prophetik music Posted October 13, 2008 Share Posted October 13, 2008 likely the resolution for your PC is out of range (too big or too small) for your tv. most tvs can't support the normal resolution for a pc monitor, it's far too big. if it supports 720p, turn your screen res down to like 800x600 and go from there to find the largest possible resolution that is in the correct ratio. btw, this should have been in help and newbies. i'll pm a mod to move it.

phill Posted October 13, 2008 Share Posted October 13, 2008 if it supports 720p, turn your screen res down to like 800x600 why not just pick a proper res like oh...1280×720 or 1920×1080...480i/p, 720i/p and 1080i/p actually mean something.

phill Posted October 14, 2008 Share Posted October 14, 2008 I will point to page 40 of the LG user manual for supported resoltuions. Note that it does not do proper 720 widescreen, instead it goes for the computer compatible widescreen 768. Make sure you select the proper res for both TV and Computer. Most video cards (laptop or PC) do support widescreen res, they however will not show up because your current screen does not support those resolutions. There are of course exceptions but they are becoming rare. Plus most laptops have gone to the widescreen displays anyway. Quote Link to comment Share on other sites More sharing options...
