My monitor's having some problems. The menu just pops up randomly and I'm not even touching the buttons on the monitor. It's like somebody's controlling it. But it doesn't even have a virus. I looked at a manual and it said nothing about this problem. And sometimes the buttons don't do what they do. Like when I press "menu" it exits out, but when I press the "exit" button, it doesn't even work. I have been having this problem as of late. Of course, the monitor doesn't have a virus.
