thank you for your replay & hopefully madshi will add it asap

question about HDR tone mapping, for monitor without HDR support, but with DCI-P3

I bought a 32" monitor and found out they just rolled out a newer model (like under same price lol), both no HDR supported, meaning 300cd/m2 max, but the newer added DCI-P3 gamut, they are basically the same panel but the later one has the DCI-P3 option (92%) besdies sRGB etc.

my question: the monitor I bought which is the older one, no DCI-P3 menu

when we enable the tone mapping, what if a monitor that can enable DCI-P3 in the menu (in monitor's own menu), will it get better result, than the old one, bascially the same panel?

Exactly! Thanks for explaining my bad English.
By the way, this bug allows you to set the bitdepth of dithering other than the bitdepth of the madVR output. For example, you can do 8-bit dithering, but transfer the necessary 10 bit stream to AMD API (AGS) for the correct output of HDR, if I'm not mistaken. The statistics window show this.

My SDR 32" monitor might reach 95% DCI-P3 after calibration, and does not have any menu settings.
So I guest you can try to change madVR settings for DCI-P3 in calibration tab to see if it can get some color enhancement.

Can someone share the best way to watch HDR via madvr in LG C9?

What is the optimum setting?

Any solution on too bright subtitle using xysubfilter and asssubfilter? How do we dim this?

There's a reason "best" kind of posts are not generally considered useful. The settings for HDR are subjective. HDR in madvr is a rather complicated topic right now because the last official release is well over a year old now and doesn't have any of the enhancements to HDR that's been done in the test builds since that time. And those changes are nothing short of remarkable. There's a lot to set up and configure because they are test builds that are designed to test various parameters of the new Histogram Tone Mapping algorithm. People have posted screen shots of their various settings for different display types in the madvr test build thread on AVS. Find one that matches your C9 and start there. But this is not a "flip a couple switches and you get the absolute best quality" kind of thing right now. It'll get there, but, everything is in flux with the test builds.

I have i7 7700k and a geforce 2070 super using the latest game ready drivers and the playback isn't smooth on my lg c9 in madvr despite the low rendering times. I'm using full screen exclusive and I keep vsync activated globally in the nvidia control panel. Is anybody else having issues with rtx cards with the latest game ready drivers?

There was already an issue with LG C9, but not about "smoothness", but about wrong blacks, see also here:
AMD, Intel and Nvidia driver issues and last recommended version
click link for more info in line of 441.20.

But there was/is also a stutter issue with RTX cards, for the workaround see the second Note before Nvidia driver history. Hope it helps

Yeah, they fixed the black issues on the latest game ready drivers. I'll try out those settings in nvidia inspector when I get home and report back. thanks!

Someone else suggested using dx 11 native instead of nvenc, which doesn't make much sense to me.

"Set your video decoder to D3D11 Native (Automatic)."

cuvid is not in an optimal state it currently has no real advantages over dxva2 copyback but disadvantages.
nev had some ideas with it that would be really cool but that doesn't mean he will do it.

Okay, ill go back to using dxva2 copyback I was using that with amd, I thought I was suppose to use cuvid with nvidia cards.

kinda like a d3d11 native with cuvid it's been a while and i don't known if he tested it if he still thinks it maybe worth it but that would be the best decoder available with just one major issue.

it's not worth it if i talk about it.

What are the minimum GPUs required from both Nvidia and AMD that can do NGU image upscaling from 1080p to 4K?

The suggestions helped for smoother playback and even lowered my render time a bit. I still get 1 repeated frame every 8 minutes or so, but I’m getting no dropped frames.

Is repeated frames something we just have to deal with or are we suppose to get 0 repeated and dropped frames for an entire film?

most if not all 4k HEVC GPUs can do this, it depends on lots of factors, too many to mention. If you want to throw default MADVR settings at a full bluray 1080p remux with NGU AA every card will play the movie but some will run hot and loud.

If you are on a budget i'd reocmmend a used GTX 1060 or a RX580/590.

The GTX 1060 is a better performer in NGU so if you are not playing 3D MVC movies this is probably the better choice.

The new AMD 5700 or XT is the best current choice for AMD users who need 3D but if you are on a budget look for a used RX580, this is what I am used, I can use NGU AA at medium and also do a bit of tone mapping keeping rendering time around 30ms, however I more than often run it at LOW to keep the noise down as my card can be quite loud,

Like gaming, the more you spend the better the card will be, just throw as much as you can at the GPU and then tweak it to get the most out of it.

This is normal and not the result of render times. Either you use Smooth Motion or you match the refresh rate of your display as close as possible to your source content using madVR's 'custom modes' menu within 'display modes' under 'devices'

Have to say, looking forward to the next public/official release - Neo-XP's latest curve over at AVS is quite phenomenal.

I'd wait and see if anyone will test the GTX 1650 Super launching today, it's cheaper than GTX 1060's original US$249 MSRP at US$159 and Turing is certainly better than Pascal at compute workloads.

Isn’t this something variable refresh rate should be able to fix? I’m using a c9 with a GeForce 2070 super, and I have variable refresh rate working through “gsync compatibility.”

Of course my card can only do 60 hz at 4K since no hdmi 2.2 output, but shouldn’t this fix it when we have hdmi 2.1 cards?
