Display monitor stuck at lower resolutions

English Hardware
1

Hi All,
I have an IdeaPad laptop (i5) with Tumbleweed and I have just bought an external display (MSI PRO MP341CQ)
For whatever reason, the max available resolution of the display is 1920x1080, against hw specs of 3440 x 1440.

This is the output of inxi -Gxx:

Hi - here it is:

Are you using HDMI cable or using DPi cable?

I have a high-end (hardware-wise) desktop which displays to a 38" Dell curved monitor and my Linux system will ONLY display native resolution (the monitor’s native high end) using DPi cable … HDMI cable always restricts to 1920.

Same with my Dell laptop.

Hi, indeed I am using an HDMI cable.
Do you mean DPi would work better?

6

I can’t speak for your setup … but my Dell monitor included many cables … and when I swapped the HDMI cable for the DP cable (out of desperation), it INSTANTLY jumped to 3840x1600 resolution. :+1:

That would be quite awkard as my HDMI cable is actually explicitely tagged as “8K-UHD” suitable on the connector…

HDMI was originally designed for television. DisplayPort was originally designed for computers. Whenever there is a problem with HDMI and a computer, and DP is available, odds are good switching from HDMI cable to DP cable is where a solution lies. Another possibility with some computers is using a USB-C cable on the computer end, with a DisplayPort connector on the display end. Yet another possibility is connecting a dock via USB-C, and connecting display to dock. Docks depend on MST technology, which is a feature of DisplayPort electronics utilized by many USB-C ports.

One thing left me puzzled though.
I have disconnected my laptop and connected my work laptop, which has Win11 as OS.
Same display, same HDMI cable… but it goes into 3440x1440 mode smoothlessly.

So I would come to think it is something with Opensuse.

10

I wonder if a custom Modeline may be in order here. I see some information about it here :< xrandr - ArchWiki

What is the output of xrandr?

With the monitor in question connected, run kscreen-doctor -o in a terminal and report back with the output.

Perhaps. :thinking: it happened here when I replace with DP I was able to get 3840x2160.

15

Sorry, found out the issue by double-checking the technical specs of my laptop (Lenovo Ideapad Slim 5): the HDMI port natively support only up to 1920x1080@60Hz.
Gotta use the USB-C port who instead reach and go beyond my display max resolution.

Thank you all anyway!

Thanks for the update. (Consistent with what kscreen-doctor reported.)
