Re: Help! Monitor distortion
Such distortion are often the result of either bad synchronization or bad HDCP handshake.
I'm afraid there is not much you can do against that.
Check if there would be any firmware update for either the graphic card or the monitor (rare) and check your video idle settings. Maybe the way your card goes to sleep/sends blank screen can do a difference?
