HT Labs Measures

Black: 0.002
White: 17.2

Full-On/Full-Off Contrast Ratio: 8,600:1

All the measurements here were taken through an HDMI input with the projector adjusted for the most accurate picture in a darkened room.

These measurements were taken on a 100-inch-wide Stewart Filmscreen StudioTek 100 unity-gain screen. If you multiply the black and peak-white levels above by 1.3, you’ll get a sense of what they would be on a 1.3-gain StudioTek 130 of the same size.

The 6500K color-temp setting was very close to correct and very consistent across the brightness range, reading only slightly deficient in red. When I calibrated 30 and 80 IRE with Brilliant Color off, I got the gray scale spot on except at the very low end, which went slightly red. I tried to compensate for this, but the rest of the gray scale wasn’t as good.

Before I enabled Brilliant Color and recalibrated it, I measured the color gamut and found it to be nearly perfect. When I turned on Brilliant Color, blue shifted slightly toward green, and red shifted slightly away from green. In other words, the red/blue axis tilted a bit from where it was supposed to be. When I recalibrated it with Brilliant Color on, the gray scale looked even better, with no red bump at the low end. I watched real-world content with both calibrations and decided that I preferred the one with Brilliant Color on, so that’s what you see in the accompanying charts.

With Dynamic Black off, I measured a black level of 0.010 foot-lamberts, which isn’t very good, and a peak-white level of 16.9 ft-L, which is very near the digital-cinema standard. When I increased the Dynamic Black setting, the black level got lower, and the peak-white level got a bit higher. I ended up setting Dynamic Black to its highest level to achieve the measurements at the top of this section. (Normally, I dislike dynamic-contrast adjustments, but it didn’t bother me here, so I left it on for all my viewing.) When I enabled Adaptive Contrast, it brought the black level down even more and raised the peak-white level to 20.7 ft-L, but it also changed the colors in real-world material, so I left it off.—SW
