If your MacBook Pro M4 / M4 Pro dual-monitor setup broke after working fine, the cause is almost always a recent macOS update or a cable/dock issue. Diagnostic order: 1) macOS update - System Settings → General → About → check current version. Open Software Update for any pending patches; early macOS 15.x had a Thunderbolt handshake bug fixed in 15.2. 2) Cable: try a different Thunderbolt 4 / USB4 cable. Charge-only USB-C cables won't drive a second display. 3) Hub or dock: if you use one hub for both monitors, you've hit Apple silicon's MST limitation - connect each monitor to a separate port on the MacBook itself. 4) PRAM/SMC reset (Apple silicon: full shutdown, 30s, reboot). 5) Detect Displays - System Settings → Displays → hold Option, press Detect Displays. 6) Specific app blocking second display - quit screen recorders and DisplayLink drivers.
Still broken? Bring it to our Dubai workshop with the cables and dock for a free test.
