I just wanted to take a peek at it and its chromatic values so I can create FW900 profile for my HP DreamColor Gamut correction is so nice it will correct all colors inside what your monitor can display. There will be some clipping if requested color is outside monitor gamut but for videos this should almost never happen as colors are usually more toned down and even if it do happen it is not really noticeable. Even if chromatic point of one of three primary colors is shifted slightly eg. green and have different hue and/or saturation then hue of almost all colors (if they have any green in them) will be affected, not only green. For FW900 and other Trinitrons the gamut error is small but definitely visible because it is also in green and we are most sensitive to green. Older videos should look fine on Trinitrons but from what I remember it isn't perfect match with Rec. 601 either (will compare it now ) and besides video player will detect video type and automatically correct colors so it is pretty automatic. I recommend using madVR for video playback. Other than great color correction is the only video renderer that have zero issues with perfect synchronization of videos to display and its upscaling capabilities are awesome. If you have not already give it a try. Many other players also have color correction including MPC-BE with which I use madVR.
