I have two Ultra 60 Sparc machines, and both will only work with one particular monitor that I have. When I attached other monitors to either of the two machines, I see only a blank screen, and when I try to adjust the screen, I will get a message that says: "In Power save mode. Press any key on the keyboard or move mouse" Needless to add that I have tried to move the mouse, press all the keys with no success. One more pertinent information, The machines used to work just fine with these other monitors...Somebody please help!
