MacBook Pro 13" M1 Dual Monitors using Dell D6000

Hi,


Right now I have two Dell 1080p monitors (2x Dell 24 Monitor - P2419H) and I am using as a dock station a Dell D6000 which uses DisplayLink driver, both monitors are connected using DisplayPort.


Can I attach my 2 monitors as separated displays with a MacBook Pro 13" with the new M1 chip?

DisplayLink technology creates a "fake" display buffer in RAM, sends the data out over a slower interface to a stunt box with DisplayLink custom chips that put that data back onto a "legacy" interface. It is not a true "accelerated" display, and it suffers from lagging.


It may be acceptable for a second display showing slow-to-change data such as computer program listings, stock quotes, or spreadsheets, but NOT for full motion Video, and mouse-tracking on that display can lag, and can make you feel queasy.

It is really nice to know that you can use a DisplayLink display if you MUST have an additional display for some of the types of data I mentioned. But that is NOT the same as the computer supporting a second, built-in, accelerated display.


These displays depend on DisplayLink software, and are at the whim of Apple when they make MacOS changes. There have been cases where MacOS changes completely Borked DisplayLink software, and it took some time for them to recover.

I think the Big Surprise for a lot of Hub/Dock buyers is that they thought they were getting a "real" display, but actually got a DisplayLink "fake" Display. If you got what you expected in every case, I would not use such strong terms to describe DisplayLink.

With the release of Big Sur 11.3 on April 20, 2021, Apple fixed all the issues with DP1.4 monitors.


So, at this point using DisplayLink docks for connecting to DP1.4 monitors to alleviate M1 issues with DP1.4 monitors is no longer required. One will still have to use a DisplayLink dock if more than one external monitor is required with an M1 MacBook Air/ MacBook Pro.
