Screen blacks out - Monitor or GPU issue?
#1 Posted 19 April 2018 - 12:21 PM
Like I said it doesn't happen on my side monitor but I don't know if that's just because it's not running at 1080p or not. I don't have another 1080p screen to test so I'm just assuming it's the monitor and not the GPU. I at first assumed it might be the GPU as it got worse when I switched over from my old GTX 460 to my current GTX 970. But I think that may have just been a coincidence now....the monitor is 8 years old now or so and the 970 is only a year and a half or something like that.
The monitor is an Asus VK278Q 27".
EDIT: Oh yeah, I also noticed since I just recently bought a Bluray burner drive that when watching Bluray movies with Cyberlink PowerDVD sometimes the screen not only blacks out but turns to snow. Only when I'm playing Blurays. It's really bizarre. Maybe it is a GPU issue after all?

Unplug the monitor power cord. Count to 10 Mississippis. Plug in the monitor.

Pretty safe to say it is the screen as others have also said.
How hot is your screen getting? Could be a heat problem, I've heard that's a thing with LCD panels sometimes and that the PSU in them can get baked out of useful service over time.

the variations in the inputs and signals are the difference in how fast they heat up

That's my assessment as well. I've got a cheap tv with the same problem in my basement. Technically speaking it's an easy fix, but these things are usually built like bricks with no way to get at any of the components without damaging it all.
Did you do a full power disconnect? It will flush the caps which may help, they stay charged all the time and are usually the weakest link.

Something you could do, you could go to a store, buy a UPS, and if it doesn't fix your problem, return it. I did this before with a mouse, and they honored getting me a refund.

Although, my TV is HDMI...but only 720p. Still can test. Either way, it's still happening with DVI (though both monitors are connected via DVI. The second has a D-Sub adapter on it and works fine) so it's surely the monitor.

I did some more searching on this issue and then I found this video of a guy who had the exact same issue as me. In this clip he's connecting his monitor to his gfx card via VGA or DV-I and you can see the flicker. When this happens in HDMI the screen just goes black and sometimes doesn't come back (likely because it's not analogue, like I hypothesized above). Same thing otherwise. He said he called in the warranty and had the monitor replaced 5 years ago. So I have no hope of that. Guess I need a new monitor soon.
