M1, M2 or M3 MacBook Multiple Monitor Expansion

Are you using an Apple MacBook Air/Pro equipped with the latest M1, M2, or M3 chip and looking to extend your display with a dual monitor setup or multiple monitors to optimize your workflow and boost productivity? This article will discuss the challenges M1, M2, and M3 MacBook users may face when trying to connect multiple 4K external displays, and provide two cost-effective solutions to help you easily overcome the display limitations of Apple's M1, M2, and M3 silicon - enabling an extended multi-monitor macbook setup.

Challenges of Expanding Multiple 4K Monitor

A study by the University of Utah and Wichita State University found that using dual monitor setup  can reduce work errors by 20%, increase job satisfaction by 91%, and decrease work stress. This means that MacBook users can significantly improve their productivity and work efficiency by extending their display across multiple monitors. Apple's latest M1, M2, and M3 MacBook Air/Pro models excel in performance and portability, they still face some limitations in connecting external monitor.

On Reddit and forums, we often see Macbook users asking: Why don't the M1, M2, or M3 chip-based MacBooks support 2 or more external displays? The reason is that the M1, M2, or M3 chips only have two display output engines, with one always used for the internal display, and therefore they only drive one additional external monitor. This display limitation can cause inconvenience for MacBook users who need to multitask across multiple applications and resources simultaneously for tasks like photo/video editing or programming. So,how to extend display on macbook?


Cost-effective Ways to Expand Dual 4K Monitors on Apple MacBook Air/Pro

Even though Apple MacBook Air/Pro models may sometimes experience issues with macbook not recognizing external monitor due to certain hardware limitations in connecting external monitors, there is a cost-effective solution to enable a dual 4K monitor setup or multi-monitor display expansion - by leveraging DisplayLink technology.

DL-6950 series DisplayLink chip can achieve dual 4k60hz video output under USB3.0

The principle behind how DisplayLink technology enables multi-display output on M1 is similar to the built-in Sidecar feature in macOS. It simulates external display devices through the processor, compresses the image, and then outputs the video signal through the USB interface to the adapter, where the DisplayLink chip decodes and converts it for the HDMI output to the display. As long as your MacBook supports DisplayLink drivers, you can easily add extra screens or extend your desktop up to 6 displays total. However, if you want to achieve 4K 60Hz display quality, you'll need to ensure that the selected DisplayLink device and the USB port you use support USB 3.0 or higher.

For users with a limited budget who need to achieve a 4K 60Hz dual-screen extension on an Apple MacBook Air/Pro, the ACASIS 4K Display USB C to Dual HDMI Adapter with DisplayLink priced at $64.9 is the most cost-effective choice. This adapter utilizes DisplayLink technology to ensure smooth and high-quality display output.
