Lower response times are better. It is not the same as input lag — which is a specification that display manufacturers do not advertise. Input lag is the delay between a keystroke or mouse click and the result happening on the screen. The monitor response time, on the other hand, is specified by the display manufacturers but only for monitors, not for TVs. You might hear all about screen size, resolution, color reproduction, and refresh rate, but response time is discussed less among people.
It is a measure of how quickly a pixel can display a change from black to white or from one shade of gray to another. Different shades of gray represent how intense any given color will appear on your monitor through a filter.
Response times are often given in milliseconds since one frame on a standard 60Hz monitor stays on your screen for just under seventeen milliseconds. The pixels themselves need to transition more quickly than that so that they can display the next frame in time. This is when you can see the remains of trails from a moving object on a screen because pixels took too long to switch between shades of gray.
This is really not a huge deal if you just use your computer for everyday browsing and social networking, but if you are a gamer or like to watch movies with fast action, then poor response times can cause really distracting visual artifacts.
Moreover, they have the worst color reproduction out of the three panels. The TN panel monitors are therefore mainly used by professional and competitive gamers, and paired with a higher Hz refresh rate for the smoothest fast-paced gameplay experience.
While the IPS panels have more accurate and consistent colors, VA monitors offer a higher static contrast ratio. This makes the IPS monitors ideal for color-critical work while those who want deep blacks and bright whites should go for a VA panel display.You can carry out 13 individual tests to check how uniform the image display is across the entire monitor, for example, or if the text is displayed sharply. You can check your monitor for defective pixels and get a sense of its viewing angle stability.
Put your monitor to the test now! The EIZO monitor test consists of various test scenarios that your monitor can handle to a greater or lesser extent, depending on the model. For example, gaming monitors are distinguished by particularly short response times, whereas graphic monitors impress with a particularly homogenous image display and smooth gradients. You should therefore always assess your monitor within the context of its respective device category.
For this reason, please note the manufacturer specifications especially for the defective pixel test.
What Does Monitor Response Time Mean?
It is recommended that you carry out the monitor test in a dark room. This allows you to precisely assess even dark image areas. In order to ensure meaningful test results, your monitor should already be warmed up prior to testing ideally for 30 minutes.
You should also clean the display prior to testing, since reflected light could cause dust particles to look like defective pixels. Ordering and questions 1 or contact us. Note The EIZO monitor test consists of various test scenarios that your monitor can handle to a greater or lesser extent, depending on the model. Preparation In order to ensure meaningful test results, your monitor should already be warmed up prior to testing ideally for 30 minutes.Type of Display: This test is primarily designed for LCD displays steady backlight, sample-and-hold displays.
Instructions: Watch the UFO. Slowly adjust the "Pixel Per Frame" by 1 until background looks like a perfect checkerboard with the dark and light squares as exactly the same size as possible. For the scientifically ideal instant-response sample-and-hold display, MPRT is exactly equal to the time period of one refresh cycle. For the scientifically ideal impulse-driven display e.
MPRT is also known in some industry circles as "persistence". For more information about display persistence, see Blur Busters Law. Techniques such as frame-interpolation and impulse-driving scanning backlights, strobing frequently combine to create higher Motion Clarity Ratios MCR.
It represents the same perceived display motion blur as an ideal sample-and-hold display refreshing at a Hz matching the MCR value. This test allows you to measure the actual correct representative number as seen by the human eye, which may sometimes be lower than advertised numbers. Note: This motion test is compatible with impulse-driving.
However, this motion test will not work with frame-interpolation. LCD GtG pixel transitions are often asymmetric. However, faster displays and higher refresh rates are easier with a smaller "Size" setting. Avoid Thickness values bigger than Checkerboard Size. Test for short periods at a time. Rest your eyes between tests. Keep Aero turned on. Check Your Browser. Frame Rate.

