I just updated to 26.6.2, and that made me loose support for 3840 x 1620 and 120hz on my Dell U4025QW. It had been working just fine on my Mini M4 Pro up until now. >_<

What a mess.
It never fails to amaze me how bad Apple is with display support. A very cheap Windows laptop supports virtually every monitor…

165hz on 3840x1620 HiDPI feels horrible

Without hidpi it's fine but as soon as I enable hidpi it doesn't feel 165hz at all
 
Ooo, nice monitor! Tempted by that myself. Which Mac have you got and can you run it in the look like 1440p mode?
Yes it's great and I seemed to have gotten lucky. My panel has no visible issues. I have an M1 Max. I do not see 1440p in the list of resolutions in Better Display though. Not really sure how to go about looking into all that.

If you go into system settings > displays, do options show up like the below screenshot?

Yes sorry I have mine as a list (showing all resolutions) but it's not there. It goes from "2560 x 1080 (Default)" and then next up to 3008 x 1269.
Interesting.... It really does seem that Macs are just awful with ultrawides. Maybe i'll avoid buying one without at least having a Mac with native DisplayPort 2.1 support.
