External Display - Sonoma - HiDPI - Macbook air 15 M2

Hi everyone.

I have a MacBook Air 15 M2 connected to a Huawei MateView GT 34 monitor (resolution 3440x1440 - 165hz - 109ppi - 21:9 format - WQHD.

The default resolution proposed by macbook is 3440x1440 at 165hz, I connected the macbook with a USB type C cable Thunderbolt 3|4 to DP 1.4 with 34GB band (UGREEN USB C to DisplayPort 1.4 cable 8K 60Hz 30Hz 4K 240Hz 144Hz HDR VRR Thunderbolt 4 3).

If I keep the default resolution of 3440x1440 everything is very small and in any case not very well defined (reading emails is complicated).

If I try to set the proposed HiDPI resolution of 1720x720 (max high HiDPI resolution proposed in the complete list) everything is extremely large and in any case not very in focus.

I also tested all the other resolutions but each is worse than the other.

I would like something in between HiDPI resolution....

Now I can't understand why the system doesn't offer me further higher HiDPI resolutions.

I also tried using BetterDisplay but the result doesn't change.

Do you think the problem is caused by the cable o the monitor?

I have read more topics on reddit and more many people recommend using monitors that have a PPI of 110 or 220 to have optimal resolution (but in this case even though the monitor has 109 ppi it is still a disaster)

MacBook Air 15″, macOS 14.1

Hi everyone, if it can be useful to you, I managed to scale the resolution in HiDPI by setting the monitor to 2580x1080 at 165hz.

The result is excellent, now I can use the monitor.

All thanks to the guide below!!!!

I hope it can be useful :)

You're probably not being offered many HiDPI / Retina choices because your monitor isn't a HiDPI monitor.

3440x1440 pixels on a monitor with a 34" diagonal works out to about 110 PPI. That's about the same PPI as on a regular 27" 2560x1440 pixel monitor that you normally would run at native resolution (no Retina scaling). The text would be smaller than on a 24" 1920x1080 screen, but that would be something to be expected.

A 27" 5K display would have 5120x2880 pixels and about 218 PPI.

A 27" 4K display would have 3840x2160 pixels and about 163 PPI.

So if we ran your monitor at native resolution, and the other two in Retina "UI looks like 2560x1440" mode, the text on all of them would be about the same size. But the 4K monitor would have about 2.2x as many pixels (as yours) for drawing each letter, and the 5K monitor would have about 4x as many pixels (as yours) for drawing each letter.
