I have two 144hz 4ks, which have been… difficult.
First, I’m just happy to have them. I initially solved some issues with “gray” screens, tearing, and general unresponsiveness by buying new DisplayPort cables. Like many of you I suspect, I have a giant stack of misc cables, but I bought some new ones and that seems to have fixed a big part of the problem.
Now though, I can’t get them to go to sleep. I have a 3rd monitor attached that goes to sleep just fine, but neither of the Spectrums go to sleep. The indicator light also doesn’t change. One screen even turns solid green… I’ve changed the behavior of the indicator light to make it very obvious. Still no luck.
