What is the max length of an HDMI 2.1 cable that will carry the full 3840x2160 resolution at 144hz? Does cable length matter? I need at least 15ft. Will a 20ft cable work? What about 25ft?

Thanks! null

Both the HDMI and DP cables are short. The ones that came with my monitor were about 3ft, I had to get 6ft for my setup, bummer BUT the monitor is excellent IMHO so no biggie about the short cables.

A Google search shows the optimal length of HDMI 2.1 cable is 10 feet, to get 4K @ 144hz.
