I could understand it outputting PC levels if you have mirroring selected but there is a Rec709 colorspace and it seems odd that Apple would leave the Mac outputting PC levels with mirroring turned...

^^ Well said Manni.

We know JVC can do great stuff. Sadly, we all know they can goof it up too, as Manni stated. There are more examples of screw-ups and of innovative well implemented designs,...

No way I'm buying a first chassis JVC. Got bit in the ass doing that with the RS50. Never again.

I have no inside knowledge but I have to wonder if we'll see any new innovative JVC projectors....

Tom and others are more qualified to answer this but I think generally one uses the same gamma targets for all stimulus levels except when calibrating to BT1886. That said, at times I've calibrated...

Gamma affects saturation, hue, and brightness -- for example, saturation increases as gamma is raised and it's one of the reasons some folks prefer a higher gamma.

I'll let others answer questions 1 & 3 but as for question 2.....Gamma is calculated from the 100% reading. So yes, gamma readings are sensitive (dependent upon) the 100% reading.

Tom,

What is the build number of this latest build? I removed 2.5.5.38xxx and downloaded 2.5.5.190. It seems like this should be an earlier build but that makes no sense???

Got to be a big relief to have it working.
Did something in the HDMI chain change since you last used the '57 (or was this the first time you fired it up)?
