Calibrating NEC PA271Q for Rec.709 with SpectraViewII
« on: November 23, 2021, 01:39:52 am »

What target should I use to calibrate my NEC PA271Q for Rec.709? I need to set the monitor in the correct space for use with Premiere Pro for video editing. There's no prebuilt target (which is a bit strange tbh) for Rec. 709, so what should I use? Should I edit either the "sRGB Emulation" or "Broadcast Video" (does it matter which one?) targets with the following settings?

White Point = D65
Intensity = 100cd/m2
Contrast Ratio = Default
Gamma Curve Vlaue = 2.40 *or*. BT.1886?
Color Gamut = sRGB (as Rec. 709 has the same RGB primaries and colorspace as sRGB)?

Thanks!

Doesn't matter; edit either or from scratch, as long as you enter then save the target with the same and correct values required.

Thanks Andrew. That's what I thought. I'm just not 100% sure on the settings I listed above, but I think they are correct. The only interesting one is choosing BT.1886 vs pure power 2.4 gamma.

I'd check the specs here:
