Is it a big secret that m1 macs don’t work with external monitors?? The problem has been getting worse with each new forced update.

Using my monitor via HDMI and apples 100$ dongle it constantly turns off randomly and will not come back on without unplug and plug back in.

Everything else is great but after like 5 updates that claim to fix the issue but still having issues maybe apple should make some notification about the problem so people don’t buy this if they have serious work they need to get done.

My M1 works flawlessly with my usb c LG monitors except for HDR leading to washed out colours.

On the other hand, both my fullspec 2016 and 2019 MBP have days where the displays and usb and Bluetooth hubs freeze every few minutes and I’m watching a the screens go blank and the windows being retiled while I can’t type. The only thing that continues is audio over the 3.5mm port.

So for me, things improved with M1.

Do you mind sharing the exact model number of your LG monitor? And is text as sharp as the Retina display?

Sure: LG 27UL850-W. I can’t say whether it is exactly as sharp but to me it looks similarly sharp. Both scaled and on native resolution. The colours of the M1 screen are better however.

I’m using the exact same screen and it is what led me to write Lunar actually.

The screen is great, text is perfectly sharp in 4k on both M1 and Intel Macs. I don’t have the HDR function because I bought it 4-5 years ago but the colours look very good too, no washing out problem.

But the damn joystick man, I just couldn’t get past it and had to spend 4 years writing an app to work around it.

Are you sure that you have the UL and not the UK? The UL is HDR400 so actually not really hdr. The only thing is that macOS doesn’t seem to realise this and with all the toggling there are four states that occur:

MacOS and monitor no HDR: “correct” colours and brightness MacOS HDR and monitor HDR: washed out colours / very low contrast macOS HDR and monitor No HDR: very strange picture macOS no hdr and monitor hdr: also washed out image
