lcd panel refresh rate quotation

Monitors already do report their maximum refresh rate to your PC. Your computer then generally sends new frames at this maximum refresh rate, whether new data is available or not.

As for your variable framerate idea, this is another can of worms. The entire display chain, from applications to the operating system to the graphics card through the monitor are built on the concept that updates happen at a fixed, pre-defined interval. Changing this to a variable interval would require that we throw all of that out. Furthermore, how do you decide what framerate to use at any given moment? Suppose your monitor can update at 100Hz maximum, and you open a 60fps video in a window. Does that then force everything else to update at the 60fps refresh rate even if it wants to update the monitor at 100Hz or 90Hz? If you"re updating a portion of the screen at 60fps, then you no longer have any evenly-divisible time slices in which to do your 100Hz equivalent updates.

A much better solution is to just embrace the ubiquitous fixed-framerate system we have now and increase the refresh rate of our monitors to 120Hz or more. This maintains backwards compatibility for older monitors, but gives us small enough time steps that we can display any effective framerate we want. 120Hz is an even multiple of 24fps, 30fps, and 60fps and it"s fast enough that your eyes would never notice anything was amiss on other frame rates.

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.

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)

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).

CRT monitor must have a precise refresh frequency, due to its nature, it constantly redraws the picture. But since VGA that frequency is generated by the video card!

I always lived in 50Hz world and never encountered 50Hz computer monitors, so I"ve never seen a PC CRT monitor that actually syncs to the line frequency. Probably in the past (EGA and earlier) they were like this, but monitors don"t follow the line frequency for a quite long time and use Vsync signal from VGA to refresh instead.

In 1995 I"ve had a 14" CRT SVGA monitor that was able to sync at 1024x768 37.5Hz interlaced, which is half 75Hz and it was obviously generated by the VGA card clock. Other monitor I had around 2000 was 17", it was able to do 1024x768 at 85Hz (and that was extremely common); also it might do 1152x832 at 75Hz. Nothing like 60Hz, it never had such a recommendation. Since higher refresh rate lowered perceived flicker and eye fatigue, everybody wanted to have as much freq as possible. When LCD was introduced, it did not flicker at all. So was enough 60Hz (for the VGA signal, since there was no physical redraw at the panel) for it to be not eye-heavy. Everybody went 60Hz back, probably because the circuitry is cheaper when the frequency is lower, also the screen resolutions increased and there was always a tradeoff, if you want higher resolution, you can only achieve that at lower frequency.

Also, if you check the powering tract of the modern monitors, it is always switching power supply first, and the first thing SMPS does to the input voltage is to rectify it, then generate much higher frequency, to use smaller transformers. Then it transforms and rectifies it again. So there is nothing left from the input frequency.

You can change the refresh rate on your monitor through your display settings, though it may be limited by the monitor, graphics card, and screen resolution.

Your display"s refresh rate is a measure of how frequently the on-screen image is updated. Refresh rate is measured in hertz (Hz), which indicates the number of times per second something occurs. So a 60Hz display is one that has a refresh rate of 60 times per second.

Most people don"t need to worry much about refresh rate, especially when using a computer for ordinary productivity applications. That"s because computer displays typically have a refresh rate of 60Hz — that"s the default for many monitors — and that value is perfectly adequate almost all the time. It"s fast enough that there"s no obvious blurring or "image tearing" when there"s on-screen motion. Below this value — 30 Hz, for example — you might see some stuttering or jitteriness when things are moving on the screen.

Higher refresh rates are of interest to gamers, though. Because many video games rely on fast-moving visuals, many computer displays are optimized for gaming with very high refresh rates — 144Hz, 240Hz, and even 360Hz. For gaming, the higher the refresh rate the better.

There"s also a relationship between screen resolution and refresh rate. Because a computer only has so much bandwidth for the display, you might find that at higher resolutions, your display can"t run at its maximum refresh rate. If you are adjusting these settings, you might need to make a choice between, for example, an HD (1920x1080) display at 144Hz or a 4K (3840x2160) resolution at 60Hz.

Depending on your monitor or laptop display, you might be able to adjust the refresh rate. Some displays aren"t running at their highest refresh rate by default, for example, and it"s adjustable in the system settings. If you try to increase the refresh rate but it won"t go as high as you think the monitor is designed to go, you might need to lower the resolution to make a higher value become available.How to change the refresh rate on your PC monitor

The focus of this study is a description of features and artifacts of the LCD technology which are supposed to be relevant for psychophysical and neuroscientific experiments in general. A wide range of different monitor technologies and determinants of the temporal signal are compared. Three recent studies [30]–[32] approach the topic from the opposite side by focussing on well defined psychophysical requirements which they relate to only a few aspects on one or two LCD panels. In the following, we will briefly review these works and compare their approaches and results to the present study.

Kihara and colleagues [30] compare the performance in three psychophysical experiments which were performed on one LCD and two CRT devices, respectively. They statistically analyze the experimental results, fail to find significant differences for most of the conditions, and conclude that the three displays elicited similar performance profiles.

Wang and Nikolić [31] compared one CRT monitor and two different LCD panels, an old and a new model, with respect to both their spatial and temporal properties. The authors report that for the new LCD monitor the level of accuracy of timing and intensity was comparable, if not better to the benchmark CRT monitor, while the old LCD panel had a number of issues with respect to accuracy.

The study by Lagroix and colleagues [32] also analyses temporal properties. The authors investigate psychophysical estimates of visible persistence of stimuli immediately after their assumed disappearance on the display device. In their experiments, observers performed forced choice tasks on these stimuli, where a shutter controlled that the stimulus could not be seen during the period when it was (intendedly) displayed. They compared performance using a CRT and an LCD monitor. While there was considerable visible persistence on the CRT for white stimuli on black background, the authors did not find any perceptual persistence on the LCD panel.

