Review on 6 Feet USB-C to DisplayPort Cable, BENFEI USB Type-C to DisplayPort [Thunderbolt 3 Compatible] for MacBook Pro 2018/2017, Samsung Galaxy S9/S8, Surface Book 2, Dell XPS 13/15, Pixelbook and More by Michael Montgomery

I have 2 4k monitors (old ASUS and new ASUS). For some strange reason it works fine on the new monitor, but the audio and screen crackle and distort every few moments on the old one. I'm not sure what the problem is but I'm frustrated because I bought this cable to work with an old monitor (two different computer settings) and it doesn't work for me. Could be a bug, not sure.
