Just purchased a TCL 43″ S517, It is Wide Gamut according to Rting.
I am not quite sure which correction to use w/ the i1dp.
Does anyone know ?
It meters 90% dci-p3, so according to florian, should be using the panasonic vvx correction?
I attempted to use the panasonic vvx correction, but then the mode switches to refresh instead of LCD
Is that suppose to happen ? is the panasonic vvx not for lcds ?

Yes.
Framerate != refreshrate.
I meant if i had my monitor at 23.976hz vs 60hz, will the colors meter differently . and between the lcd/ refresh modes.

Generally, no, but some displays with strobing/scanning backlight may loose brightness in strobing/scanning mode.
Hai, Florian, I’ve been using the 2.2 gawt w/ 100% black output offset 3DLUT, for Madvr HDR->SDR, based on your strict prescription on another forum.
I noticed that while it does maximize the effect of HDR highlight/contrast, it also cause a bit of black crush. This is more prominent if I leave the room light on, where it becomes even more difficult to see dark detail, ontop of eye burning highlights.
Is reducing black offset completely inappropriate for color accuracy ?
Is there some other way to lift the black/shadow detail a bit ?
Finally, what is your opinion on HDR in regards to viewing comfort/ pragmatism, because while I agree it is a new dimension for video-artists, more than half-the-time, it hurts my eye, and I have to squint.

That “prescription” was only for direct madVR shader tonemapping to 3D LUT tonemapping comparisons (due to madVR shader tone mapping not having the ability to take display black level into account).

No, and you can set it to any value you like. 0% black output offset is equivalent to “pure” BT.2390 (which incorporates black level lift).

This depends on the viewing environment, display setup and how the HDR material was mastered. If HDR is used overly liberally, it will not be very suited for dimmer viewing environments. Ways around this are, as usual, to reduce the peak luminance of the display, increase the target peak luminance for the 3D LUT (or in madVR settings for the shader) – which has the effect of making HDR overall dimmer, adjust the viewing environment, or any combination thereof.

So for Madvr Pixel-Shader HDR to SDR, it must be the 0% offset ?
and using the 3D Lut tonemapping , it can be any % offset ?

Only if you want to compare the two and minimize differences.
If this tv is ~93% P3, and I’m using the HDR-SDR Shader, Should I select rec2020 as the source color space for the LUT, or select Dci-P3 as source color space.
The reason I ask is, The Madvr readout sometimes says rec2020, and sometimes it says rec2020–> Dci-P3
But if I put a rec2020 source lut into the slot, it always picks the rec2020 lut, never from the dci-p3 slot.
A bit uncertain as to how madvr is interacting and choosing the LUT.
Using rec2020 as source colorspace option, seems to look less saturated than selecting dci-p3 as source colorspace.

For HDR, the source for the 3D LUT needs to be Rec. 2020. For SDR, the source for the 3D LUT needs to be Rec. 709.
The reason I ask is, The Madvr readout sometimes says rec2020, and sometimes it says rec2020–> Dci-P3
This depends on the HDR metadata. The container format for HDR always uses Rec. 2020, but the effective encoded gamut is DCI-P3.

From HDR Material –> Madvr’s HDR to SDR Pixel Shader –> DCI-P3 Gamut TV,
The 3D lut should be rec2020 source , and placed in the rec2020 box ?
