I don't think the AutoCal really works for anybody except Derek Smith in the introduction video. :D At least I don't know any trusted professionals who reported success. But I tried it only one time myself and didn't read forum reports about this since monts, so may be it's improved with new VT30 firmwares and CalMan versions. I think the sensor version is the easier question: You can use the OEM i1d3 with more third-party softwares (ArgyllCMS + both CalMan and ChromaPure). The OEM i1d3 miss the X-Rite software only but I think it's easy to let go when you can use ArgyllCMS (I think you would use ArgyllCMS for PC displays anyway...) And it's cheaper to buy as a meter+software (CM or CP) combo. As of the software: I would pick CalMan for the best compatibility. CalMan supports more sensors (retail and OEM) and devices (like you sad, Panasonic AutCal and some external video processors, etc - even if it's practically useless for you right now...). And it's perfect to carry out a basic "ISF-like" HDTV calibration (both CalMan and ChromaPure is practically useless for anything else, no edge on either sides - just my opinion...). 2012/1/26 Kristian Jörg <krjg@xxxxxxx>: > The Calman option would give me the possibility to use autocal with my > Panasonic VT30 plasma, i.e calman can remote control the TV and > automatically do a high quality calibration with a final result of deltaE < > 3 (configurable).
