Question: if I don't want to use the "PC" port on my TV, shouldn't a regular DVI to HDMI cable do the trick? I might have some overscan, but it should work, right?

Currently I'm not able to do this. I have the PC hooked up, but the TV isn't detecting an input at all, let alone a bad looking one. I connected it back to the VGA port, and I can see the screen but it displays with a thick black border on all sides.

Just to be sure, I've set it to 1920x1080, and the refresh rate is at 60Hz. That's all I should have to do, right? Any ideas why it isn't working at all?
