To All, I'm trying to set the gamma correction values in 3D Studio for the PAR. I've read the books, I've set the gamma for my computer moniter. When trying trying to set the gamma for the "frame buffer" the dialog box is visible on the computer display. How do I set it on the NTSC moniter if I can't see it. Thanks, Scott

Scott: >> I'm trying to set the gamma correction values in 3D Studio for the PAR. << The gamma setting which you want to mess around with is for file output gamma when calibrating output to the PAR. The framebuffer gamma will have no effect at all unless you have one installed in addition to your PAR board. For my PAR output I have been using an output gamma setting of 1.4 with good results. – Bob Ritger

Robert, Thanks for the reply. Now that you got me looking in the right direction, I should be able to adjust it properly. Thank you, Scott

Scott Theres a file in the library (Gamma.zip?) that is a 50% grey on one side and a grey made of tiny black and white dots on the other. If my understanding of gamma corection is correct only the grey is changed by the gamma setting not the black and white dots. Therefore if one outputs the file from the PAR to video after applying a variety of gamma settings to it in 3ds and views it on a video monitor ( not the computer monitor) the variation that shows the two sides as the same grey should be the one with the correct gamma setting.

Edward, That's what I need, I'll look for the file and give it a try. Thank you, Scott
