Actually I have not. Its ones and zeros. No video cards, no additional processing. As far as I know, DirecTV boxes do not color what they get from the NIC or external storage sources. No offense but i know far more about this stuff than you do. Its a requirement for what i do. A HDTV wants to receive a YCbPr signal? Really??? List one display manufacturer that explicitly requires their equipment receive a YCbPr signal. All DirecTV boxes send out an 8 bit signal. That is true for those sending 4:4:4 and RGB. Get an analyzer and see for yourself. Almost all displays are capable of recognizing RGB and YCbPr signal types without the end user having to do anything. Accupel is a Chromapure product and has been for a few years now. I know the owner, Tom, quite well and he is always in contact with the original owner and programmer of Accupel pattern generators, Greg. Neither have ever stated that any Accupel has issues with their digital outputs You know nothing of this field so I suggest you read more on what meters are defined as reference. Photo Research is the defacto brand use to calibrate displays in Hollywood and broadcast studios. There isn't one studio that would allow you to touch any of their mastering displays without you having a Photo Research meter. Not one. From one vendor? Sure. I don't use that vendor's tables Wrong. I, as well as many other calibrators, do not put quantity over quality. Guaranteed to fail. The largest difference between my Klein and the PR-655 its tables were created from is <1 dEuv on grayscale and <1.2 dE2000 on color for plasma, ccfl LCD and LED LCD. Translation for normal folks... visually imperceivable. How many Kleins have you used? Better yet, how many spectros have you used?
