Calibration settings for HDTV content

[zarusoba10]

Just last week I got a colorimeter and was able to make the display sRGB compliant. I’m satisfied.

So I decided to make a 3D lut for watching HDTV content (mainly Japanese animation). I heard that the gamma of HDTV is 2.4, but the information out there says that there is a problem with BT.1886.

I don’t understand the difficulty yet, but I would like to know the recommended settings for display cal to watch HDTV content.
Is “2.4 power gamma” sufficient for EOTF?

The display I’m using is a typical IPS display with a contrast ratio of 1000:1.

Then don’t use Rec1886, you won’t get 2.4. Usually try 2.4 relative black ouytput 100%.

Of yourse you can test by yourself, calibrate & validate and see resulting 2D plot “gamma value” (Y) vs RGB input (X). Rec1886 will bend (lower) gamma value near blacks by specification.

Also, these recommendations assume you’re viewing in a dim (5-nit) environment. If you’re viewing in a bright environment, target 2.2 instead

And if you watch movies in a complete dark room, use 2.6 gamma.

I’ve hypothesized about that as well, but some people argue that’s not true. I think you should go with whatever looks good to you. Ideally, the standard calls for dim. So you’d have a dark room with a bias light
