Martin E. – Some people have had problems with TCONFIG, maybe for just the reasons you mentioned, ie: they tried turning Gamma below 1.0 TMODE 11 6 works and uses the default setting. Your gamma correction of 2.10 seems like its in the correct range for RGB, you might want to boost it to 2.2 for NTSC output. Try using TMODE 11 6 alone and if your rendered image looks the same with the Gamma correction you've already set in R3, I would say you're speculation is correct. I'm getting excellent results with whatever the default is. My intention was to provide a working solution until there is a definitive answer from Truevision, which I hope will be today. -JE
