No, its the HR24-500 that has RGB colorspace. All the rest have YCrCb. RGB colorspace isnt to be confused with the analog RGB outputs. Y′CbCr is not an absolute color space; rather, it is a way of encoding RGB information. The actual color displayed depends on the actual RGB primaries used to display the signal. Therefore a value expressed as Y′CbCr is predictable only if standard RGB primary chromaticities are used. An RGB color space is any additive color space based on the RGB color model. A particular RGB color space is defined by the three chromaticities of the red, green, and blue additive primaries, and can produce any chromaticity that is the triangle defined by those primary colors. They both produce the same results, but I believe the RGB colorspace in digital has a black level higher than 0, so YCrCb might be able to produce a few more colors? Not sure on that. Most of my higher end video equipment uses YCrCb, but the cheaper stuff (FTA satellite receiver for example) also uses RGB. My video processor converts it all to YCrCb before sending it to the monitor. As for the video cards, there are two signals present, DVId and DVIa on the same connector. One is analog, one digital. If you had a straight DVI-D video card, the DVI to RGB adapters would not work on them.
