The refresh rate of a monitor is one of the most important metrics to determine the quality of a display. But how do you check the monitor refresh rate?

Simply reading a label is not enough. To determine what the refresh rate of your monitor is in practice, you need to use a tool that checks this performance in real-time. Here are the five best online sites for doing this.

Visuals on a screen are created by displaying multiple still images in sequence. The faster these sequences pass by, the more convincing the illusion, making the video look smoother.

This is known as the frames-per-second, or FPS. But the frame rate of the video or game in question is not the only factor in video quality. The monitor has to be capable of rendering that many frames every second as well.

This is where the refresh rate comes in. Simply put, the refresh rate of a display is the number of frames it can show every second. The higher the refresh rate, the better the picture quality you get. This is why you need to test your display and determine if its refresh rate is actually enough for your gaming or video needs.

This is one of the easiest tests to run, and also one of the most accurate. Just open the site and let it work its magic. TestUFO will automatically sync with your browser and check the refresh rate of the monitor. The results are displayed in the middle of the screen.

It’s advised to close all other running programs and browser tabs while running the test to minimize any interference. In case the internet is choppy, the tool will display a warning at the bottom. Wait until it shows a green “Ready” to confirm the results.

TestUFO also offers other tools to test additional parameters of your monitor. For example, you can check your display for frame skipping, which comes in handy if you are overclocking your monitor.

Simple and minimalistic, this test does what it says: display the refresh rate of your monitor in Hertz (Hz). The test is notable for how quickly it works, giving you a result in mere seconds. This is much faster than most similar tools in the market.

It’s an improved version of an older tool called Vsync Tester (which might still be better for older devices). Its accuracy is unmatched, giving you the refresh rate in six decimal points, which is leagues ahead of the competition.

This tool is especially useful when comparing multiple displays, as most screens will show roughly the same values. The additional precision allows for a better comparison to be made.

This nifty little tool can test your display and quickly determine its refresh rate. While it shows results only to a single decimal point, the value is determined in seconds.

Display Test works on most browsers including Apple WebKit and Mozilla’s Gecko-based offerings, apart from Chrome, of course. It also has a better UI than most such tools, making it easy to use and understand.

We have listed this on number four, but this is probably the most comprehensive tool on the list. The Eizo Monitor Test doesn’t just test the refresh rate of your monitor, but everything about it.

Defective pixels, color distances, sharpness, viewing angle – this tool tests your monitor on all important technical aspects. It is also fully customizable, allowing you to choose which of the tests to run, so you can just use the refresh rate test if in a hurry.

These features make the Eizo monitor test a very helpful asset in diagnosing monitor issues. You should use the site to check your monitor from time to time to ensure that it’s functioning properly.

This tool works a bit differently. Instead of just displaying the numeric value of your refresh rate, it actually shows different refresh rates in action.

When you open Frames-Per-Second, you will be greeted with a repeating animation of two spherical objects bouncing back and forth over a moving background. Each of these images runs on a different fps, demonstrating how different frame rates appear in action.

You can modify these numbers to your liking, setting each animation at any fps you want. Things like Motion Blur can also be set to get an accurate gauge of how these frame rates look in comparison.

If you’re looking for the best precision and accuracy possible, DisplayHZ is the tool you are looking for. It provides results up to six decimal places and works quickly.

For a more holistic look at your monitor, you must use the Eizo monitor test. It will help in testing your device for all sorts of visual issues, making sure it is working properly.

Whether you’re checking the specs of an old monitor or thinking of upgrading to a new one, the refresh rate is one of the core features to consider. And with these tools, you can determine where your display stands.

As of Test Bench 1.2, there are two separate test boxes that we evaluate, and they are tested at the same time. The first is the Refresh Rate box to determine the display"s native and max refresh rate depending on its connection type and the signal sent. We test it with a test PC using an NVIDIA graphics card, usually an RTX 3000 Series card, and the test is done at the monitor"s native resolution.

As of Test Bench 1.2, there are two separate test boxes that we evaluate, and they are tested at the same time. The first is the Refresh Rate box to determine the display"s native and max refresh rate depending on its connection type and the signal sent. We test it with a test PC using an NVIDIA graphics card, usually an RTX 3000 Series card, and the test is done at the monitor"s native resolution.

The max refresh rate denotes the maximum frequency the monitor can refresh the image, as supported by the manufacturer. It includes the factory overclock that comes with many gaming monitors. Note that this only looks at officially supported overclock modes; it may be possible to overclock most monitors through overclocking tools and custom resolutions, but we don"t check for this.

We check this max refresh rate with both DisplayPort and HDMI connections, and this is done by sending an 8-bit color depth signal. For many monitors, you can only achieve the max refresh rate over a DisplayPort connection because DP 1.2 and 1.4 connections have higher bandwidth than the older HDMI 2.0 bandwidth, which is still found on many monitors.

We repeat the same tests to determine the max refresh rate, but by sending a 10-bit signal. It"s important for HDR games as HDR requires 10-bit color depth, so with this test, you can see the max refresh rate at which you can play. Due to HDMI 2.0"s bandwidth limitations, many monitors have a limited refresh rate over HDMI, and once again, you"ll likely need to use the DisplayPort connection to use the monitor to its full potential.

