Magnavox LCD TV used as Monitor has grid of pixels and text is bitty/pixelated and I can see the pixel grid

[geigmeister]

I have a Magnavox LCD TV, Model Number: 32MV304X/F7. I'm using a desktop PC on Windows 7 Home Premium 64 bit.
Here's the specs: https://www.magnavox.com/en/products/129-32mv304xf7.html
No matter what settings I do or screen resolution, the text looks very pixelated and i can see the pixel grid. I don't know if I'm just supposed to sit farther away or something, but here's my graphics card if it helps:
AMD Radeon HD 7800 Series
It has capabilities to run Pandora, Netflix, Vudu, and Youtube through the TV interface but I mostly notice the problems when I'm using my PC.

Whats the max resolution you can set it too? Because when i look up that TV it says its max res is 1360x768 which is very small for that size of a TV, meaning it would look very pixelated.
