I'll play around with it sometime, probably on one of my other 12" displays first so I can make sure I know exactly what each does. When I get around to this I'll make note of what does what and make a diagram for anyone interested.

One other question, though--what would make the display come out of focus? I'm guessing just age, maybe inactivity? Aside from the focus there are no other problems--the color is good, no burn-in, hasn't been used excessively (I'm the original owner and know about how much time has been logged on this display).

(I do have another 12" that works perfectly in poor cosmetic condition that I can take parts from if need be).