The second test we do is to determine the VRR formats and the range at which it works. We use PCs with RTX 3000 Series and RX6600 XT graphics cards to test the G-SYNC and FreeSync support, and we also use NVIDIA"s G-SYNC Pendulum Demo and check games to make sure VRR is working properly across the refresh rate range of the display. The Pendulum Demo can be used to test any VRR format supported by the PC and monitor. We look to see if there"s any screen tearing or other unusual artifacts in the demo.

Unfortunately, we don"t officially test for HDMI Forum VRR support like with TVs, but you"ll know if the monitor supports HDMI Forum VRR if the VRR feature works with the PS5 in the PS5 Compatibility Box.

We check for FreeSync compatibility with a PC with an AMD Radeon graphics card, usually RX6600 XT. This test is important if you"re planning on using the variable refresh rate feature with an AMD Radeon graphics card or with an Xbox One S/X or Xbox Series S|X. There are three possible results for this test:

Yes:The VRR works, and most monitors that work with AMD graphics cards fall under this result. As long as the manufacturer advertises FreeSync support, or if AMD has it on their list of supported monitors, then the monitor gets a "Yes". We don"t specify whether it"s FreeSync, FreeSync Premium, or FreeSync Premium Pro certified, we just know that it works.

Compatible (Tested):If the VRR support works with an AMD graphics card, but it isn"t advertised on the manufacturer or AMD"s websites, then it"s considered "Compatible". Not many monitors are like this now, and as long as the VRR works, there isn"t a difference in performance versus a monitor that has the certification from AMD.

Like the above test, we check for G-SYNC compatibility with a PC that has an RTX 3000 Series graphics card. This test is only important if you"re planning on using the monitor with an NVIDIA graphics card. Unlike with FreeSync support, the different results can have an impact on the monitor"s performance with an NVIDIA graphics card, and NVIDIA is tighter with their certifications.

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 any 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 really isn"t a difference in performance between the two sets of monitors, and there could be different reasons why it"s not certified by NVIDIA, including NVIDIA simply not testing it. As long as the VRR support works over its entire refresh rate range, that means 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.

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. Like with FreeSync, 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, like with the two previous ones, we make sure 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 also check with a few games to make sure it"s working with real content as well.

This test represents the maximum frequency at which the variable refresh rate feature can be enabled and work properly. We test this using the NVIDIA Pendulum Demo, and most of the time the "VRR Maximum" is just the same result as the "Max Refresh Rate", but there are some cases where the overclock causes some issues with the VRR.

Our VRR Minimum test checks for the minimum frame rate at which the VRR feature is still working properly. Like the previous test, we check this using the NVIDIA Pendulum Demo, gradually reducing the frame rate until the screen starts tearing. If a monitor supports both FreeSync and G-SYNC, we also check the range of each. If there"s any difference between them, we put the widest range as the result and note the difference in the text.

Because we test for the effective frame rate and not the actual refresh rate of the display, our minimum refresh rate is frequently lower than the minimum reported by the manufacturer. It"s because many monitors support a feature known as Low Framerate Compensation (LFC). If the framerate of the source drops below the minimum refresh rate of the display, the graphics card automatically multiples frames to bring the framerate back within the refresh rate range of the display. Since we look at the effective VRR range, we don"t differentiate between monitors that use LFC and monitors that can reduce their actual refresh rate.

We repeat the tests above over both DisplayPort and HDMI connections and list which connections the VRR feature works on. Most of the time, the VRR works over both connections, but because the maximum refresh rate can be different over HDMI, we also include in the text if there are differences in the range. Also, we"ll include in the text which connections you need for the G-SYNC or FreeSync VRR to work, as many G-SYNC compatible displays only work over DisplayPort connections, but higher-end monitors with HDMI 2.1 bandwidth now support G-SYNC over both connections.

While refresh rate has the biggest impact on the clarity and fluidity of motion on screens, you also need a good response time to have smooth motion handling. We measure this as part of our motion blur test, and it refers to the time it takes for the display"s pixels to switch from one state to another across a variety of transitions (for example, from showing black to showing white).

The relation between them is found when looking at what we call frame time. The frame time refers to the length of time a frame is shown on screen. For example, a 120Hz monitor has 120 cycles per second, so every frame appears every 8.33 ms. If your screen"s average pixel response time is higher than this, it can cause blurriness since the pixels rarely have time to complete their transition before switching to displaying the next frame. Because of this, it"s important to consider our entire motion section and not only the refresh rate to evaluate the motion capabilities of a monitor.

The refresh rate also has an impact on the input lag of a monitor. There"s more of a direct relation here than with the response time, as the lower refresh rate helps result in lower input lag. A 60Hz monitor results in a frame time of 16.67 ms, and because we measure the input lag in the middle of the screen, the minimum input lag for a 60Hz display is 8.33 ms (it takes half the frame time to refresh in the middle of the screen). However, a 360Hz monitor has a frame time of 2.78 ms, which a minimum input lag of 1.39 ms, so you get a much more responsive feel with a higher refresh rate monitor.

There isn"t much to do to enable the maximum refresh rate of your monitor. It"s mostly a plug-and-play affair and doesn"t require much tinkering to get working right, as long as your graphics card can take advantage of the maximum refresh rate.

