This is a total shot in the dark, but maybe I’m lucky:
I use a Samsung TV as a monitor and every time I switch inputs on the TV, it “disconnects” from my PC and my NVidia card (GTX 950) resets the resolution back to the default 1024×768 or whatever and when I switch the input back to my PC, it does set it back to the full 4K, but now all my windows have been sized down into the top left corner of the screen. Super-annoying.
Now, here’s the thing: I upgraded my graphics drivers some time around a year or so ago (not exactly sure, could be anything between 20 and 6 months ago) and the problem disappeared! Basically, those drivers would either simply remember the EDID of the monitor or otherwise not care that it was “disconnected”.
Unfortunately, I had since forgotten about the issue and recently upgraded my drivers again and now the problem is back. And, of course, I didn’t think to keep the install files or any other information of the previous drivers around.
Which leads me to my long-shot question: Does anybody happen to know which driver version this may have been? Or is there a way to see my driver version install history? Or is there maybe some other switch or trick to fix the issue with?
