The battle for multiple displays on an M1 MacBook Air, Chapter 1

Right now, I am caught between two worlds. Specifically, Mars and Jupiter. I’m stuck in the asteroid belt, send help!

Just kidding.

I use both a Windows 11 PC and an M1 MacBook Air. Both are very nice machines and perform well. I think Windows 11 has caught up in many ways to macOS in terms of appearance and UI, and even surpasses it in some ways (window management remains much better, as I’ve noted before).

I would be Windows-only save for one thing: my fiction writing is done in Ulysses, which is a Mac-only app. Now, it’s true that my fiction writing has been moribund (very, very moribund) for the last year or so and if I had no intent on changing this, I could just put aside the MacBook Air for the fabled time when I’d actually need to go back out into the world with a laptop again.

But I am intent on actually trying to revive my fiction writing and I’m too lazy to look for or switch to another writing app, so I’m keeping my Mac–for now, at least.

My previous setup was a single 27″ monitor and it worked well for both PC and Mac. Switching between the two was not instant, but it was pretty easy and only took a second or two. I added a second monitor, which has been glorious for my Windows 11 setup. However, for ?reasons? Apple deigned to make its initial Apple silicon offering, the System on Chip (Soc) known as the M1, only work with a single external display.

This means I can only use one of my two 27″ monitors with my MacBook Air and I am sad.

But wait!

You can use a DisplayLink adapter or dock to sneakily connect more displays via USB. It’s confirmed to work with all M1 Macs (it’s not needed for the newer M1 Pro and M! Max SoCs, since they support multiple external displays). I procured one of these devices, specifically a StarTech USB-A to HDMI DisplayLink adapter. I downloaded the latest DisplayLink drivers (also required), connected the adapter to a free USB-A port on my CalDigit 3 dock and…it didn’t work.

With both monitors connected, only one or the other would work, neither would work at the same time (the “permanent” monitor is working via USB-C to HDMI).

Thus I began troubleshooting.

It’s worth mentioning here that the reason I went with a DisplayLink adapter as a solution is because it would be the cheapest way to get a multi-monitor Mac setup going (about $100). The next cheapest option would be to trade-in or sell my Air and get an M1 Mac mini, which supports two external monitors because it really only supports the same number as the Air, but since it doesn’t come with a display, it can actually display to two external monitors. This option, no matter how I might finagle it, other than winning the lottery, would cost more than $100.

Troubleshooting involved a lot of the usual stuff. I won’t go into details. It was bad enough that I suffered through it. No one else should suffer through it by proxy.

In the end it’s still not working. I have one thing left to try–switch the “permanent” connection from HDMI to DisplayPort, but this would upset my PC configuration, which is working just dandy, so I am loathe to do it. I might, if I manage to reach the right balance of bored and desperate.

For now, my Mac work continues to be single monitor, with the second display dimly showing my forlorn reflection and nothing else.

I have considered getting one of those new MacBook Pros by selling my Air and using other monies I have from previous trade-ins, but there’s no getting around it costing a lot more than $100, and it would be serious overkill for writing. I rationalize it by saying I’m getting into game development now and video editing and it would be useful for those things. But my PC already works well for those. But it is now and shiny and solves a problem, and so I ponder, occasionally glancing up to that forlorn figure looking back at me.

tl;dr: DisplayLink is definitely a hack when it comes to M1 Macs. This isn’t the technology’s fault, really, it’s Apple’s strange and arbitrary regression on monitor support for their first batch of Apple SoCs. Still, it’s important to remember what you may be getting into before making the leap, as I did.

Also note: All PCs happily support multiple displays without any trickery!

I end with a repeat of this:
