Thanks!!
You are playing 23.976 fps content on a display set to 24 Hz so obviously there will be dropped frames.

Set your display to 23 Hz (it's the windows name for 23.976).

At default 23 Hz you will still get a repeated frame every ~4.5 minutes. You have to create a custom resolution to get it right. Using CRU, I set it at 23.975 Hz, which gives me 23.97585 Hz. This produces a frame drop every ~56.5 minutes, which is the best I can get.

I have been using ReClock for years, but recently I kept seeing random frame drops which did not register on the madVR OSD. I decided to test the custom resolution with bitstreaming, which will be useful when I upgrade my audio setup (waiting for HDMI 2.1). So far I am pretty happy with the change.

I can turn on HDR in Windows and videos play fine this way, but that is a bit annoying. If I do not turn on HDR in Windows, the video is washed out (no tone mapping), but the madVR OSD shows it is playing in HDR. It shows NV HDR, BT.2020 and HDR, unkown properties (this is always like that).

Anybody else have this problem?
I got a message from Nvidia that HDR issues are being worked on. Will see what this means.

These beta versions are supposed to be unpacked on top of the last release version - files which didn't change are not included.

Also do you think I am good with 8GB of RAM or is there anything that madvr could do better with 16GB?
Finally here is a photo of stats while paying the movie.
I left Star Wars paying like one hour and when I came back there were 6 dropped frames. Am I somehow pushing it too far off is it normal to do drop a few frames here and there?

You want to get to the 23.976hz mode if the projector supports it.

8gb is enough, as long as it's dual channel.

Run 8bit 444 RGB Full, don'tuse 12bit on the jvc.

Run the 3D lut for SDR lut, select source colorspace dci-p3 or rec2020.

Before calibration, check that the gamma mode/setting from measurement that it's in is Close to flat 2.2gamma @ 6500k.

23Hz is obviously not 23.976 either.

I am going to play with CRU. I was in fact able to get the same as you just with the Nvidia Control Panel BUT for some reason, the custom resolution wont let me use 12bit only 8 where all normal resolutions allow me to use 12. Hope CRU does not have that odd issue.
Thanks!

Ok then I will save money..yes it is 8GB dual channel 1600 DDR3.

Any reason NOT to use 12bit with the RS520? From reviews I read it actually does 12 bit even if due to other things it ends up being 10bits. Just curious as to why this recommendation.

Ok I am going to try the 3D Lut to see what I get.
I did watch Star Wards yesterday and it was looking stunning, so much better than when I was using the projector HDR mode.
Thanks so much!

That is great but in reality, it does not. I would be very happy if it was giving me 23.976 I would have no repeating frames.

I have no repeating frames out of the box, well 11,6 hours, but enough for me on 23.976 files

Great but not everyone gets 23.976 by setting the card to 23Hz, that's my point. Good for you

There are custom resolutions that can do it for you as well

Of course, let me know if you want to know anything, perhaps I can assist.

Well, if you can tell me how to do it with CRU for my RS520 JVC then THAT will help me a lot. Or via Registry. I want to see if that allows me to still use the 12 bit option and bypass that dumb Nvidia bug :/

Wait for other users like Manni, he has a JVC projector and knows what he is doing.
Perhaps another JVC owner can also help.

Why do you want 12 bit output? 8 bit is fine.

Well I need to check with some tests scenes but I would expect banding at 8bit vs 12bits. I mean, there has to be a difference between 12 and 8 and 4K content, or not really? Just kind of feels like a waste if my display can do 12bits (well 10) to go with 8 lol
If not, I can just roll with what I have as it is with the Nvidia control panel custom resolution that get some close to 23.976

This is what you need to do in CRU, it is very simple. Make sure you export the original EDID first, in case you mess something up.

You can basically delete everything in "Detailed resolutions" and add the ones you need. You should only have two or three in there (but even the third one might not work sometimes). Most of common resolutions are stored in the extension blocks, so you will not lose anything by doing this. Resolutions you add here will appear as PC resolutions in the nvidia control panel.
23.975 works best in my case, it could be different in yours. Experiment.

12-bit works with this method, unlike custom resolution in the nvidia control panel.

I will try that and report back.
Thank you so much!