Our study, however, demonstrates a number of artifacts due to improper DCC with some substantial effects on the luminance transition signal, such as luminance stepping or substantial overshoots. It remains important future work to study these artifacts with experimental paradigms as developed by Lagroix and colleagues, as it is likely that some of the artifacts presented in this work have considerable impacts on visual persistence.

Generic monitor displays normally have a flicker-rate of about 200-times per second, which is unnoticeable to the naked eye, but can cause fatigue over time. MSI Anti-Flicker technology provides a very comfortable viewing experience by reducing the amount of flicker.

The screen’s resolution is one of the most important specifications, and its importance is growing every day. If you are selecting a gadget with a display, you may be interested in the size of the screen, the number of pixels it produces, and even the number of colours it produces. But what about the refresh rate?

TVs and gaming monitors are two examples of electronics where the refresh rate is something potential buyers consider. In laptops, tablets, and smartphones, refresh rate isn’t as often discussed, but it is something to keep in mind.

Let’s review what the refresh rate actually is at the outset. A TV’s refresh rate refers to how often the picture is redrawn per second, or another way of putting it is how many images it can display in a second. Faster refreshes of a picture should help it appear smoother and have less flicker to the human eye. This is important when you’re watching a sports match or playing a video game, but not so important if you’re editing a spreadsheet or browsing the web.

Refresh rate is measured in Hertz or Hz: That tells you how many times the screen refreshes per second. Televisions, monitors, smartphones, and gadgets all work on the same principle, though some technology details vary.

It simply means that the picture is re-displayed 50 or 60 times every second. There is a 50Hz or 60Hz refresh rate for displays. PAL displays (the standard we use in Australia) operate at 50 Hz; NTSC displays (the standard used in North America) operate at 60 Hz.

Several factors affect how you perceive the image, so the refresh rate may not be the most important. For a long time, 30 frames per second was the standard, and it is still a common refresh rate for older media such as DVDs and 1080p Blu-rays. However, newer media can often take advantage of the newer capabilities to offer higher frame rates that are better suited for your TV. The gaming industry has adopted higher frame rates, offering 60Hz and 120Hz games on the latest consoles.

The higher frame rate is one of the few TV specifications that can easily communicate that one TV is better than another. The frame rate is easy to read and understand; 60 is good, 120 is better, and that’s all there is to it.

In the first place, it’s a good idea to understand how video frame rates differ from television refresh rates. Despite their differences, they have an impact on each other.

First, you should know that a modern flat-screen TV has a native refresh rate of 120 Hz. In other words, it can show 120 images every second. Therefore, you need to decide whether you want a 120 Hz TV – or a 60 Hz TV.

The TV with the highest native refresh rate will be 120 Hz, and all TVs will run at 60 or 120 Hz. Any quote higher than this is a marketing ploy intended to entice you to upgrade to a ‘better’ TV.

Whether you’re a gamer or just a regular TV watcher, be sure to keep refresh rates in mind when choosing your screen! It could make a big difference in your experience. Thanks for reading!

Gamers are always looking for ways to get an edge on their opponents. They can do this by making sure that their monitor has a high refresh rate. This allows the images on the screen to update more quickly, giving the gamer a smoother image and helping them to make better decisions.

Refresh rate refers to how often the image displayed on a monitor (or other display) is updated per second. Hertz (Hz) is the unit used to measure this. Having a higher refresh rate means you see more information in the same amount of time, which leads to smoother motion. Technically, video is just a series of still images that are shown very quickly to produce the illusion of motion.

Refresh rates are important for all users because they affect how quickly the image on the screen updates. A higher refresh rate means that the image will update more rapidly, resulting in a smoother image. This is especially important for people who use their computers for tasks that require them to react quickly, such as video editing or graphic design. However, even people who use their computers for general web browsing or word processing can benefit from a higher refresh rate because it can reduce eye fatigue.

Standard monitors operate at 60Hz. However, you can also find monitors with higher refresh rates, usually meant for gaming. Higher-tier monitors have refresh rates as high as 144Hz or 240Hz. Comparing monitors is easy with these numbers. 120Hz monitors, for example, can display twice as many images per second as 60Hz monitors.

You may not be able to justify the cost of a monitor above 60Hz if you don’t play video games. A higher frame rate will only make a noticeable difference in very few applications other than gaming. If you wish to upgrade your monitor, it’s better to spend your money on a larger display, higher-res, or has better image quality.

A high refresh rate monitor makes a noticeable difference when playing fast-paced games like shooters. While the difference between 60FPS and 144HZ isn’t as significant as between 30FPS and 60FPS, it does matter. Those who play mostly strategy games will probably be perfectly content with 60FPS.

Will you be editing photos and video in addition to regular office work, for example? A TN panel should be enough for basic office work. A VA panel, however, is ideal if you want to edit videos or photos with color accuracy.

It is also important to consider the size and resolution of the display. A 4K monitor with a high refresh rate will be expensive if you want to go to 4K. Are you willing to trade pixel density for smoothness and ease of use?

For most people, price is also a major factor. Even though it might only be 75 or 120 Hz, a better-than-average monitor may include a higher refresh rate. By sticking to a 60 Hz display, you can certainly save money.

Whether you’re a gamer or just a regular computer user, be sure to keep refresh rates in mind when choosing a monitor! It could make a big difference in your experience. Thanks for reading!
