How to Connect Dual 4K Monitors to a Thunderbolt Mac

Updated July 2, 2026 · ConnectWizard

To connect dual 4K monitors to a Thunderbolt Mac, use a Thunderbolt 4 dock that supports two 4K displays at 60Hz. Connect the dock to the Mac's Thunderbolt port, attach both monitors to the dock, and arrange them in System Settings. Thunderbolt's bandwidth handles two 4K 60Hz streams cleanly.

Yes, with a Thunderbolt 4 dock and a Mac that supports multiple external displays (M1 Pro/Max and newer).
