FAQ
How many external monitors can this Thunderbolt 3 dock support?
The StarTech.com TB3DKM2DPL supports two external monitors simultaneously. Both monitors can be driven at 4K resolution (3840 x 2160) with a 60Hz refresh rate via its two DisplayPort outputs, providing a high-resolution, multi-display workspace ideal for productivity and content creation.
Is this docking station compatible with Apple MacBooks with M-series chips?
Yes, it offers broad compatibility with Apple Silicon MacBooks. It supports dual external displays on MacBook Pro and MacBook Air models equipped with M1, M2, M3, or M4 Pro or Max chips. For base M-series MacBooks (without Pro/Max) and iPad Pro models with M1 or later chips, it supports a single external display. The dock is driverless for macOS.
Does the dock require external power or software drivers to function?
No, the dock is designed for true plug-and-play operation. It draws power directly from the host laptop's Thunderbolt 3 port, eliminating the need for an external power adapter. It also does not require any software or driver installation for core functionality on supported Windows, macOS, or Ubuntu systems, making deployment quick and straightforward.
What are the IT management features of the Gigabit Ethernet port?
The integrated Gigabit Ethernet controller includes several professional IT tools. It supports PXE (Preboot Execution Environment) boot for network-based operating system deployments and Wake-on-LAN (WoL) for remote power management. It also features Network MAC Address Pass-Through, which preserves the laptop's original MAC address on the network for consistent security policy enforcement.
What is the length of the attached Thunderbolt 3 cable, and why is it beneficial?
The dock has a permanently attached 28cm (approximately 11-inch) Thunderbolt 3 cable. This length is strategically chosen to provide enough reach for comfortable setup while preventing the dock from dangling and putting mechanical stress on the laptop's port. It is especially beneficial for laptops used on riser stands, docking stations, or 2-in-1 convertible devices.
What operating systems are supported by this docking station?
The dock supports a wide range of operating systems without requiring drivers. This includes Windows 11, 10, 8.1, 7, Windows Server 2008 R2, and Windows Server 2012. For macOS, it supports OS X 10.10 Yosemite through the latest macOS 13 Ventura. It is also compatible with Ubuntu Linux, making it suitable for diverse and mixed-OS enterprise or educational environments.
