New standard VESA ClearMR ratings display motion clarity and can replace monitor response time specifications.

In the context: In most cases, monitor manufacturers advertise pixel response times that are completely useless and misleading. The Video Electronics Standards Association (VESA) hopes to help consumers make better buying decisions on the fly with its new ClearMR certification program. However, you should still do proper research and read independent reviews before buying any display.

Video Electronics Standards Association (VESA) announced ClearMR, a new certification program for motion clarity measurement displays. The ClearMR program and logos apply to LCDs and self-emitting (OLED, microLED) displays, including monitors, TVs, laptops and tablets.

Most monitor manufacturers currently only advertise gray to gray pixel response times at best, which can be misleading for several reasons. Companies sometimes take measurements at unrealistically high ambient temperatures due to the fact that the response time improves significantly as the display heats up. They also usually choose the best result rather than averaging several different G2G transitions.

Most importantly, gaming monitor manufacturers typically run these tests at exaggerated overdrive settings, which results in significant pixel overshoot (reverse ghosting) and thus a significant degradation in image quality. The new standard aims to provide a better motion clarity metric by measuring how blurry a moving image looks on a given display, rather than just touting a measurement based on time (pixel response time).

The ClearMR certification logo includes several levels of performance, from ClearMR 3000 to ClearMR 9000. Each level represents a range of motion blur performance based on the ratio of clear to soft pixels. For example, the ClearMR 5000 has a CMR (motion detail ratio) range of 45 to 55 times (4500 to 5500 percent) more clear pixels than blurry pixels.

When testing, VESA uses a high-speed camera that takes pictures of the test pattern as it moves across the screen as it transitions from one frame to the next. During certification, maximum dimming, dimming, and dimming limits are imposed, and backlight strobing is disabled. If a display does not meet all of these conditions, it will not qualify for the VESA Certified ClearMR logo.

There are currently only a few ClearMR Certified Products – HP Omen 25i and several LG monitors (some are region-specific options that work the same). Interestingly, the LG 48GQ900 OLED display only received ClearMR 7000 certification. Modern OLED panels usually have fantastic pixel response times without the need for overdrive, so it will be interesting to see which type of display will meet the highest ClearMR level (maybe the Alienware AW3423DW QD- OLED with higher refresh rate?).
