I can't play on full screen (PC)

[DragonWireFire]

OK, so.'
When I play Skullgirls on PC, the game is windowed. It's just in small window.
When I change window ressolution on bigger number, or on full screen, game is.. It looks like Minecraft.
There's ton of pixels, game graphics is pretty bad.
Is my graphics card bad, or is someone else having this problem?
Because my friend plays Skullgirls on console, he have big TV and he have game on full screen and it looks perfect.

So, where's the problem?

Change your resolution in the options to your monitor's resolution.
