MacBook Pro external display

It used to be simple where each model has a “you get one display, you get two” but now with the 4k and 5k displays, one display can have more pixels than the 6 displays Mac Pro used to support.

Also, support is a vague term sometimes. Apple “supports” less displays than you can often connect since support means fast refresh, low likelihood of lags and slowdowns and glitches as opposed to “you’ll never get signal on this mess of adapters and cables and usb drivers and daisy chained devices”

That being said, here are the articles on multiple displays:

These Thunderbolt-3 capable Mac computers support multiple Thunderbolt displays:

• MacBook Pro (15-inch, 2016) and later supports up to four Thunderbolt displays using Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapters or daisy-chaining.
• MacBook Pro (13-inch, 2016, Four Thunderbolt 3 Ports) and later and MacBook Pro (13-inch, 2016, Two Thunderbolt 3 Ports) and later support up to two Thunderbolt displays using Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapters and daisy-chaining.

So you should expect two attached displays to run well unless there’s a 4/5k issue:

• https://support.apple.com/en-us/HT207447 (probably no issue with 2 4k)
