Marco,
When making a check from an opened file, the reference data is always XYZ
(or L*a*b*) based, and the source profile is thus L*a*b*/PCS.
A source profile needs/can only to be assigned for the "Quick" test, which
use RGB in the source profile as reference..

If you want to check how your monitor behaves for color-managed
applications
(checking the "monitor profile's internal reliability" as you mentioned)
using the "Quick Test" menu, you should select generic RGB or sRGB as
source
space and your default display profile as the destination profile. In
this
case, the program will use the selected source profile to convert the
source
RGB to the PCS (L*a*b* or XYZ, D50). In the Compare window which opens
after
measurements, the reference is computed according to the source profile.
For a more thorough test, you can make measurements with custom lists of
any
size (you own, from a spreadsheet or word processor, or any CGATS file
like
IDEAlliance IT8.7/4 reference files). When you open a color list
containing
color data in any of the recognized format (spectral, L*a*b*, XYZ, etc.),
this list is converted internally to XYZ. When you make a display check
using this list, using the "PatchTool file" menu, the program directly
uses
XYZ (or L*a*b*) in D50, bypassing any selected source profile. You will
see
that the source profile field shows "L*a*b* / PCS" when doing the actual
measurements.
Hi Danny.
Thank you for your reply, but...I'm still a bit confused. :-)
My original question regarded the use of PatchTool's "Display Check" with
a
custom RGB or Lab list (in CGATS format).
More specifically, when using an RGB list, is it appropriate to use the
active monitor profile as both source and destination in the Display Check
UI?
And, when using a Lab list in Display Check, is it appropriate to use Lab
as
source and the monitor profile as destination?
I'm not clear what to conclude from your explanation regarding these two
specific topics.
Thank you.
