My HP 1702 has a blue box in the upper left corner .
Line one says 'AMP 2'
Line two says 'PER 4.0'
Line three says 'Exit'
and it keeps flickering between all three lines. If I press the 'menu' button it will stop flickering with just one option highlighted but even if I can get it to stop on the 'Exit' option I cant get it to exit.
Sometimes when the monitor has been unplugged for a while it will start with no menu up but eventually it will pop up,
Any idea what that menu is?
