The custom display files does not work on an M1 mac mini. i tested this and it is ignored. i have the exact same monitor and a an m1 mini with the latest beta 6 of the upcoming release runningThere 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.
Got a tip for us?

Thank you very much for reporting back! Does it “only” not show up in the system preferences or not even with additional tools like RDM?
If not at all it is good to know that apple actually is falsely advertising the M1 Macs, as being 6K capable, while apparently they are not.
The Apple XDR Display is as much true 6K as UHD is 4K. This is especially sad, as all available 5K displays are true 5K, and Apple 4K displays (iMacs) feature true 4K resolution (unlike TVs).
- XDR: 6016x3384 (HiDPI 3008x1692)
- 6K: 6144x3456 (HiDPI 3072x1728)
- UHD: 3840x2160 (HiDPI 1920x1080)
- 4K: 4096x2304 (HiDPI 2048x1152)
It does give you an HiDPI resolution but its at 3008x1269 but not at 3360x1417 which is the ideal resolution for this monitor. 3360x1417 used to be available with the custom file on intel macs. 3008x1269 HiDPI isn't bad and would probably be great for 90% of the use cases but I use development tools and prefer the bigger space I used to get.
The problem with the custom files are that they used to work on the PCI bus and the new apple m1 display hardware configuration doesnt list it as apple internal under the pci bus any more.
there was a point where apple said they would fix the resolution issues on the m1 macs but i dont know if this would include custom resolution configurations like we could do in the past.
Override files have nothing to do with PCI bus.
Override files work on M1 Macs - but only to change the display name (maybe some other stuff we don't know about?)
I'll reserve judgement until a few days later. But so far so good here too, with DP 1.4 and HDR turned on.
So the DP 1.4 is fixed with no issues whatsoever but close lid mode does not work :-/ The monitor does not wake only the backlight goes on. I kinda got used to having a laptop open so not a big deal.
I wonder how it works for you. Did anyone manage to work with a closed lid on MacBook Pro 13" and LG 34WK95U?

Right, so did this fix the sleep/wake in closed lid setup? I saw several ppl claiming that they keep using their M1s closed since 11.4 without issues. My MBP does not wake up and the situation did not change since 11.0 (except the crashes and DP 1.4 support)
Just found this thread...Anyone got the issue fixed? It seems OP and I are facing a very similar issue though I am with a U2720Q instead of LG. Other than sleep-wake problem, HDR is also an issue for me...
My M1 MBA is connected to U2720Q with a single USB-C to USB-C cable (coming from the box). DisplayHDR is set and HDR is turned on in MacOS (problem exists with both Monterey & Big Sur). HDR content displays properly when the Macbook’s lid is open.
The issue starts to happen when I wake up the MacBook in clamshell mode by pressing any key on external keyboard/mouse. The U2720Q, after scanning signal, wakes up from energy-saving mode and displays in an apparently different colour visuals. The colours now look much more saturated, but HDR content and P3 colour are no longer visible. At this moment if I open MacBook’s lid, the U2720Q will go black for a second then resume normal. However, if I close the lid again (re-entering clamshell mode):

- with MacOS Monterey: the U2720Q will go back to the colour mode (or “profile”?) in which HDR content and P3 colours can’t be displayed properly
- with MacOS Big Sur: the U2720Q will stay normal. HDR content and P3 colours are properly displayed
TBH I don't get this HDR thing. When I enable it on my LG 34WK95U connected to MBP 13" M1 the colors get washed-out and even HDR YouTube moves look worst than without HDR enabled.
I was not able to get Macbook Pro 13 M1 (Monterey 12.1) working in clamshell mode with LG 34WK95U (DP 1.4) using a single thunderbolt cable until I did the following:
1. Install teamviewer on the macbook and on another computer or mobile phone.
2. Open display settings on the macbook
3. Open teamviewer on the macbook and connect the macbook to the monitor in clamshell mode
4. Press 'space' a single time to wake the computer
5. Immediately connect to the computer via teamviewer
6. Set resolution to scaled and then back to default for display

this monitor is a real pain in the ass and LG just dumped it right away after release with only coming up with one single firmware update fixing some issues. The sleep/wake issue exists for me from the very beginning after the initial release of the monitor. The so much advertised HDR didnt work for long time and after it started working, mac os looks just washed out as it is showing SDR colors in HDR mode. There is not a single alternative to this monitor (size -> resolution) It is so pitty that neither apple nor LG want to fix any of these annoying issues. Their support looks at these issues reported by nearly all customers of this model as this only happens for 0,00001% of the customers.
Sleep / wake and Bluetooth are the most common problems I have with so many MacBooks. Its crazy

Did you have any issues with resolution like people were having before? Were you able to get 5120 x 2160? Some people complained text was too small and icons too big in Final Cut Pro. Do you do any video editing or image content creation?
I'm between this (LG 34WK95U-W 34") and the LG UltraFine 27MD5KL-B 27" 16:9 5K IPS Monitor that Apple recommends for my upcoming 16" Macbook Pro M1 MAX
I'll appreciate very much your thoughts on this.
Thank you.
I've had this LG for several years now and have had an annoying issue when I go to wake it up, the Mac is waking up but the monitor is not. And to be clear I have 3 inputs connected. HDMI 1 from a 2014 Mac Mini. HDMI 2 from my work Surface Pro 7. Thunderbolt from 2018 MacBook Pro (which got replaced 2 weeks ago with a M1 Max Mac Studio).
What I have had for quite a while is that I have to press the button underneath 5-15 times to get the thing to finally wake up. The Mac is waiting but the screen is not coming on, not even the backlight. As of the last month or so, that behavior has changed and now no amount of pushing the power button works and I have to pull the power cord from the back and plug it back in and it comes up right away after turning back on.
So annoying. No resolution issues. The resolution is always correct. It just doesn't want to turn on.

Try this next time:
When you’re sure the machine is awake and the monitor is still asleep, press Cmd-Ctrl-Q. Then press Cmd-. That’s ”Cmd” + “.”.
That combination, put the computer to sleep with the keyboard, then waking it, has been awakening my LG monitor.
