Settings to get better colors

[dawiinci]

I am using the latest HyperHDR 18.0.0.0 and HyperSerialESP8266 6.0.0.0

A Feintech Splitter sends a scaled version of 4K HDR 60 to a MS2019 grabber (USB3 fake version). LEDs are SK6812 RGBNW. For the grabber I use the provided LUT table, which is loaded properly. HDR mode is enabled.

I am not very satisfied with the colors though. Blue is often too greenish and dark areas appear in saturated green. White is very bright and colors are sometimes very subtle.

What are the perfect default values for everything to start with?

Probably it's best that you should generate your own LUT table. In logs you can find calibrated colors laters.

[awawa-dev]

And make sure that you set MS2109 properties as it is described.

[dawiinci]

Thanks, I will try that - need a windows computer first to output HDR. Is this a fully automated process?

I also can't set the hardware settings, or what do you mean by setting the properties as described?

[awawa-dev]

These controls are not supported on macOS. You need to create your own LUT using MS2109 default brightness/contrast/saturation settings.

[dawiinci]

Ok, so I will make my own LUT using the LUT calibration by connecting an HDR capable Windows device.

Anything else I need to set/change?

[awawa-dev]

It's best to use clean HyperHDR configuration. Only change USB grabber resolution to 1080p or 720p and format to YUV or MJPEG depending which you use. Probably macOS HDR can also be use instead of Windows HDR but didn't test it. https://support.apple.com/en-us/HT210980

[awawa-dev]

Using default MS2109 brightness/contrast/saturation settings you will probably receive a score around ~7000 after the calibration (because of disturbed captured stream). Not great but still better than using prebuilt LUT tables.

I can’t make it work. As soon as I connect to the grabber I don’t get HDR, even though it works on Apple TV.

[awawa-dev]

MS2109 doesn't support HDR (unless it's forced to process it) and causes all the setup including TV to fallback to SDR.
But most of HDMI splitters can overcome that problem when properly configured (can ignore the weakest device EDID requirements like MS2109 in this case).

[dawiinci]

That helped, thanks. I set it to copy.

I can only do it with NV12 though, because the resolution changes to 640x480, even if forced to 1080p . But in that mode I get green leds in dark areas. Is that normal?

It also looks like with gamma 1.8 with all colors I get better colors.

[awawa-dev]

Are you sure you changed the resolution using the grabber helper (yellow button next to the selected grabber in the device list)? Because it seems you selected wrong/forbidden combination of resolution and refresh rate so it switched to default 640x480.

Just after the calibration is finished, please switch to the Logs tab and copy&paste the output here. It's important.

You should use 1920x1080 NV12. That's how it looks for MS2109.

But it was and it caused all the story

OK, I'm done.

[dawiinci]

So that was reset shortly after switching the input, but I also get the memory leak when it is selected.

"Output path" equals deviceName, right?

[dawiinci]

Might the memory leak be because of M1?

[awawa-dev]

There is no memory leak for Adalight USB serial driver and macOS. HyperSerialWLED was used here to verify the transmission.

[dawiinci]

Sorry, but I experience a memory leak every time I switch HDMI. It first gets slow and then crashes eventually after filling up almost 15 GB of RAM.

After I restart the app it works again.

I guess I will quit and open the app when needed.

I now switched from tty to cu. Maybe that helps?
