VESA (Video Electronics Standards Association), which sets standards for monitors, has expanded the specification standards for modern displays. The ClearMR motion image output standard has received three new levels, which indicate the most accurate reproduction of dynamic scenes; brighter OLED displays will now be able to receive the DisplayHDR True Black 1000 labeling.

In August 2022, VESA launched a new display certification program that replaced Moving Picture Response Time (MPRT) with multiple gradations of Image Clarity Ratio (ClearMR or CMR). In accordance with the specified criteria, products are tested, on the basis of which manufacturers certify them according to one of the CMR levels, after which they use them in advertising materials. The CMR value reflects the ratio of clearly visible to blurred pixels: ClearMR 7000 corresponds to a range in which there are 65-75 times more clear pixels than blurry pixels. The higher the number, the less blur.

At first, the highest level was ClearMR 9000. In January 2023, VESA introduced ClearMR 10000, ClearMR 11000, ClearMR 12000 and ClearMR 13000 – required by the advent of OLED monitors with a refresh rate of 240 Hz. Now that 480 Hz models have appeared, the organization has introduced new standards for them too – they are called ClearMR 15000, ClearMR 18000 and ClearMR 21000. The ClearMR 21000 certificate was received by the LG 27GX940 model, and new OLED monitors from Gigabyte, MSI and Samsung will apply for it.

The VESA DisplayHDR standard is used to classify the suitability of displays for displaying HDR content. In 2019, DisplayHDR True Black became its offshoot – the certification takes into account the indicators of maximum brightness and black depth. Until now, the highest level was DisplayHDR True Black 600, which requires a specific brightness of at least 600 cd/m². The new standard is called DisplayHDR True Black 1000. It assumes a peak brightness of at least 1000 cd/m² and a constant brightness of 500 cd/m² across the entire screen. There are no intermediate levels between the new standard and DisplayHDR True Black 600.
The requirements put forward for the new version are extremely high. At the moment, no display has yet received DisplayHDR True Black 1000 certification, but, as VESA reported, Samsung specialists are already working on this.
