MadVR PC what components do I need?

OK guys you have all given me the itch for MadVR that needs to be scratched so my question firstly is what PC components do I need to make up a PC to run this to a high level.

Once I build the PC then will be time enough to ask advice on how to set it up.

Epson EH-TW9400 - QualGear Fixed Frame 100” - Sony x700 BRP & Panasonic 420 BRP - Sony 1080 AVR - IPL Acoustics M1TLs & IPL Acoustics AVC Pro Centre, Four KEF surrounds & 2 Sub boxes (10” Sub + 10” Passive Radiator)

If you already have a PC, even with a weaker card, you can still test madvr, just not in motion (or smooth motion). Just pause the video and change whatever settings you need to compare it to the Epson's DTM.

@blastermaster do you know the nits of the screen?
With an Optoma HD3300 + Panamorph UH480 + 138" XD AT screen (0.94 gain) the estimated nits would be around 82 in High lamp and 72 in Low.

How many hours on the lamp?

Using a video player that's compatible with madvr, like MPC HC: https://www.avsforum.com/forum/26-ho...tup-guide.html

Install madvr: http://madvr.com/
Madvr folder must not be deleted, and not placed in Program Files or the Windows folder.

Install the latest beta: https://www.avsforum.com/forum/24-di...l#post59127786

Configure MPC HC (or other player) to use madvr as renderer as well as audio, color space (in madvr and lav filters), lav filters, etc.

Use these settings to start with, with the exception of display peak luminance: https://i.imgur.com/dmzMOX9.png
You can disable highlight recovery and shadow recovery in render times are too high. Render times for 24p video should be under 41ms. Render times can be displayed by activating the OSD by pressing Ctrl+J.
Change dynamic target nits to enhance the HDR effect (higher value), or bring the image closer to SDR (lower value). 50 is towards the lower.
Change contrast recovery to whatever you like, you can start with Hill Strong.

Choose the gamma curve: https://forum.kodi.tv/showthread.php?tid=223175&page=37
The gamma must be the same in madvr (the two places where it's found) and the projector.

This topic has also been discussed on this thread: https://www.avsforum.com/forum/26-ho...l#post58891882

This thread is for madvr tone mapping development, not support: https://www.avsforum.com/forum/24-di...ector-292.html

For the rest of the madvr settings, there are many combinations, but with an 970GTX try these:
madvr>
processing>artifact removal, image enhancement, image enhancements: disable all

scaling algorithms
>chroma upscaling: Sharp low quality
>SSIM 1D strength 50%

rendering
>dithering: Ordered Dithering

trade quality for performance>
check compromise on HDR luminance channel quality

You can also check scale chroma separately to reduce render times.

LE: for best performance in LAV Video select D3D11 and Automatic (native) for Hardware Device to use.

There is a mostly update guide on madvr, not sure if it's up to date on the DTM:

Why would that matter for video playback?

Well with that much lag you'd have to adjust the audio for sure. Then if you have 60fps content, you'd have to adjust it separately for that.

Yeah I have not noticed any difference in AV sync at 3 frames which completely solved any of my dropped frames on my RTX.

My Denon remains at 78ms.

How do you mean?

Windows can't process Atmos, it needs to be sent out to a compatible receiver.

What output range do you set with MadVR?

When. I set MadVR to 0-255, Nvidia to 0-255 and JVC NX7 to auto or 0-255, my black bars are all washed out and the contrast is very much lacking.

When I set MadVR to video and JVC to 16-235 then the contrast is much improved and the black bars appear deep black vs washed out grey when using the full range.

I am not sure why is MadVR not taking the video input range and mapping it correctly to the full range? Is setting the entire chain to 16-235 the right way to set it up?

ask other user of the PJ if full range works on that model (it should...) but what so ever setting everything to limited is ALWAYS wrong.

That is what I do for my JVC RS500. But I also have to send RGB 12-bit as the e-Shift models are unable to accept RGB 8-bit; the so-called magenta bug.

Hmm...I also run a RS500 but haven't used it much with the same madVR PC since the upgrade in October. I have to check it again.

I use madvr with the 1080Ti card and the JVC NZ9, I sometimes nootice when the image is all very black that I see some type of artifacts moving withing those black areas...
What might be wrong in my setip, is it dithering that causes that movement within the black image, Im using ordered dithering.

You mean JVC NX9? This is not dithering. You wont notice dithering. That's the point of it.
It sounds like you have a raised black floor and some compression noise you're seeing. If your black floor is low you won't see anything in black - its just black.

Sorry I mean the NX9, I never thought my black floor was raised as I set it with the blanking feature of the JVC NX9, but maybe you are right, I will drop it one notch and see if it stops. Thank you Mark

Im not sure what you mean you used the blanking factor on the NX9. What is the brightness set at? Can you instead throw up a black chart and set black to 16 so that 17 is *barely* visible (like so hard to notice you almost cant notice it).

Thats exactly like I set it, I have to put my nose to the screen to see 17. But sometime I check it by using the HIDE button on the NX9 and making sure thatblack is set the same when HIDE is open or closed.

OK. Perhaps the content, itself, is raised. Hide is tricky. The dynamic iris sets its level based on the unhidden content (at least it did).

If I ever test with HIDE I always turn off the Iris as I know that will certainly much up the readings...

hey there,

i have a pretty weird phenomenon lately... i'm not 100% sure but i think it started with the latest nvidia driver update.

following setup:

- win 10
- gtx 980
- latest mpc-hc / lavfilters / madvr
- philips 55pos901 oled

i've been using this setup for quite some time without any problems but i recently noticed wrong black levels for HDR content while SDR content is fine. (madvr hdr passthrough enabled)

rgb full range (0-255) is enabled in madvr settings and it currently gives me correct black levels for SDR content but i need to change it to 16-235 in order to get correct black levels for HDR content. (otherwise blacks are grey)

i checked this with some black level test files where 0-16 should be black and 17-25 flash.

0-255: correct SDR black levels but greyish blacks for HDR content
16-235: correct HDR black levels but bad black crush for SDR content

could this be a nvidia bug? or is there someting i am missing here?
