edid.ksy VS BetterDisplay

An EDID override like this would be helpful for macOS as well, where the monitors swapping around after standby is a real annoyance [0] [1]

EDID rewrites are 99% of the time blocked by the monitor firmware: https://notes.alinpanaitiu.com/Decoding-monitor-EDID-on-macO...

By the way, one helpful tool that helped me navigate the EDID dump was Kaitai Struct [2]. It shows a side by side view with the hex view and the EDID structure, and it highlights the hex values in real time as you navigate the structure. Unfortunately [3] it doesn't support the extension blocks that the author needs.

> the 4K monitors the author recommends are not good for macOS due to them not supporting native retina scaling above 1080p

Is this true even with the help of 3rd party apps?

My 3840x1600 ultrawide has that problem using the native screen resolution tools but I can get it to full-res HiDPI using BetterDisplay [0].

2. "BetterDisplay" for better scaling quality on bigger screens, especially if you have a 4k ultrawide. https://github.com/waydabber/BetterDisplay

It isn't a device, it's a software tool. It doesn't make the monitor magically 2x the resolution; it can trick macos to render onto a 5k buffer and then downscale the output to the physical display so it looks not-broken.

I'm not saying that it'll make 4k look good. I'm saying macOS is unusable on native resolutions - everything is either too small or too blurry, so a 4k display won't do me any good. 25x14 is the sweet spot for me, but I guess Apple decided I'm holding it wrong.

Download BetterDisplay (free to try, $18 for Pro, and well worth it IMO): https://github.com/waydabber/BetterDisplay

This article is very good to explain this ppi thing https://bjango.com/articles/macexternaldisplays2/ also an extra app can make some monitors display sharper (hidpi) https://github.com/waydabber/BetterDisplay

It can be found here: https://github.com/waydabber/BetterDisplay

So I installed the Better Display 2 app [link] , enabled HiDPI 1280x720, and suddenly everything looked both extremely sharp and in a good size. Judging by the size of the screenshot, it mimics Retina 2560 × 1440 and scales it down 2x to 1280x720, making it HiDPI. I can totally recommend you to do as I did.
