What kind of PC are you using? What kind of video hardware does it have? Does the PC see the TV? Meaning, does your control panel at least acknowledge that it is connected?
Edit: I just looked at the manual for this TV here
, the manual says "This DVI input terminal is compliant with EIA-861 standard and is not intended for use with personal computers." I don't know about you, but this kind of language never stopped me, so if you go ahead and plug it up you will notice the manual also states "Note:
The DIGITAL IN [DVI] terminal can only be used with 1080i, 480p, or 480i picture signals." So this might greatly limit the resolutions that you can use. You may actually be able to select other resolutions, but they may not all work. Or some may work but not be properly centered, give the kind of aspect ration you want to use, etc. Finally, and something else that might be related to your issue, regarding the DVI, it states "When connecting a Digital Set-Top-Box to DIGITAL-IN, be sure not to select "SKIP" from the INPUT LABEL menu. Failing to do so may result in a distorted display or black out." So check the input label menu and see if it is set to skip the DVI.Edited by LiquidSnake - 3/28/13 at 7:47am
