Does Madvr's dithering work better in 60hz than say 24hz ? How does it work ?

madVR does not use temporal dithering so it does not matter what the refresh rate is. That said the dither pattern changes slower if using "change dither for every frame." This is the only aspect of dithering that is impacted by the refresh rate.

I usually have both that and "use colored noise" disabled anyway.

Do you still use the TV's own dynamic tonemapping this way? I assume not.

Have you managed to compare the TV's own dynamic tonemapping vs the way you use it now? (I haven't yet, or maybe I did )
I'm asking this, because I compared the live ago in SDR mode (OLED light was at the max 100) and the produced image was softer than with hdr passthrough, the latter was way sharper.
(I use the TV in PC mode for getting chroma 4:4:4)

The softer image would come from poorer EOTF tracking. Were you still doing a gamma conversion with a 2.40 3D LUT? That could make things softer.

The HDR output option should only shave the brightest highlights from every source and eliminate most tone mapping by the display because the source will arrive pre-compressed. That should be very similar to way the TV already works. The BT.2390 roll-off doesn't compress 0-100 nits (the knee point starts higher) when you set the output to 700 nits.

Some have claimed that the C8 and C9 are boosting the brightness of the image at times with dynamic tone mapping. I don't know if that is true or not. If you compressed the source and sent it to the display with dynamic tone mapping enabled, it could also influence the result, but I don't know by how much.

Does the calibration report go up to 700nit ? maybe the tv snipped the bright patch, so the 3dlut is inaccurate.

I don't use them myself. I have my own settings that won't help anyone that I use. His latest build and settings were getting very good results afaik.

It does increase the brightness at times. I don't particularly mind even if it's technically not correct. I keep dynamic tone mapping on because in theory it should do LESS tone mapping given that madvr has already done the tone mapping before sending it. I'm quite impressed with the quality of the output.

thought i'd see what all the fuss was about with HDR tone mapping, but just decided to try the current .17 for now, however before I try anything I check everything is working properly, 3D doesnt work with this version properly, it plays but plays only in top left hand corner all squashed up. If I drop back to v0.92.14 its fine so defo an issue with this version. (v0.92.17).

I havent been reading for a while so i'm a bit behind, whats with this new beta version, seems to be loads missing from it or is MADVR now an installer package?

I managed to document most of the features in the current betas over the past year in the link in my signature. If you start at the HDR section in the guide, there is plenty of information there.

I don't think 3D playback has been touched, so I don't why you would be having issues. All the work went into HDR playback.

You can install that build by simply overwriting the existing installation files with the few files provided.

so you just copy those few files over the top of the current .17 version, isnt there a full beta version with all the files?

No, these are just test builds, not really beta versions.

Hello, I could use some help regarding HDR and 10bit.

1. When I try to play HDR, only Madvr OSD is in HDR (and 10bit). https://i.imgur.com/T6p8cBG.jpg

2. When playing HDR movie I cant enter fullscreen exclusive.

Settings: https://imgur.com/a/zc1xLAB

Hey guys, which movie "teases out" the new dci-p3 gamut ?

I'm not seeing a huge difference between wide and standard gamut tv in movies, side by side, both ran through displaycal and i1d3.

A GTX 1060 would do the job.

You're lucky.

Every time I say the same on this very topic, I get death threats from die hard madvr users yelling that madvr can't to anything with only a GTX 1060 and that anyone serious about picture quality should mortgage their house and buy a RTX 2080 TI...

As 1060 3Gb user I would recommend 6Gb version.
