In order to utilize a combination of devices, the number of displays allowed relies heavily on the systems GPU. If it is a Macbook Pro with only an Intel based GPU, the maximum number of displays allowed to be connected externally is 2. If it is one of the higher end AMD/Dual GPU systems, the maximum supported displays would be 4.
Once this information is obtained, the best combination of devices that will allow for 3 total displays (if the systems GPU supports 2 or more) would be the usage of our TBT3-UDV Thunderbolt 3 Docking station (https://plugable.com/products/tbt3-udv) which will allow two total displays to be connected to the dock (1 via the built in Dp 1.2 port, and the other connected via a USB-C/Thunderbolt 3 to HDMI/DP cable) and another to be connected to the other side of the Macbook pro, utilizing one of the available USB-C/Thunderbolt 3 ports with an additional USB-C to HDMI/DP cable. Examples of our supported USB-C/Thunderbolt 3 display cables are:
These individual cables due have specific resolution and refresh rate support, so if you have any questions regarding the displays you are hoping to connect, please let me know!
I hope this information helps, if there is any additional questions or concerns, I would be more than happy to assist!
Thank you for your patience,
