The HP SLC3760N's Movie mode, coupled with its Low color temperature setting, came relatively close to providing the industry-standard 6,500-degree kelvin grayscale across the full range of brightness, though the white balance tended a bit toward red in the middle of the range. The Low-Mid color temp setting was off an equal amount toward blue, so I stuck with the Low setting and performed a service-menu calibration on the TV that brought it right into spec. Still, even without service-menu adjustments, either setting would probably be close enough to 6,500 K for all but the most critical users.

Color points for red, green, and blue were fairly accurate, though the color decoder exhibited a -22% error on green. Fortunately, this wasn't bothersome in HD program material via the HDMI digital input, through which green objects and landscapes came across as natural and appropriately saturated.

Via its HDMI input, the HP fully resolved a 720p multiburst test pattern from a Sencore signal generator, though the same pattern in 1080i showed some noise in the finest lines of the pattern and some unusual ghosting in a crosshatch portion of the pattern that wasn't detectable in program material. The patterns actually looked better through the component input: 720p was perfectly resolved, and 1080i signals appeared cleaner, with the ghosting eliminated.

Overscan, which describes the portion of the image cut off at the screen edge, was 2.5% - an average amount. Resistance to false contouring, as assessed using the Banding pattern on the Avia Pro test disc, was very good, with only narrow bands apparent in the gray portion of the pattern at a viewing distance of 7 feet; the effect essentially disappeared at a distance of 10 feet. Banding in the red, green, and blue portions of the pattern was virtually undetectable at 7 feet.
