I have the DP930 and everytime the screen turns off and turns back on...the screen gets messed up and i have to go through the NaviSet thing again to reconfigure the dimensions. It doesnt completly mess up but the screen gets a little bigger and runs off the monitor. So everytime i have to make it smaller. Does this happen to anyone else? Its a pain to always have to re set the dimensions of the screen so. How do u fix it?