Change the refresh rate setting on your computer. You can do this either through your graphics card"s driver settings or in Windows through the display adapter properties panel found in your display settings.

Some high-end gaming monitors have an Overclock feature that allows you to boost your screen"s refresh rate beyond its standard rating. You can access this in the monitor"s on-screen display menu. You will need to change the refresh rate in your operating system to match the overclock afterward.

G-SYNC and FreeSync also have to be enabled through your graphics card"s driver settings. These can easily be accessed by right-clicking on your desktop.

Some games and other applications that execute in full-screen mode ignore the system setting for refresh rate and might require you to enable your monitor"s maximum refresh rate through their internal settings.

The refresh rate is the number of times the monitor"s screen refreshes every second. Higher frequencies produce smoother and clearer motion and enable more responsive interaction. It"s most important for video games, but it offers an improvement for almost every type of usage as long as the content or device supplies a matching frame rate to the refresh rate of the display. We test to see the maximum refresh rate the monitor can function at its native resolution, and we also check to see which variable refresh rate formats it supports, as well as the range at which it works.

It’s natural for anyone shopping desktop monitors to be swayed by size, shape, resolution and color quality. But depending on your business needs, you may also want to consider a less flashy feature: the monitor’s refresh rate.

Refresh rate is the frequency at which the screen updates with new images each second, measured in hertz (cycles per second). The content may look steady on the display, but what the viewer can’t see is how fast the content is changing — up to 360 times a second. The higher the refresh rate, the smoother the visual quality.

Super high monitor refresh rates aren’t all that important for office workers focused on lighter computing like word processing, spreadsheets and emails. But in more visual professions like creative production and game development, a high refresh rate for monitors is invaluable.

The standard refresh rate for desktop monitors is 60Hz. But in recent years, more specialized, high-performing monitors have been developed that support 120Hz, 144Hz and even 240Hz refresh rates, which ensure ultra-smooth content viewing, even for the most demanding visual processing needs.

Just buying a high refresh rate monitor doesn’t mean the display quality will magically improve. The monitor’s refresh rate reflects the maximum rate at which the display can change the visuals. What happens on the screen depends on the frame rate of the output — the number of video frames that are sent to the display each second.

The majority of Hollywood movies, for example, are shot and produced at 24 frames per second (fps), so a 60Hz monitor will easily offer smooth playback. But having a 120Hz monitor (or even faster) won’t provide any visible benefit to playback quality.

A 120Hz monitor has obvious benefits, though, for modern gaming platforms that animate at 100 fps or higher. A high refresh rate helps the screen keep pace with the high-twitch inputs of players and translate them into super smooth actions on screen.

When refresh rate and frame rate are mismatched, it can result in something called screen tearing. If the computer’s graphic card is pushing out more frames than the monitor’s refresh rate can handle at a given moment, users may see two half-frames on the screen at once, bisected horizontally and slightly misaligned. In short, it doesn’t look good. Games are usually configured to automatically match the PC’s graphics capabilities to avoid tearing, but running high-action visuals more slowly than intended makes for a compromised viewing and playing experience.

Response time — the time it takes for a pixel to change color — also plays a role in refresh rate. A monitor can only refresh as quickly as the LCD display can make those rapid-fire color shifts.

Particularly for fast-paced visuals, higher refresh rates and faster pixel response times reduce ghosted visuals, and ideally eliminate them. With slower tech, a high-pace action sequence may come with trailing images that result in softer, even blurry on-screen visuals.

The appeal of high refresh rates is obvious for at-home gamers looking for a responsive, hyperrealistic playing experience. And this leisure use is part of a vast global industry. SuperData reported that the video gaming industry generated roughly $140 billion in 2020, up 12 percent from $120 billion in 2019. Statista estimates there are now more than 3 billion gamers worldwide.

The nascent esports industry is already worth more than $1 billion, and companies of all sizes and sorts — including casino operators — are scrambling to establish esports gaming zones and arenas for fans to watch and play popular games like Overwatch.

In the U.S. alone, the video game industry employs 220,000 people across all 50 states, according to the Entertainment Software Association. That’s a lot of game developers, graphic artists and playtesters working in front of monitors, most of them in need of optimal visual quality and speed at their workstations. While 60Hz refresh rates may work fine for people in finance and human resources — and even the clerical side of gaming companies — people on the visual and testing side need at least 120Hz to do their jobs well.

And it’s not just gaming. While the film industry has long produced movies at 24 fps, that frame rate is a relic of times when there were different technical restraints on cameras and projection, so a faster frame rate required more expensive film. The 24 fps standard has stuck around largely because that’s what the public is used to. Today, filmmakers are increasingly pushing frame rates as high as 120 fps.

High-performance monitors with high refresh rates come with obvious visual improvements, but monitor upgrades in general bring a broader range of business benefits.

Higher-quality monitors — notably those with Quantum Dot enhancement film — offer an immense color palette and extreme color accuracy. Users don’t just see red; they see the exact shade of red the artist intended. High dynamic range (HDR), featured on high-resolution monitors from Samsung, clarifies every element of every scene — even the brightest highlights and darkest shadows — so the smallest details are fully discernible and distinct.

