Screen adjust changes when entering/leaving full screen games

Well had my monitor for about a year comming up (should be still under warrenty worse case), and recently the screen gets messed up whenever entering or leaving a full screen game.

It moves horizontally to the right everytime i enter/leave a game meaning the whole horzintal position moves, leaving a black edge on the left side and unvisible parts of game/desktop on the right. I can fix by just doing the auto adjust but its annoying to have to do that so many times per day.

Is there any fix or reason this is happening? thanks.
