I know how to enter but not what and where.
I know the x and y for the primaries as others have measured it before.
I want to enter the cd/m^2 i receive from each color in every IRE.

Using the RGB option seems to be the best but it just puts the dot relative to the reference triangle and not the primaries I entered.
XYZ is irrelevant regardless of what you enter
and xyY is just coordinates that I don't have.

I am currently trying to find a way to calculate xyY from cd/m^2 and xy of the primaries and hope that will help.

Sweet.
My calculations seems to work just fine using the primaries someone measured of an M8500 and a lux meter.

x 0.351
y 0.315
Y 134 (lux)
Which seems to be right as the image seemed yellow/red running the pj without a source.

R 40 lux
G 86 lux
B 8 lux

the cd/m2 was a little low from the bedsheet I use for screen so I might as well use lux as I am not really calibrating for a screen right now.
