Seems to work, thanks! Donation is underway :) It's really unfortunate
that I made the purchase uninformed, without digging into ArgyllCMS
list archive. Had I known that ArgyllCMS beta has Spyder3 support, I
certainly would have purchased not Elite but standard version and donated
the balance to ArgyllCMS. Sigh..
I'm trying to get rid of strong brown cast, the black point after monitor
reset is off ~25 dE. Seems that I can get rid of it by adjusting RGB bias,
but having hell of a time because the reading is randomly fluctuating
around +-4 dE. Not to mention that adjusting WP throws black point off
again.. Black point reading is very slow also, but for a reason I guess.
Any hints how to accomplish this task and for what black point dE to shoot
for?
