Apple 27" LED Cinema Display not working with Mac Mini M1 HDMI connector
Hello,
Just bought a Mac Mini M1 and I cannot get my 27" Apple LED Cinema Display (not Thunderbolt) to work with it on the native HDMI port using an HDMI to Mini Displayport adapter (I made sure it was not an HDMI to Thunderbolt adapter) I just purchased (see below for exact model).
When I plug the adapter directly into the Mac Mini's HDMI port, it recognizes the display correctly but the screen is black and does not show any image. I am using Apple remote desktop while debugging this issue so I can see what the system is seeing. If I then plug the HDMI adapter into Apple's USB-C Digital AV Multiport adapter, it also does not work.
But if I plug the HDMI cable into my Insignia 7-Port Type-C Hub the screen works perfectly fine. This is very baffling. I don't want to do Mini DisplayPort to HDMI to an adapter to USB c.
I want to use the native HDMI port directly and avoid any other adapters altogether. When I plug in my Sony A9 4k TV directly into the Mac Mini, it works great. Why would an old but very reliable Apple monitor not work directly and need a dongle from a 3rd party via USBC??? It's not 4k and well within the specs of what that native port can drive.
This adapter from Apple does not work: (model A2119, HDMI 2.0)

This adapter from Insignia works (HDMI 1.4)
