Hello admins/Gms etc

i got this problem.. that i can only use the lowest resolution
if choosing a higher Resolution, it kinda goes outta my screen..

Hope you guys can help me out. kinda freaks me out in PK
that i am only capable of seeing the game in a very low resolution
my PC resolution is 1366x768..
i have been trying to change my pc resolution when getting into the game
but wasn't affective in any ways.

I just tried that, but gave the same result as the picture you see
it just keeps jumping outta my screen.
