I am getting ready to cal my first projector. I was wondering what patterns are best for a LCD front projector. I have done a led and plasma flat panel before but not a projector. I have a colormunki and CalMan software that I use.
Thanks.

Same patterns.

Colormunki - what? the colorimeter or the spectro. Colorimeter not so good for projector use.

I purchased it from SpectraCal. It is a spectro.

Then it is done with the same patterns ... but realize that when the patterns get dim ... 30% and lower on a projector ... the readings on the munki will be more and more erratic ... at a faster clip.

Don't trust the 10 minute timer. Dark readings will help every 5 minutes or less. Will also have to rely on your eyes more to catch issues on the dark end ... since the meter won't be able to see it.

Is there the same kind of issues when doing the color gamut? Should I do dark readings more often? Also should the auto iris be on or off?
Thanks.

Normally there are no issues with gamut because the patterns are all bright enough. 75% brightness level or more. Auto/dynamic iris things should be shut off.

The 10 min time limit is fine there.
