Not sure if either my computer couldn't handle the DisplayPort 1.2 or the cable.Apple limited HDMI-Transportstream over USB-C/TB to maxed found a solution to get more than this working! I read people would alter some monitor settings, I didn't expect much but luckily my monitor allowed me to swap the DisplayPort version. I knew the cables were alright and the monitors would work fine with Windows and through the DisplayLink (via the Dock). I was reading up on compatibility, but I couldn't really figure out what was going on. I tried both USB-C to HDMI as well as USB-C to DisplayPort cables, which both gave the issue that the monitor would show up for a couple of seconds after the signal dropped again. For this to work on the Mac, I needed to install DisplayLink software, but for the 4K monitor, this causes lag because of CPU spikes when the graphics card needs to do stuff. When I tried to hook up my AOC 4K monitor, I first tried it through my Lenovo Thinkpad Dock.
After that, my USB-C to DisplayPort cable works as just fine, without lag and in all resolutions (up to 4K). What worked for me was to go to my monitor settings, where I could change the version of DisplayPort signal from 1.2 to 1.1. I've raised the issue to the Apple support, but of course no answer, and I think no hope of this getting solved.īasically, I need to buy a new screen. It also seems to be a software problem, since it works under Windows/Bootcamp (!)
It looks like incompatibility between MacOS and this iiyama model (or I guess this DisplayPort version). Is it possible that my external display isn't compatible ? I've tested the cable, adapter and screen with another computer and everything works fine.
