I got the exact same problems with my 2nd Gen. Xenarc MDT X7000 ... But am getting used to it :wacko:
I had an issue when the computer turns-off the screen because of in-activity and Xenarc screen won't pick-up the signal when I touch the screen (so I turned off the screen turn-off from the power options and the screen saver options).
I do have the Rear Only audio issue, but I will try to increase or decrease the fade and balance and give it a try ... the first time it happened i was playing around with the audio settings :moony:
apart from that, the screen is doing fine :lol:
