I no longer have the spyder software. Currently I use colorchecker plus from
Calibrite.
This software wanted me to change the brightness quite a bit. That was because
it was targeting 120 cdm2. However I left the monitors brightness at 75%. The
120 target required brightness setting to be around 19%, which felt wrong. So I
left the cdm2 value at the measured 220 (the 75% default monitor brightness
setting) and went ahead with the calibration.
Perhaps just ignore the brightness adjustment setting recommended, adjust the
monitors to what seems the same brightness to you, at a level you like working
at. Then continue the calibration. It should come up with the correct profile.
I have read that using a low brightness setting can also decrease the colors it
can display. IE. In this note: https://www.dpreview.com/forums/thread/4467911
someone also says "The brightness of your monitor should be irrelevant when
editing for electronic distribution in sRGB format."
If you are going for print, then a lower cdm2 might be preferred. But for
online display, set the monitor brightness to what you like to work with, then
continue the calibration.
I have Dell monitors which also have various settings. I use Standard. I have
tried Paper and there is also a Color Temp, Movie, multimedia, Game, sRGB,
Custom Color. What monitor are you trying to calibrate?
