OK, Starting a couple hours ago one of my two monitors randomly black out.
The Screen that blacks out is my Primary screen that is attached with HDMI while the other is DVI. The black outs lasts for a second or two and it also cuts out the sound that i have assigned to play through the monitor however the secondary screen doesn't black out and the other sounds still plays through. I upgraded my video card to at Geforce GTX 970 last year so I'm hoping its not that.
Can anyone shed some light for me please.
