I have recently purchased a Mac Studio and display but they do not seem to work. The studio white light is on, but nothing is happening on the display. When I unplug the display three white lights appear for a few seconds then disappear. Would be grateful of any advice on how to get this up and running. Thanking you in advance.
“Then plug in the included Thunderbolt cable to the Thunderbolt 3 port 
on the back of the Studio Display, and connect it to your Mac” - there’s only one on the Display:
What OS version is the Mac Studio running? Is it fully updated to Ventura? If so, I would schedule a Genius appointment with the nearest Apple Store.
Are you connected properly? Connect Studio Display – Apple Support (UK)
What display? Make & model.
Does this help? I’ve got a Mac Studio and Mac Studio Display. Both brand new
I’ve tried it in all four thunderbolt ports with no success. I gutless u could try it on my MacBook to see whether it works with that?
*I guess I could
