Settings - Display: wrong resolution selected

[tuananh]

My monitor resolution is 5120x1440 and it shows that resolution (5120x1440) is selected. But it feels like it's 3840x1080.

when i tried to select 3840x1080, it automatically select 5120x1440 back.

I'm not sure how I can provide more information on this.

I install cosmic from 22.04. Not sure if that make any difference.

I would be very confused, if actually runs at a lower resolution, but lets see.

First could you run cosmic-randr and see, if that also reports 5120x1440?
If it does, could you run drm_info please (you might need to install that) from a terminal in cosmic and post the output?

cosmic-randr indeed reported that it's using the lower resolution

I change it with the command line and it works now

cosmic-randr mode DP-1 5120 1440

but in cosmic settings, it's now showing the lower resolution as selected.

I'm guessing its sth to do with the index when displaying?

summary:

• settings show 5120x1440 but it's indeed 3840x1080.
• changing with cosmic-randr to 5120x1440 and settings is now showing 3840x1080

I'm guessing its sth to do with the index when displaying?

Not unlikely, it might be thrown of by the order of the resolutions reported, with the one being reported first and preferred by the display, not being the one with the maximum size.

Definitely a cosmic-settings bug then, cc @mmstick

Is this still an issue?
