I have a Home theater PC setup connected to a Sharp 32 inch LC-32PD5X LCD TV.

I have spent some time trying to get a 1 to 1 pixel mapping at the native resolution of 1366 by 768 but have made little progress.

I have played around with the tool PowerStrip and have tried some obvious things (ie creating a new setup at 1366x768 at 50hz / 60hz) but no luck.

The best I can do is run the TV at 1280 by 720. This looks ok for things like watching TV, DVD etc but results in what I would call "messy" fonts in Windows because the TV is converting pixels from 1280 by 720 to 1366 by 768.

I've read that 1366 by 768 is a pretend high definition mode that some TV manufacturers use to reduce costs. Maybe this is just asking to much for a cheaper TV to do.

Overall, the TV is good enough for my needs, so just buying a proper 1080p TV is not an option (for a few years at least).

Can't you change resolution from Windows natively? Try doing this using the latest video card drivers. I've also had issues with my TV, but with overscan. – alex Dec 18 '09 at 6:29
    
1366x768 is a dairly common resolution for 16:10 widescreens. – Journeyman Geek Jul 26 '11 at 3:29

Please check your graphics card drivers and update them if necessary.

I've also a TV with 1366x768 and I'm able to set the TV resolution to 1360x768 (Windows and Linux) (I don't know why I lose 6 pixels, but hack, I don't care either). Also, the TV might be falsely recognized as generic or different model, so please check that, too.

Probably you need to set the picture size mode of your TV to something like "just scan". TVs normally work in overscan mode: the picture is resized to some value above 100% to cut off invisible areas and borders.

Maybe your TV does not support "just scan".
