Works well on about 100 feet of Cat5E cable (solid copper, existing cabling) at 4K at 60Hz and even runs fine at resolutions like 3840 x 1600 at 75Hz. Also with USB peripherals (mouse, keyboard, bluetooth Headphones) there is no noticeable lag. Cons: HDMI audio only seems to work at resolutions around 1080p, otherwise there's no sound. I never found out why as my setup doesn't require it. Transferring large amounts of data/memory via USB is very slow.
