The display output of the M1, according to the very clever devs working on Asahi Linux, is a bit funky under the hood.

I've found display compatibility has not been straightforward, having owned an M1 mini for the last year...which is unfortunate for a computer without a built-in screen.

Don't count on it supporting multiple external monitors. Expect compatibility issues, etc.

Last week it kind of burned a flickering rectangle onto my Dell ultrasharp 4k, which I thought was toast, but it gradually cleared up.

Like I said - weird.

Well, no way I'm buying a M1 due to the lack of RAM. Hopefully Apple will make a decent desktop for me next year and fix some silicon bugs while they're at it.

Incidentally, my current x86 mac mini is wonky with the hdmi output as well. The monitor randomly goes black for a few seconds once in a while.

ram is on the chip with the cpu now. so i don't see that changing in the near future with the laptop/mac mini versions of the M1 at least

The M1 Super Duper Max Pro supports 64 G ram if you haven't noticed. All they have to do is put it in a Mac Mini... I don't need a new laptop right now.

The black screen problem is usually a bad HDMI cable.

All my HDMI cables are bad? :)

The only kind I'm missing is the gold plated kind.

Apparently so, as Mac hardware never fails! ;)
