V-Ray on HDR10 Monitors?

[martinkamminga97]

Hey everyone,

Since HDR10 monitors are on their way, I was wondering what that could mean for 3d rendering.
I'd like to understand how/if it will affect V-Ray and workflows in general, since most people will still view your work on 'SDR' monitors.
Also, will this somehow shed a different light on the colour mapping discussions (aces, filmic) that have been on the forums lately?

I was just wondering since I couldn't find any information about this,
and all the information out there is targeted to consumers : - )

I'm not quite sure myself what it means yet. We will need to take into account the response curve of the monitors and adjust the displayed images accordingly. It is likely that the traditional sRGB display color curve will need to be replaced with something else that preserves the high dynamic range. In the ideal case, we would be able to just display linear colors and remove the requirements for any sort of HDR compression in the VFB, be it hilight burn or filmic tone mapping or something else.

I'm guessing that it will take a while for things to settle in a common workflow. There are also several different HDR display technologies and it is difficult to predict which one will win out.

Best regards,
Vlado

Can someone explain the benefits of HDR monitors? If I understand correctly, they display wider range of colors, meaning colors won't have to be converted to sRGB in order to be shown correctly? To my knowledge, all mid and high range SDR monitors are already able to reproduce every color correctly if the HDR color data is processed correctly so the difference is the (complete ?) removal of the color processing step? Is this the only difference? Also, what happens with the rest of the situations where you aren't viewing HDR content? Won't these look weird on HDR monitor?

Thanks for the reply Vlado.

I believe HDR10 uses the Rec. 2020 gamut, which supports 8 bit and true 10 bit.
The thing with HDR displays is that they come with a standard brightness (nits) and can increase their brightness to a peak value. This is what makes HDR content so beautiful (according to the internet).

I don't know about the colour processing. It's a 10 bit panel, and colours have to be converted into something?

But, since Rec. 2020 is indeed larger than sRGB, I believe 8 bit content will just look normal on an HDR display, and have a fixed brightness?
