VESA Establishes `ClearMR’ Motion Clarity Standard For Video Displays
The Video Electronics Standards Associated (VESA) announced Monday a new reference standard for testing and determining a monitor or television display’s ability to produce motion clarity.
VESA said the standard, which applies to both LCDs and self-emissive displays like OLEDs, was developed to provide an alternative to standards like Motion Picture Response Time (MPRT) and Gray-to-Gray (G2G) based primarily on time measurements, that manufacturers can cherry pick to produce the best rating for specs and advertising materials.
VESA, instead is focusing on the ratio of the number of clear pixels to blurry ones, and a compliance testing procedure to determine that, which a manufacturer must conform with in order to use one of its ClearMR performance certification badges in marketing and sales materials.
The new VESA ClearMR is a system of seven critera levels for ranking a display’s ability to present the clearest fast moving images. The rankings assign ratios of clear to blurry pixels, starting at ClearMR 3000 (the lowest motion clarity) up to ClearMR 9000 (the highest level of motion clarity).
So for example, a display with ClearMR 7000 would have a clear motion ratio with 65 to 75 times (6500 to 7500 percent) more clear pixels than blurry pixels.
This new scale and testing methodology is only the start of the ClearMR program. VESA said the current version of the specification and logo program only applies to a displays ability to handle motion when tested in standard dynamic range (SDR) mode. The Association is working on an update to bring a testing mode for high dynamic range (HDR) in the future.
VESA said each ClearMR level presents a “visually distinguishable change in clarity”. This will be applicable to a variety of consumer displays, including laptop and tablet screens.
VESA is an industry association focused mainly on PC/IT oriented monitors and display technologies, but its standards (like display wall mount measurements) sometimes apply to regular televisions as well.
In the past, the association had developed the DisplayPort connection standard for PC monitors, the DisplayHDR set of standards for determining the level of performance of and HDR enabled monitor, and AdaptiveSync, a PC monitor gaming standard intended to eliminate or reduce screen tearing and game stuttering between displays and graphics cards.
Whether or not the ClearMR standard will be embraced by the television side of the consumer display industry remains to be seen. To date the DisplayHDR program has been used primarily on PC monitors, and virtually no consumer television on the market includes DisplayPort inputs any longer.
VESA presented a list of the first displays certified for ClearMR, which at this time includes mostly LG’s gaming monitors, rated for ClearMR 6000 or 7000.
