Optoma HD72

Color temperature (before/after calibration)
Low window (30 IRE): 7,243/6,660 K
High window (80 IRE): 7,150/6,374 K
Brightness (100-IRE window before/after calibration): 7.6/12.1

Before calibration the Optoma HD72's grayscale varied by an average of 716K from the standard, which was fifth-best of the group. Afterward it varied by a sixth-best 176K. Its real-world contrast ratio of 132:1 was best in the group. The accuracy of red, green, and blue was about average for the group, with green again the worst, and color decoding was very good. Resolution with 720p sources was perfect via both component-video and HDMI, and other resolutions were very good. Pixel structure was slightly more visible than on other DLP models but still invisible from normal distances. Edge enhancement was negligible on all inputs. Uniformity was very good, and black levels did not fluctuate depending on program content. Overscan measured 1% along the top of the screen and 0% elsewhere. Focus was very good; some fringing was visible from 7 feet but not from further away. Standard-def video processing was excellent on most HQV patterns, although some jagged edges were visible in the most-difficult sections.
