Dual monitors flickering, blacking out

diplo · 30 Oct 2013

I've got a built desktop with integrated graphics on the motherboard. It has a DVI output and VGA output, both in use. At first the left screen with flickering a lot right when I booted it up in the morning. I swapped out the cable with a spare thinking it could have been a bad cable (theres nothing around here to cause interference). Still flickering, I swapped it with a spare monitor of the same size. Now the left monitor isn't flickering, but the right one is going completely black occasionally. The monitor is on but the image is black. I updated the Intel HD graphics driver through windows update thinking it was a bad driver but are signs pointing to faulty hardware? Any advice on this problem would be great as it's being quite bothersome.

Edit: I can post a DXDIAG / speccy information later but I can't access the machine at the moment.

Probably, you need to get 1 more working monitor to test.

So far the caveman approach of switching equipment has been working. I haven't had problems with Asus monitors before but they seemed to be the issue. We'll see how it goes with these Hannsg's instead.

So everything`s ok ?

Yes, so far I'm chalking it up to bad monitors. I just so rarely see even one go bad, much less two. They weren't playing nicely together for whatever reason but it's been solved by simply using different ones. Weird problem, but solved.
