Color temperature (before/after calibration):
20 IRE: 7,110 / 6,186 K
30 IRE: 6,958 / 6,536 K
40 IRE: 6,989 / 6,647 K
50 IRE: 6,875 / 6,551 K
60 IRE: 6,897 / 6,550 K
70 IRE: 6,793 / 6,553 K
80 IRE: 6,699 / 6,527 K
90 IRE: 6,616 / 6,516 K
100 IRE: 6,748 / 6,507 K
Brightness (100-IRE window): 30.3 / 29.1 ftL
With the Night picture and Standard color-temperature presets selected, the Hitachi displayed a slight blue bias, tracking +250 to +400 K off the 6,500-K standard. Adjusting the grayscale in the user menu brought that to within +150 K from 30 to 100 IRE - an excellent result. The set's green and blue primary color points were slightly undersaturated, compared with the SMPTE HD color spec. Also, color-decoder tests revealed a moderate red pull.
Two unstretched and non-zoom 16:9 aspect ratios were available: Standard 1 with 5% overscan, and Standard 2 with 0% overscan. Resolution via both HDMI and component video was excellent with 720p and 1080i/p signals, in general giving slightly better results for the HDMI over component video and for 1080i over 1080p. The video processor did have some problems with our standard-def motion torture tests, although none were noted with regular program material. Screen uniformity was excellent, and the picture remained bright and clear at up to 45º off-axis. Black-level performance was a bit disappointing, with a fair amount of residual light remaining at 0 IRE.
