Achieving 8K 30Hz or 4K 144Hz requires a host device that supports DisplayPort 1.4 with Display Stream Compression (DSC) and a certified HDMI 2.1 cable. If the host graphics processor (GPU) lacks DSC support, the resolution will automatically default to 4K 60Hz or lower.

Why Cable and GPU Specifications Matter

Standard HDMI cables do not possess the bandwidth required for 8K or high-refresh 4K signals; an "Ultra High Speed" HDMI 2.1 certified cable is required to maintain integrity of the high-bandwidth video signal. Additionally, the monitor's HDMI port must be rated for 2.1 specifications, as some displays cap their HDMI inputs at lower refresh rates compared to their DisplayPort inputs.
