I am thinking about getting a new M1 Mac Mini to replace an older 2013 iMac. I also have a 2 27 inch Thunderbolt display. My question is can I use both the Thunderbolt displays with the following setup:
Mac Mini -> Apple Thunderbolt 3 to 2 Adapter -> Thunderbolt Display 1 -> Thunderbolt Display 2
So basically daisy chain the Thunderbolt displays by plugging 1 into the other. Nothing I read says I cannot do this but want to double check.
I believe the original Apple Thunderbolt 3 to Thunderbolt 2 adapter is what you need for this case. You basically need thunderbolt connectivity for your Thunderbolt Display and not display port only. Thunderbolt display works only with Thunderbolt technology.
And if plugged ALONE into the USB-C port with JUST the T3-to-T2 adapter, YES, I can get my Thunderbolt Display to work. But I CANNOT get it to work along with the LG Fine 4K. I have yet to find a scenario by which I can have two monitors working simultaneously on my M1 MacMini.
To run two displays with a M1 Mac mini, one must be connected to the computer's HDMI port. There is no way to connect a Thunderbolt display to HDMI, so it must connect to one of the Thunderbolt 3/USB-C ports with a Thunderbolt 3 adapter (not a Mini DisplayPort adapter, even though the plugs fit.
The LG UltraFine 4K can connect to the HDMI port with a HDMI to USB-C converter:
This is not compatible with the LG 27" Ultra Fine monitor which is Thunderbolt only, but should work with your 4K 24" which runs via USB-C with or without Thunderbolt.
There are lots of adapters for connecting HDMI displays to computer USB-C ports, but they will not work in the other direction.
It seems there's a solution for LG Ultrafine 4k via hdmi as Maclom J. Rayfield suggested.
Check out this video with 2 LG Ultrafine 4k, one over TB3 and the other via HDMI with some cable adapters:

Problem is their resolution is not native, so don't know..
A Apple monitor will work with adapter to the usb-c port. You then must have a hdmi compatable monter for ther hdmi port. I have a GIGABYTE G27Q 27" 120Hz Gaming Monitor, 2560 x 1440 IPS Display which is excellent.
No possible, unfortunately.
Can you explain why? What if I had 2 T3 to T2 adapters vs daisy chain? Current 2017 macbook pro with T3 is able to work with a Thunderbolt display, is there some reason M1 Macs wont do the same?
You can try it...although there’s nothing in the Apple spec that says you can do this.
The Apple M1 spec makes no mention of anything but a single monitor over all its Thunderbolt ports. Good luck!
I see what you mean and obviously a bit of a risk, I did stumble upon a Youtube vid of 6 screens on an M1 Mac Mini but would seem odd if they limited it this way but will research a bit more.
Ok. Remember, “I saw it on the internet” won’t work with Apple Support 😉
As mentioned, I am thinking of buying it, not seeking support for something I have that does not work. It would be pretty nuts if Apple didn't support multiple displays on the new mac mini.
They’ll support but support doesn’t mean fix. A sympathetic ear, collection of logs, even a call from an “engineer”, that’s a given. Be happy.
Thanks, that helps. Very pleased with the Mini but what a shame I can’t use the iMac with it.
