If the M2 Air supported two displays, I’d have no reason whatsoever to buy the expensive MacBook Pro. The M1/M2 Air is already so ridiculously overpowered for my needs. Which is probably why the Air doesn’t support two displays. Sigh.

If you're not fussed about a bit of extra CPU usage and you are not playing games on it, you can use a DisplayLink-capable hub to run two 4k screens @ 60Hz. E.g. https://www.sonnettech.com/product/m1-mac-dual-displayport-a...

I recall reading at least with the M1 that it's actually a physical hardware limitation with the architecture inherited from the fact that the base M1 is pretty close to the A15 which never needed to pump out to more displays.

The irony being that they then made the M1 Pro and M1 Max/Ultra that support more displays. In fact, I would be okay with it running dual displays like the mac mini where the internal display is disabled when two externals are connected. The M2, made after the M1 Pro still does not support multiple displays. It's an odd omission.

The M1 Pro is the same architecture.

Genuinely curious: can I hook up the Air with a single ultra-wide monitor that's exactly as large as two regular monitors side by side, or is the screen resolution limited, too? I'm thinking of something like [1], though it will probably make more sense to get a MacBook Pro instead at that kind of price.

The MacBook Air supports up to 6K resolution displays, your linked display has 60% fewer pixels than that, it will work fine

It should be fine. I'm typing this on an M1 MBP hooked to a Samsung CRG9.
