Overclockers, and more. Funnily enough, Dell even stocks its own products, such as this 24-Inch Gaming Monitor, one of the best options for those on a tight budget.

Nvidia G-Sync comes in three flavors: G-Sync Ultimate, G-Sync, and G-Sync Compatible. It’s important to understand the difference between G-Sync standards before you buy.

The G-Sync Ultimate and G-Sync standards require a dedicated G-Sync hardware module inside the display. This module is a dedicated chip that synchronizes the monitor’s refresh rate with the Nvidia video card’s output.

The G-Sync module’s key benefit is the ability to display smooth motion across a monitor’s entire refresh rate range. You will see smooth, evenly paced gameplay even when a game’s frame rate takes a dip. The motion will not feel as smooth as at a higher framerate, of course, but it will remain free of tearing and stuttering.

G-Sync Ultimate adds image quality standards including HDR and wide color gamut support. This is a sly marketing move from Nvidia, as it suggests these benefits are related to G-Sync. That’s not the case: Nvidia is only certifying the monitor performs to a certain minimum standard. The motion performance of G-Sync Ultimate is the same as standard G-Sync.

G-Sync Compatible is where things get dicey. G-Sync Compatible monitors don’t have a G-Sync module at all and instead rely on the open VESA Adaptive Sync standard. This standard is now common to a wide variety of monitors and, because it doesn’t require a G-Sync module, can hit very low price points.

However, the VESA Adaptive Sync standard does not support refresh rates any lower than 40Hz, and some monitors that are G-Sync compatible have a minimum G-Sync refresh rate even higher than that. G-Sync may not work properly at a framerate below the minimum refresh rate the monitor is G-Sync Compatible monitor is certified to support. You could see flickering or blanking (blank frames) while gaming. Nvidia maintains a database showing the certified specifications of all G-Sync and G-Sync compatible monitors.

Technically, G-Sync Compatible monitors may also have issues when a game’s framerate exceeds a monitor’s refresh rate. This is less frequently an issue, though, and can be addressed with a frame rate cap.

The downsides of G-Sync Compatible monitors are rare in practice. We test dozens of monitors every year at IGN, and it’s unusual that we see flickering or blanking during our review process. Most G-Sync Compatible monitors are certified to work down to a refresh rate of at least 48Hz, which means gameplay should remain smooth and trouble-free at 48 frames per second or above. That’s not a difficult standard to achieve, especially on 1080p and 1440p monitors.

Still, you should keep the difference between G-Sync Compatible and G-Sync in mind. If you want smooth and trouble-free G-Sync in every game, at any frame rate, you’ll want to buy a monitor with G-Sync or G-Sync Ultimate.
