...and there's nothing wrong with my system. I've been experiencing this "bug" for several weeks now and I'm hoping that my wonderful NEC is not nearing the end of its life (there's no reason it should be). Every so often, for no reason whatsoever, the NEC blacks out for a split second, just a flicker, and then returns as if nothing had happened, displaying the "DVI DIGITAL 1920x1200" banner in the top left of the screen. I don't get any problem reports in Windows, nor is there a message that says the graphics driver has failed, etc. And what's more, I've just done a clean install of W7 on a brand new HDD and the problem is still there. I'm also running a second monitor, a 20" Eizo S2000, and the blackout doesn't affect this monitor, just the NEC. I tried switching the outputs on my graphics card and that didn't change anything, so I'm suspicious that it's the monitor and not the PC at fault... but how can I be 100% sure? I'm suspicious that it could be a driver fault, but perhaps I'm in denial and my monitor really is slowly dying. The problem doesn't happen at any given time... in fact, I can play a game for 7 hours straight and the monitor won't miss a beat... or I could be working in Photoshop for 5 minutes, and it'll happen. Anybody have a similar experience?
