I leave my HTPC on all the time. I use Harmony remote for all functions. I recently changed my system from AMD proc. and 5770 video card to using only the i5-2405 with integrated graphics. About 50% of the time when I turn on the rest of the system, the picture is letterboxed. I have to get the mouse out, restore down media center and then maximize media center in order for it to display full screen. The other half of the time when I turn on TV and receiver the picture is full screen. What do I need to do to avoid the letterbox problem?
