We are installing 7970's in residential environments, and would like the customers to be able to switch the backlight off, but there seems to be no way to do this aside from a timeout.
It seems like the on time should turn the backlight on, and it should stay on until the on duration expires, then it should go off after the backlight timeout. This way you could have it on during daylight hours, but would automatically turn off at night unless there is activity, in which case it would begin a timeout cycle, and then extinguish.
The way it presently seems to work is the timeout duration is honored even during the on times! This is rather useless!
Is this bug going to be fixed? It would also be nice if the backlight control button could simply be pressed by the end user to kill the light anytime. This could be also a useful feature for privacy.
