I have a 4+ year old Benq LCD monitor that just started bugging out today. When i came home from work this afternoon i noticed it was auto-adjusting itself (sets desktop to borders of the physical screen). Now it keeps doing it, sometimes constantly, sometimes every like 5-10 minutes. None of the menu buttons on the monitor are working either, power button has no affect. Only way to turn it off is to unplug it (and this didn't help anything). Screen still looks great, just the annoyance of having the auto adjust going... Is there anything i can do to fix this or is the monitor on its way out?
