Blu ray, DVD etc color is YCbCr which has a native data range of 16-235. The only reason you would calibrate wider would be if you were using RGB source (i.e. computer graphics) or perhaps
a notch or two of headroom above white (i.e.236, 237) to safeguard specular highlights. Many devices allow for sending extended rather than normal range but on those sources there's nothing there. I guess Theta isn't expecting people to couple a computer graphics application through it.
This is a fairly complicated subject and shortly i will have some more info for you related to how the range is defined by Theta but Mr Kale has said it quite well.
Your Calibrator seemed to make a gesture that Blu Ray uses colors outside the 16-235 range and from what I understand he is wrong..
Standard HDMI spec is defined as 16-235 as I know it. This also applies to everything we have that is hooked up to a Tv/Projector like Xbox, Blu Ray etc.. There is something related to PC that can use the range outside the 16-235 but i am not sure it helps anyone.
The Cb3HD HDMI board is capable of pretty much whatever we want it to do but as AV Receivers (Ie. Denon, Yamaha Etc.) and I think every one else in the video switching business including Pre amps, they are all keeping with the spec of 16-235.
I have this strange feeling that if the Switcher was set to full range, i think you would have problems and that is most likely why Theta and Everyone else has chosen to use the 16-235 industry standard..
Keep in mind that Blu Ray says that is puts all colors in the 16-235 range and this is something that got me confused when Mr Abrams Your calibrator made it sound like you would not be getting the best picture through your Cb3HD.
I can assure you you are getting the best picture !!
We are going to do a little digging but you can ask Mr Abrams what he thinks about what myself and Mr Kale are writing.
Ps.. The Cb3HD Video card is flexible and can do other things but i think the designers set it to industry spec.
