Hi I just received my sharp lc42xd1e last week and have run the 360 through it at 720p (VGA/Component) with no issues at all. I have since tried a PS3 in 1080p via HDMI and the screen kept restarting after a minutes of play, it would go into standby and then come back on again then restart again. only way to stop this was to put the PS3 into 720p/1080i I thought maybe it was a PS3 issue after reading about black screens and stuff. However I just got my Oppo DV-981HD 1080p Upscaler, and it was doing the same in 1080p mode (after about 10mins of playback) I double checked the settings on the oppo and set it to auto nstc/pal switching and video "mode 2" and its still the same. Set it to 720p and its fine. im guessing maybe its the screen settings for the HDMI, anyone else had this problem?
