I've been searching for a couple weeks for a solution to my problem with no luck. I am currently using a HTPC running windows 7 64 bit with a gtx 460 card which is feeding an Onkyo tx-nr709 that feeds to my Optoma HD20. I use xbmc for all my media and not all the time but about half of the time when I play a movie the whole image will shift to the left about 5% or so. Can no longer see the first row of icons on the screen and there is a black bar on the right of the screen. It will also do this when on Youtube sometimes. The only way I can get it back to full screen is to put the computer into sleep and wake it back up. Thank you for any help.
