I'm using short, high quality HDMI 4k 18Gbps cables, but the video randomly freezes. I even replaced all the cables with a different brand. The same cables do not cause any problems when connected directly between the PC and the monitor. There are also problems when switching between two PCs when the mouse speed reaches a crawl that requires a restart.
