Open your Config.wtf file located in WTF folder. Delete its contents and paste these lines:

SET gxWindow "1"
SET gxMaximize "1"
SET gxResolution "2560x1440"

Save it and try again. If problem continues, remove the gxMaximize line or set it to "0".
You might wanna clean install your graphics driver.
