Paul, >> It seems difficult to get a "clean" looking white white these lower luminance levels… << Take a look at some SMPTE color bars and look at white and 100% white. The white I'm suggesting is white although its not as intense as 100% white. Depending on how much of the screen is 100% white, you may or may not get complaints, that partially depends on whether its broadcast and the editor you're working with. 235 is the Max RGB value you can use in component. In the digital relm there is only 220 discrete levels for contrast without causing banding. There are several ways to handle it, one of which is to have an algorithm interpolate the pixel values to bring them within range. I choose to lower my luminance level and work from 7.5 IRE black as my baseline. Then during the conversion from RGB to YUV I'm staying within the discrete range of possible pixel values with no interpolation. 210 is close to white, where 220 would be 100% white. John BTW I haven't heard anything on the Targa drivers yet. Its a rough go for Truevision, the parent company seems to be rather myopic.
