Thanks Stephen,

I have calibrated an inexpensive TN LCD panel and an older CRT with the
Spyder 2 so far.   I'm not too impressed with it.  I also have an I1-2 which
I think my kids have pilfered which seemed to work better.

I wonder if it's possible to get replacement filters for the Spyder2.    It
is an older device, so it probably is not worth the effort, and definitely
not worth having calibrated (if it's even possible).

The device seems to respond to dispcal attempting to read ambient light
which is why I asked my original question about ambient.   When I get my i1
display 2 back, I'll get that ability back.
