Ok so i will leave it how i have now cheers

Hmmm? I have a 120Hz native display. I use 1080p24 because that is the original mastered rate and I always match rates or judder is introduced. But because I always upscale, that resolution means nothing. 2160p24 takes its place. What that has to do with the 2160p25 I suggested, I do not know? Planet Earth II was originally mastered at 25fps. My display offers that frame rate so I can match it. Without matching it, uncontrollable judder and frame drops were introduced. So, I added 2160p25 to madVR's list of display modes and the new matched rate produced perfection. Why others recommend this is wrong and not to match refresh rates and instead double the resolution and mismatch it, I don't know? Perhaps you use 50fps titles although I've never come across one. Maybe you could explain? I suppose 2160p50 would still work because it is an exact multiple of 2160p25 but what would be the point?

Hi, well I can confirm it also happens in MPDN so MADSHI was correct in stating this was not a MADVR issue, it must be DIRECT3D11

However, who do we know that MADVR and MPDN are correctly operating with DIRECT3D11, perhaps they just both have the same problem, its possible.

No idea where to go from here though, at least the workaround is easy to use, just turn off DIRECT3D11 for SDR material.

Exactly because 25 fps fits into 50p without any troubles, and it avoids further difficulties when you hit interlaced material - like, for example, some of the older BBC documentaries like Frozen Planet, which after deinterlacing is 50 fps. So you are never left in an odd spot where the screen was switched to 25p because something didn't quite account for interlaced content (happens often with oddly flagged files), but madVR wants to output 50 fps to it.

At least on my TV motion looks absolutely fine running 25 fps on 50 Hz, and motion problems is the most obvious problem for me personally, I generally spot immediately if the screen refresh for some reason didn't change to the right one or anything like that.

So instead of trying to increase complexity by handling both 25p and 50p modes, why not simplify it by using one that works perfectly for both?

it's simple there is no spec for 25 FPS on blu ray or broadcast. edit: UBD has 25p support and internet videos doesn'T really care.
there are true 120, 144 and 240 hz screen (even 480 hz 480p test models). all of these will obviously run perfectly with a 24p source this played at 240 hz so this is not a mismatch and nones has recommand a mismatch here.

and there are native 60 hz screen that can display 24p properly so it's not that simple at least this part.

@mclingo
D3D11 is broken in MPDN and madVR using an AMD card and are working fine with nvidia and your TV does "stuff" do i really have to say it?

one thing is very very unlikely and that it is madVR related.

That makes perfect sense. I didn't realize there were such things as 50p. Since there is, indeed this is the best universal option and I will reco and update accordingly.

Thank you.

One reason to use 25p is for >8-bit support with a 4K screen... not very important in my option but it is a valid reason.

How do you use DEVCON ?
It's not a normal .exe called via Powershell ...

https://docs.microsoft.com/en-us/win...devtest/devcon

its just an exe.

here is an example command, I used this to manually drop into 23,976.

SETRES h3840 v2160 b32 f23

I have my default desktop settings at 60hz programmed my on remote, is handy when you lose HDMI handshake or when KODI doesnt drop back to 2160p properly from 1080p which it does on occasion.

Is there a guide or standard settings used for displaying HDR content on an SDR PC monitor? I've got a film to look pretty close to a 1080p SDR version by using:

- Convert HDR content to SDR using pixel shader math
- Display's peak nits: 100
- (All other settings default)

But it's still a bit washed out. I assume there's no "perfect" solution to this?

no there is no perfect solution the whole HDR topic is pretty much vivid mode without a clear spec. everyone pretty much does what they want with it.

increasing the peak nit should make it look less washed out.

Yeah default nits rating was changed because of this. Don't set to 100.

Hi,

Im testing the new DXVA11 native decoding with madvr and lav filters. I use Intel HD620 GPU, this is working. I used to use DXVA2 scaling for chroma and image bc this sufficed. With DXVA11 decoding the chroma and image scalers used are Bilinear. Is there a way i can get DXVA11 decoding with DXVA2 scaling?

No, not yet.
Refer to the release notes for the limitations:
https://forum.doom9.org/showthread.p...91#post1815291

Hopefully madshi finds some time soon to resolve those limitations, so we can recommend D3D11 decoding without reservations.

Another one: if you use motion interpolation from your TV. Better interpolation from 25p to 100Hz than 50p to 100Hz.

I'm confused. Increasing the "display's peak nits" setting in the HDR tab makes it more washed out for me.

Ok, so after matching refresh rate with movie rate by adding 23p and 24p to the string, i had time to watch few HDR movies like Lucy and Star Wars i noticed cpl issues :

1st im getting framed drops and repeated frames, which when i had refresh rate at 59hz never happened.

2nd thing now i have frame repeated every around 7.30min, when on 59hz i had around 44min.

Clock deviation is on 0.00000%

Didn't check yet any 1080p movies so can't tell if there will be same issues, so far only those 2 movies in HDR

So my question is why after matching tv refresh rate to movie such problem started to occur? and steps i should i do to try make this sorted.

btw. i have smooth option off if does matter or not in this situation, but from what i remember when i had on, there were issues with smooth playback

what i notice as well that :
- decoder, upload, render, present queue cant stabilize, i can see every few seconds changes there

cheers

Is diffuse white set to 100?
