Hello helpful fedora people,
I’m trying to set up multiple displays using the “mirror” feature, where content is copied across both my screens, but I have an issue with display resolution, specifically the aspect ratio.
My laptop screen is 1366 x 768 (16:9)
The external display is 1920 x 1080 (16:9)
If I click the “Mirror” option in display settings, it gives me 2 options:
1024x768 (4:3)
or 800 x 600 (4:3)
if I choose either of these options and apply it, my laptop screen is cropped to a 4:3 ratio(black bars on the sides), while the external monitor is stretched to fit a 4:3 ratio.
Is there a way I can add more options to the display settings for mirroring screens, so I can use one with a 16:9 ratio? Or something else I can do about the issue?
System information:
OS: Fedora Linux 41 (Workstation edition)
Gnome Version: 47
Windowing system: Wayland
Kernel: Linux 6.13.4-200.fc41.x86_64
I’ve tried connecting the external display 2 different ways - with a vga-vga cable, and a displayport-dvi cable. I also tried a different external monitor, I get the same issue.
I’m quite new to fedora. If I’m posting this in the wrong place, please let me know where I should be posting instead.
Thanks in advance for any help or suggestions you can offer.
(P.S. the option should really be to “duplicate” the display, not “mirror” shouldn’t it? “Mirror” makes me think the content will be flipped)
So, you got me curious to see how this displayed on my machine with the following monitors:
- Primary: 2560x1440
- Secondary: 1920x1080
To my surprise, when I try to mirror I also see the same two options:
That seemed deeply strange to me since both my displays are 16:9 so surely there’d be other options? That’s when I noticed my primary display only lists the following resolutions in Gnome settings:
- 2560x1440
- 1024x768
- 800x600
That seems deeply strange because I’m sure this monitor supports far more under Windows. Maybe a weird Nvidia issue on my end? Not sure.
My secondary monitor shows that it supports several others, but the two 4:3 options are the only to resolutions that the two monitors appear to have in common… I wonder if you’re running into the same issue. Can you check which resolutions Gnome says the two of your monitors both support? I’m going to guess it’s those same two 4:3 options.
Also +1 for Bee and PuppyCat.
We do not know what you have for GPU nor the drivers used.
Please post (as preformatted text using the </> button) the output of inxi -Fzxx so we may have the additional information required.

Thanks for your response Eric,
Good guess! yes, this looks like this describes my issue as well. The resolutions offered are simply the two options which both displays have in common. Here’s a table of the options I have for both screens on Fedora:
| Built-in laptop screen |
External screen |
| 1366 x 768 (16:9) |
1920 x 1080 (16:9) |
| 1280 x 720 (16:9) |
1680 x 1050 (16:10) |
| 1024 X 768 (4:3) |
1440 x 900 (16:10) |
| 800 X 600 (4:3) |
1280 x 800 (16:10) |
|
1152 x 864 (4:3) |
|
1024 x 768 (4:3) |
|
800 x 600 (4:3) |
I also checked what options Windows gives me (I’m dual booting this laptop so I’m able to check). Here’s the table of options Windows offers me:
| Built-in laptop screen |
External screen |
| 1366 x 768 |
1920 x 1080 |
| 1360 x 768 |
1680 x 1050 |
| 1280 x 768 |
1600 x 900 |
| 1280 x 720 |
1440 x 900 |
| 1280 x 600 |
1400 x 1050 |
| 1024 x 768 |
1366 x 768 |
| 800 x 600 |
1360 x 768 |
|
1280 x 1024 |
|
1280 x 960 |
|
1280 x 800 |
|
1280 x 768 |
|
1280 x 720 |
|
1280 x 600 |
|
1024 x 768 |
|
800 x 600 |
It seems to offering a few more for both screens, and when I set it to duplicate across screens, it defaults to 1920 x 1080 for both (even though it didn’t previously offer this as a laptop screen resolution.
I started looking for ways to add screen resolutions manually and found this post on stackexchange: vmware - Manually add a resolution to Gnome with Wayland - Super User which sounds like the same issue - the answer by Paul Rougieux might work, I’m going to give that a try, wish me luck!
