Simply put, G-Sync technology is to control the frame rate output and display refresh rate of the graphics card by the graphics card to ensure that the screen is not stuck, no tear, no ghosting, no blur, NVIDIA also provides a complete certification process, passed Can be labeled with G-Sync.
After that, NVIDIA added HDR high dynamic range display technology to G-Sync technology.It can provide color performance that is close to the human eye's perception range and has a better display in terms of color depth, color gamut, and brightness.
Take "Final Fantasy 15" as an example, the performance of G-Sync HDR displays is obviously superior to that of the others.Highlighted areas, bright and dark areas are displayed at the same time without losing detail.
In addition,G-Sync HDR monitor supports up to 240Hz ultra-high refresh rateThis ensures that almost any game, especially an FPS game, can achieve a sufficiently high frame rate and fluency under any conditions.
Of course, this also requires the support of powerful graphics cards, but with high resolution and high image quality, there is hardly any game other than "CS:GO" that can achieve a crazy frame rate of 240 FPS. Can only say that G-Sync HDR leaves enough room for future development, enough graphics and games to catch up for a while.
G-Sync HDR displays also have NVIDIA official certification, and because the technical requirements are more demanding, the certification is also more rigorous and complex, especially the selection of the screen panel, from the refresh rate, response time, color gamut / color contrast / contrast color Qualities and other aspects of the investigation, only this will eliminate about 90% of the market screen, and finally after the display is manufactured to conduct the same final test, all qualified to enter the G-Sync HDR category.
NVIDIA also introduced us to two top G-Sync HDR displays.One is ASUS's ROG Swift PG27UQ, and the other is the Predator XB272-HDR. They also support 4K resolution and 144Hz refresh rate. It is the most advanced monitor at present.
4K 144Hz does not seem to be of practical value at present, there is no graphics card can support 4K resolution games can run such a high frame rate, but in NVIDIA's view,On the one hand, the replacement frequency of the display is much lower than that of the graphics card. It can use five or six years. During this period, graphics cards and games will continue to evolve. It may not be a problem for the next two generations to support 4K 144FPS.
On the other hand, the monitor is not only used to play games, but also enjoy watching high-frame movies.For example, Li An's "Billie Lynn's Midfield War", the first film based on the 120FPS frame rate, is more appetizing on such a high refresh rate monitor.
