I just spent a day on this, so I must share. I am using a Panasonic TC-L32U3 as a monitor for my PC. Yes it has issues, but for $300 I have 32" of 1080p great for media and gaming.

Problem: Like some TV's the Panasonic will not display full HD through it's DVI port. I ran a DVI to HDMI cable. However, when HDMI is used the "PC Adjustment" settings on the TV are disabled. In 1080p I was left with a signal with 10% black lines surrounding the screen.

Preparation:
1.) Check your TV options. On mine there is HD size 1 (which crops to 95% to eliminate digital broadcast noise) and there is HD size 2 (full screen). Obviously we want full.
2.)Label your inputs as monitor, computer, PC, or similar. Many TV's software enable features based on input selection.

Fix:
1.) The problem is with your graphic card's overscan/underscan setup. Either attempt to use Nvidia control or ATI's Catalyst Control Center to change the setting.
2.) #1 did not work for me. I installed the latest ATI CCC for 64 bit Windows, but it had limited functionality. I tried old versions, staying up until 2 in the morning. 10 minutes ago I finally found this:

I zeroed out the registry key as shown, and am now full screen. Good luck.
