Have fun
unless someone needs the info most have no business fooling with it and those that do know the sm codes.
As long as you write down the original parameters before you change anything, I don't see how you could mess anything up. It's not like you're changing any voltage settings within the display where there's a possibility of burning it up. It's mostly color and black level parameters.
This would give your calibration software a whole new dimension.
Another aspect of the SM I like is being able to change V and H settings. On my particular set the "HD size 1" is just a tad inset(by just 1 white line on each side) on the horizontal so I use "HD size 2" which blows the picture up a little too much for me.
It also show exact hours on the display so if you're doing the "break-in" procedure, you know how many hours are on the set instead of just guessing or logging run times.
