HDMI looks VERY bad, any help?

[Exactly 9001]

My card is an HD 6750, my monitor is a limited edition Sylvania LC225SSX 22 inch monitor, if any of that stuff matters. I heard changing the HDMI channel to "PC" can solve that problem, but I have no idea how to do that, and I also don't have my remote and I looked through settings and couldn't find anything to change that. My monitor's also 720p. VGA looks perfect, if I use the HDMI cords for anything else, it still looks perfect, it just looks bad when it's connected to my PC. It makes the text all fuzzy and I get "jaggies" everywhere.

why don't you try DVI?

My monitor has no DVI ports, sadly.
