TEST BENCH
With the Mitsubishi Unisen LT- 46153's Natural picture mode and Low color temperature presets selected, grayscale tracking measured ±209° K of the 6,500-K standard from 20 to 100 IRE. Adjustments made to the high/low red, green, and blue controls in the Advanced Picture menu reduced that spread to 144 K from 20 to 100 IRE, but the benefit here was so slight that I'm sure most people could live happily with the picture in Natural mode.
The set's color decoder displayed red and green pull in excess of 10% in both the Natural and Advanced Picture modes. Outside of a slight level of green oversaturation, both its primary and secondary color points measured close to the SMPTE HD color specification. In both cases, adjustments made in the Advanced menu's PerfectColor menu helped to correct any color errors.
With the Mits Unisen set's 2.2 target gamma selected, gamma measured closer to 3.0. Overscan - the amount of picture area hidden behind the edges of the TV's screen - measured 0% for 1080i- and 1080p-format high-definition signals with the Full Native screen format selected, and 6% for 1080p Standard. The TV displayed 1080i- and 720p-format test patterns at full resolution, and a 480i (DVD) resolution pattern also revealed full detail via the componentvideo input. - A.G
