Depending on the model, Apple Silicon MacBook Pro officially accommodates between one and three external displays, but with a software workaround, you can extend that number.
The recently launched Plugable UD-7400PD dock utilizes this capability, offering an efficient solution for an M1 MacBook Pro to run up to five external monitors simultaneously.
External Monitor Support for MacBook Pro
Apple Silicon Macs represented significant advancements over Intel models in many aspects, yet the base M1 MacBook Pro was limited to just one external monitor. This stood in stark contrast to certain Intel models that supported up to four monitors.
Higher-tier models of the MacBook Pro could handle three external displays, but a software workaround allows even the M1 model to connect up to six monitors.
M1 Macs can indeed support up to six external displays with solid performance, based on early tests. The workaround is fairly straightforward: download the DisplayLink software for macOS and acquire a 4K DisplayPort to USB 3.0 adapter (or HDMI adapter).
Introducing the Plugable UD-7400PD Dock
You do not require dedicated hardware for the DisplayLink method, but you might find Plugable’s UD-7400PD dock appealing due to the diversity of cables and adapters it consolidates.
The UD-7400PD, powered by DisplayLink’s DL-7400 chipset, is the first docking station to enable up to five displays, including four 4K monitors and one 8K screen. Additionally, it provides 140W Power Delivery, ensuring that even demanding laptops stay charged during intensive tasks. Its universal compatibility makes it an excellent choice for mixed-platform workplaces and IT departments that conventional OEM docks struggle to support.
The dock also includes an intelligent splash screen that activates when powered on but not connected to a computer, displaying real-time status and asset information along with a QR code for setup and support resources. This innovation aids in setup and asset management, especially for IT administrators navigating flexible work environments.
The dock comprises three USB-C ports that support DisplayLink for up to 8K monitors, an HDMI Alt Mode port (also handling 8K), and an HDMI DisplayLink port capable of 4K output. The exact configuration depends on your monitors’ resolutions, allowing for combinations such as one 6K monitor paired with four 4K units.
Moreover, it features a 2.5Gbps Ethernet port, a USB-C port with 10Gbps data transfer and 30W power delivery, two USB-A ports supplying 10Gbps, and an audio in/out jack.
Lastly, there’s an additional USB-C 140W PD port that allows for a single-cable connection to power your MacBook while driving the monitors.
The dock is priced at $264.95. Though there’s currently no set release date, the company has indicated it will be “coming soon.”
