Digital Projection M-Vision Cine 230 DLP Projector Measurements
Peak white level: 18.2fL
Black level: 0.008fL
Peak contrast ratio: 2275:1
Peak-white and black-level measurements were taken in Economy lamp mode, which provided plenty of light for an image of 75x42 inches. Adaptive Contrast was disabled; turning it on yielded higher a peak-white level but no decrease in black level, so the peak contrast ratio would be higher—in fact, it was close to the factory spec of 3000:1—but I preferred to watch real-world content with Adaptive Contrast turned off.
Grayscale & Color Temperature
Pre-calibration, with Color Temperature set to 6500K, the white points were tightly clustered, but tending slightly toward red.
After calibration, the white points were right on the money.
Even though Color Temperature was set to 6500K, it measured between 6100K and 6200K across the brightness range.
Post-cal, the color temperature was very close to 6500K across the brightness range.
The pre-cal color tracking shows an excess of red and a slight deficiency of blue at the higher light levels.
After calibration, the color tracking was spot on.
Setting the Gama control to Film resulted in a measured gamma of 2.21, which I much prefer over the reference value of 2.5. At 2.21, shadow detail is more visible.
The green-blue axis was ever-so-slightly undersaturated, but not that anyone would notice on real-world content. Otherwise, you can't get much closer to Rec.709 than this.
