Display set up for Mac Pro

Hello, my company provided me with a Mac Pro computer and a Studio Display. I would like to add another monitor to my setup. I have a Dell Ultra 27" monitor, but I am unable to connect it to my Mac. Can you recommend a cable or suggest a better monitor option?


Thank you!

that shows:

resolution: 3840 x 2160 at 60 Hz


  • 1 x DP 1.4 (HDCP 1.4/HDCP 2.2)
  • 1 x HDMI 2.0 (HDCP 1.4/HDCP 2.2)
  • 1 x USB Type-C (Alternate mode with DisplayPort 1.4,
  • USB 3.0 upstream port, Power Delivery PD up to 90 W)


to connect with a USB-C cable, that cable must be certified to at least USB-C 3.1 SuperSpeed PLUS and show this logo or beer, and be ONE meter maximum length:



Cables "shipped in the box" are notorious for being 'lowest bidder' cables, and are often just good enough keep you from immediately returning the product.

The same rules we learned for the M1 and M2 still apply. Display interfaces are generated deep inside the system on a chip. How many there are depends on the exact type of Processor:


M3 (plain) like the 13-in and 15-in supports up to ONE fully hardware-accelerated external display.


M3 PRO processor supports up to Two fully hardware-accelerated external displays.


M3 MAX processor supports up to Four fully hardware-accelerated external displays.


In every case, turning off the internal display does Not allow you to connect another external display.
