Whether you're coding, creating, or multitasking, connecting your MacBook to many external monitors can significantly increase your productivity. However, when only one external display is detected, many MacBook users become irritated.
Don’t worry if this seems familiar—the proper docking station configuration is frequently the answer to this problem.
Why MacBooks Show Only One External Monitor
The model and chip of your MacBook determine why it only shows on one external monitor:
-
Apple Silicon Restrictions
Only one external display is supported natively by base M1 and M2 MacBooks. In contrast, two or more monitors are supported by Intel, M1 Pro, and M2 Pro/Max versions. -
Docking Station Compatibility
Your MacBook may only be able to use one display if you use a basic USB-C hub without the necessary support. -
Cable or Port Problems
The second monitor may not function due to HDMI 1.4 vs. 2.0 limitations, poor-quality cables, or improper port connections. -
Software Settings
It’s occasionally necessary to adjust macOS display settings to recognize multiple displays.
How to Fix the One-Monitor Issue
To enable dual-monitor capabilities on your MacBook, follow these steps:
1. Verify the Model of Your MacBook
-
Intel, M1 Pro, M2 Pro, M1/M2 Max
Two or more monitors can be supported natively. -
Base M1 or M2 MacBook Air/Pro
To connect a second monitor, a docking station with DisplayLink functionality is needed.
2. Make Use of an Appropriate Docking Station
The key is a top-notch USB-C docking station with several USB ports, Power Delivery, and 4K HDMI output.
For instance, the LENTION CB-D53 keeps your MacBook powered and your desk clutter-free while offering everything you need to connect two monitors and accessories.

With a docking station like this, you can easily connect multiple monitors without worrying about MacBook port limitations.
3. Install DisplayLink (If Necessary)
To activate a second monitor on a base M1 or M2 MacBook, download DisplayLink Manager.
Your second screen should turn on when you connect the displays using the docking station and launch DisplayLink.
4. Modify the Display Configuration
Go to System Settings > Displays to:
-
Set up your screens
-
Configure the main display
-
Change the resolution and scaling to achieve the best clarity
5. Examine the Ports and Cables
-
Make use of premium HDMI 2.0 or DisplayPort cables
-
Connect displays to the docking station instead of directly to your MacBook
-
Verify that all cables are securely plugged in
