If you have a 5K2K monitor, as I do, then you are unable to enjoy decent 1.25 scaling. Everything looks pixelated because Apple don’t allow a ‘proper’ HiDPI mode with M1s.

The same monitor is absolutely fine on a 2019 Macbook Pro.

If you use BetterDummy, it creates a ‘fake’ display to mirror to. The result is beautifully clear display on the 5K2K.

This is the crux of the issue. M1 macs can absolutely do nice 1.25 scaling on a 5120*2160 display to give crisp text in the 140dpi range but they disable it.

That is the issue IMHO.

Plug any random monitor into one of those 2019 MBP 16" models, and there's a good chance it'll spin up its fans to the max in an attempt to escape, and failing that, passively resist further abuse by overheating and throttling itself to a standstill.

This might just be them overtightening in response to that problem of old (whilst continuing to deny its existence, of course heh).

Edit: Plugging in an external monitor (not all of them, seems random) will cause the laptop's GPU to instantly 4x its powerdraw to about 20 watts, which then lasts for the duration of that connection.

Didn't that get fixed in 12.3?

Sadly not on mine or several colleagues' machines. Even did a full wipe back when I read that. Luck of the draw I guess.

> 5K2K monitor

I.e, a monitor with a resolution of 5120x2160.
