The MacBook Pro M4 Pro officially supports up to two external displays at 6K@60Hz plus the built-in screen. Common reasons both don't activate: 1) Both monitors plugged into a single USB-C / Thunderbolt hub - Apple silicon doesn't support MST splitting, so one hub can drive only one display. Connect each monitor to a separate Thunderbolt 4 port on the MacBook. 2) Wrong cable - USB 3.2 / USB-C charge cables don't carry video; use Thunderbolt 4 (40 Gbps) or USB4. 3) Closed-lid "clamshell" mode disables the internal display but doesn't free up an extra external slot - you still get two external monitors. 4) Refresh-rate mismatch - drop one monitor to 60 Hz to test. 5) macOS bug - update to macOS 15.2 or later.
Press Option-Detect Displays in System Settings → Displays. We sell tested CalDigit and OWC Thunderbolt 4 docks at our Dubai store.
