Scale 1680x1050 on rMB without an app

[alfacentauro]

I have successfully managed to inject a 1920x1200 resolution into the Macbook Air M1 running Big Sur 11.3 Beta 3.

OS: macOS Big Sur 11.3 Beta (20E5196f)
Tool: SwitchResX Beta 4.11.1a4 (Build 2022)

Method:

1. Install SwitchResX Beta.
2. Open SwitchResX within System Preferences.
3. Navigate to About SwitchResX
4. Install Helper tools and Launch Daemon.
5. Select Internal Display on the left-hand menu.
6. Select Custom Resolutions
7. Click the + icon at the bottom left-hand side.
8. Ensure the options dropdown on the top left-hand side is Scaled resolution
9. Enter 3840 under Horizontal Resolution
10. Enter 2400 under Vertical Resolution.
11. Click OK
12. On the System menu for SwitchResX on the top left hand of the entire screen click Display.
13. Click Write System Settings
14. Reboot your machine.
15. Navigate back to SwitchResX upon reboot
16. Under the Current Resolutions tab, look for a new HiDPI resolution of 1920 x 1200. 60 Hz.
17. Activate by clicking the radio button to the left of the resolution.

Comments: Resolution works well and without issue. At present, I am unaware of how to accomplish this without an app, but SwitchResX is extremely light and effective.

Tried without success it shows 'Not active' and there is no way (I tried to reboot)

Very very disappointed with Apple.

Hello,

I checked today and noticed HiDPI options were available for my 1440p Display today, with 144Hz as well! My monitor is an Acer XF270HUA. This is potentially great news, as this is the reason many people use BetterDummy!

I’m not familiar with this app but can I scale
My 1920x1200 16:10 external monitor to a different DPI than 1920x1200? When I want it smaller in text and window size? Thx

the changes I applied I think on Big Sur on my M1 Air, carried to Monterey and now Ventura 13.0 RC fwiw.

possible to get "1920x1080" scaling on M1 Pro MBP14?

I would try a higher resolution on my 15" MBA with this method, but to be honest I think stock max size of 1920x1243 is good enough DPI wise

Even then I like a step down for my daily driver
