Of the Sony's various picture presets, Cinema delivered the most accurate color reproduction when Low color temperature was also selected. Grayscale tracking was ±1,026 degrees kelvin of the 6,500-K standard from 20 to 100 IRE - a poor performance level. Adjustments made to the red, green, and blue gain and bias controls in the Custom color-temperature submenu improved grayscale tracking to ±147 degrees K from 30 to 100 IRE, although the dark 20-IRE window still showed a significant reddish bias post-calibration. Color-decoder tests revealed zero red and green error on the HDMI input, and a minimal +2.5% green on component video. Compared with the SMPTE HD specification for digital TV colors, the set's red, green, and blue primary color points showed only slight oversaturation. However, its green point displayed a yellow-greenish orientation, and the yellow secondary point was fairly oversaturated as well.
The Sony's 16.3-ftL post-calibration brightness was about average for a projector in its price range. In my room, its native contrast ratio (Iris modes turned off) measured as 1,970:1 - an excellent showing. Meanwhile, at 10,350:1 the Auto 1 Iris mode delivered the best-case contrast ratio. A degree of light spray emanating from the projector was visible at the top and bottom of a 16:9 screen. For this reason, it will be a good idea to position any screen used with the VW60 against a completely black background.
Overscan - the amount of picture area cut off at a display's edges - measured 0% for 1080i/p-format high-definition signals with the Overscan mode turned off, and 4% when it was switched on. The Sony displayed 1080i/p and 720p test patterns with full resolution on both the HDMI and component-video connections, although noise was visible on the latter input. Picture uniformity was excellent: Black-and-white fields showed perfectly even brightness, while gray-field patterns were free of color tinting - a definite issue with the two previous Sony projectors I've tested.
The Sony passed all the torture tests on the Silicon Optix HQV high-def test disc. And its upconversion of DVDs and standard-definition TV programs also proved to be clean and artifact-free. The projector's video noise reduction processing worked well, smoothing out background noise without significantly reducing picture detail with both standard- and high-def programs.
