Test Bench
Full-On/Full-Off Contrast Ratio: Infinite
All the following measurements were made in Expert Picture Mode. With the Contrast and OLED Light controls set to produce a peak white level of 29.7 ft-L and the Brightness control set to 51, the black level was immeasurably low, resulting in an effectively infinite contrast ratio. But the Brightness (black level) setting is critical to this result. When I raised the control by one step, to 52, the black level rose to a quite visible 0.0074 ft-L, dropping the full-on/full-off contrast ratio to 4,014:1. To minimize the occasional appearance of the set’s poor dark-gray non-uniformity mentioned in the review, I performed much of the reviewing and the remaining measurements with a Brightness setting of 50.
