OH ! If we are talking monitor, my relatively brand new one is making me shit bricks these days. I still think it's a software issue but jeez.
Basically, each time I open an openoffice document, and rarely when doing other things like that, my monitor goes black for 1/2 second, like when you change resolution.
What. The. Fuck ?
I had a very strange "random 1/2 second of black screen" issue that I never properly understood.
A years or two ago, I was playing Sekiro with ReShade. (1st playthrough; I installed ReShade right away, because I didn't like the washed out colors at first. I had the monitor for 2+ years at this point.).
After 10-ish hours (over several sessions) I got a half-second of black screen, apropos of nothing. Then another a couple of hours later. Then another, say, an hour later, and another and another, with increasing frequency, to the point that it detracted from gameplay. Restarting the game helped, but not a lot. I told myself: "Sekiro has issues".
Then I started getting them when
not in game. Ah. I told myself, "actually it's a windows / drivers / whatever issue, possibly aggravated by running Sekiro". Maybe I updated something at the same time I started playing the game. Since I only use Windows for gaming (I have a Linux dual-boot), I spend little time in Windows and not in game. Still, strange that the frequency of black screens increases so visibly while playing; the longer the session, the greater the increase.
Then, after a long Sekiro session, I rebooted into Linux to get on with my day. Email. Blah blah.
And then it started. I quickly got a random black screen. And another. Whatever it was, it was a
hardware issue. I did not touch Sekiro for weeks (I played something else), and it gradually went away.
Months later, I tried Sekiro again, wondering if I had imagined a correlation between Sekiro and the issue, or whether it had been an accidental correlation perhaps. At first all was fine, but after a couple of hours it started again. No longer any doubt about the culprit.
At this point, I remembered about ReShade and removed it. Still played Sekiro. I now have ~220 hours in it. The frequency of black screens kept diminishing, and after a couple of months disappeared almost entirely.
So it was ReShade. There was something in it that somehow "fatigued" either my GPU or my screen. I have no idea how such a thing is even technically possible.
(I have another mysterious issue where the screen sometimes goes black, and
stays black, highly correlated to my getting out of my chair (!!?). I have to restart it with the button when that happens. It started rather recently. I assumed something to do with cables being jiggled by vibrations or whatever, but couldn't reproduce, don't have a single, solitary clue.)
