I'm not sure if this is the right forum for this question because there's a good possibility that it is a computer related issue. However, I just purchased a new 55lw5700 and I'm trying to connect my computer to the TV via DVI>HDMI. For whatever reason the TV is not getting a signal from the computer and just displays "No Signal" on the screen. I thought there may be an issue with the HDPC compatibility but before I purchased the LG I had the same computer hooked up to a 32 Phillips LCD with no problems. I've tried updating drivers and and changing the computer back to its native resolution. Any help would be appreciated.
