Re: 780 GTX Screens turn off after 5 mins of playing games
If what Sajin directed doesn't work, try using a different output in the rear of the GPU. I've had the same issue where it seemed one of my DVI's was going bust for quite some time, 1-2+ years. Mind you I had tried switching power and video cables, etc. It would come and go till I gave it a shot and switched it to another connector and haven't had an incident since.
