I keep getting the contrast 100% alarm in mid-screen. I can't shut it off at times and at times it just goes away. I can't seem to re-adjust it to a lower value, it just keeps moving up to 100%? Any tips or others with the same problem?

sounds like some of the components inside the monitor are becoming defective...the fact that you said some times you get a screen for a while then it goes away indicates a component is changing value when power is applied and shutting down the monitor...probably a capacitor in the power supply...best bet is to get a new monitor, as service rates would exceed the cost of a new or used one
This is common problem observed in many monitors compaq,HP,IBM this is happens mainly in rainy season due to moisture,by this moisture monitor botton circuit get rust inside and button pad remain pressed. so it shows a strip at the middle of monitor like contrast or brightness. So this is minor problem just replace the monitor display control button sensor or circuit.It deffinately solves your problem.
most monitors get darker with age -- for a while you can counter this
by turning up the Brightness and Contrast controls, but this only gives
you a little extra time (and probably speeds up the decay process
try disconnecting your network cable and adjust the settings again, if you cant, enter safe mode by pressing f8 in the startup and select safemode then adjust the contrast there.
Or is this in the CRT monitor? inside the monitor? there are no viruses ever made for monitors. So its most likely a hardware fault in the crt. Maybe its time to buy a new one. LCD preferably easyer on your eyes.
This is a problem in the monitor itself. The computer has absolutely no control over the On Screen Display. Most likely the button that controls contrast is stuck. You might try blasting the button with canned air. Sounds like it might be time to buy a new or used monitor.
