Big Sur supports 32:9 now. I'm finally running 5120x1440 on my Dell 49", which never worked at its native resolution in Mojave or Catalina, on my 2018 Mac mini via USB-C connection.Will they also fix it with intel macs? my 2018 MBP promised to support my 32:9 display and Apple still hasn’t baked in native support.
I have it too. What upsets me however is I had to buy a special $50 cable to do what I can do with Windows with an $8 cable.Big Sur supports 32:9 now.

The same reason people don't want a car windshield with a big black divider going down the center of it. The exact... same... reason..Is there any reason apart from aesthetics to have one of these monitors and not just place two ordinary monitors side by side?
I can see one wide monitor would be perfect for any timeline-related work. My work tends to be vertically oriented (text), so I'm more of a one monitor for work and the other for palettes/other stuff person. But for audio/video an ultra wide would be great. Spreadsheet people also seem to like them, but I think a 4k would be more handy (big sheets tend to be big in both dimensions).Is there any reason apart from aesthetics to have one of these monitors and not just place two ordinary monitors side by side?
I game on mine. (Using my Windows PC on input one) And FPS games put the cross-hairs at the center which means it gets split where the monitors come together. Also, it's nice to be able to have choice when resizing windows. I often have one window a t 2/3 and the other at 1/3. Two monitors pretty much keeps things at 50/50. I do a lot of my actual business work on my MacBook Air and occasionally plug it into the monitor thru input two when I'm doing spreadsheets and the like. So it will be nice to have it support it natively without any hassle.Is there any reason apart from aesthetics to have one of these monitors and not just place two ordinary monitors side by side?
I finally got it working... although I have been other threads with M1 getting update soon, on this monitor you need to change the on the Monitor->Quick press the main button (bottom right) to bring mani menu-> Toggle Up-> Select "Menu"-> Select "System" -> Select "DisplayPort Ver." and change it to "1.2" - its usually on 1.4 (1.1 only goes to 4k).. hopefully with the update (next Mac OS update maybe 11.11? 11.2?) the newer 1.4 version will be supported, this is just a software / driver issue. See screenshot attached with M1 Mac using 5K. Note: I switched back and forward between my Intel Mac and my new M1 to get the setting changed over but once set, it stays
In a new support document, Apple has acknowledged that when an ultrawide or super-ultrawide external display is connected to a Mac with the M1 chip, some resolutions supported by the display may not be available currently.

Apple says it is aware of this issue and has a solution planned for a future macOS update. Apple did not specify exactly when a fix will be available, but the first beta of macOS 11.2 was seeded last week, so that is one possibility.
To see additional resolutions for your external display, click on the Apple logo in the top-left corner of your Mac, open System Preferences, click Displays, and press and hold the Option key while you click "Scaled."
There is a running thread about this issue in the MacRumors forums.

1. and 2. along comments like the one quoted below do make a compelling argument.1. Takes up less space.
2. More immersive content consumption.
3. Not all macs support multiple displays without using laggy usb alternatives.
I have been pondering what would be one of the benefits and your comment and similar others have actually opened my eyes on this front. For video editing and stuff would be amazing too.I replaced two 27" monitors with one ultrawide so that I could have content centered in front of me instead of two monitor bezels.
Teenagers don't use multiple displays. BTW, if anyone has been paying attention the last few years, teenagers (and maybe early 20 somethings) are Apple's target demographics. You know those that wet their pants over new emojis.Macs are absolute garbage when it comes to external displays for me. Even with my new Mac Pro with a maxed out GPU, when I have 3x 4K displays, it will randomly drop 1 or more of the displays to 30hz every now and then and even a reboot often won't fix it. This has been happening for years and it still hasn't been fixed on Big Sur...WTF apple? This is something that both Windows and even many Linux distros manage to get right without a problem....
While Apple is working on this, maybe they can also pull their heads out of their rectums and finally add proper support for DisplayPort MST daisy chaining in MacOS. We know that this is a MacOS issue because the same Mac when booted natively in Windows runs MST with no problem. What is Apple’s reason for continually refusing to support MST in MacOS? Is it a petty attempt to “convince” people to buy Thunderbolt monitors?I am pleased that Apple is fully aware, next step fully resolving the problem.

Windows is still a **** fest with monitors. Win 10 got better but it's no where near Mac OS. Most of the cool Windows Multi-Monitor setup requires paid setup for basic features. Glad that Win 10 added the ability to put a start bar on both. It still gets confused at times.Just wish OSX supported proper scaling line how Windows does. I have x2 27” and a 32” and Windows looks much better than OSX
I suspect others with the DTK noticed and reported monitor issues as well (not just the refresh rate issue you reported, but the resolution issue mentioned by the OP). Plus Apple, with their own extensive testing, must have known about these.Raised this issue with the DTK for ultra wide screens a long while ago, granted mine is only 3840x1080 49" but can run at 144Hz Stuck in 60Hz on the M1 MBP.
Also, one monitor is better than two, ergonomic wise.[Fixed]
M1 [laptops] don't support dual [external] monitors.
HiI have it too. What upsets me however is I had to buy a special $50 cable to do what I can do with Windows with an $8 cable.
There should be no reason why it isn't supported now.I wonder if, with the next gen of AS Macs, we'll finally see support for Dell's 8k monitor.

8k (or '8k4k') display support in macOS?
Is anybody here with a powerful GPU — either a new Mac Pro / MacPro7,1, or a MacBook with an external eGPU — actually successfully using an 8k display, day-to-day? I got an amazing deal on a Dell UP3218K, Dell's 8k display. You're supposed to use two DisplayPort 1.4 cables to a single GPU to...forums.macrumors.com
You can have one ultra wide window, which is probably useful for some extreme spreadsheet users.Is there any reason apart from aesthetics to have one of these monitors and not just place two ordinary monitors side by side?
Really? What cable? I just used the USB-C cable that came with the Dell monitor. Not all USB-C cables are alike. Some only charge, some only carry usb data, some do video via displayport protocol, and some do thunderbolt.I have it too. What upsets me however is I had to buy a special $50 cable to do what I can do with Windows with an $8 cable.
Uses less desk space. Less cord, powerbrick management.Is there any reason apart from aesthetics to have one of these monitors and not just place two ordinary monitors side by side?
I meant fully support, i.e. 8k@60Hz, which is the native refresh rate of the display.There should be no reason why it isn't supported now.
A single DP1.4 cable is able to drive that monitor at 7680x4320@30Hz. I do that on my Mac Pro but I had to delete the override file (DisplayProductID-4147) found under /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-10ac to enable it.
The problem is you can't do that in Big Sur because system files are read only.
So my Mac mini (M1) is stuck at 4K and it cannot scale above that. It will max give me 3840x4320@60Hz (over a single USB-C / Thunderbolt 3 cable).
i have a 49" dell 4919 monitor and a new M1 Mini on order. looking forward to seeing the 5120x1440@60 in action. I'm using switches on my 2013 trashcan mac pro on it now. How is your Mini connected to your LG, TB3/USBC? HDMI? or some adapter? ThxInteresting, I’m running my 49” LG Ultrawide at 5120x1440@60 on my M1 Mac Mini without any issue.
