Scott,

Just an off the wall suggestion but have you thought about putting some
"neutral density" material over the display when you need it to be/stay
really low?

If you have a full-service camera store in your area, stop in and tell them
about your S-Tec display. Tell them you need some 2-stop (dark) and/or
4-stop (really dark) neutral density gel (aka...ND) and see if they can help
you out.

A couple of small pieces of the good cloth duct tape (not the silver plastic
stuff), a rectangle of the ND and "Bob's yer uncle."

Like I said, just an off the wall idea.

HTH,
