How do I fix this

When I enter the game most the screen is black and the game only shows on left top side. I took a pic. Please help.

 

What is the resolution of your screen?
Does this happen every time you launch the game?

 

Happens in Windows mode as well. And my resolution is 1600x900 which worked fine in games campus

 

Try changing your screen resolution to 1280x720.

Does this issue happen in any other games?

 

The resolution didn't work and it happens with every game. Also I forgot to mention, in the black screen I can click all the icons where they are suppose to be like "my info" and "lobby". It's just projected on the top left

 

Try changing your windows scale settings to 100%.
