[quote=lovingdvd;21328834]Great tip. I confirmed that last night. So although the color temp (I am using Custom 1) and user mode stay the same when you switch the iris between Auto, Manual, and OFF, the pj indeed is maintaining separate RGB gains and offsets accordingly. IOW there is Custom 1 Auto, Custom 1 Manual and Custom 1 OFF (not labeled that way but effectively that's what it is).
IMPORTANT: This means that anyone who calibrated with the iris in manual or Off and is running with Auto, and did not also set the gains with auto engaged, is running with a CT that is likely significantly off.
I am going to read through the VW60 tweakers thread (wow 50 pages, really?) and see what tips I can pick up from there.
Does that mean you are opening it more (brighter, probably) or closing it more (dimmer)? Is there any potential downside from doing this, other than risking running out of headroom (which can be checked)? What do you gain out of this -
higher brightness with same on/off contrast (black level stays the same) and to what extent?[/QUOTE]
That cant be done or can it ?

if you get higher brightness AND the black level stays the same - then the on/off contrast cant be the same, it will better/ bigger, right ?! or am I reading it wrong

? ..... that it is not at the
same time for instance, first a picture with black level at min. ( iris at same Reg closed number, as the fabric setting in the service menu) and then a picture with brightness in it ( with the adjusted more open iris , because off a higher Reg open number then the fabric setting ), but this is with a higher black level floor, correct ( aka same contrast ratio ) ?
Sorry if I messing around in it

, but I too, find it very interesting to play with the iris in the service meny to improve it even more, so Im with you on this
