Set your tv its widest gamut SDR mode. Use that with madvr's dynamic tonemapping. HDR only specifies the data spec, the actual Dynamic range in both HDR / SDR on the SAME tv is more/less the same.

A bit confused.I have a BT.709 display and I am like this.
Is it suggested to create a gamma 2.2 BT.2020 3dlut(removing hdr to sdr 3dlut obviously) and put it in the calibration tab leaving madvr to do the tone mapping or am I doing the same thing? Last edited by Damien147; 19th April 2019 at 18:13. |

Here's a very interesting conversation about 3DLUTs in madVR.

this is being so finicky. I got it to 59%, I tinkered around checking different movies, that's all, just checking different movies, then I stop it for a second and when I go to check it again it's back up to 90%. I didn't even do anything with it.
Edit: I checked task manager and it's bringing up like 4 instances of madvrcontrolpanel. I click all but one and it goes back down in gpu usage. Last edited by toki; 19th April 2019 at 20:07. |

NO, Put tv in its Widest gamut mode, @ whatever brightness you like, or the highest. Then, run dispcal 3d lut for SDR, Source DCI-P3, 2.2gamma, relative, 98% black output offset. absolute colorimetric w/ white point scaling Leave black point correction alone unless using plasma/oled/CRT. Put that into the dci-p3 slot in madvr calibrations, under the SDR section. In HDR section, set to use pixel shader for dynamic, And it will just use that lut after tonemapping.. It is recommended you watch hdr tonemapped movies in near pitch black conditions, room around 5-10cd. Because the relative lut makes it very dark. If you use rec 1886 lut which is absolute tone, it will brighten black detail for a bright room, However it won't look very HDR-y because the contrast seems gone. I also don't recommend using 100% black output offset, because it's just a little too much crush. I've compared dark images extensively against my CRT, 98% brings out just the right amount of detail, without eating into the contrast.

Also, "madvrcontrolpanel"? Do you mean "mad* home cinema control"? I only ever see one of those, what is bringing them up?

The whole point is to have calibrated sdr,hdr + what's needed for hdr to be displayed on bt.709 display.To conclude shall I stay with how I am or gamma 2.2 bt.2020 in calibration tab is better for me?

madVR tonemapping is nearly for sure better but cost a lot of performance. if you are using madVR tone mapping things get more complicated. @tp4tissue can you stop things like this please... |

Still I think there's a reasonable doubt about possible clipping when the source profile of the 3DLUT is BT.2020. This is from madshi 11-24-2017:

I guess it maps them back in gamut anyway, but maybe using a source DCI-P3 3DLUT is safer. |
