Terrible quality when using my HDTV on my PC.

[pb7280]

I have my 42" Sharp LCD pugged into my computer, the TV is 1080p and the resolution is set to 1920x1080, yet there are black borders around the screen about an inch thick. and the picture is like all fuzzy which you could imagine would happen when a 1920x1080 picture is displayed on an area thats smaller than that. The TV is plugged into my computer through an HDMI cable, that is plugged into a DisplayPort through a DisplayPort to HDMI adapter that came with my Alienware laptop.

Specs:
Microsoft Windows 7 Professional x64
AMD Phenom II 940 (X4 3.0GHz)
ATI Radeon HD 5870 1GB
OCZ FATL1TY RAM 4GB 1066MHz DDR2
3 x 500GB RAID0
ASUS M4A78 PRO Motherboard
Corsair 750w PSU

Thanks for anyone who can help.

Could be the adapter. Or could be a driver issue. Don't you have an HDMI output in your 5870?

HDMI output is going to my monitor, but I could try switching them. Also the newest drivers are there, they release new ones about halfway through every month so should be soon.

I believe you will need to adjust the overscan settings in CCC to make the picture properly fit the screen.

I plugged it straight into the HDMI port, nothing changes. I'll try the overscan.

OK, adjusting the overscan fixed the black bar problem, but the quality is still absolutely terrible.

How does it look when actually plugged into the HDMI port?

It looks the same plugged into the HDMI port, does it mean there's something wrong with my TV if it needs to be adjusted like this? Like is it not actually 1920x1080?

I've heard of other people having similar picture quality problems through HDMI from PC to TV. I think it has something to do with the "content protection"(aka DRM) built into the HDMI format and varies from tv to tv. Do some googling and try to see if other people have complained about similar problems with your television and perhaps have found a solution. I believe often using DVI instead clears it right up. DVI does not carry sound but it also lacks the DRM of the HDMI format.

I'll live with it my TV doesn't have DVI plus i need the sound.
