Yesterday, we reported that Nvidia had quietly decreased the requirements for a monitor to receive the G-Sync Ultimate certification from Nvidia. The company previously required the monitors to support ‘Best HDR with 1000 nits brightness’, which has now been changed to ‘Lifelike HDR’ on Nvidia’s site. Nvidia had also erroneously added the Acer X34 S (HDR 600) monitor in its G-Sync Ultimate supported list, which was why people had started believing that Nvidia downgraded its G-Sync Ultimate technology.
Today, the company responded with a clear statement to clarify its position regarding the situation. In a statement the company wrote, “While the original G-SYNC Ultimate displays were 1000 nits with FALD, the newest displays, like OLED, deliver infinite contrast with only 600-700 nits, and advanced multi-zone edge-lit displays offer remarkable contrast with 600-700 nits. G-SYNC Ultimate was never defined by nits alone nor did it require a VESA DisplayHDR1000 certification. Regular G-SYNC displays are also powered by NVIDIA G-SYNC processors as well.”
@nvidia has confirmed (although not to us directly) that the X34 S should not have been listed as 'G-SYNC Ultimate' and that was an error. VESA DisplayHDR 600 capability will be accepted as the minimum it would seem. Hopefully the bar won't be lowered further.

The statement shows that 1000-nit brightness or VESA DisplayHDR 1000 support was never the necessary condition for the displays to be eligible for the G-Sync Ultimate standard. Additionally, these were only LCD screens that do not offer high contrast ratio at low brightness levels compared to the newer OLED displays that offer very high contrast at relatively low brightness.
OLED screens are one of the best displays to consume HDR content nowadays and Nvidia’s move towards OLED displays shows that the company wants to be as accessible for its customers as possible. On the other hand, the edge-lit LCDs are considered to be worse than the LCDs that support FALD (Full-Array Local Dimming) backlights and Nvidia has added the former to its list of supported displays. It is unclear how these displays will be able to deliver image quality comparable to the image produced by the OLED and FALD displays.
Another thing to note here is that Nvidia requires the regular G-Sync displays to be powered by its G-Sync processors as well. These processors serve as the necessary condition for a display to be called a G-Sync capable unit irrespective of the tier.