No cherry-picked units sent by brands. Motion blur is a characteristic of displays that causes moving elements to appear blurry or to have a long trail following them sometimes called smearing. There are a few elements of a monitor that cause motion blur, but one of the largest reasons is pixel response time.
The response time is the duration required for a pixel to change from showing one color to another. The slower the response time, the longer the trail following moving objects will be.
Motion blur is important to consider if you use your monitor for watching sports or for playing video games since blurry motion can be quite distracting. To test for motion blur, we take a picture to capture the appearance of the blur shown on screen as well as precisely measure the pixel response time using a specialized tool. However, some people might dislike monitors with low motion blur when watching 24p movies, since it can give the content a stuttery, jarring look.
While those users might prefer to have some motion blur, too much of it is an annoyance for most people. To accurately capture the appearance of motion blur, we use the Pursuit Camera test methodology developed by Mark Rejhon of Blur Busters.
It consists of a test pattern moving transversally and a camera placed on a rail that sits parallel to the screen. Part of the methodology is also a validation system which uses a series of temporal tick marks positioned below the logo. This technique helps create consistent and representative pictures of the blur created by the monitor.
The second picture in our motion blur test is our response time graphs. These charts are based on data that is produced by our own multipurpose tool which uses an array of photodiodes and an Arduino Due connected to our test computer via USB.
To test for response time, we display a series of grey slides on the monitor, and place on the display our photodiode tool. While the sequence of grey slides appears on-screen, the tool continuously captures the light intensity coming from the display.
This allows us to calculate the time it takes for the pixel to transit from displaying one shade to another, thus giving us a response time measurement. To produce a representative value, we measure 12 transitions in total. This helps determine the length of the trail left behind moving objects. This test notes the monitor's setting which provides the best motion blur performance within our test without having too much overshoot. This is the setting at which our test results are captured.
While our motion blur test is centered around the response time, the general cause of motion blur is what is called "Persistence". Essentially, the longer a frame is kept on screen before switching to the next one, the blurrier a moving object will appear on-screen. While response time is a good way to reduce persistence, it is greatly affected by other aspects of the screen such as its refresh rate as well as the monitor's ability to use a flickering backlight also called black frame insertion, BFI, or ULMB which reduces the time a frame is shown.
While the transition time might be instant, the lower amount of "steps" for motion requires our brain to do additional compensation leads to blurrier movement. We've made a series of videos which explain the different aspects that affect motion which you can find on our Youtube channel. Motion blur is a generally undesirable effect that causes motion to looks less sharp.
EIZO Monitor Test
It appears on essentially every monitor, but some have far less of it than others. It is generally best to have as little of it as possible. An important part of motion blur is the response time, which is the amount of time in ms necessary for a pixel to change from displaying one frame to another. However, other aspects such as refresh rate and image flicker can also affect the amount of blur that appears on-screen and are important to consider when shopping for a monitor that produces little motion blur.

MPRT represents how long a pixel is continuously visible for. Even when a pixel finishes its GtG transition from one color to another color, a fully refreshed pixel can stay continuously visible or static until the next refresh cycle.
GtG versus MPRT: Frequently Asked Questions About Pixel Response On Displays
Even though GtG pixel response time has become faster e. High MPRT creates a longer sample-and-hold effect caused by eye-tracking. Source: Microsoft Research. As you track your eyes on moving objects on a screen, your eyes are in a different positions at the beginning versus end of a refresh cycle.

Image Credit: www. Pixel response can be a tiny fraction of a refresh cycle, and still produce human-visible artifacts such as ghosting or coronas — especially if pixel transitions are different speeds for different colors. Millisecond-scale imperfections and asymmetries in pixel response appears as distortions to motion blur, such as this:.
Faster pixel response becomes more important at higher refresh rates such as Hz. Once GtG is already fast, there are only two ways to further reduce MPRT display motion blur: A Shorten pixel visibility time via adding black periods between refresh cycles.
B Shorten pixel visibility time via adding more frames per second at higher refresh rates. Accomplishing B in current technology, is often done via upgrading to a higher refresh rate along with a faster GPU.
Without motion blur reduction, doubling the frame rate and refresh rate halves display motion blur. As a rule of thumb, MPRT is more linked to frame rate on an sample-and-hold display. The motion blur of 60fps can look identical on a 60Hz, Hz and Hz display, since a lower frame rate creates a longer pixel visibility time longer persistence on a sample-and-hold display.
Bear in mind, GtG response will also add extra artifacts ghosting, coronas, blurring above-and-beyond the above chart. Impulsed-driven displays strobe-backlight, impulsed, phosphor, black frame insertion can reduce MPRT by shortening pixel visibility time:.
Instead of being controlled by the refresh rate, the motion blur persistence, MPRT of an impulsed display is controlled by how long a pixel is visible for: The length of the backlight flash, at one flash per refresh cycle. Usually, most strobed displays e.
The faster the GtG, the easier it is to hide GtG in darkness between strobed refresh cycles! As a result, it is now possible to have MPRT numbers smaller than GtG numbers, if the panel GtG pixel response is hidden unseen from eyes in the dark period between backlight strobe flashes.
There is a valid reason why manufacturer GtG specifications are often more aggressive than real-world GtG numbers.
Graph taken from hal. Measuring electronically is more reliable with cutoff points, especially back in the old days. On an 8-bits-per-channel display bit colorthere are different grey levels for each channel red, green, blue.
Different shades can have different GtG pixel transition speeds from one source color to one destination color. Thus, there are thousands of different GtG numbers for the same panel!
