regarding undersaturation of the standard color profile at RS55/65/X70/X90:
I could get RGBCMY closer to the Rec709 targets (in normal lamp mode) by a little service menu tweak.
There, profile preset "standard" has a parameter named "L2", set to 5 as factory default.
I set it to 4 because this seems to be in association to color profile "Cinema 2".
With this, profile "standard" gots a little bit larger color space (not much, but visible).
For the cube 3 can be better (that's "Cinema 1" with larger color space).
To get it active I had to close the service menu and switch to any other than the standard and back to it.
But do not switch to color preset "off", cause there is a FW bug - if you change back from "off" to "standard", the low end grayscale gots a bit shifted..Edited by *Harry* - 9/28/12 at 12:47pm
