I have two old thunderbolt displays that I've used for the last 5 years with my iMac Pro. I had to purchase adapters but they've always worked. I just purchased a brand new Mac mini and although the machine shows my monitor on the displays panel inside the settings, the monitor is black with no picture. Did you have this problem when you first connected yours or did they just start right up?

Mine just showed up and worked perfectly

Has anyone tried to hook up 2 x 27” Apple Thunderbolt Display to the Mac Mini M4? Is it just plug and play from two T3 to T2 adapter? Thank you in advance
 
I've got one 27" Thunderbolt display and one 27" Studio display connected to my M4 Mini, so I would expect that 2 x 27" Thunderbolt displays should work just fine.

Thank you. The Thunderbolts I have are connected together with a daisy-chain and only use one T2 port. I ordered two T3 to T2, but I'm not sure if it's possible to connect them individually or do they have to be daisy-chained?

They should still work when daisy-chained. But individually should work too.

Mine shows up. But occasionally when I use the monitor on my MacBook Pro (14" M1 Pro), I need to allow it to connect from a little window that pops up before it will display anything.
 
I am using 3 Displays, 2 Thunderbolt and 1 Cinema with the Adapter from Apple, works, But one of my Thunderbolt Displays shut down at several time, most only for seconds but sometime komplett, Than I must disconnect the display and connect again, sometimes using the other Adapter. Sometimes USB is lost at the monitor, coming back after minutes. Cause there is no resetting the Parameter-Ram on the Mac mini m4 the M4 always know the first Connection.
The best I realized , the Cinema-Display got usb without connecting USB, crazy. I think the tolerant of the Parameters Apple is controlling are to small. I am thinking to make Sequoia new to get new Parameters. I love Apple
 
I'm so glad I Googled this.... got a shiny M4 Pro mini at home and been using it with a crappy Dell 24' but we have 10 Thunderbolt displays lying around in storage so checked one out to test at home tonight!!

Update for those wondering: My equipment: Mac Mini M4 and two 2015 Thunderbolt Displays. Purchased two original Thunderbolt 3 to two adapters from Apple ($49 each) and plugged both screens directly in to the Mac Mini and they instantly worked. Thanks all!
 
Does anyone experience this problem with the Thunderbolt display on a M4 Mini? In my case a drive connected to one of the USB-A ports on the back of the monitor will drop out after a period of inactivity, giving the system error message about properly ejecting the disk. The drive will then remount automatically until it disconnects again a while later. Overnight, for example, it happens 4-5 times with a stack of the same error messages waiting for me in the morning. Changing drives or cables makes no difference, but same drive connected directly to a port on the M4 Mini is just fine. Anyone help?
 
look at #34 from me. I disconnect all and change the 2 TB Display, right and center. the Main-Display with TB3 to TB adapter in daisy-chained with an Belkin TB1 Dock and Cinema-Display backside n TB4, the 2. TB Display with adapter on TB4 backside. Now the disconnecting of the one Display is gone but the ports of the Belkin-Dock slow are the same as you told. I am waiting for Satechi-Dock to get USB-A and 2 TB storage on the 3. TB4.

I am unsure how your problem relates to mine. In your case I would simplify the setup first. Remove the Cinema display and test with the two Tb displays only. Does that work reliably? Do you experience the USB dropout that I describe when connecting a drive to a rear USB-A port on a Tb monitor?

You don't specify the topology of cabling your three monitors. Are the two Tb monitors connected in series from the one Tb port ("daisy chained") or are they connected in parallel to two different Tb ports on the Mac Mini? How is the Cinema display connected into the Tb setup? I have no direct experience of three monitors on this computer, but the online information suggests some restrictions on the topology.

You say "USB is lost at the monitor", but both types of monitor have rear USB-A ports. Which monitor(s) are you talking about?

Thanks for the details. It seems your setup is more complicated than mine. I don't really have the knowledge to solve your issues.
