XB271HU - screen briefly and randomly turns off (half second sort of thing)
Very, very odd issue.
Bought my XB271HU a month ago - pretty nice piece of hardware, though pricey.
Recently - and this is very strange - it will sometimes go 'blackscreen' very quickly, for a half-second or so, sometimes when I stand up to move away from the computer, and other times at random, before going back to what looks like normal. I thought I was going crazy, but Googling showed some other people with this issue too. Possible issues that people talked about were electrostatic discharge, a bad DP cable, general hardware fault, or a driver issue (Nvidia).
It seems (I could be wrong) to have started after a recent NVidia driver update, but my memory could be wrong.
As a few notes:
- The connection/cable seems fine; I even tried a higher-end aftermarket DP cable to see if the stock ACER one was the issue, and the problem actually became worse.
- The monitor has not been hit or bumped excessively at all, so I doubt any physical damage has occurred.
- The suddent-blackscreen-then-normal-again incidents remind me almost of what it looks like when a driver fails or installs - a brief flash of black for a half second, then the display comes back.
My main question is whether this is likely hardware or software related. I already returned one of these to Amazon for extreme IPS backlight bleed; this one looks really good, and I'd hate to return it unless there's absolutely definitely something wrong with it on the hardware end. I only have a few days to return this for free to Amazon should this be a hardware issue, otherwise it's ACER RMA, or hope this is a software/simple issue that doesn't require repair/replacement.
Anyone heard of anything like this or have any experience that's similar?
