I can't get my Vista Media centre PC to perfectly 1-1 pixel map to my TV.

I'm using an HD4350 graphics card with onboard HDMI, and if I set it to any kind of 1080p resolution it wont fit properly. It starts off too small and using the scaling options in Catalyst Control Centre (CCC), I can get it to fit either the height or the width, but not both, unless I use some kind of weird, user defined, resolution. I either get part of the top and bottom of the screen missing if the width is correct, or I get black bars down the left and right if the height is correct.

No amount of playing around with the CCC settings are any help and the TV is cheap and has very limited configuration functionality. It does work at 1080p with a PS3 though, so it's not that the TV is faulty, it just doesn't work with PCs. There is some kind of option on more expensive TVs so I have heard that forces the HDMI signal to cope with a PC's output, but was wondering if anyone else had any other ideas as I seem to be limited to software options.

It was the same on all three 1080p tv's i've had, two Samsungs and one Sharp. Also using Nvidia and ATi graphics. On the Nvidia you can do the arrow thing and bring the edges in but like you say it goes from 1920x1080 to something like 1776 x 1054 which isn't cool at all.

Saspro might know though, he knows lots about Media stuff.

Yeah it's 1:1 pixel mapping over HDMI or something like that.

I googled and found this article

cheap, 1080p, where did you find this TV?

I'm not looking I'm just curious. My 720 projector is doing me just fine

Ebuyer for £500 at 42", however, I initially ordered a 32" panel for £300, and when I returned it, I asked to upgrade it to another panel and they said that they had already sourced a replacement, as they no longer sold the TV I had bought. It turned out to be this larger panel which cost significantly more.

I've got a 4550 that does it. I had to manually create the resolution for it to work.
hdmi loves to overscan. Not sure why manufacturers don't disable that on flat screens.
Also try setting the refresh rate to 59Hz instead of 60Hz

I managed to fluke it completly when I bought a new TV & PC, as I knew nothing about pixel mapping at the time.

I got a 37"LG LF66 TV, which works perfectly with my PC with pixel mapping. Its probably been replaced a couple times by LG now, but im sure their newer models probably have it as well.
