If your display has multiple inputs, prioritize them in the following order: DisplayPort/mini DisplayPort, HDMI, DVI, VGA. DisplayPort technology is the most compatible method of connecting to a display and Apple has been using it exclusively for several years. Even on the current-gen USB-C equipped MacBook’s, the technology used to transmit video is DisplayPort. Older technologies should not be used unless there is no other option and, because of their age, may have severe compatibility issues with newer computers.
5K Support: The Vertical Docking Station for the current-gen MacBook Pro will support one 5K display via the docking station. 5K displays are only compatible with the current-gen MacBook Pro (2016 and later).
4K Support: 4K displays are currently only supported on the MacBook Pro (late-2013) and later and the MacBook and MacBook Air (2015) and later. Before purchasing a Henge Docks docking station, please refer to the information here regarding how to connect your MacBook directly to a 4K display. Connecting via one of our docking stations would then be as simple as plugging your display into the dock in the same way you would connect it directly to your computer¹².
Vertical Docking Station for the current-gen MacBook Pro (2016 and later): You can connect your devices via the docking station in the same way you would connect them directly to your computer (if you were to only utilize the left side). In most cases this will mean using adapters or a hub, such as the Stone docking station, to give you access to enough ports³. The Vertical Docking Station will output to a maximum of two displays up to 4K or one 5K display.
Tethered Docking Station: The Stone Tethered Docking Station is compatible with the current-gen MacBook and MacBook Pro only. Legacy MacBook’s, even via adapters, will not work when connected to this docking station. Stone is a USB device and is not compatible with Thunderbolt displays or peripherals. Stone will output to a single external display via the mini DisplayPort on the rear of the docking station. Most modern displays come with the cables and adapters you would need to make this connection.
Vertical Docking Station for legacy MacBook and MacBook Pro: If you'd like to use a non-Apple display, you'll simply need mini DisplayPort adapters to connect to your monitor (HDMI, DVI, etc). if you wish to connect to a Thunderbolt monitor, you'll need to remove the cables that came preinstalled in the dock, as these are mini DisplayPort cables. It's a very simple process that's detailed in the User Guide.
Vertical Docking Station for the MacBook Air⁴: The MacBook Air is not capable of outputting to more than one external display natively but you should be able to add a second display by using a USB Graphics adapter⁵. You can pick those up from most online electronics retailers and they are relatively inexpensive. Make certain that the one you select indicates it is compatible with macOS. Henge Docks would not be able to recommend any particular brand or model of Graphics Adapter and we recommend contacting Apple directly for support around adding additional displays.
Horizontal Docks for the legacy MacBook Pro: There is one Thunderbolt 2 port, one mini DisplayPort, and one HDMI port. If you'd like to connect two Thunderbolt displays, you will need to connect one display to the Thunderbolt 2 port on the dock and daisy-chain the second display off of the first display. If you'd like to connect to non-Apple displays, you'll simply need mini DisplayPort adapters to connect to your monitor (HDMI, DVI, etc) or use the HDMI port.
Please note: The Vertical Docking Stations for MacBook's released prior to 2016, excluding the MacBook Air dock, are designed to fit Henge Docks and Apple-branded cables. We recommend purchasing one of these to ensure that they will fit in your dock. As the Horizontal Dock does not require cable installation within the dock, all cables should be compatible with the dock.
¹ USB-C displays are only compatible with a computer that has a USB-C port
² The Stone Tethered Docking Station is not compatible with USB-C displays
³ The Vertical Docking Station takes advantage of closed-display mode with has several requirements to work. Please refer to the Apple Support article here to make certain you have everything you need to work in this mode prior to purchasing a docking station
⁴ The docking station for the MacBook Air is not compatible with Thunderbolt displays or peripherals
⁵ As of macOS High Sierra, the MacBook Air will no longer support USB Graphics Adapters