Premium monitors also come with built-in (adjustable) technologies that can reduce eye strain. Manufacturers, led by Samsung, have increasingly introduced curved widescreen monitors that equalize the focal distance of every part of the screen. The left and right edges are the same distance from the viewer’s eyes as the middle of the screen, reducing eye strain, as viewers don’t have to adjust their eyes as they scan the display.

High refresh rate monitors with high response times also tend to come with other premium features, such as full support for USB-C connections. With a single cable, the user can connect their PC to a monitor that functions as a USB hub for peripheral devices. This negates the need for expensive and often clunky docking stations, and can significantly reduce the number of cables at each workstation. In addition to tidier, streamlined workspaces, this also reduces the demand for IT support. With fewer connectors and devices, you tend to get fewer problems.

Around the workplace, anyone in a visually creative role will see immediate benefits from a higher refresh rate. And while those in non-visual roles probably won’t see any difference, the key may be futureproofing.

When IT and information systems (IS) teams plan capital purchases, they need to look several years ahead for potential technical requirements down the road. While high-refresh monitors may have a defined user community right now, it’s likely more use cases and worker needs will develop. Monitors with low refresh rates can’t get better, but higher-refresh monitors can serve your display needs both now and in the future.

The refresh rate (or "vertical refresh rate", "vertical scan rate", terminology originating with the cathode ray tubes) is the number of times per second that a raster-based display device displays a new image. This is independent from frame rate, which describes how many images are stored or generated every second by the device driving the display.

On cathode ray tube (CRT) displays, higher refresh rates produce less flickering, thereby reducing eye strain. In other technologies such as liquid-crystal displays, the refresh rate affects only how often the image can potentially be updated.

Non-raster displays may not have a characteristic refresh rate. Vector displays, for instance, do not trace the entire screen, only the actual lines comprising the displayed image, so refresh speed may differ by the size and complexity of the image data.

Raster-scan CRTs by their nature must refresh the screen, since their phosphors will fade and the image will disappear quickly unless refreshed regularly.

In a CRT, the vertical scan rate is the number of times per second that the electron beam returns to the upper left corner of the screen to begin drawing a new frame.vertical blanking signal generated by the video controller, and is partially limited by the monitor"s maximum horizontal scan rate.

The refresh rate can be calculated from the horizontal scan rate by dividing the scanning frequency by the number of horizontal lines, plus some amount of time to allow for the beam to return to the top. By convention, this is a 1.05x multiplier.1280 × 1024 results in a refresh rate of 96,000 ÷ (1024 × 1.05) ≈ 89 Hz (rounded down).

CRT refresh rates have historically been an important factor in videogame programming. In early videogame systems, the only time available for computation was during the vertical blanking interval, during which the beam is returning to the top corner of the screen and no image is being drawn.screen tearing.

Unlike CRTs, where the image will fade unless refreshed, the pixels of liquid-crystal displays retain their state for as long as power is provided, and consequently there is no intrinsic flicker regardless of refresh rate. However, refresh rate still determines the highest frame rate that can be displayed, and despite there being no actual blanking of the screen, the vertical blanking interval is still a period in each refresh cycle when the screen is not being updated, during which the image data in the host system"s frame buffer can be updated.

On smaller CRT monitors (up to about 15 in or 38 cm), few people notice any discomfort between 60–72 Hz. On larger CRT monitors (17 in or 43 cm or larger), most people experience mild discomfort unless the refresh is set to 72 Hz or higher. A rate of 100 Hz is comfortable at almost any size. However, this does not apply to LCD monitors. The closest equivalent to a refresh rate on an LCD monitor is its frame rate, which is often locked at 60 fps. But this is rarely a problem, because the only part of an LCD monitor that could produce CRT-like flicker—its backlight—typically operates at around a minimum of 200 Hz.

Different operating systems set the default refresh rate differently. Microsoft Windows 95 and Windows 98 (First and Second Editions) set the refresh rate to the highest rate that they believe the display supports. Windows NT-based operating systems, such as Windows 2000 and its descendants Windows XP, Windows Vista and Windows 7, set the default refresh rate to a conservative rate, usually 60 Hz. Some fullscreen applications, including many games, now allow the user to reconfigure the refresh rate before entering fullscreen mode, but most default to a conservative resolution and refresh rate and let you increase the settings in the options.

Old monitors could be damaged if a user set the video card to a refresh rate higher than the highest rate supported by the monitor. Some models of monitors display a notice that the video signal uses an unsupported refresh rate.

Some LCDs support adapting their refresh rate to the current frame rate delivered by the graphics card. Two technologies that allow this are FreeSync and G-Sync.

When LCD shutter glasses are used for stereo 3D displays, the effective refresh rate is halved, because each eye needs a separate picture. For this reason, it is usually recommended to use a display capable of at least 120 Hz, because divided in half this rate is again 60 Hz. Higher refresh rates result in greater image stability, for example 72 Hz non-stereo is 144 Hz stereo, and 90 Hz non-stereo is 180 Hz stereo. Most low-end computer graphics cards and monitors cannot handle these high refresh rates, especially at higher resolutions.

For LCD monitors the pixel brightness changes are much slower than CRT or plasma phosphors. Typically LCD pixel brightness changes are faster when voltage is applied than when voltage is removed, resulting in an asymmetric pixel response time. With 3D shutter glasses this can result in a blurry smearing of the display and poor depth perception, due to the previous image frame not fading to black fast enough as the next frame is drawn.

