The LMP USB-C Triple Display Dock 4K is a fully functional USB-C docking station with 12 ports that supports up to three 4K@60 Hz monitors via HDMI 2.0. Thanks to the DisplayLink video chipset (DisplayLink driver must be installed), there are no limitations on the number of external monitors even for MacBook Air/Pro models with M1, M2, and M3 processors. Two of the three HDMI ports operate on the DisplayLink 6950 chipset and use the USB protocol to transmit the video signal, while the third HDMI port uses the traditional DP Alt mode signal and therefore does not require a driver.

The Triple Display Dock features a variety of additional ports, including Gigabit Ethernet, 4 USB-A (5G) ports, 2 USB-C (10G) ports, a 3.5mm audio input/output, and a Kensington Security Slot. The dock provides a pass-through power delivery (Power Delivery 3.0) of up to 85 W to the connected host computer, ensuring sufficient power for connected devices. A dedicated USB-C port allows for the use of an external USB-C Power Delivery (PD) power adapter to power the Triple Display Dock and the host. The Triple Display Dock can also operate without an external power adapter, but with limited functionality. LED status indicators show the operational status.
