This is nice, but can I use it with an HDR monitor without forking over $7000 for an Apple Pro Display XDR? I haven't been able to confirm whether or not Mac OS Catalina actually supports any third party HDR monitors over HDMI. I have the Asus PG27UQ 4K HDR monitor and my 2019 MacBook Pro only outputs 4K 30Hz 8bpc over the official Apple HDMI adapter[1], while my 2019 XPS 13 2-in-1 outputs 4K 60Hz 10bpc over this same Apple adapter.

They mention the "LG UltraFine 5K Display" on the page, maybe it's the only one supported? Maybe there's more

  I have some sort of Dell at home that I believe I tested and works properly. But then again I’m using DisplayPort. I don’t know why people are so insistent on using HDMI and being surprised it doesn’t work as well.

    I save the DisplayPort port on this monitor for my Windows desktop because Mac OS doesn't appear to output the 4K 98Hz HDR that the Asus PG27UQ naively supports over DisplayPort 1.4.

Display-P3 is not HDR. It is just a wider gamut, so wider range of colours but otherwise still SDR. It has the same tone curve (gamma function) as sRGB.

Catalina will support any HDR monitor. You would just need a HDMI splitter and run it into your monitor. Alternatively, pop a Blackmagic Decklink 4k into a PCIe chasis and run it out of one of the thunderbolt 3 ports. I do this on my HDR OLED and it works nicely.

  Are you able to get a 4K HDR signal through the official Apple HDMI adapter to your HDR OLED display, or only through your Blackmagic Decklink 4K? I am using the official Apple HDMI adapter with the Asus PG27UQ.

    My Decklink Mini 4k was under $200 and does the job. I don't know about your Apple adapter. Were it not working, then I would look at getting a HDCP splitter midway in the chain.
