I seem to be having the same problem setting the gamma on my
Targa+. I'm running through a T+ 16/32 straight to an NTSC monitor
via S-video. The Targa Gamma is set to 1.0 via "tconfig". I couldn't
get the color swatches to come even close. The outer box was much
darker than the inside, and it also gives off an annoying moire
pattern. After reading the notes here, I tried adjusting the
brightness and contrast controls to get the grays to match, (they
still don't, but they're closer) with the gamma set to 2.1. I did this
in the Mat editor and left the display at 1.8 (a perfect gray match!)
and rendered some materials on both the display and the Targa. The
samples appear dark and kind of muddy on both displays, but they do
match, however… I loaded several JPEGs off the CD (view image) and
they ALL apear much to dark.
I've reverted to what I was doing, which is seting the Targa
gamma to 2.1 in 3ds and then setting the monitor's bright/contrast so
that the cd sample images look their best.
My display gamma is still set to 1.8, which seems to be the
best by matching the gray squares, but sample materials rendered on
the display still seem much to dark.
