Nvidia's G-Sync HDR technology was first hinted at in the early launch of Asus' impressive PG27UQ gaming monitor, and now the company has officially unveiled what is essentially the next evolution in G-Sync displays.
The idea behind G-Sync HDR is similar to AMD's FreeSync 2 technology: it provides gamers with a zero input lag HDR gaming experience on a new collection of top-end monitors. These monitors have been created in partnership with AU Optronics, who have created a brand new panel that will be seen in a range of displays, including the Asus PG27UQ.
All of the PG27UQ's features will be seen in first-generation G-Sync HDR displays. You'll be getting a 4K 144 Hz panel, complete with G-Sync's existing variable refresh technology for a tear- and stutter-free experience. There will also be 384-zone backlights for the highest contrast between bright and dark areas, along with Quantum Dot technology.
Initial G-Sync HDR displays will feature a color space 25% larger than sRGB, which Nvidia says is "close" to the DCI-P3 standard. G-Sync HDR itself, however, supports HDR10, so in the future we can expect G-Sync HDR monitors with even wider color gamuts.
Like FreeSync 2, it appears as though PC games will need to integrate specific support for G-Sync HDR if they want to utilize the full capabilities of G-Sync HDR monitors. Mass Effect: Andromeda and Shadow Warrior 2 are two games set to support G-Sync HDR at its launch, and we can expect more titles to support HDR on PC in the future.
G-Sync HDR monitors from Asus and Acer will be available later this year, although Nvidia didn't state specifically when.
