Ill go ahead and list my specs :p 

Q6600 Intel processor overlocked to 3.38 ghz
4 Gigs of Patriot Gaming Memory, 4-4-4-12 timing
2x EVGA 9800GTX in SLI
HD50 Watercooling kit
EVGA 780i Motherboard.

Currently im using a Vizio VW32L HDTV40A for my monitor, 32 inches. Ive been always using dvi to dvi, with a max resolution sitting at 1366x768, which i really dont like, Id love to be using a higher resolution for gaming

So, I went ahead and bought a HDMI to DVI cable from newegg. Plugged er in, and everything is disgusting looking. Text is super funny, coloring is all wacked up. I tried autoscaling it to 1920x1080 and it doesnt correctly scale. What do i do? :(  Id really like to be able to play at a higher resolution, im a big starcraft 2 player. and it sucks after seeing my friends monitors, and they can see so much more than i can. Thanks in advance guys :)

TV's have less handshaking standards built into them than PC monitors do as the manufacturers tend to assume that the majority of things being plugged in work at set standards such as 768 and 1080i (at the least). PC monitors have more handshaking standards to display at as many levels of resolutions as possible to meet the more expansive needs of a PC.

My friend had the exact same problem, couldn't play at 1080i through the graphics card because graphics cards only output in progressive, not interlaced. So he was relegated to 768p like you seem to be.

This subject is a tricky one, someone may know more than me, but i suspect you're stuck with what you already have my friend.

After reading this I went into my laptops properties and found a tv tuning connection app. ITs not as simple as selecting 1080p in screen resolutions. 1080P comes in many flavors - 1080/24, 1080/30, 1080/60 and you have to find what your tv likes. I use several TV/monitors at work and it has been a challenge to get all of them to work, but they do all work.

I didnt see which OS you are using. Win 7 seems more tolerant of tv monitors than others, but most graphics control panels seem to know how to deal with the issue.

DVI also comes in several flavors and resellers are not always clear on what they are selling you (they sometimes buy the wrong tech too). I cant imagine a DVI-A to HDMI, kind of pointless. So Im sure you have a DVI-D to HDMI cable.

Look for a tv tuning app, check the cables and you will get there

The native resolution for this TV is 1366 x 768.

your main problem is that the native resolution of that TV is only 1366x768

Image Quality on an LCD TV is always best if the resolution of the video card matches the native resolution of the TV. In this case 1366x768.
If for example you run the card at 1920x1080, how and where do the extra pixels get displayed?
The only thing the TV can do is combine two pixels into one every other pixel, or average 3 pixels into two. I don't really know how the TV does this internally, but you get the picture I hope. You can't cram 1920 pixels into a TV that only has room for 1366 (and 1020 into 768)

When I use the DVI to HDMI, it says the native, and recommended resolution is 1920 by 1080, but like i said. When i do that its all over the place. the tv though, on HDMI channel its 1080.

Whats a tv tuner app, is that some kind of program?

Look up the specs for your TV in the documentation or on the Vizio website. The native resolution for this TV is 1366 x 768.
The rest does not matter. 1366 x 768 is the number of pixels of this TV and will give you the best Image Quality for use as a monitor.

I ended up messing with my t.v. (same as yours) and the only res i could find to fit it was a custom one i had to make under my resolution settings. i'm running it at 1360x685 progressive 32 bit. try it out.
