It cannot get any more confusing with all the tiers, but hey VESA loves to make money with their certifications. The Video Electronics Standards Association (VESA) announced today that it has added a DisplayHDR True Black high dynamic range (HDR) specification and standard to include a new 600 performance level. 

The DisplayHDR True Black standard, which is based on the widely used VESA High-Performance Monitor and Display Compliance Test Specification (DisplayHDR), is tailored for emissive display technologies such as organic light emitting diode (OLED) and upcoming microLED displays. The new DisplayHDR True Black 600 tier offers higher luminance than the existing DisplayHDR and DisplayHDR True Black 400 and 500 tiers. DisplayHDR and DisplayHDR True Black are the display industry's first fully open standards specifying HDR quality for LCD and emissive displays, respectively. VESA also announced today that three products have already been certified to the new DisplayHDR True Black 600 performance level - the ASUS Vivobook Pro 14, Vivobook Pro 14X and Vivobook 15 laptops. ASUS is formally unveiling these products at a separate company event today.

DisplayHDR True Black allows for up to 100X deeper black levels in addition to a greater dynamic range and a 4X improvement in rise time compared to VESA's DisplayHDR 1000 performance tier. This enables a visually stunning experience for home theater and gaming enthusiasts. The new DisplayHDR True Black 600 level requires a 20 percent increase in luminance compared to the True Black 500 level, which results in a noticeably brighter screen while maintaining the same outstanding black level and color quality typified in OLED displays.
