mhhh - we have grayscale video - that was not possible due to hardware limitations,too - until....

does somebody know, at which rate the led`s of the display can be switched on/off?
maybe dimming could be done by switching the display on/off very quickly - by software.

sorry - maybe this has been discussed already, but i missed the thread and didn`t find it in the archive.

at least, there have been recorders out there which were able to dim (i saw a videoclip somebody posted on this list). do we know
that was a hardware or a software-based dimming?
if it was software based dimming caused by a "developers firmware" accidentally escaped into the "wild".......?
