2 years later switched from m1 to m2 and it no longer works well enough (may also be the Sonoma upgrade stil gotta verify that). The devices get disconnected and glitch etc.
Went to check with dell and monitor is "not supported" on macos.
I am at a loss for words.
I ended up going with the nuclear option of an IP KVM https://www.raritan.com/support/product/dominion-kx-iv-101 that will do all the resolutions I want at 60hz. It was very expensive, but on the bright side it lets me keep work laptops completely unmodified and easily swappable.
Disclaimer: meant to be humorous.
Apple also refuses to implement a protocol that allows controlling the brightness and volume of a non-Apple monitor from the keyboard or even macOS itself. It's infuriating. The only monitors it works with are Apple's and the two overpriced Apple-sanctioned LG monitors sold in the Apple Store.
From MonitorControl's GitHub README, emphasis mine:
> Most modern LCD displays from all major manufacturers supported implemented DDC/CI protocol via USB-C, DisplayPort, HDMI, DVI or VGA to allow for hardware backlight and volume control.
And a blog entry by the author of Lunar, an app mentioned elsewhere for this problem: https://alinpanaitiu.com/blog/journey-to-ddc-on-m1-macs/
These are not examples of "just works". Apple intentionally does these things to cripple integration into non-Apple products.
I'm just explaining how it doesn't just work, and that I'm perfectly happy not using their products. My comment was also a correction that it's on Apple, and not Dell, as to why Apple products don't work well with non-Apple devices. This is a tactic that Apple uses to try and denigrate non-Apple products and get people to come back to Apple's "premium" versions of those products.
There are clear and easy steps Apple could take, but they won't.
That's the one justification that consistently gets upvoted to the top any time someone questions Apple's pricing structure. Please don't change the tune when someone reports a serious ongoing problem.
