How can I get the best HDR image out of my Samsung QLED?

I've decided I'm going to give HDR a proper try, as after learning that there doesn't seem to be any clear standard to calibrate to like with SDR, I Ignored it. I'm all about trying to get the image to how it's "supposed" to look.

Anyways I'm hope some people who know more on this can point me in the right direction for my Samsung Q60R.

- I understand I should leave backlight and contrast at max, but what about black level (brightness)

- Contrast Enhancer, some say off, some say low and even some say high

- Colour space, I have Auto, Native and when selecting Custom, I have the option of DCI P3 and BT 2020, both really drastic in colour differences. I have heard people suggest auto and some suggest native.

Just hoping I can get this info right as if not and it's just so varied I'd probably stick to SDR.

If calibrating for best accuracy, Movie, Warm2, Backlight max, Brightness 0, Contrast Enhancer off, Color Space Custom DCI-P3. Start with Contrast max, but measure the EOTF curve and you will likely find it elevated, in which case incrementally reduce Contrast and re-measure to find the setting that gives you best fit to the reference EOTF curve.

Thanks Thoth, but unfortunately I don't use any measuring equipment, however, when I view a pattern in HDR with shades of white, I definitely notice it takes on a pinkish hue, now if SDR is anything to go by you just reduce contrast till it's back grey again, should I do the same here?

Also why DCI P3? Isn't BT 2020 the standard, will that also be the correct option for HDR games too?
If you aren't using any equipment, then you're probably better off leaving Color Space on Auto and leaving Contrast at max, plus the other settings I listed. As for why DCI-P3, it's because Samsung makes incomprehensible decisions sometimes. The DCI-P3 setting does the sensible thing; the BT.2020 setting appears to remap/compress the entire BT.2020 gamut down into the DCI-P3 gamut (a mapping not defined in any standard), which makes all colors inaccurate. The Color Space setting is the same for HDR games. As for the pinkish hue, I'd rather not speculate without measurements. For HDR you want to be evaluating with 10% window patterns, not full screen patterns.

I did as you said before as well and wondered why the DCI colour space was so...pinky red lol. Auto does seem much better.

HDR is a whole new ball game and a lot of new stuff to learn.
