Description
Hi, I’m using BetterDisplay mainly for HiDPI.

I upgraded to a Dell U3425WE (3440 x 1440) and HiDPI is not working as expected:
•When I enable HiDPI, the monitor’s resolution drops automatically.
•If I use the slider to increase the resolution back to 3440 x 1440, HiDPI turns off by itself.

So I can’t keep HiDPI enabled while using the monitor’s native resolution.

Also, I’m running the monitor at 3440 x 1440 @ 120Hz

HiDPI works perfectly on my older 1080p LG monitor.

My setup
•BetterDisplay: 4.1.5
•Mac: MacBook Pro M4 Pro
•macOS: 26.2 (stable)
•Monitor: Dell U3425WE (3440 x 1440)
•Connection: [USB-C]
