The new standard to recognize the best monitors and TVs for gaming and live sports
The so-called motion blur, precisely this sort of blur or trail that accompanies a dynamic subject, is closely linked to the response times of the panels. The lower it is - measured in milliseconds - the sharper and more fluid the images appear; if high, on the other hand, moving subjects tend to have a trail. Today it seems that any panel, monitor or TV travels at 1 millisecond, so the maximum you could wish for, but in reality the visual experience varies considerably from model to model.
ClearMr, clear motion ratio The label ClearMr will soon begin to spread in the sectors of monitors, laptops, tablets, all-in-ones and TVs. In practice, in any IT environment where there is a flat screen panel. The good news is that this program provides a series of levels with a numerical value that will allow you to immediately understand the quality of the device: a sort of classification.
For example, the ClearMR 7000 label identifies a clear motion range ratio between 6,500 and 7,500: in practice the ratio between clear and blurred is 65–75: 1, which means that you get 65-75 times more sharp pixels than blurred ones. The minimum threshold is ClearMR 3000 and is valid for screens of at least 90 Hz (below these Hz they cannot be certified), while the current maximum is ClearMR 9000.
VesaThe diffusion of this certification is obvious since Vesa includes all the reference manufacturers in the sector such as Intel, Samsung, AU Optronics, LG and Lenovo. On the board sit executives from Apple, AMD, Qualcomm, HP and other leading companies. A first list of certified Lg and Hp monitors is already available on the official website.
Differences between ClearMr and Mprt The response speed of monitors and TVs has become a very hot topic especially with the success and diffusion of more frenetic video games and the enjoyment of live sporting events. In recent years, the industry has buffered by indicating in the technical data sheets the Mprt or GtG data which correspond respectively to moving picture response time and gray-to-gray. There are two different ways of indicating the response speed of the panels, but over time, thanks to the introduction of different technologies, the metrics have skipped and in fact it seems that all the new products on the market are very fast.
Mprt measures the time taken by a panel to change the pixels from black to white and then to black, but this data is no longer sufficient because more and more technologies are exploited which in improving the quality of the images produce artifacts or distortions in the phases of movement. The same goes for GtG which measures the time it takes a panel to change a pixel from one shade of gray to another. In reality, you take a hypothetical photograph of the transition moment but you don't know which one: it could be light gray to dark gray, or medium gray to light gray. It is foreseeable that the ideal moment for marketing will be chosen.
In summary, the data on speed no longer means anything because it does not reflect the experience of use that the consumer expects.
The test ClearMr ClearMr in theory seems to have what it takes to clarify because it starts from an analytical basis of image quality at the pixel level. As Dale Stolitzka, one of the Samsung Display researchers at Ars Technica explained, the test methodology chosen is very accurate. In practice, a series of detections have been established including the movement of objects at 15 degrees per second: a very high challenge threshold that fully meets the needs of the gaming world.
Vesa ClearMR test
Vesa Certification tests include an ambient temperature between 22.5 ° and 24.4 °, a factory setting as default, the native screen resolution, the maximum refresh rate and the strobe backlight disabled. In addition, the weight of the so-called overdrive and its incidence is also estimated.
During the test a bar with different brightness levels moves across a portion of the screen and is measured with a fixed camera - obviously the distance depends on the size of monitor or tv. The captured frames let you understand what the user experience will be since at that point it is a calculation of sharpness and blur relative to the pixels.
The only current limitation of the ClearMR is that it is based on the analysis of contents sdr (standard dynamic range), while for those hdr (high dynamic range) we will have to wait for a next update.
