I have connected my hp latop to my sony 32" HDTV via VGA cable, and sound cable. I tried using my TV as montor. Everything works fine when i use it for browsing and watching movies in normal mode. But when i try playing vedios in full screen mode, I get a msg on my TV "PC No Sync" and this comes once in every 2-3 mins and stays for 2 seconds and the picture comes back again. This happens only when i play movies and make it full screen and it works full screen while browsing and there is no problem on that. Can anyone advice why this happens when i play movies on full screen. Thanks in advance
