AOC MONITOR PROBLEM?

So i got white vertical running right and left all the time, i found out its DEMO MODE on, but the problem is: my on-screen buttons are not working properly. AUTO BUTTON doesn't do anything, other three buttons does the same (-, +, and MENU buttons) shows cable selectments from HDMI/DVI/D-SUB. How do i fix... show more So i got white vertical running right and left all the time, i found out its DEMO MODE on, but the problem is: my on-screen buttons are not working properly.
