MadVR in use with LG OLED Thread

[ashlar42]

just use 120.
That makes TrueMotion "Cinematic Movement" ineffective. And I prefer to have it active... shame on me :D

[purplebaby]

I'm just wondering what the best settings are for madvr, from a quality perspective, for use with 2160p (often HDR) material. Using a 3060 Ti + LG CX via HDMI. Scaling algorithms etc? Are they in use for 2160p material on a 2160p display?

What about beta version 166?

Follow the madvr link in my signature.Hi Chros, could you be so kind as to update the HDR settings to the latest beta in the screenshot you publish in that link? Thanks in advance.

Hi,

I have finally got hold of a decent graphics card, and I'm playing around with MadVR, practising on my LG OLED prior to getting my Sony projector. I have done a lot of research and I would just like to confirm something.

I select 'MadVR tone mapping using pixel shaders' I do not have Windows 11 in HDR mode. I also do not tick the box 'send HDR metadata to display'.

I read on a lot of forums that if I did tick this box then the HDR flag will be displayed in the top right corner, which it does. However, the consensus is that this will result in the LG display tonemapping the already tonemapped data that MadVR has processed.

So my question is should I refrain from switching the LG OLED in to HDR mode and let MadVR tonemap the HDR metadata whilst the LG display remains in SDR mode?

[quietvoid]

The answer depends on whether you want to playback in HDR or not.
If you tone map to low brightness then it's fine to leave it in SDR, otherwise it would be inaccurate.

There are many ways to avoid the TV double tone-mapping, it depends on the model.
Since 2019 you can change the tone map curves to clip instead of rolling off.

Just got RTX 3080 FE as a replacement for my 2060, I noticed flickering is happening a lot. Its like changing refresh rate. My 2060 does this once or twice once you booted the system

Is there a tweak u can suggest to minimize flickering?

I have an issue with stuttering on 4K HDR MKVs with RTX 3080, Marantz SR-6011 and LG OLED65B8. 1080p SDR MKVs are fine. Latest madVR, LAV filters and Nvidia 531.79. Win 10 22H2. Zoom Player and MPC-BE.

Every half a minute or couple of minutes, the picture stumbles / stutters / jumps a few frames. Sound is fine. madVR display info doesn't show any frame drops. The issue is random and and always occurs at different time stamps.

With the same setup and a GTX 980, SDR and HDR were fine. Then I changed to a RTX 2070 Super. At first everything was fine. Then with around Nvidia 512.x and/or a Windows update, SDR and HDR were constantly stuttering. This was solved by:
- Vertical Sync to 'On' for the media player exe.
- In the madVR settings, uncheck 'enable automatic fullscreen exclusive mode
- In the madVR settings, how many video frames shall be presented in advance' to 1

Now with the RTX 3080, what else can I try to solve this stuttering with HDR MKVs?

1. Have u tried using DDU first before installing new driver?
2. Try clearing Windows cache with "BleachBit" and the built in Cleaner
3. Use certified HDMI 2.1 Cable
4. Try PotPlayer

Any owners of a g3 and 6900xt here? I am having a problem with hdr... madvr apparently can't switch to hdr mode for some reason after changing my tv; it did with the old one. I am using win11 (HDR off in display settings), mpc-be, lav filters, xysub, and madvr. I tested with MPC video renderer and it switched to HDR as expected.

[huhn]

win 11 and madVR on AMD yeah... the pain it comes back.

you need the newest beta that fixes a bug for the device page it may just think it can't do HDR.

well you are using AMD and to make the AMD HDR API happy you need to make sure that you are sending 10 bit in d3d11 on a fullscreen surface (windowed fullscreen is fine too).

[strumf666]

Newest beta drivers you mean? I am running 23.5.2; I had to disable 10bit pixel format (in amd drivers) in order for the windows display settings to detect the HDR capability of the LG, which is weird, because with the sony it worked regardless.
MadVR reports AMD HDR mode, but it cleary doesn't put the TV in HDR mode, except on some random occasions when I move the mouse to the bottom and the player ui appears.

[huhn]

madVR beta.

[strumf666]

I am using madVRhdrMeasure166, or is there something more recent?

[Klaus1189]

Why not use latest stable for HDR passthrough?

