| Jan 12, 2022 at 3:52 | comment | added | MegaMatt | What? No Allan, sorry but you’re dead wrong on his MacBook only supporting one external display. The tech specs are clear: with a proper dock, he can run his laptop screen AND up to four external displays. The link to tech specs you provided is broken, so here’s a new link: support.apple.com/kb/SP776?locale=en_US. See the Video Support section. Now, there’s apparently a compatibility issue between Macs and the Lenovo docks, which Phillip Remaker details, so that’s likely the OP’s issue here. But this answer should not be upvoted because it’s wrong. | |

| Apr 17, 2021 at 15:45 | comment | added | Phillip Remaker | This is not a display bandwidth issue at all. The method that the Lenovo docks uses a technique not supported by MacOS, namely, DisplayPort MST. To prove that this is the case, load Windows 10 on to the Mac and the multiple extended monitors will work just fine. | |
| Jan 24, 2020 at 15:44 | comment | added | thst | I have a MBP 13" 2019 and I can use the dock with mouse keyboard and one external display, for the second ext. display I was forced to use a separate cable (HDMI over usb-c mobile hub) | |
| Jan 16, 2020 at 9:34 | comment | added | John Little | NOTE, the macbook pro 2017/18 DOES support 3 non-mirrored monitors - two external and the internal.. I have two external 2560x1600 displays connected via a single thunderbolt mini doc which has 2x DP out. However, if I use the thinkpad thunderbolt doc, it willy only mirror the two displays. This sucks. | |
| Mar 22, 2019 at 18:58 | comment | added | hxin | Then the purpose to use the dock is meaningless in regards of extend displays. It may still be useful to have more USB ports, but that's about it. Does "more than 1 external monitor" mean I can connect 3 external monitors directly to the type c ports? (another one for charger) | |

| Mar 22, 2019 at 15:36 | comment | added | hxin | Sorry, maybe I should specify that my MacBook is actually MacBook Pro (15-inch, 2018). Would that make any difference? It has 4 USB Type-C ports, one of them has to be for the charger. When I connect 2 monitors through the C port separately, they extended. So that way I have 3 different displays including the built in. | |
