Sony BRAVIA VPL-HW15 SXRD Projector HT Labs Measures
Full-On/Full-Off Contrast Ratio: 8,942:1
Except as noted, all of the measurements here were taken with the projector in User mode, adjusted for the most accurate image, with the lamp power on Low, the Gamma Correction on Gamma 4, and the Advanced Iris set to Auto 1.
The Sony’s full-on/full-off contrast ratio is excellent, and its black level equally impressive—and not just for a modestly priced projector. With the lamp on High, the projector’s contrast was 9,350:1, with a peak white level of 28.3 foot-lamberts and a black level of 0.003 ft-L. With the Advanced Iris off, and the lamp on Low, the full-on/full-off contrast ratio was 2,511:1 at a black level of 0.008 ft-L. The Sony is ready for any reasonably sized screen.
The Color Tracking charts below show how well a display adheres to the D65 standard white point; the tighter the overlap of the three primary colors, the nearer the result is to D65. The Before Calibration result is for the Low Color Temperature setting. The After Calibration result is exceptional, apart from a small dip in the blue level in the mid-brightness region. The Delta-E (a numeric measurement of how closely a display comes to the desired D6500 color temperature, with values under 4 considered good) was under 1.7 from the darkest point at which our color instruments are reasonably accurate (20 IRE) to peak white (100 IRE).
The CIE chart above shows the Sony’s color gamut in the Normal Color Space setting. It’s very good, if just slightly undersaturated in the red-green axis. As noted in the review, attempts to tweak this in Sony’s RCP feature could move the points outward, but not without small but undesirable side effects.—TJN
