mac mini m2 pro 2 studio displays

Mac mini - Technical Specifications - Apple

"Two displays with up to 6K resolution at 60Hz over Thunderbolt"

+1 to @Malcolm, but IMO the spec is ambiguous: the section on dual/triple monitor support could be read as always requiring an HDMI monitor connected in tandem. In fact, HDMI is mentioned under all combinations, what’s not clear is whether it’s required or optional.

So, you need to synchronize your purchases so they can be returned within the window should they not work together as envisioned by you. You could also ask the store to hook up two monitors to the Pro and show they work together (but not sure if Apple will go that far to complete a sale).

HDMI is listed with all the different Thunderbolt display configurations because the HDMI capability depends on what other displays are connected. That doesn't mean that a HDMI display is required, it's just telling you what can be connected, not what must be connected.

I hope you’re correct, but there’s room for ambiguity: the “spec” (which is more a marketing sheet) could be also read as HDMI can’t be left non-empty under any configuration. Based on past complaints, it’s an invitation IMO for trouble down the road. Dual/triple = not Apple’s strongest suit or even priority. Buyer beware.
