IN THE LAB
Precalibration measurements were made after initial adjustments with the Avia test DVD. The set provides three color-temperature options: Cool, Neutral, and Warm. Prior to calibration, the Warm preset measured close to the NTSC 6,500-K standard on the high (100-IRE) window but displayed a strong bias toward green on the low (20-IRE) window. For this reason, I recommend hiring a professional to calibrate the set's grayscale. The Imaging Science Foundation (561-997-9073) can help you locate a certified technician.
After calibration, grayscale tracking was only fair, ranging ±500 K at each 10-IRE step between 20 and 100 IRE. The performance of the set's 3-D digital comb filter was excellent, delivering clean transitions in an SMPTE color-bars pattern when the composite-video inputs were used. NTSC decoding was accurate. Geometry was excellent in both the set's widescreen and 4:3 display modes. - A.G.
