I sent him one too, it seems he may be a busy cat?
I was at Mark's house last night calibrating the Vango. Without the EE box in the loop, using the Rec. 709 color space we got 400 lumens pre-calibration and 350 post-calibration.
On his 110" diagonal StudioTek that is 14.5/12.7 fL.
Post-calibration was spot on for gamma, grayscale, and colorimetry, though we had the Lumagen help out substantially with the gamma, which tended to fall off substantially above 50% input. This is, I assume, the source of the great majority of the lumens loss.
It was a very nice image.
We set the machine for the standard width gamut and not the expanded LED gamut. While the gama was set on the Vango at 2.2, the actual measured curve tailed off above 50% and required much correction with substantial light loss. The internal CMS of the Vango was used and not the one in the color box or in the Radiance. Next week we will use the color box for setting the CMS points. This means setting the Ls wide up in the projector and using the bixes CMS to bring them down to the correct point, Ditto for the xy positions. Full instructions are not yet available for the box and we didn't want to screw with doing it there without the coming instructions. Remember the projector has the TI high brightness mode which the box corrects the most obvious color errors. Machine is a lot brighter in the EE maximum brightness mode. Meanwhile I will be happily viewing it tonight at 10 ft laberts dead on everything else and sharp.
