He has an army of people that would read his emails. A truly important one should get read. You could always try calling, too! I cold called Marc Benioff at Salesforce and he actually picked up the phone.
This needs a story. What did you say to him?
He was told, he had a call from Pope

#73This is not a normal retina configuration. This is a highly unusual configuration where the framebuffer is much larger than the screen resolution and gets scaled down. Obviously it sucks if it used to work and now it doesn't but almost no one wants this which probably explains why Apple doesn't care.
I don’t know why this was downvoted, I agree that this is a highly unusual configuration. Why render to a frame buffer with 2x the pixels in each direction va the actual display, only to then just scale the whole thing down by 2x in each direction?
Because Apple no longer implements subpixel rendering for fonts?

#74Yep. Apple sells 5k displays, which work fine.
Just another case of Apple intentionally going against established open standards to price gouge their users.
I wouldn't mind it as much if I didn't have to hear said users constantly moaning in ecstasy about just how much better "Apple's way" is.
High quality desktop Linux has been made real by KDE, and the AI-fueled FOSS development boom is accelerating this eclipse of proprietary nonsense like this.
If you're a developer, you should be using a system that isn't maintained by a company that intentionally stabs developers in the back at every turn. (Unless you're into that. U do u.)

#75Props to the author for putting in what looks like ton of work trying to navigate this issue, shame they have to go to these lengths to even have their case considered.
I went to hell and back trying to get PIP/PBP monitors on my 57" g9 ultrawide to work with my M2 pro. ended up having to use a powered hdmi dongle, displaylink cable, and displayport, with 3 virtual monitors via betterdisplay. Allowing resolutions outside of macs limitations setting in BD is what did the trick. I don't envy OP. Having 5120x1440 @ lodpi was the worst, just ever so slightly too fuzzy but perfect UI siz…
You may be able to get this working using PBP and 2 cables without virtual displays. This is my write up for using HiDPI@120hz for two 57” G9s on my M2 MacBook. https://www.reddit.com/r/ultrawidemasterrace/s/VrBLFDxYzg

#76The ideal work/coding resolutions and sizes for macOS that I would suggest if you are going down this rabbit hole. 24 inch 1080p 24 inch 4k (2x scaling) 27 inch 1440p 27 inch 5k (2x scaling) 32 inch 6k (2x scaling) Other sizes are going to either look bizarre or you’ll have to deal with fractional scaling. Given that 4k is common in 27/32 inches and those are cheap displays these kinds of problems are expected. I hav…
I have dual 27" monitors, both at work and at home. At work, they're 4K monitors, because that's all they have in this size for some reason (LG if it makes a difference). At home, my own monitors are ASUS ProArt 1440p monitors. I run Linux in both places.
I really like my 1440p monitors at home more than the 4K monitors at work. At work, I'm always dealing with scaling and font size issues, but at home everything looks perfect. So I think you're onto something here: 1440p just seems to be a better resolution on a 27" panel.

Yup, 27" 4k with a Mac is truly awful. Don't do it. Get a 5k display.

#78What are they doing with MacOS? Is this due to VisionOS?

Yeah. I don't get it. If you've got a 3840x2160 display, intended use on macOS as a 1920x1080@2x display, what is the advantage of using a 7680x4320 buffer? Everything is drawn at twice the width and height - and then gets scaled down to half the width and height. Is there actually a good reason to do this? (I use my M4 Mac with 4K displays, and 5120x2880 (2560x1440@2x) buffers. That sort of thing does work, though i…

Is there actually a good reason to do this? Text rendering looks noticeably better rendered at 2x and scaled down. Apple's 1x font antialiasing is not ideal. Especially in Catalyst/SwiftUI apps that often don't bother to align drawing to round points, Apple's…
So, how do I actually set this for my Mac, or is this something which each application may or may not do?
