Best settings for HDR?

[three daug]

In regards to HDR what settings are people using, I haven't dabbled much but I prefer rec2020 and I've set to brightness to about 50. Just curious as we are in the wild west days of HDR settings. I've got an lg27uk650 monitor with a vega 56(with 64 bios) driving it.

I have the same monitor. I use brightness 100 and DCI-P3.

First Rec2020 is a wider color gamut than DCI-P3: https://image.benq.com/is/image/benqco/color-gamut-8?$ResponsivePreset$&fmt=png-alpha

Use choose Rec2020 unless you have a reason, like you're using a projector that only supports DCI-P3.

When you think HDR, there are actually 2 things going on:
1. Potential color combinations (8-bit vs 10-bit).
2. How far apart possible colors are from each other (color gamut like Rec2020).

These are independent of each other but are often shown together. You can have 8-bit color with Rec2020, but because the gamut takes up so much more of the spectrum, you're more likely to have inaccurate colors and a lot of banding. 10-bit color masks these issues because it offers billions, rather than millions of possible colors in the same gamut.

Rec709 is the older SDR standard. So with 8-bit color or 10-bit color, it's harder to differentiate because the differences between the colors aren't that far. Noticeable in some gradients, but not much else.

DCI-P3 was designed for movie projectors. It's essentially an in-between. Rec2020 is most-likely what the game was made for and what you should be choosing.

I might be wrong though. My monitor is 93% of DCI-P3, but only 70% of Rec2020. It's the outer-most colors where it has more trouble displaying.

When trying both modes in the game, DCI-P3 appears oversaturated, but this might be because I'm actually seeing the colors whereas I can't see those in the Rec2020 space with this display. The Rec2020 mode looks more muted, but I'm assuming that's how the game is supposed to look; not sure.

In terms of the HDR Intensity setting, it most-likely changes between the number of nits your monitor supports.

Since the game is graded at 1000 nits, I'm assuming a setting of 100 would be 1000 nits. That's way brighter than almost every PC gaming monitor today except a very select few (like 1-2 models). We'll have QD-OLED gaming monitors soon, and those might be able to reach 1000+ nits.

I'm not sure about the lower values. If 10 was equal to 100 nits, then that's not HDR. The lowest spec'd HDR is 400; therefore, 10 should be 400. If not, who knows. Honestly, this "intensity" rating doesn't make much sense to me, but you really want to set it to something so you avoid clipping.

If I plot those points on a graph, it's:

(3x/20) - 50

Replace `x` with your monitor nits.

For 600 nits (common), use 40.
For 700 nits, that's 55. Since we can only choose 50 or 60, choose 50.

It's also possible it really is a *10 scale; therefore, 60 would be 600 nits and 70 would be 700 nits. Not sure.

I used DCI-P3 with 100% brightness on my Samsung QN90A.

It just looks better than Rec2020. More colorful and punchy.

[Sawtaytoes]

Mine also looked more colorful at DCI-P3, but I figured that might be oversaturation.

I tried both and settled on DCI-P3 just like you because neither my monitor nor my OLED reproduce enough of Rec2020 (70-76%) versus DCI-P3 (90%+).

The colors of 2D items are wrong in DCI-P3 (like Senua's face in the menu), but 3D stuff is fine.

This game got hdr on PC? why does the store page not even have hdr mentioned I mean you can now look at a games store page and if it has hdr it shows it as well as if it supports controllers

[Sawtaytoes]

Steam doesn't have an HDR denotation on store pages. It'd be nice to have one, but that's not how they do it.
