So I've been having this issue where my monitor will appear to shut off for a couple seconds every so often, giving a blank screen until it returns as if nothing happened. I can't figure out the trigger; it's happened while playing games or sitting on desktop, and there's no discernable pattern to when it's going to occur. I'll just be doing something, the screen will go blank for a moment, and then things will continue as normal, all without interrupting any programs running - even music will play normally throughout the event. There's no error logs or anything, and there's been no big hardware changes for the last couple months. It's only happened three times in a couple weeks.
A bit of hardware history: I have a
GTX 970, Windows 8.1, and the monitor is a
Dell ST2421L. A few months back I upgraded my PSU and graphics card to what I have currently. I also dusted my computer recently--just after the problem started happening--but that didn't fix it. (Didn't think it would, but hoped... though now that I think of it I've never really tried dusting the monitor.)
My google-fu has lead me to believe this monitor blackout problem is due to a faulty/failing monitor. I'm not certain, but inclined to agree. I've had it since I got my computer a few years back, no potential issues until now.
TechSupportGAF, what do you think could cause such an issue? All help is appreciated.