This gif animation shows a rudimentary comparison of how motion varies with 4Hz, 12Hz, and 24Hz refresh rates. Entire sequence has a frame rate of 24Hz.

The development of televisions in the 1930s was determined by a number of technical limitations. The AC power line frequency was used for the vertical refresh rate for two reasons. The first reason was that the television"s vacuum tube was susceptible to interference from the unit"s power supply, including residual ripple. This could cause drifting horizontal bars (hum bars). Using the same frequency reduced this, and made interference static on the screen and therefore less obtrusive. The second reason was that television studios would use AC lamps, filming at a different frequency would cause strobing.NTSC color coding) and 50 Hz System B/G (almost always used with PAL or SECAM color coding). This accident of chance gave European sets higher resolution, in exchange for lower frame-rates. Compare System M (704 × 480 at 30i) and System B/G (704 × 576 at 25i). However, the lower refresh rate of 50 Hz introduces more flicker, so sets that use digital technology to double the refresh rate to 100 Hz are now very popular. (see Broadcast television systems)

Another difference between 50 Hz and 60 Hz standards is the way motion pictures (film sources as opposed to video camera sources) are transferred or presented. 35 mm film is typically shot at 24 frames per second (fps). For PAL 50 Hz this allows film sources to be easily transferred by accelerating the film by 4%. The resulting picture is therefore smooth, however, there is a small shift in the pitch of the audio. NTSC sets display both 24 fps and 25 fps material without any speed shifting by using a technique called 3:2 pulldown, but at the expense of introducing unsmooth playback in the form of telecine judder.

Similar to some computer monitors and some DVDs, analog television systems use interlace, which decreases the apparent flicker by painting first the odd lines and then the even lines (these are known as fields). This doubles the refresh rate, compared to a progressive scan image at the same frame rate. This works perfectly for video cameras, where each field results from a separate exposure – the effective frame rate doubles, there are now 50 rather than 25 exposures per second. The dynamics of a CRT are ideally suited to this approach, fast scenes will benefit from the 50 Hz refresh, the earlier field will have largely decayed away when the new field is written, and static images will benefit from improved resolution as both fields will be integrated by the eye. Modern CRT-based televisions may be made flicker-free in the form of 100 Hz technology.

Many high-end LCD televisions now have a 120 or 240 Hz (current and former NTSC countries) or 100 or 200 Hz (PAL/SECAM countries) refresh rate. The rate of 120 was chosen as the least common multiple of 24 fps (cinema) and 30 fps (NTSC TV), and allows for less distortion when movies are viewed due to the elimination of telecine (3:2 pulldown). For PAL at 25 fps, 100 or 200 Hz is used as a fractional compromise of the least common multiple of 600 (24 × 25). These higher refresh rates are most effective from a 24p-source video output (e.g. Blu-ray Disc), and/or scenes of fast motion.

As movies are usually filmed at a rate of 24 frames per second, while television sets operate at different rates, some conversion is necessary. Different techniques exist to give the viewer an optimal experience.

The combination of content production, playback device, and display device processing may also give artifacts that are unnecessary. A display device producing a fixed 60 fps rate cannot display a 24 fps movie at an even, judder-free rate. Usually, a 3:2 pulldown is used, giving a slight uneven movement.

While common multisync CRT computer monitors have been capable of running at even multiples of 24 Hz since the early 1990s, recent "120 Hz" LCDs have been produced for the purpose of having smoother, more fluid motion, depending upon the source material, and any subsequent processing done to the signal. In the case of material shot on video, improvements in smoothness just from having a higher refresh rate may be barely noticeable.

In the case of filmed material, as 120 is an even multiple of 24, it is possible to present a 24 fps sequence without judder on a well-designed 120 Hz display (i.e., so-called 5-5 pulldown). If the 120 Hz rate is produced by frame-doubling a 60 fps 3:2 pulldown signal, the uneven motion could still be visible (i.e., so-called 6-4 pulldown).

Additionally, material may be displayed with synthetically created smoothness with the addition of motion interpolation abilities to the display, which has an even larger effect on filmed material.

The refresh rate of a display is the number of times per second that the image refreshes on the screen. For example, a 60Hz display will update the screen 60 times per second.

Overall, the refresh rate determines how smoothly motion appears on your screen. For example, if you’re playing a game that has a lot of fast-moving action, a higher refresh rate can help improve your overall gaming experience to keep up with the action. A higher refresh can also help you get a better experience with smoother motion when you"re browsing the web or using a digital pen to write or draw.

A higher refresh rate can also reduce battery life because it uses more power. So if you"re using a laptop or tablet and want to save some battery, you could lower the refresh rate. However, that might also reduce the overall experience when you"re using your device.

Note:You might see the word “dynamic” next to some refresh rates that are listed. Dynamic refresh rates will increase the refresh rate automatically when you’re inking and scrolling, and then lower it when you’re not doing these types of things. This helps to save battery and provide a smoother experience.

The refresh rate of a monitor or TV is the maximum number of times the image on the screen can be drawn, or refreshed, per second. The refresh rate is measured in hertz.

Instead, the image is "redrawn" over and over on the screen so quickly (anywhere from 60, 75, or 85 to 100 times or more per second) that the human eye perceives it as a static image, or a smooth video, etc.

