HDR looks like shit , when I use that option , it's really dark and has very few 'sparkle highlights' I know it is intended for projectors , but I am getting amazing results now and I have many many options to tweak it It was only until recently , that I was really happy with result on my new Philips in regards to HDR. Two Things did that: 1- using the BT709 (old) 3DLUT , shared by Madshi 2- Tonemapping (using Measurement files v 86) (My favo option and my current one, I'm using NEO-XP's latest config settings, he's on the AVSforum) Using the live algo for HDR measurements should be providing way better results than the (static) HDR10. I think this is comparable , but even better than using HDR Meta Data like HDR10+ or DV (current results with this normal brightness, incredibly sharp , beautiful colors and amazing HDR) I don't understand why I could not use a calibration 3DLUT , I intend to make a 709 & a bt2020 (DCI-P3) one, using DisplayCAL I think your last 'dashed' remark is incorrect. U CAN use bt709 as an external 3DLUT , WHEN your are tonemaping to SDR, this will show HDR on ur TV , ur TV just won't tell you that is it is an HDR signal Please elaborate ;-) I purchased an X-rite i1Display Pro for 230 euro's just for that....

- it adds the possibility to do "static" hdr2sdr conversion which is waaay faster than the dynamic tonemapping implementation of the test versions. Quote:
- which option? hdr passthrough? Then something is not right with your setup, it should be clearly way better with it than with madvr's dynamic tonemapping. Doesn't the Philips TV have dynamic tonemapping implementation as the newer LGs do? Quote:
- you are/can be right if you use madvr dynamic tonemapping with your TV in SDR mode -- do you? if so, in which nits setting? - or you could use it as @SamuriHL does / did - or you could "just" passthrough to the display and let it does its job (that's what I use, and here) You can't with passtrhough. You can with madvr's dynamic tonempaiing + your TV in SDR. Quote:

- what nits settings do you get on your TV with your current settings? (I assume it's not HDR mode) 120 / 140 / 150 nits? - if you try to go higher in your TV setting in SDR mode, you will get ABL that will ruin everything (there are at least 3 (!) different ABL algo on recent LG Oleds) - you can't compete a ~700 nits HDR video with a 150 nits tonemapped SDR signal That's why that beta thread on avsforum has the "projectors" in its title

You can also do plain HDR 3D LUTs with HDR output with DisplayCal with a BT.2390 tone curve.

What's that "BT709 (old) 3DLUT, shared by Madshi"? Quote:
BTW, I didn't know that OLEDs had such a low peak 100% window. |

Neo_XP doesn't have a HDR capable OLED TV but an earlier model, just telling ...

I thought that the 1st gen OLED's started with UHD support. My LG is from late 2016 , also has HDR , but a max of 420 nits...

There is an option in the test build to use a HDR2HDR 3DLUT now (with settings for the output gamut and HDR nits) but I don't know how if it gives good results in practice.

202 target peak nits translates to 202 nits of SDR brightness. If your display is actually calibrated to 202 nits in SDR mode, you are largely getting 1:1 representation of 0-100 nits for most scenes up to 1,000 nits frame peak brightness and the remaining 102 nits (202 nits - 100 nits) is allocated to rolling off the specular highlights in each scene. If your display is calibrated to less than 202 nits in SDR mode, then you are rolling off some of the image towards black at the ratio of 202 nits to your actual calibrated SDR brightness (e.g., 202 target nits / 150 SDR nits = 1.35x darker representation of the source values). If your display is calibrated above 202 nits, then 202 target peak nits in madVR would brighten the mastered PQ source values by some amount.

Thanks guys. I'll do some more testing in fullscreen exclusive mode. Cheers, Allan .......................................................... edit: Tried fullscreen exclusive mode but had to disable it as video would flash black a then maroon.

Hello everyone!
Guys need your support because I'm going crazy here. My setup was: - Sony LED XD93 (4K, HDR) - AVR (4K, HDR) - Nvidia 1070 - Madvr updated to last version - MCP BE - HDR option off in Windows Everything was running good (24p, 4k, HDR movies) with RGB Full and 12 bit sett in nvidia settings and player, 10 bit or more in madvr setting and 3dlut file in madvr for the calibration (calibrated to DCI P3). Nothing else relevant that I feel to point out. Yesterday I changed the TV with a new OLED GZ950 by Panasonic and when I tested MPC I noticed some problem: with HDR I noticed a lot of blocking and the whites were more pink than white. Obviously I deactivated the 3dlut proflies and switched to "this display is already calibrated" setting 2020 and 2.2 gamma. I use madvr only for 4K HDR Movies and my TV switch to HDR and BT2020 with 2.2 gamma. I checked online and I figured out that I was using the internal codes (which were fine before...) and someone suggested to reinstall and use LAV Filters. I did it and it made the situation much much better but I still can see some blocking and banding and the whites still have some noticeable pink. I have to clarify that this problem apparently it's present only with the HTPC and Madvr since Netflix, the PS4 and other apps/devices do not have these issues at all (with or without HDR). I tried everything: reinstalling the nvidia drivers, changing the bit depths in Madvr, changing the gamut in the TV Settings (DCI-P3 looks a bit better/less pink but I lose a lot in general color...) but nothing solved the problems: some blocks, noticeable banding and the pink. Last note: if I turn on windows HDR and watch an HDR movie with VLC everything is fine but I do not want to lose madvr quality. |

I am using HDMI 2 which is the arc one. My cable was good enough before so I can't see why wouldn't be good now. My other TV was a Sony 4K HDR 2016mid/High range...
Any PC or madvr setting I need to check? After further test I can confirm that mainly the problem is the pink tint (you can't see it on the whole mage but if you check you can see it on clouds r similar) and banding. The blocks issue is quite minor even if actually there but mainly you see it in certain scenes. P.S. the source files are very very high quality 4K HDR |

Is SLI expected to help madvr? I have 2x2080 Ti in SLI/NVLink and I noticed that the 2nd GPU is under 20% load with madvr (dxva2 copyback). I was under the impression that SLI doesnt add much to madvr but seeing this I am wondering if I can get both GPUs to share the load more effectively? I have maxed out my usual settings in NGU etc and the rendering times are still about 20ms with 1st gpu at 50% load and 2nd at about 20%. Running at 4k 120hz.

To what I've read , MadVR doesn't support it

With a Panasonic GZ950, you should get a better picture by sending the HDR source to the display with passthrough. Panasonic follows the SDR range 1:1 with the PQ curve and does its gamut mapping with correct colorimetry. It can also do dynamic tone mapping of the specular highlights in each scene. That, or compress the HDR source with pixel shaders in madVR and send it as HDR to the display.
