For example, a MacBook Pro 15” model can have our TBT3-UDV dock connected to one Thunderbolt 3 port and drive two displays. One of our Thunderbolt 3 Dual Display Adapters can be connected to one of the Thunderbolt 3 ports on the opposite side of the laptop to add two additional displays bringing the grand total to four. This configuration still leaves two available Thunderbolt 3 ports in the system.
** An important note, our Thunderbolt 3 Dual Display Adapters must be connected to a Thunderbolt 3 port on the opposite side of the system compared to where the dock is connected. This is because the laptop has two Thunderbolt 3 controllers (one for each side) and they can each power two displays.
Our Thunderbolt 3 Dual Display Adapters and USB-C video cables can also be used individually on their own (without a docking station) to allow for additional displays to be added, within the confines mentioned earlier.
** Another important note, the maximum number of displays supported by either model laptop are finite when used with our products. The maximum number cannot be expanded regardless of what Plugable products are in use or how they are physically connected.
If a Thunderbolt solution proves too expensive for your needs, any of the USB-C docking stations we mention in the next section can also be used. This is because all Thunderbolt 3 ports can also function as a USB-C port.
Apple USB-C Only Laptops
With Apple laptops that have only USB-C support built-in such as the 2015, 2016 and 2017 MacBook models (notice the absence of the ‘Pro’ designation and hence the lack of Thunderbolt 3 support) the options are more limited. A MacBook with only a USB-C port is limited to a maximum of one external display.
Given those limitations, our UD-CAM dock (https://plugable.com/products/ud-cam) is a good solution to add one additional HDMI display, charge the laptop with up to 85W of power as well as provide additional USB ports, a wired gigabit Ethernet and a combination audio input/output jack.
