VESA DisplayHDR 1000 certification is no longer required
Nvidia quietly lowers G-Sync Ultimate monitor requirements.
Later, the growing popularity of monitors supporting the competing VESA Adaptive-Sync technology, which does not require a hardware block, forced Nvidia to split its technology into three branches: G-Sync (with Nvidia module), G-Sync Compatible (without one), and G-Sync Ultimate (monitors with higher specs and HDR).
At the recent CES 2021, Nvidia announced that three new gaming monitors had received G-Sync Ultimate certification. Two of these were not VESA DisplayHDR 1000 certified, which went against Nvidia’s recommendation for G-Sync Ultimate monitors. It turned out that during this time, Nvidia removed the mention of 1000 cd / m2 brightness, replacing it with the vague wording of “realistic HDR.” As a result, two VESA DisplayHDR 600 certified monitors have received the G-Sync Ultimate badge.
