My 1080p bluray player (couple years old) has options for 4:2:2 ycbcr, 4:4:4 ycbcr, or RGB. With the UHD players I believe they offer those choices too, along with up to 12bit output. By default on 'auto' pretty sure they all output ycbcr at either 4:2:2 or 4:4:4

About due for an update here.

I spent way too much time testing all this curve stuff.
I've updated my settings for 130: https://postimg.cc/RJzNZd33
Pretty much just disabled FALL detail, it was too sensitive. FALL mod at 80% seems to be decent for extra brightness without losing much.

Curve is r13 now, probably my preferred for now. Hopefully the others like it too.
Not too sure how much the new normalization affects brightness, I haven't compared previous versions.

I'd reenable contrast recovery but I might wait, because I don't really seem to need it (personally, at least) with FALL mod.

This should be an option, again, you can't watch content normally to actually see what the curves do, unless you revert back to b128 (but there's the mdl clipping ). That's why I asked him to clarify that.

So, for all of these that happened in the latest builds, I went back to b113, until everything settles down

Different question: did any of you calibrated DoVi? If so, do you still have the DoVi config file that can be shared?

@SamuriHL, have you? I think you have all the tools for this, haven't you? It would be really nice from you if you can give it a chance ... and we finally mange to get rid of the elevated black crap

Hell no. These LG panels, especially the 18 series, are way too finicky to calibrate DoVi. As soon as you mess with the config it screws everything up in my experience. I've left HDR and DoVi alone other than SM white point @d65.

Thanks for posting your curve/settings. I'm dipping my toe into the new builds and yours is the first time I've actually liked what MadVR has done on my C6 OLED. I just amended the peak brightness to 650 nits of my panel.

Edit: just realised you did 870 to stop the internal tone mapping right?

It doesn't stop it but it is to choose the best curve the TV offers internally. It maps very close to eotf on our c8. And prevents the TV from clipping. You may have to experiment a bit with the c6 to see if it responds the same or needs a lower target nit.

Excellent thanks! I just tried it on my C9 and on the jazz demo it did wonders! Even though I really like the C9's HDR performance, nice to squeeze that extra out of it.

So far the R13 curves remain my favorite, they are however extremely close to Fer15's new "low consistent" for everything below 10 000 nits.
R13 is still brighter in places and the difference is noticeable in HDR.

There's very little difference in highlight detail preserved, and the only I've found were for low nits (509 curves) at 130 DPL. R13 still has better contrast although it darkens shadows a little.

At this point I'm just trying to hypertune it as much as I can, and waiting on Fer15's opinion about it.

Thanks for keeping the spirit alive! I'll take a look when we will have a useable build (e. g. with an option for brightness normalisation).

The C9 and newer give you a few more options if you calibrate the panel. Because with those newer models, you can actually measure your peak luminance and create a curve to match on the panel. Then if you set madvr to tonemap to that measured peak, it should follow eotf to that point and wring every ounce of luminance you can drive out of that panel.

I like R13 a lot myself. I've not tested Fer's curves yet. I will be watching a movie tonight so perhaps I'll throw it on there and see what it looks like. Did you modify it for 870 nits by chance?

EDIT:

Just saw r15 and grabbed that. That's what I'll be using tonight. Thanks!

I know everyone keeps complaining about brightness normalization but everyone seems to fail to understand WHY he put it in there. It's so that people don't have to try to figure out brightness matching to compare curves. That option is not likely to be permanent once the curve(s) are selected.

There isn't a huge difference between R13 and R15 FWIW, it's mostly gonna be a difference for 10 000 nits and to retain contrast better instead of being flat.

Well, we're at that point and that's where we want to be. That's seriously a good thing.

quietvoid, I did some more testing on my C6 with the default settings you gave. With the Spears and Munsil benchmark disk it's night and day! The detail increase is huge. Now most movies have very conservative HDR grades but good to know it's there for when they don't! It's a bigger difference than I got from doing a 3DLUT in SDR, which I thought was a game changer. For anyone that's on the fence like I was about MadVR with OLED's give it a shot, you'll be thankful you did.

Compared to the TV's tonemapping, it's definitely an improvement.

I've switched to my R16 (see signature) and changed my settings a bit: https://postimg.cc/1n14s6NB

I enabled contrast recovery because the improvement is significant even at the lowest strength.
There's slightly more blown out small highlights but the brightness is increased, and I most likely wouldn't notice the difference in highlights.

Bumped up DTN and lowered FALL highlight mod.

I'm still really conflicted with the desat lum method.
sep improves brightness and contrast significantly in S&M but I also absolutely can't stand how fires lose detail and saturation.
However it might end up being the leftover option since everyone uses it.

Hopefully the denormalization doesn't require too many changes.

I was noticing the fire issue last night, as well. This may be something madman can address down the road when we get back to that. Interesting changes you've made to the settings, though. I'll check them out later, as well.

Another day another curve..
R17 is my most accurate curve yet, since it doesn't alter shadows much if at all.
I've compared against clipping and most of the time R16 has slightly brighter shadows, reducing contrast.

R17 is also slightly better with highlights, as long as other FALL/DTN options don't blow them out.
All this isn't very noticeable at high nits and HDR, but it's good to know that it's tracking PQ correctly.

Tweaked the settings a bit just because, I guess: https://postimg.cc/303ZkP1w

Thanks quietvoid, really excited to watch my first full HDR movie with your settings! - out of interest are you using v130 for watching content on your OLED or just testing? I flipped my OLED watching machine to v128 due to brightness norm and my PJ is on v130 as it's only 95nits peak
