Display Stream Compression
It gets even better on PC, with up to 4K 144 Hz visuals when powered by the latest graphics cards. DSC technology supports 4K UHD visuals via a single DisplayPort 1.4 connection by compressing and decompressing each frame on the fly, with no loss in image quality.
*To enable 4K resolution at 144 Hz with DSC, an NVIDIA® GeForce® RTX 20 series, AMD Radeon™ RX 5700 or higher graphics card is required. For additional information about enabling DSC, contact your graphics card manufacturer.
