The monitor has four buttons in the middle... One points up, one down and the other two toward the opposite sides...
When I click on the top one I get a box for contrast, color, rotation, etc... If I use the buttons that point to the sides then the ther various parts of the menus are highlighted... Kinda like a clock hand... I can get it to the "rotation" icon but then can't find any combination that flips it...
I've tried the the right click and can't find anything in there that is related to the screen???