This means that the difference between a 60 Hz and 120 Hz monitor, for example, is that the 120 Hz one can create the image twice as fast as the 60 Hz monitor.

An electron gun sits behind the glass of the monitor and shoots light to produce an image. The gun starts at the very top left corner of the screen and then quickly fills it with the image, line by line across the face and then downward until it reaches the bottom, after which the electron gun moves back to the top left and starts the whole process over again.

While the electron gun is in one place, another portion of the screen may be blank as it waits for the new image. However, due to how fast the screen is refreshed with the light of the new image, you don"t see this.

If the refresh rate of a monitor is set too low, you may be able to notice the "redrawing" of the image, which we perceive as a flicker. Monitor flickering is unpleasant to look at and can quickly lead to eye strain and headaches.

The refresh rate setting can be changed to reduce this flickering effect. See our How to Change a Monitor"s Refresh Rate Setting in Windows guide for instructions on doing this in all versions of Windows.

All LCD monitors support a refresh rate that is typically over the threshold that normally causes flicker (usually 60 Hz) and they don"t go blank between refreshes as CRT monitors do.

The highest possible refresh rate isn"t necessarily better. Setting the refresh rate over 120 Hz, which some video cards support, may have an adverse effect on your eyes as well. Keeping a monitor"s refresh rate set at 60 Hz to 90 Hz is best for most.

Attempting to adjust a CRT monitor"s refresh rate to one that"s higher than the specifications of the monitor may result in an "Out of Frequency" error and leave you with a blank screen. Try starting Windows in Safe Mode and then changing the monitor refresh rate setting to something more appropriate.

Three factors determine the maximum refresh rate: The monitor"s resolution (lower resolutions typically support higher refresh rates), the video card"s maximum refresh rate, and the monitor"s maximum refresh rate.

When you"re looking to buy a new monitor, there are many factors to consider, including size, resolution, and aspect ratio. Another important aspect you might hear about is the refresh rate.

The refresh rate of a monitor (or other display) refers to the maximum number of times per second that the image displayed on the screen will be updated. This is measured in hertz (Hz).

A higher refresh rate means more information reaches your eyes in the same amount of time, leading to smoother-looking motion. Remember that video is technically just a series of images being shown very quickly to have the effect of motion.

Most standards monitors are 60Hz. However, you can also buy monitors, usually meant for gaming, that boast higher refresh rates. Common refresh rates for higher-tier monitors are 144Hz or even 240Hz.

These numbers make it easy to compare one monitor to another. A 120Hz monitor can display twice as many images in a second as a 60Hz monitor, for example.

Because monitors with higher refresh rates are capable of displaying smoother motion, you might think that buying one will instantly improve the look of everything on your PC. But this isn"t necessarily the case.

Remember that the refresh rate is the maximum rate at which your monitor can update the displayed image. But whether a program actually sends output to your monitor that fast depends on its frame rate. The frame rate measures the number of video frames sent to your display per second.

To take advantage of a display with a higher refresh rate, your computer has to send data to the display much faster. Most software, such as productivity apps or video playback utilities, won"t be affected by an ultra-high refresh rate.

Movies are shown at 24 frames per second (FPS), and YouTube currently caps out at 60FPS; even basic 60Hz monitors can handle these without issue. A higher refresh rate thus won"t make most videos look any better. This also applies to most productivity apps. For example, Microsoft Word won"t have any noticeable difference at 144FPS compared to using it at 60FPS.

As a result, high refresh rates are really only important when playing video games. When playing a game, your graphics card generates the visual data and sends it to your monitor. Thus, if you have a powerful enough graphics card, it can send data to the screen more quickly.

As the frame rate your graphics card sends and the refresh rate of your monitor are often different, a common PC gaming problem people run into is screen tearing. This can happen, among other causes, when your graphics card sends out frames at a higher rate than your monitor can handle.

If you try to play a game at a high frame rate on a low refresh rate monitor, you"ll run into this issue. You"ll see multiple frames on your screen at the same time that aren"t lined up correctly, leading to the "torn" effect.

To avoid this, games are usually capped at your monitor"s refresh rate by default. So if you have a 60Hz refresh rate monitor, your games should not run at much more than 60FPS.

There are also more advanced solutions to this problem, such as G-Sync, VSync, and FreeSync. See our explanation of common video game graphics settings for more info.

The main group of people who benefit from a high refresh rate monitor are competitive gamers. For professional players of first-person shooters like Counter-Strike: Global Offensive or Overwatch, a higher refresh rate is vital for optimal gameplay.

When your monitor displays more frames per second, you also see visual information that you would have completely missed on a lower-hertz display. This makes it easier to track fast-paced action.

It"s difficult to show a clear example of frame rates above 60FPS if your monitor can"t display them. If you"re curious, have a look at the below video to see the same action in various frame rates, slowed down so it"s easier to tell the difference.

Some people say higher refresh rates make it easier to aim, as targets move more smoothly. But this varies by individual and can change based on how good your eyesight is.

Part of this is due to blurring. When our eyes see a series of frames, our brains fill in the changes from one frame to the next, making the frames look like continuous video instead of the series of still images they actually are. But this filling-in process results in blurring. If there"s more information sent to our brains in the form of more frequent frames, movement looks sharper.

