FULL-ON/FULL-OFF CONTRAST RATIO: 1,700:1

Calibration measurements were taken in the HU85LA's Expert Bright mode. Display enhancements including dynamic contrast were disabled for calibration and I selected the Warm color temperature preset, 2.2 gamma, Auto color gamut, and took advantage of the full 22-point grayscale calibration option. Calibration work was done using a Colorimetry Research CR-100 colorimeter profiled to a Colorimetry Research CR-250 spectroradiometer via Portrait Display's CalMAN 2019 (www. portrait.com). Measurements and viewing were carried out using a 100-inch diagonal 16:9 aspect ratio Screen Innovations Zero Edge Pro screen with Short

Throw material (0.6 gain). Full-on/full-off contrast was measured after calibration was complete with my Colorimetry Research CR-100 approximately 1 meter from the screen. The projector's 1,700:1 measurement is nearly double the native contrast I've seen with other XPR DLP-based projectors I've tested. Engaging the LG's dynamic contrast feature didn't yield any difference in peak contrast performance at any setting.

SDR calibration was measured with REC.709 and a gamma of 2.2 for targets. The grayscale leaned heavily toward blue throughout the entire sweep, a result that wasn't completely unexpected given the projector's heavy reliance on blue lasers. The projector's 22-point calibra- tion tools delivered excellent results for grayscale and gamma. Colorimetry was a bit more limited given the onboard tools, though peak post-calibration results still measured under the perceptible limits.—KRD
