Compatibility Issues to Consider
A safe bet for a successful MacBook Pro dual-monitor setup is to start by confirming your model’s ports and display specifications on Apple’s site, but here are a few general things to keep in mind.
Compatible Cables and Adapters
Not every MacBook Pro uses the same connections for managing external monitors. Whether you’re planning to use a Thunderbolt or Mini DisplayPort cable to set up an old iMac in Targeted Display Mode or you’re using a direct HDMI connection, you need to verify some things. Double-check your MacBook ports and make sure that your monitor of choice is compatible ports-wise—or that you have an Apple-compatible adapter and cables to facilitate the correct connection.
Number of Supported Displays
MacBook Pros with the new M1 chip support only one external display, but if your MacBook Pro has Thunderbolt 3 ports, each one should support an external display. Older models with Mini DisplayPort, Thunderbolt, or Thunderbolt 2 connections tend to provide the ability to connect up to two external monitors. When in doubt, check Apple’s site to confirm the number of supported displays for your model.
Supported Display Resolutions
Many newer MacBook Pro models (2019 and later) support ultra-high 4K resolution or even 5K or 6K monitors. If you plan on using one or perhaps multiple high-res external monitors, confirm your MacBook Pro’s graphics card supports your desired display configuration—both the resolution and the number of screens you want to include in your setup.
