FULL- ON/FULL- OFF CONTRAST RATIO: 1,046: 1

-

The measuremen­ts here were made using CALMAN measuremen­t software from Portrait Displays (www. portrait.com), together with a Photo Research PR-650 color meter, Minolta LS-100 luminance meter, and a Murideo/avpro (Fresco Six-g) test pattern generator.

Pre-calibratio­n measuremen­ts were made with the Benq V7050i’s Filmmaker picture mode active in the default settings. Postcalibr­ation measuremen­ts were made in the User mode. All measuremen­ts were made with the projector paired with a 1.1 gain, 92-inch diagonal Stewart CIMA projection screen.

The projector’s maximum full-on/full-off SDR contrast ratio was measured in Bright Cinema mode with Normal Light Output active. Using this combinatio­n, black measured 0.047 ft-l and peak white 49.2 ft-l for a contrast ratio of 1,046:1. Full-on/full-off HDR contrast was only slightly higher at 1,098:1.

Before calibratio­n, the Benq’s grayscale showed a pronounced blue deficit with the Filmmaker mode’s default settings active. Selecting

Cool Color Temperatur­e option instead of the default Normal improved grayscale tracking considerab­ly, while a calibratio­n using the RGB Gain/offset adjustment­s in the White Balance menu yielded a maximum 3.1 Delta E at the 50 percent brightness level. (Delta E is a figure of merit indicating how close the color comes to the standards, either D65 for the white point or the color coordinate­s for each of the primary and secondary colors that define the color gamut under test. Values below 3 are generally unnoticeab­le.)

With the Filmmaker mode’s default settings active, the Delta E of the V7050i’s color points averaged out to 6.4, with a maximum error of

15.3 for cyan. After making adjustment­s in the projector’s color management system menu, that number was reduced to 3.3. Coverage of the Rec. 709 color gamut topped out at 90.5% (with Color Enhancer adjustment at maximum), DCI-P3 at 94% (with Wide Color Gamut On), and BT. 2020 at 67.2%.

Post-calibratio­n, gamma mostly tracked a 2.4 target, with a maximum Delta E of 3 at 50% white. In HDR10 mode with Normal Light Output selected, peak brightness was measured at 216.6 nits on a 10% white window, with measuremen­ts at other window sizes ranging from 1% to 75% remaining within a +/10% range.

Picture uniformity was excellent: white full-field test patterns showed minimal brightness drops between the center and edges of the screen, and no color shifts. Our suite of video processing tests revealed below-average performanc­e, with the Benq tripping up on HD 2:2 pulldown patterns, along with several 2:3 pulldown cadences and mixed film/video tests.

Best case measured input lag with a 1080p source was 78ms in Filmmaker mode, making the Benq a below-average option for high-def gaming.— AG
