If this is a Thunderbolt Display whose hydra cable has two heads, you must use the Apple Thunderbolt 3-to-2 adapter, or a similar third-party adapter (of which there aren't many).
You cannot use a USB-C to Mini DisplayPort adapter. The plugs and sockets may physically connect, but you'll present the monitor with the wrong kind of signal.

You also need a TB2 to TB3 adapter.
