Hi rojharris,
I am having the same issue with my LG 40WP95C. I have a 16" M4 Max MacBook Pro.
Resolution of 3840x1620 not supported.
My M1 Max MacBook Pro worked no issues with this resolution. Not sure what the issue could be.
Got a tip for us?

@Newgoblin49 I received the DP cable but no luck. Same behavior with thunderbolt. I'm convinced that it has something to do with DSC support of monitor. Anyways, created a case to Apple, shared screen recording and all details. They're going to forward it to engineering. I'll hear from them soon.

Thank you so much @maksakal !
Like I said earlier , seemed more like a monitor issue since there wasn't a single person on this thread with an LG who has gotten it to work.
With your analysis we're getting closer to solving this problem.
let me know what Apple says
Thank you
I have updated the main post with what we know so far for different 5K2K displays
Please take a look
Please take a look
Thanks for the list. LG 34BK95U -> Both TB and DP don't work
I've updated accordingly.
Also , maybe it's a better idea to speak to the LG engineers too. Ive done some digging on DSC and it turns out there are other factors like firmware updates that could come into play.
Makes sense. Let me reach out to LG Support too. Thanks for suggestion.
In a last ditch attempt to get it to work on the U4021QW I'm going to order an HDMI cable today and if that doesn't work then either the mac goes back to Apple or I have to get another display that I know will work.. :-(. Crazy that my 6 year old PC scales beautifully on this monitor...
Would you guys reccomment the U4025QW ? Is it definitely working on MAX with no work-arounds? I know it's in @Newgoblin49 's list but I don't want to install extra software if I can avoid it.

Hello ,
Like I’ve mentioned you’ve got a MAX , it has to work with the U4021QW.
An HDMI cable won’t solve it for sure , you’ll have to go with a TB4 cable or the USBC 8K to DP 1.4.
Upgrading to the U4025QW definitely seems worth it for the 120Hz refresh rate you’ll also get with it.
I don't need 120Hz as I've never had an issue with the 60 I get on the M1 with the current monitor. As you can see in the posts above, I'm not the only one with this issue. The MAX definitely does NOT work with this monitor so I assume it's too old and something needs changing.
Of course there could be an issue with the mac. Maybe it's a dud.... I'm going to call an Apple support person this morning and see what they think
Do you have display units for Dell monitors in your country. you can test the U4025QW with your Mac
I'm in the UK. That's not a bad idea. Not sure where would have a monitor like that though. On the other hand, I can order one and if it doesn't work I can send it back as we get two weeks to return anything bought online here. Cheers

Hello Guys,
@MxDaviD - maybe I missed the relevant post, but could not find any other users managing to get 3840px HiDPI working on a 5K2K display like you. 🥴 It would be useful to have all the info (see #194) so we could understand better what's happening - but only if you have the time for this of course. Thank you!
I can see that someone else got a U4025QW working with the base M4.I am happy I am not the only one
I have also been debating the Apple Studio Display before this Dell and I have to say that for me, this is the better display....

Samsung G95NC. It's the equivalent of two 32" 4K displays. I wouldn't necessarily recommend it for Mac users because it has a whole bunch of problems on MacOS that don't exist on Windows. The biggest being max 3840x1080 HiDPI scaling on one input. It has to be run as two displays to get proper scaling levels. I run mine as a 21:9 + 11:9 so it pertains to this thread. That 3840x1620 scaling is pretty essential for a 5120x2160 screen being nice to use.
I find that MacOS often has issues detecting the 21:9 side connected to the HDMI port. It sometimes gets detected as 3440x1440 and I have to use BetterDisplay to reinitialize the displays. @waydabber 's work is highly appreciated as his tool really helps. I might've returned the display if it wasn't for his app.

It's just two 32" 4K panels side by side but without any bezels and with curvature. Plenty of people use multimonitor setups that are similar and take more desk space.
So... I seem to have got 3840 x 1620 working using Better Display to make a Virtual Display and streaming it to the Dell display. This didn't work yesterday but that was because I didn't set it as 'Main Display' in system settings. I'm going to see how it goes today but tentatively I'm happy! All credit goes to @waydabber of course! I followed the instructions here:

I see. But that post was not about the mini. The situation there is different because on a MacBook Pro one of the displays (the built-in display) is always known by the system so the algorithm that allocates resources obviously should work differently.
I had the impression that for @MxDaviD the 3840px HiDPI on a 5K2K ultrawide was available on the entry level M4 mini. If this is not the case, then the situation is clearer as there is no outlier then.
Right, with virtual screen mirroring you can go even beyond even 3840px HiDPI limit (just turn on 'Enable resolutions over 8K...' under Settings/Displays/Overview/Additional settings...). However this is more of a workaround instead of a full-fledged solution to the problem.So...
