Vid card and LCD TV

I have visual challenges and have been using a large screen TV/Moniter as my display. I n control Panel the monitor shows as "Generic Pnp Monitor" and in the Nvidia Control panel it is a "Viewsonic N2752w". My delema is as such, what ever I tend to look at is very degraded, ex. a word doc or looking at a web page, like Newegg. The images are not sharp AT ALL. This also includes viewing pic's downloaded from a camera.

The Viewsonic specs are;

I have the computer plugged in to the HDMI in on the monitor (and have also tried the VGA out).

Res is set at 1360 X 768 and easy to read at Medium.

The cable between the card and monitor is a Monster Cable SVGA to HDMI.

Is it my Monitor, setup... What?
