Ok, tl;dr time. Need a 4K HDMI switch that is actually capable of switching a 4K input without glitching out all the time. Needs to be IR and have discrete commands for changing to specific inputs, rather than a Next/Prev system, and have 4+ inputs. Been through a few of the cheaper ones on eBay and a couple from Kogan, but none actually sync up on 4K. All of them do this sort of glitching: Anyone have one that actually works?
