I am pretty computer illiterate and I need help!!  When I'm on FB I play a lot of game apps. When the games start part of the display is off to one side and it cuts off the buttons to make things larger or smaller,the mute etc..  I have done everything I can to fix this problem. (which it did fix for a few hours and then went back to sideway again) I can not figure out what I did to fix problem! I would appreciate any help I can get!!
