I like that they clearly admitted to it, so I know what I'm buying. Other products usually pretend to support anything and let me discover the issues after purchase (like an XPS 15 with a GPU that couldn't actually run games the GPU supported, because of insane thermal throttling).
I'm using it on one of the Pro XDR displays, and it's quite impressive for the cheapest notebook to drive this monster of a pixel-wielding behemoth with zero issues or complaints...
(2732*2048 + 2560*1600 + 6016*3384 = 30,000,000 pixels, although I'm not sure if the iPad receives a pixel signal, or renders its own content)
So it doesn't seem to be a lack of graphics power that causes this limitation.
(Incidentally, the XDR and current-gen iPad pro displays are the first where I get the illusion, when watching high-res video, that there's an actual window in the display and I am looking at a real scene behind it)
Anecdotal reports online seem to indicate displaylink on m1 is fine for everything except gaming including 4k60 video. M1 is not something you really want to do gaming on anyway, especially not with multiple monitors. I’ve done a video conference on my m1 air through a displaylink-connected monitor and I couldn’t tell the difference from having it on the built in screen. I guess it depends what people want to do, but I think for most people most of the time this is a perfectly suitable solution on m1 (not so much on older weaker intel cpu’s though).
