Question Dell monitor stuck on 30Hz ?

[xotix]

Hello,

I have a Dell S2722QC monitor connected to a MacBook M1 from 2021.

Now I have a problem choosing 60Hz. I wouldn't mind 30Hz too much but the issue is that you can feel it in the mouse. No idea why but I guess it's some kind of sync issue?

What I figured out was that I can choose "High Resolution" for USB-C Prioritization in the monitors menu. The problem no is: The resolution is terrible. It just loks very bad. Funnily enough, if I choose "High Data Speed" the resolution looks way better.

I am quite sure it used to work just fine with "High Data Speed" and 60 Hz. I don't choose a high resolution.

I have a side question: If a monitor is 4k and you set it to 1920 x 1080 and you watch a movie on Netflix and set it to 4k - does it display in 1920 x 1080 then?

In any case, I'm fine having 1920 x 1080 - Just give me 60 Hz! 😀

Any input how to solve this is high appreciated!

Edit: Oh and I use the USB-C cable that came with the monitor.

You may have to set the usb c in the mac

As for the other question pretty sure netflix will either brute force a 4k image e.g it may force it to display 4k.

Thanks - well I randomyl fixed it at home but I have the same screen at work by chance but I have to connect via HDMI adapter. I get 60hz if I choose a low res (like a high res saying low res i.e. pixelated high res lol) but not otherwise. Cable and adapter should support 60Hz, looked it up several times.

Don't really know what else to do. 🙁
