Guide: How to fix UI scaling

[rikkarth]

Solution

In .config/hypr/monitors.conf change env = GDK_SCALE,2 to env = GDK_SCALE,1, specially if you're in 1080p monitors.

The change isn't immediately reflected, relaunch Hyprland either in System (SUPER+ALT+SPACE > System > Relaunch), if you're unsure what to do restart your computer.

Alternative Steam

This is not required if you performed the main solution successfully.

Open Steam and go to Steam -> Settings

Go to Interface and toggle OFF Scale text and Icons to match monitor settings

You should be prompted to restart Steam, otherwise restart.

I'm pretty sure changing env = GDK_SCALE, 1 solves the issue too, at least for me, since by default it runs on 2, and I'm running Omarchy on a 1080p screen. You can find this setting by navigating to setup -> monitors

I changed the windowrule from float to tile in the ./local/share/omarchy/default/hypr/apps/steam.conf file and it helped a lot.

I will provide GDK_SCALE=1 as first option to fix scaling for most applications and revamp this.

But you don't need to change the default, in fact defaults may be overwritten during updates.

Oh GOD thats much better, THANKS!

Thanks this was perfect

Thanks a ton! Was really struggling with this and had to resort to big picture mode.

This should be a default if thats event possible causes its in steam

I have the same issue with prusa slicer. I couldnt find any gui settings in the app or any config files.
this is my hypr/monitors.config

env = GDK_SCALE,2
monitor= DP-2, 2560x1440@165, auto, 1
monitor= HDMI-A-1, 1920x1080@144, auto-left, 1

If anyone on Omarchy 4 / Hyprland is seeing their display scaling change after locking/unlocking — for example from scale = 1 to 1.25 or something odd like 0.999999992 — this is what fixed it for me.

My monitor config had been generated by nwg-displays and looked like this:

hl.monitor({
    output = "eDP-1",
    mode = "1920x1080@60.0",
    position = "0x0",
    scale = 1,
})

Hyprland itself handled this correctly. Running:

hyprctl reload

would immediately restore the display to scale = 1.

The problem appeared after lock/unlock. Omarchy's monitor recovery logic was not correctly picking up the scale from the multiline hl.monitor({...}) entry, and could restore a previously remembered scale instead.

Fix

First back up the config:

cp ~/.config/hypr/monitors.lua ~/.config/hypr/monitors.lua.bak

Then change the monitor definition so the entire rule is on one line:

hl.monitor({ output = "eDP-1", mode = "1920x1080@60.0", position = "0x0", scale = 1 })

Then remove Omarchy's remembered internal-monitor scale:

rm -f ~/.local/state/omarchy/toggles/hypr/internal-monitor-scale

Reload Hyprland:

hyprctl reload

You can confirm the result with:

hyprctl monitors all -j | jq '.[] | select(.name=="eDP-1") | {name, width, height, refreshRate, scale}'

Mine now stays at:

scale = 1

even after locking and unlocking.

Important

Avoid opening nwg-displays and saving the layout again for now, because it may regenerate monitors.lua using the multiline format.

So in short:

Multiline nwg-displays monitor rule → Omarchy recovery doesn't correctly pick up the configured scale → stale scale gets restored after lock/unlock.

One-line hl.monitor(...) rule + deleting internal-monitor-scale fixed it permanently for me.

Hopefully this saves someone else from having to run hyprctl reload every time they unlock their machine.

It's already set to 1 but regardless, the scaling is messed up. Disabling scaling from Steam fixes it, but I would think this is a sub-optimal fix
