I was just waking up my computer when all of a sudden my second monitor when blank and said it wasn't receiving a signal. I tried unplugging the hdmi cable and plug it back in and all it would do is re-adjust my main monitor. I check on all my drivers and they are up to date. I had plugged in a new headset to my front panel audio and don't know if that could have anything to do with it. I'm currently running and EVGA GTX 970.
