At least for Nvidia users all you have to do is turn off overscan in the desktop resizing section of the nvidia control panel. The auto setting doesn’t detect the TV correctly. It works every now and then but appears to affect the handshake protocol. The other part is to delete the 4096 x 2160 rez using CRU. You have to have a good eye to catch it but It affects in-game scaling and stretches\resizes. Follow CRU directions and create a task on startup in task scheduler to start the restart64.exe every time you boot. I did both of these steps and the 85k literally went into focus in front of my eyes. Super crisp text, great clarity in games. All the blurry ghosting, blocky unreadable text is gone! Night and day difference. Hope this helps someone…
