Well at least the Dell seems fine in Tahoe. Keep in mind that 6k monitors are 16:9 and not 21:9.
Got a tip for us?

Do you have both monitors connected? Does anything change if you remove the Dell?I tested with the Dell U3224kba and assumed that it also applied to the Kuycon G32P because they use the same panel but unfortunately that doesn't seem the case. It seems that Apple has whitelisted the Dell only.
I'm also curious if you could do an EDID override to make MacOS think the Kyucon is a Dell...just to see if Apple indeed applies monitor model specific fixes.
It's a shame this grade A ******** continues with Tahoe.
Two different locations so I'm not able to connect both of them at the same time. I've just exported the EDID using BetterDisplay and will try to import it on the Kuycon tonight.
The problem also still persists for me with Tahoe and my LG 40WP95CP-W.
Until now, I solve it using a virtual screen with Betterdisplay to get the ideal 3840x1620 resolution.
If that works, maybe it could also work if I do an EDID override to make macOS think that my LG is a Dell U4025QW?

It works! So this confirms that Apple puts limits based on the display identifier. Thanks so much for the suggestion!
I'm no expert but the U4025QW does have a different refresh rate (120hz vs 72hz). But maybe you can lower the refresh rate?
The Kuycon and the Dell use the exact same panel with the same resolution and refresh rate (6144x3456@60hz).
"You're a Dell Harry!"
Awesome work @escargot2398. This is likely a better solution than using BetterDisplay to do a virtual screen.

I don't know how to do it, but I would like to try it, because I've read here that the Dell U4025QW has not the problem and although the refresh rate is different, the screen size is the same.
I have never used this tool, but I understand that with Betterdisplay the original EDID of my LG could be restored if something does not work, right?
In any case, I can do the test with a clean installation of the system that I have on another hard drive, not on the main start disk.
Anyone knows how we can get the EDID of the Dell U4025QW to try to ovewith our LG? Maybe someone could export it with Betterdisplay and share it with others to see if it works?
It doesn't actually overwrite your existing EDID in your screen but rather 'fool' MacOS with a different EDID. After disconnecting and connecting it actually reverts back to the original EDID. There's an option to automatically apply the new EDID with each time you connect the screen.
The first step is to get someone with an U4025QW to export their EDID. You could even adjust it to lower the refreshrate but I have no experience with it.
Thank you!
I have been doing some tests, I got the EDID of Dell in that thread and when importing it in Betterdisplay, macOS effectively recognizes it as another monitor and shows the desired resolution. But half of the screen looks bad, with some glitches. Interestingly, it seems that the other half reproduces the image without problems.
I am doing some tests, modifying the Dell EDID values with AW EDID Editor for Mac, trying to stabilize the image on the screen, but it seems that for now I do not find the right option.
I do not know if another possibility could be to edit the original EDID of the LG to let macOS to show the ideal resolution of 3840 x 1620 that by default does not show in computers with M4 processors.
If someone with more knowledge and a monitor like the LG Ultrawide 40WP95CP-W want to try... it would be of great help.
I am still amazed that my old 2017 Intel iMac can provide this resolution and not the newest 2025 Mac Studio.

Can you export the EDID for your LG and copy most of it to the Dell EDID using AW EDID Editor?
Or edit your LG EDID and replace the Vendor and Product ID?
If the rumored release of the M5 non-Pro non-Max 14" MacBook Pro happens this week, I hope that someone with an Ultrawide display mentioned in this megathread will buy one and report back to us whether it fixes the M4 problem or not
That's very interesting!
I thought they might do something like this because if my Samsung 57" 7680x2160 superultrawide in Picture by Picture mode is split as 2x 4K displays, it seems to work more reliably than if it's split as 5120x2160 + 2560x2160.
The 5120x2160 side sometimes gets detected as 3440x1440 and I have to use the "re-initialize external displays" feature from BetterDisplay. Otherwise I have no scaling issues with it, I get 3840x1620 on my M2 Max MBP 16" over the native HDMI port.
MacOS seems to struggle to figure out what to do with the oddball 2560x2160 resolution as well. I have to use BetterDisplay to force it to HiDPI for example, even though there is no technical limitation to it just working. If I run this over HDMI, it only works at 60 Hz, but over USB-C -> DisplayPort adapter it works at 120 Hz.
I hate to think what kind of spaghetti code Apple is running for their display detection if they feel they have to do these sort of fixes instead of providing a one size fits all solution based purely on EDID supported resolutions data. Windows doesn't seem to run into issues like these.
Perhaps just plugging the demo unit to a Studio Display in an Apple Store is enough to tell something, see if 3360px scaling option is there.If the rumored release of the M5 non-Pro non-Max 14" MacBook Pro happens this week, I hope that someone with an Ultrawide display mentioned in this megathread will buy one and report back to us whether it fixes the M4 problem or not
True but the litmus test will be someone with a 5K2K (like e.g. my LG 34”) who can see if the default/preferred 3840x1620 HiDPI resolution shows up or not.
