It's possible to increase the brightness in software on M1, by faking HDR (desktop capture -> scale brightness to HDR -> display).

One example: https://www.brightintosh.de/ but there's many others.

you just made my day I am so happy with this I could kiss you!* just saved me a bunch of coin cuz I was considering trading up for a m4 or otherwise to get better brightness

amazing!

* more a turn of phrase, a hug, a handshake, a thank you thank you thank you all suffice ;-)

		purchased as well. thanks! was looking for a way to tweak my connected monitors, too. this brings up a good Q -- what monitors other than the absurd Apple XDR are out there that are good at high brightness. I'm loving the brightness above 500 nits on this main screen I want it everywhere.
