I have been trying to connect my Proscan (37LB30QD) to my Desktop PC for a couple of days now. When the HDMI cable is plugged into my PC from my TV, the computer detects it and lets me adjust the resolution. I do not get any video showing on my TV though. It just keeps saying " No Signal ".

Below is all the information that I know about my system.

Issue Details
Connecting LCD TV to PC via HDMI. No video at TV. Windows detects TV and allows me to adjust properties. I set it to "extended desktop" and the click "apply". The screen goes black and comes back up, still no video to TV. If I remove my VGA from the monitor and plug it into the TV I get video. I don't want that, I want to connect it for good and extend the desktop

TV is set to HDMI-2 (works with FIOS box already) and I have checked the cords and they are connected and in good conditon
