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.
