Like bug 2085890, this should probably be closed since it's an
unsupported driver (560) for Ubuntu 24.04. But if changing cables helps
then great.

I confirm the new DisplayPort cable resolved the 60Hz issue.
I am still testing Wayland to verify it resolves the issue when working on 3
monitors.

Yes fractional scaling is fine for Wayland. But problematic in Xorg.

Thank you Daniel.
I'm waiting for a new DisplayPort cable and let you know what happens.
Meanwhile I switched to Wayland the login. I was able to keep the
fractional scaling. I tried not to use it, but it's very hard for me to
use either 100% or 200%. They are definitely too extreme.

BTW the 30Hz problem is usually caused by a low quality HDMI cable (when
it happens to other people). The best solution is to use DisplayPort as
much as possible. But if you are forced to use HDMI then make sure the
cable is rated for at least HDMI 2.0 or 2.1.

Thanks. I can see you're using Xorg fractional scaling which can cause
multi-monitor problems. So please try selecting 'Ubuntu on Wayland' at
the login screen. If for some reason that's not available then please
try disabling fractional scaling in Settings > Displays.

I attached the xrandr output. Be advised the two monitors are using
different cables (HDMI and DisplayPort). I am going to buy a new
DisplayPort cable to further test this.

If the 30Hz issue persists even after swapping cables then it sounds
like a problem with one of the connectors or ports. Assuming the
monitors are absolutely identical. Because the product specs suggest a
4060 Ti can do at least 4x4K displays.

I did change three cables but I still see 60Hz on the second monitor and

The closest thing to a reset that GNOME has is:
1. rm ~/.config/monitors.xml
2. Log in again.

Great to hear that. Meanwhile, I would like to know what to do when this
happens.
There is no documentation about resetting the monitors status to default in
this case.