Another issue in high-level gaming is input lag, which is the delay between you making an input and the game recognizing that input. High refresh rate monitors can reduce input lag, because there is a shorter amount of time that passes between your input and the action happening on-screen.

This difference is tiny—in the order of milliseconds—but that can make a difference in competitive scenarios. For professionals and other serious players, every tiny advantage matters.

But what if this doesn"t describe you? If you"re a casual at-home gamer, or don"t play games at all, is a high refresh rate monitor worth the extra cost?

If you don"t play video games, then buying a monitor above 60Hz is likely not worth the cost for you. There are few applications outside of gaming where higher frame rates will make a noticeable difference. If you want to upgrade your monitor, you"re better off putting the money towards a display that"s larger, higher-resolution, or has better image quality.

For gamers, high refresh rate monitors are a noticeable upgrade, especially if you play fast-paced games like shooters. Going from 60FPS to 144HZ isn"t as major as jumping from 30FPs to 60FPS, but it does make a difference. If you only play slower-paced games like strategy titles, you may be perfectly happy at 60FPS.

60FPS is a decent standard—if your computer can"t hit that, you should prioritize upgrading your graphics card (and potentially other components like the CPU) first.

A 240Hz monitor that"s 24 inches wide at 1080p resolution would cost you a good bit of money. For around the same price, you could buy a larger 27-inch monitor at 1440p resolution with a still-impressive 144Hz refresh rate. Or if refresh rates don"t matter to you, you could buy a huge 34-inch monitor at 4K resolution and a standard 60Hz refresh rate instead.

Alternatively, you could buy a cheaper monitor and put the money you save towards a better graphics card. Remember that the highest refresh rate monitor in the world won"t make a difference if your graphics card can"t keep up. It"s better to have a high-end graphics card with a middle-range monitor than a top-of-the-line monitor and mediocre graphics card.

If you need a new monitor for general computing purposes, in most cases you"ll want a higher resolution so the picture looks sharper. This is beneficial when you"re watching movies or doing various productivity tasks. You may also consider buying a larger monitor so you can see more at once, or even buying two cheaper monitors so you can take advantage of dual displays.

When buying a monitor for serious PC gaming, a higher refresh rate is important. If possible, try to shop for monitors in-person where you can see the differences between refresh rates. While you can find comparisons online, you can"t really appreciate videos of 144FPS gameplay on a 60Hz monitor.

As we"ve seen, high refresh rates are really only important for serious gamers. Casual gamers can enjoy most titles at 60FPS, while general PC users don"t have much use at all for higher frame rates. They"ll usually be better off spending money on a bigger, higher-resolution monitor instead.

When comparing the performance of two custom gaming PCs, we often look at the frame rates each computer is capable of producing in a certain game at the same resolution and graphics quality. Frame rates are measured in FPS or Frames per Second. Most people know that higher FPS is better, but let’s clear up some common misconceptions with FPS and refresh rates.

First, what is a frame and what determines the frame rate? A frame is a single still image, which is then combined in a rapid slideshow with other still images, each one slightly different, to achieve the illusion of natural motion. The frame rate is how many of these images are displayed in one second. To produce, or render, a new frame your CPU and GPU work together to determine the actions of the AI, the physics, positions, and textures of the objects in the scene to produce an image. Then your GPU cuts this image into pixels at the resolution you set and sends this information to the display. The more powerful your CPU and GPU, the more frames they are able to generate per second.

Your monitor or display is where refresh rates come in. Refresh rate is measured in frequency (Hz) which is the number of times per second your monitor can redraw the screen. A refresh rate of 85Hz means that your display can redraw the entire screen 85 times in one second.

Does that mean that your frame rate is limited by your screen’s refresh rate? No; they are two separate things. Remember that FPS is how many frames your custom gaming PCs is producing or drawing, while the refresh rate is how many times the monitor is refreshing the image on the screen. The refresh rate (Hz) of your monitor does not affect the frame rate (FPS) your GPU will be outputting. However, if your FPS is higher than your refresh rate, your display will not be able to display all of the frames your computer is producing, so although the refresh rate doesn’t technically limit the frame rate, it does effectively set a cap.

It’s also important to remember that even if your gaming PC is capable of generating 90 FPS in your favorite game at your preferred settings, and even if your monitor supports 90Hz, 120Hz or more, you could still be capped by the lower refresh rate capabilities of the ports on your graphics card and display. Read our blog post on DisplayPort vs HDMI vs DVI vs VGA to learn about the pros, cons and limitations of the different types of connections. For example, some gaming monitors feature 120Hz refresh rates, but have HDMI 1.4 and DisplayPort 1.4. This means that you can only take advantage of the 120Hz refresh rate if your use DisplayPort; you’ll be stuck at 60Hz if you use HDMI.

Frame rate is typically used as a gaming benchmark for measuring the performance of hardware, drivers, games and APIs like Vulkan and DirectX. In this case the monitor’s refresh rate doesn’t matter because the frame rate is just used as a number to measure the gaming performance. A higher frame rate is better. However, when you’re actually playing a game, the display’s refresh rate does effectively limit the frame rate – if you have an 80hz display and your computer is capable of outputting 120 FPS, your screen will still only be able to show 80 different images per second.

