I've had issues ever since these drivers on my multi monitor system where not all my monitors want to wake up from sleep. I have to sign out for all the monitors to come back on again. Edit: Fixed.. I had to uncheck all my DSR options in NCP. Looks like my monitors were attempting to display a resolution it couldn't.. The light would come on like they awoke from sleep but the display was blank.. Disabling all DSR scales fixed it..
