The technology NVIDIA G-Sync will increase monitor price by $ 120, but instead promises to remove from the gameplay video artifacts and frame loss - make it visually smooth.
AMD company , as it became known during the CES 2014, too, can offer something similar, but almost free. However, the display controller, to be exact - image scaling ASIC, should be able to work with a variable refresh rate. Secondly, LCD-panel, too, must be able to work with a variable refresh rate. Interestingly, both technologies from NVIDIA and AMD are based on the same standard VESA, providing management personnel duration blanking VBLANK.
NVIDIA representative commented AMD demonstration. Competitors, said technology developer G-Sync, Pererson Tom (Tom Petersen), used the laptops where the interface between the panel and the video card is different from the ligament between the graphics card and a desktop monitor. Usually it LVDS or eDP (DisplayPort embedded solutions). These interfaces have been necessary extensions to work with variable frequency vertical deflection that is supported, including logic for video scaling.
With Desktop monitors all wrong. Manufacturers are in no hurry to build in support for their ASIC AC VBLANK. So NVIDIA made a specialized matrix for scaling and has built the necessary support for GPU. Therefore, by the way, NVIDIA is not going to share the G-Sync technology with AMD. NVIDIA offers to take advantage of G-Sync in the near future, but for a fee of a couple of hundred dollars for a compatible monitor.