To prevent screen tearing, you can enable a feature called Vertical Synchronization, or VSync. This tells your GPU to synchronize its actions with the display, which forces it to render and send a new frame when the monitor is ready to redraw the screen. This does limit your framerate exactly to the refresh rate. For example, if your refresh rate is 60Hz, VSync will cap your framerate to 60 FPS. If your GPU is capable of producing higher frame rates than the VSync cap you can take advantage of its leftover capacity to increase the resolution, draw distance, or other graphics quality settings. If your graphics card can’t outpace the refresh rate of your display then enabling VSync won’t help much. You may be able to lock your GPU into a lower frame rate, like 30 FPS, that would match up with your monitor. Common display refresh rates include 120hz, 60hz and 30hz, and there are all divisible by 30 so you won’t get screen tearing, but you may get stutter, as each frame will be on the screen for a couple of cycles.

If your monitor and graphics card both in your customer computer support NVIDIA G-SYNC, you’re in luck. With this technology, a special chip in the display communicates with the graphics card. This lets the monitor vary the refresh rate to match the frame rate of the NVIDIA GTX graphics card, up to the maximum refresh rate of the display. This means that the frames are displayed as soon as they are rendered by the GPU, eliminating screen tearing and reducing stutter for when the frame rate is both higher and lower than the refresh rate of the display. This makes it perfect for situations where the frame rate varies, which happens a lot when gaming. Today, you can even find G-SYNC technology in gaming laptops!

AMD has a similar solution called FreeSync. However, this doesn’t require a proprietary chip in the monitor. Instead, FreeSync relies on the DisplayPort’s Adaptive-Sync specification, which is a royalty-free industry standard. The difference between them is that in G-SYNC, the proprietary module in the monitor handles the work of communication between the devices. In FreeSync, the AMD Radeon driver, and the display firmware handle the communication. AMD has demonstrated that FreeSync can work over HDMI, but it requires custom drivers from AMD and the monitor’s manufacturer. Currently G-SYNC only works with DisplayPort, but that may change. Generally, FreeSync monitors are less expensive than their G-SYNC counterparts, but gamers generally prefer G-SYNC over FreeSync as the latter may cause ghosting, where old images leave behind artifacts. However, this may change as both technologies are relatively new.

When comparing 60 Hz vs 75 Hz refresh rates, the answer is quite clear: 75 Hz is better. A refresh rate measures how many times a screen can update in one second. Higher refresh rates are associated with better video quality, reduced eye strain, and even improved gaming experiences. And while 60 Hz has been the bare minimum for decades, a 75 Hz monitor offers an accessible upgrade.

Refresh rate measures how many times a display can update the image on the screen. Video is actually a series of still images that change so quickly that they give the illusion of movement. The faster these images change, the smoother the video appears to be.

A screen’s refresh rate is measured in hertz (Hz), which is a unit of how many times something occurs in one second. Therefore, a refresh rate of 1 Hz shows a new image on the screen every second. A refresh rate of 75 Hz shows 75 separate images in a single second.

Generally speaking, a higher refresh rate results in smoother and more lifelike video so long as the frames per second match. (Ever wonder how many images per second the eye can process?It turns out it’s up to 500 Hz.)

Measured in frames-per-second (fps), frame rate also describes how many images get displayed on the screen each second. The difference lies in the source: refresh rate is determined by the display while frame rate is determined by the computer’s processors.

To fully take advantage of a monitor’s high refresh rate, it’s important that the computer’s central processing unit (CPU) and graphic processing unit (GPU) are able to produce enough frames per second. And on the other side, a high-performance graphics card would only go to waste if paired with a monitor with a slower refresh rate.

Sometimes more is just more. When it comes to refresh rates, a higher rate results in smoother video, less strain on the eyes, and even improved performance in competitive gaming. Even if that jump is a modest increase from 60 Hz to 75 Hz, there is a noticeable improvement in media quality.

So much of modern work deals with viewing and processing data. A smoother display makes a huge difference both in eye health and quickly understanding what’s on screen. A faster refresh rate makes it a much nicer work experience by reducing motion blur in text, graphics, data, and even your cursor.

Higher refresh rates result in smoother, more realistic on-screen media. More images per second can also significantly reduce motion blur, which can make a huge difference in video quality and gaming experiences.

Clearer and more natural motion on screen can go a long way towards better eye health. In fact, at lower refresh rates you may even start to notice aflicker, which can cause a wide range of vision problems and challenges.

A big part of effective ergonomics – for work and for play – is a high-quality display. A higher refresh rate on your monitor goes a long way towards protecting your eyes. Even a small difference like 60 Hz vs 75 Hz can make a huge difference over time.

Though there aremonitors specializing in gaming performance, it’s not always possible to get a high-end monitor just for entertainment. However, raising the bar by just 15 Hz can make a world of difference in not only game enjoyment but also performance.

Together these three factors can make games way more fun to play and even improve accuracy in high-paced games. But unless it’s a dedicated gaming rig,even hardcore gamers feel high-performance monitors aren’t strictly necessary for anything but games.

When it comes to monitor refresh rates, bigger is definitely better. However, 60 Hz represents a bare minimum while anything over 120 Hz is more appropriate to more demanding users. More modest screens with a 75 Hz refresh rate offer a middle ground.
