Several people have asked me about the problems they are having getting the correct brightness levels on the Sanyo displays. After looking at several different displays, I have concluded that the samples we are receiving from MFG are "RAW" units. As in they have not had the Black Level adjusted, and they have not been white tracked per Atari specifications. I recommend that on all future MTO's the requester specifies on the MTO that the displays need to be set-up prior to delivery to Engineering. It is important that the displays used in game development represent the actual displays that will be used in the product build so that the correct RGB signal levels can be set via the bias resistors on the video output circuits. It is very hard to set the Black Level on the displays once they are mounted in the cabinet, so the best I have been able to do on the field test, and show games is bump up the low end of the RGB outputs of the displays to compensate for the loss in the brightness range. Your cooperation in this matter is appreciated. RLO
