blurry and unsharp image with VGA

I'm not trolling or anything but I compared the xbox 360 against the pc and the xbox 360 graphics are very blurry and unsharp. I cant even play on the xbox because my eyes starts to hurt after 10 minutes. Anything in the distance is just a big washed out blur. Multiplayer games are a joke because i cant even play a full match without tearing my eyes out :p

I played around with the reference levels but that did not solve anything. Im using a third party vga cable (logic3) but I doubt that the cable is causing it. Or is it the game that is not made for 1920x1080? I have no idea.

Is this normal when using VGA?

I have set up 2 instances of mw2 at the same time next to eachother.
Below are a few samples of my problem:

The xbox 360, when outputting "1080p" is actually just taking the 1280x720 image (native) from the game and upscaling it to 1080. So really the xbox only supports 720p and the upscaling is what's making the image look bad. You could either change the system's output to 720p and try letting the monitor do the scaling instead of the xbox, or just accept the fact that console systems will never be quite as sharp as PCs.

Reference levels have nothing to do with the resolution or blurriness of the picture, rather, the color saturation/ contrast output of the system. Keep these at expanded at all times if using with a monitor. I can tell from the pictures you posted that you are indeed just noticing the lower resolution. Try setting your PC to 720p and compare the games then. You'll likely see a very similar blurring effect.

Use DVI
