I had kernel panic again this morning with DisplayPort 1.4. I guess I'm switching back to using DP1.2... and so, no HDRThe Mac mini went into kernel panic this morning when I tried to wake up the monitor. The Mac rebooted and now it seems to be working fine under dp 1.4
Did you try switching from DP 1.4 to 1.2?I have the issue whereby the M1 MacBook Air kernel panics when restoring my LG 4k monitor.
Still occurs in 11.2.1 - it's reported to Apple as FB8925129
I did indeed. And the issue may be less frequent as a result. However it has happened at least twice since I downgraded DP. Have sent the crash logs to Apple.Did you try switching from DP 1.4 to 1.2?
I tried a thunderbolt LG 32 it was a mess with my M1 so back to the USB-C 4k 27 and its rock solid. hopefully apple will fix this soon.I did indeed. And the issue may be less frequent as a result. However it has happened at least twice since I downgraded DP. Have sent the crash logs to Apple.
After installing Beta 2 I still have an issue. Will try Beta 3 today.
Been following this thread; I use scaled resolution just so I can get more to fit into my 27" LG monitor. Problem is that after the computer wakes from sleep it wakes with everything zoomed in for some reason. Even the log in screen is zoomed. My log in profile is usually on the bottom right of the screen 🤷🏾♂. Kind of like I'm using accessibility zoom or something...
I'm using USB-C that came with the LG monitor since it powers the M1 Mac as well.
Hoping for a fix soon.
Where can I find this Firmware? My LG monitor model is BN88U-B and I can't seem to find a Firmware update anywhere.
Yeah I know it's not. But your post helped a bit.... Didn't know about this software. It works with my monitor. Just has no Firmware update.That's not even the monitor in the thread title. LOL.
For 34WK95U/34BK95U, it's updated through the "OnScreen Control" software. You download it from the LG web site.

I don't want to take risk in trying this even if it works. But FYI, on my m1 Mac mini, /Library/Displays does not exist.On my Intel Mac I use a resolution of 3072*1296 for the LG 34WK95U, as it scales better to the physical pixels (5120/5*3=3072), so that within every 3 physical pixels 5 pixels are rendered. An even better physical scaling is archived with a scaled resolution of 3820*1620, as it renders 4 scaled pixels to 3 physical ones, though this is too small for my taste.
As this resolution is not available on M1 anyhow, I wondered wether my custom 3072*1296 HiDPI resolution still could be applied on the M1 Macs, as it is only slightly larger than the current maximum of 3008*1269, and actually resembles true 6K (1024*6=6144 - HiDPI for 3072), which the M1s, according to apple, are capable off. If someone could try my custom override and report back, I would be glad as it would ease my thought on wether to buy an M1 Mac.
Unzip the attached file and move it to:Create the path, if it does not exist (might require admin permissions). After a reboot the resolution should be available as a scaled resolution in the system's display preferences.Code:/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-9e6d/
There is no risk involved. This is legit, apple supported behaviour for applying custom resolutions. - In case it does not work, you’d just have to delete the file and folders created, and if it does work feel free to use it or revert if you like.I don't want to take risk in trying this even if it works.
