InFocus X10 Projector: Measurements and Calibration

First here are the measurements "out of the box" for best mode, with lamp at full power. Those settings are Color Temp set to 6500K Gamma set to Film, Brightness to 64, Contrast to 18, Brilliant Color off, Lamp on high, and iris fully open.

Measurements


White (100 IRE)	6422K
Light gray (80 IRE)	6289K
Medium gray (50 IRE)	6192K
Low gray (30 IRE)	6292K

Over all, a little to the warm (reddish) side (lower than the ideal 6500K), but close.

Post Calibration


Brightness	64
Contrast	28
Color Temp	6500
Gamma	Film
Lamp mode	Hi

RGB settings


Gain	R=50G=48 B=49
Offset	R=48G=49 B=49

Gain

R=50G=48

B=49

Offset

R=48G=49

B=49

As you can see, not much to adjust!

OK, remember we're loooking for D65 color which is technically 6480K (most just refer to 6500K as I doubt anyone can see a 20 degree shift in normal content.

Calibration Color accuracy


White (100 IRE)	6514K
Light gray (80 IRE)	6533K
Medium gray (50 IRE)	6593K
Low gray (30 IRE)	6566K

Now those are truly great numbers! Virtually dead on. And they are reflected in the beautiful skin tones and color overall!

I should note that below 30 IRE, where our equipment is less accurate, there is a slight warm shift (lower number) but even at 20 IRE, that was still holding at 6311K.
