Playing 4K images at more than 120 Hz is complicated. Basically, the bandwidth of the DisplayPort 1.4 standard is not enough to make it possible, and for this it is usually necessary to reduce the quality of the image with techniques such as chroma subsampling (or “commuting subsampling”). At the E3 2019 fair, AMD and Asus have shown the “first monitor in the world with support for” Display Stream Compression “& DSC.” It is a compression technique for DisplayPort that, in theory, has no losses. can guarantee resolutions from 4K to 144 Hz without relying on chroma subsampling, so it is no longer necessary to choose between resolution, refresh rate or chromatic quality.
DSC technology will be available on graphics cards Radeon Navi RX 5700 That will arrive on July 7, and Asus has advanced to the monitor of the ROG line, which still has no name, but which will have a 4K panel with a diagonal of 43 inches and a refresh rate of 144 Hz, FreeSync 2 and certified with HDR 1000 Display It seems an improved version of the ROG Strix XG438Q that was presented at CES 2019, but currently it is not known if it is so or is a new monitor.
