I bought a new Sony Bravia 32" HDTV (KDL 32S5500U) - HD Ready (720P). I conneced my hp laptop to HDTV via VGA. I think the resolution adjusted itself when i made it as my second screen and everything works fine (Both Audio and Video). But when i play movies from harddisk (Any player - vlc, media center....) or from youtube ON FULLSCREEN, i get a error PC No sync every 2 mins and that stays only for a sec or 2 and then the display comes back. This happens only when i make it full screen and nothing happens when i browse. This happenes only when i play vedios and make it full screen. Anyone please help... No solution on any forum... Stressed with it for last 5 days.
