With the TheaterPro D6500K Mode selected, the HD-70FN97's grayscale measured very close to the 6,500-kelvin standard. Minor service-menu adjustments helped remove a slight blue bias at the low end of the scale, but the grayscale was mostly good to go out of the box. After adjustment, grayscale tracking was within ±200 K from 20 to 100 IRE - very good performance. I measured a -20% green color-decoder error on the set's HDMI input, but it was error-free via the component-video input. The set's red and blue color points were also very accurate. Green, on the other hand, looked oversaturated and slightly yellow.
Overscan - the amount of picture area cut off at the edges of the TV's screen - measured 4% for HDMI and 3% for the component-video inputs. Both 1080i and 720p multiburst test patterns were fully resolved via HDMI and component-video inputs. Picture uniformity was generally good, especially during off-axis viewing. A slight yellowish tint showed up on full-field gray test patterns and black-and-white movies, but I didn't notice it on color programs.
