Intel HD3000 HDMI to TV not working

I have been using my gaming rig to stream movies off of my server to a plasma TV. To cut the wattage and brutal way that the gaming system heats up my entertainment room, I opted to use a laptop that I seldom use, an Asus K53E on Intel HD3000 with an HDMI output. When I did the swap, the laptop immediately detected the television but despite my best efforts, I can not actually achieve picture or sound.

I have used the same cable, and verified it again from both my gaming rig as well as from a Wii. I have also tried an alternate, higher end cable to the same result. I've tried selecting HDMI via the Intel graphics control panel and by using the Fn + F8 hotkey to no avail. I've checked the BIOS and have found no settings that refer to video handling. I've verified that I am on the latest Intel driver set from ASUS, tried reinstalling it, and even tried the vanilla Intel driver straight from Intel.

I have NOT had an opportunity to test the port with another display, but thought I'd check to see if anyone's had a similar issue before I go hunting for someone else with an HDMI display to test further on.
