I have in my possession an old screen connected to HDMI-1 that supports up to 720p:1366x768 resolution. The main laptop screen has 1080p:1920x1080 resolution so the OS assumes it’s bigger in size although is actually smaller. Therefore, everything in the external 720p monitor looks disproportionally large compared to the laptops screen.
$ xrandr
Screen 0: minimum 16 x 16, current 3286 x 1080, maximum 32767 x 32767
eDP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 340mm x 190mm
1920x1080 143.88*+
...
HDMI-1 connected 1366x768+1920+0 (normal left inverted right x axis y axis) 410mm x 230mm
1366x768 59.62*+
...
When I try to set the external monitor to 1080p it turns off because it’s not compatible. Therefore, the next best solution I though was to use xrandr scaling option, but I believe something related to Wayland makes it impossible:
$ xrandr --output HDMI-1 --mode 1366x768 --scale 1.4056x1.4056 --panning 1920x1080

I’m currently out of ideas so I came here to ask what’s the best course of action. If this may be needed, here’s some info related to my System:
I don’t get why this is tricky. I could do this in previous versions of Fedora. It’s obviously something related to Wayland and Red Hat keeps pushing it when it sometimes feels so buggy and unfinished.
Maybe with analog displays? I don’t remember ever being able to set a monitor to accept a higher resolution than it is natively capable of showing (you could always set a lower resolution though).
I don’t want to change the native resolution of the monitor. I just want to rescale the screen so everything looks the same size. Which is the equivalent of xrandr for Wayland?
This kinda solve the problem. However, since the Tweaks option only changes the font size, now everything looks disproportionally big. How do I rescale the UI?
Thank you so much. I’ve already tried these options, but as some person said in the thread you posted, I want to scale the external monitor to 75% in order for everything to have a reasonable size and not have huge top bars and icons.
It seems that it hasn’t been implemented to GNOME yet sadly. Scaling upwards makes everything look too big. I hope they implement some way to scale downwards in the future, or give back some stable way to change back to Xorg.
gnome-session-xsession.x86_64 package it will install xorg with all dependencies you need for it just do sudo dnf install gnome-session-xsession.x86_64 in terminal after once you install go to GDM select your user and will appear right bottom corner there you can chose xorg,With xorg session maybe you can set your monitor with xrandr
