Not yet and reluctant to be honest, i've been having an odd problem since I tried multiple driver versions the other day, its shafted my pc a bit. I was getting a red cross on my speaker task bar icon every reboot suggesting the win audio service wasnt fully started when my PC booted, this turned out to be an issue with the win audio service not have service rights to some of the MMdevices reg keys, I think I have this fixed now but it has cropped up again randomly a couple of times now. My second issue is really odd, sometimes when I turn my TV off my PC just stop responding, nothing in events, no network nothing, its like it goes to sleep and wont wake up but the fans are still running and HDD lights are flickering like its doing something. I went back to 18.2.2 to see if this solved this, I havent tested it yet, I want to get stable again before trying this new driver.

I'm creating 72hz custom resolution and I was wondering which way is better - via nvidia control panel or via CRU. I'm using nvidia drivers 385.41

[Asmodian]

I only use CRU as a last resort. Custom Resolutions are still a bit... unstable... and I don't think we have a good "this way works better" figured out, it seems to vary based on system and driver versions without a lot of patterns.

I got a new SSD recently, so I reinstalled Windows (1803) with newest nVidia drivers.
I used to use nVidia custom resolution to get perfect 23,976Hz. But now, custom resolutions don't work. Maybe that's because they improved 23,976 (still not as good as "my" 23,976), maybe it's a new bug.
In the end, I use CRU to delete some resolutions (allowing me to avoid black screen when I switch my preamp on) and no nVidia custom resolution (since it's broken) so I have a frame repeat every 11-12 minutes. I'll live with this. :/

Installed Build 1803 today, tried the latest nVidia drivers and still the same mess with the JVCs (video levels botched in 12bits, HDR botched in 8bits etc). Back to 385.28.

You are probably right, but I hope other users will share their experience with the custom resolutions.

I had custom res' working but at some point in the last couple weeks after an upgrade it stopped working. I'm in the same boat with the 11-12 minute frame repeat that we get by default now. It's better than it used to be.

MadVR custom res still work fine here: 2160p@23p, one drop every hour or so using the EDID/CTA parameters of my JVC.

That's with 385.28. Last driver that works perfectly here with my JVC.

Only downside compared to the 398.xx is the 3D (1080pFP) which has a frame repeat every 3mn vs 13mn. But this improvement isn't worse all the other issues with custom res, bit depth, HDR in 8bits, levels in 12bits, etc.

Some of these issues are JVC specific, but still, too many things are broken with more recent drivers. I'm going to stick to 385.28 until a JVC owner reports that a more recent driver works perfectly. No point wasting time installing/uninstalling with each new version.

On Samsung TVs there's a special display mode to simulate HDR effects on SDR content called HDR+. It is used together with a function called optimal contrast.


Can we get such a feature for madVR? I guess those calculations done on the TVs are pretty low in quality?

+1 for that, ummm, more toys

(and we're back lol)

Well things are about to radically change for me. Tomorrow my new lg c8 65 and pio receiver will be here so I'm moving to 4k finally. I'm actually very glad the forum is back because I'm sure I'm going to have a few questions getting everything set up properly in madvr. No more 3d to worry about for me.

You are about the fourth person who has reported issues with custom resolutions with the new driver. I tried three methods and gave up before returning to the previous working driver and applied a saved optimization from madVR. You will likely be able to apply the EDID and nothing else. Whatever new optimizations to clock timings that were made may have broken custom resolutions.

Creating HDR content requires careful grading, so I can't see real-time HDR grading as being a great idea. Colorists don't always manage to get this right with better source material and careful adjustment. I think you can get a similar effect in Windows by leaving the OS HDR switch toggled on at all times.

[Asmodian]

Custom resolutions are very strange, I just created and optimized a new custom resolution for 24Hz with madVR and Nvidia drivers 398.36. No issues at all, I have over 5h reported without frame drops or repeats.

[arrgh]

...upps... I thought this is the madVR-Forum... but obviously it is a Nvidia-forum...

[LigH]

Once upon a time, I subscribed this thread to get notified of new versions of madVR. But since I have no HDR content and no 10 bit displays, this becomes more and more irrelevant to me. And my only issue I have with madVR (several seconds of blackness at the beginning of every video) gets buried under tons of issues which don't touch me; I may even abandon it...

[JarrettH]

madshi puts out solid releases. I don't have HDR either and haven't moved from 0.92.12

Yea, it's going to be interesting and I have a whole new situation to attend to as I just upgraded from my Panasonic plasma to an LG C8 OLED. Once the receiver comes tomorrow I will start working on getting madvr configured for 4K HDR with my nVidia 1060. I'm sure this will be just delightful fun trying to get everything working smooth. LOL Now that I'm on 4K I may opt for a 11 series nVidia card when they come out. I'm sure getting 4K smooth on my 1060 is going to be a bit challenging but we'll see.

Stupid question time. How do you get the 24Hz custom res to stick the 23.976Hz timing? I tried this and when madvr switched to the 24Hz res, it literally showed 24.000.

[Asmodian]

I have no idea. It just did.

I opened madVR's settings while in 60Hz, double clicked the 23 Hz mode, selected my EDID, test, save. Then put 2160p23 in madVR's list of display modes and madVR switches to it perfectly.
