    See the attached report. I calibrated my Dell UP2716D monitor (Custom Color mode with RGB Gain at 100%), connected to Decklink 4k card through HDMI. Calibrated to 100 cd/m2 by lowering brightness. Contrast control left at 75% default. Contrast result is 629.1. Did I do something wrong, or is this about the best I can get with this monitor at 100 cd/m2?

    Do you adjust whitepoint via the 3D LUT? This naturally reduces contrast somewhat.

    Yes that is what I did. I didn’t know adjusting whitepoint via LUT would reduce contrast. I did it that way, so I could keep “uniformity compensation” turned on. But I guess I’ll have to turn that feature off, and adjust RGB Gain manually and try to see if I get increased contrast.

    Probably not, but…

    ..this is likely going to help (although with the less uniformity drawback).