[strumf666]

I suppose I could retest, but I switched to the beta ~3years ago because stable version didn't switch to HDR properly with my setup.

[huhn]

you need one of the newest beta to stop the win 11 bug.

[strumf666]

I am using madVRhdrMeasure166, or is there something more recent?

you need one of the newest beta to stop the win 11 bug.
Am I using the correct version?

[huhn]

how should i know if it is 3 years old no.
the newest version that has a win 11 fix is not even 6 month old here.
https://www.videohelp.com/software/madVR
should be the beta from here.
it will stop working in a couple months... so that's that.

[strumf666]

Ok, this is the same version I am currently using.

[huhn]

so you installed the beta version of that page over your current 92 version 3 years ago even through it is not even 6 months old?

[strumf666]

No :) I started using madvr beta versions approx. 3 years ago, I upgrade when I get the expiry notification.

ASBL has been a serious pain in the butt for years on my C8, however I never wanted to risk the warranty since I paid for an extended package and could actually get a store credit for that amount ($380 CDN) if I never use it. Major selling point for the store I bought it from since it was still the cheapest place to buy the TV (BestBuy was the same price). It has now been 4 years and I have cashed in that credit (My brother bought an $800 AVR for $420!!). So, it was finally time to try and turn that ASBL off! I have no service remote, and all the apps I could find for my Android phone (with IR blaster) were behind a paywall... argh! But I stumbled upon a way to get IN-START sent to the TV for free!

After trying to edit existing free remote buttons to send the IN-START command and banging up against walls, I downloaded irplus - Infrared Remote from the Play store and discovered that it used WINLIRC_NEC1 codes! I had found a site with all kinds of codes and remotes to access the service menu, and one of the sections was LIRC/WINLIRC, so I loaded up some generic LG "Full TV Remote" picked the "1" button and edited it to the IN-START code instead of 1... and boom it worked!

Here is the WINLIRC_NEC1 code that sends IN-START to the TV: 0x20DF 0xDF20

One nice thing about this way of doing it, there is zero chance of hitting IN-STOP since the remote doesn't even have it on it :)

Anyway, I just thought I would share for anyone looking to do this totally for free.

[strumf666]

I figured out what the problem was... I left "the native display bitdepth is" to "auto"... When I set it to "10 bit (or higher)" hdr started working.

I have no service remote

[QBhd]

I did see that in my hunt, but it seemed overly complicated and I wanted something simple to use with my phone... I have even further simplified things since my post. I created my own "service" remote with irplus. It has just TWO buttons, IN-START & EZ ADJUST

irplus - Infrared Remote is a pretty cool app:

Is there a way to get older LG software versions (for my OLED65B8)? On the LG page (https://www.lg.com/uk/support/product-support/cs-OLED65B8PLA/), there is only 05.50.15 available.

I upgraded via USB stick from 05.40.09 to 05.50.15. Now RGB Full 10bit is not working anymore with my RTX 3080 -> no picture on TV. Only YCbCr 8bit is working. RGB Full 10bit was definitely working with 05.40.09.

[SamuriHL]

Even if you could, you can't downgrade, so it's irrelevant.

So it's true that LG plugged the downgrade loopholes with the latest software versions? That the downgrade option in for example ColorContro (https://github.com/Maassoft/ColorControl)l doesn't work anymore?

[SamuriHL]

As far as I know, it does not. But if someone knows different they can correct me.

I'm experimenting on the 100 and 120 refresh rates. I noticed that the image aspect ratio changes. What would be a good configuration such that aspect ratio remains the same

Longtime lurker here. With how quiet this thread has been lately, I'm curious if others are still using MadVR with their LG OLEDs, or if most have moved on. Have the native HDR tonemapping algorithms on newer TVs become good enough on their own? I'm still happily rocking a B8 with MadVR doing HDR to HDR tonemapping, but with the Plex for HTPC application apparently adding support for HDR switching on Windows, I'm tempted to try that instead.

Still using madVR with Kodi DSPlayer, as you seemingly do (your signature).

I strongly hope things will be finalized for HDR and that a stable version will be released for PC. It will probably be monetized somehow and if the price is reasonable I will definitely buy it. If it's sold subscribtion-based... not so sure, but for continued development it might work. In that case I would expect further developments, though.
