NVIDIA introduced the first G-Sync PC gaming monitors with a 144Hz refresh rate at CES last year. It has now announced the expansion of G-Sync support to other monitors compatible with AMD’s FreeSync technology. A total of 12 FreeSync monitors have been registered to receive G-Sync support. Support will be rolled out via a software update, with no additional hardware required. NVIDIA has also redesigned G-Sync HDR in G-Sync Ultimate.

G-Sync Ultimate is an adaptive sync technology that matches the frame rate of a monitor with an NVIDIA graphics card using specialized hardware. The technology is similar to AMD's FreeSync technology. The G-Sync program is categorized into three levels – G-Sync, G-Sync Compatible, and G-Sync Ultimate. Monitors that support AMD's FreeSync are labeled as G-Sync compatible.
According to NVIDIA, around 400 monitors have been tested and only 12 of them were selected. It plans to test 100 more monitors in the near future to check whether they are G-Sync compatible or not. The twelve FreeSync monitors confirmed to support G-Sync are Acer XG270HU, Acer XFA240, Acer XV273K, Acer XZ321Q, ASUS VG258Q, ASUS XG248, ASUS VG278Q, ASUS MG278Q, AOC G2590FX and Agon AG241QG4.
NVIDIA also says that G-Sync Ultimate technology will be ported to its 65-inch G-Sync HDR monitors, which it has dubbed the Big Gaming Display (BFGD). The first manufacturer to bring BFGD will be HP, which will bring the technology with the Omen X 65. The display will feature NVIDIA Shield TV built-in, a 120Hz refresh rate, and 1000 nits of brightness.
