How To Play OSRS In Fullscreen (RuneLite)

Old School RuneScape (and by extension, RuneLite) doesn’t have a built-in full screen setting.

However, there is a plugin that lets you play in either Fullscreen Exclusive Fullscreen Borderless and I have been using it for a while without any issues.

1. Click the Settings icon in the top right of RuneLite.
2. Click the Plugin Hub icon.
3. Search for Fullscreen and click Install. You may receive a warning about it not working properly on your version of Windows but you can safely ignore this.
4. You will also need to ensure ‘Enable custom window chrome’ is disabled: Plugins > RuneLite > Window Settings > Enable custom window chrome (uncheck this).
5. Go back to the main settings page and select either Exclusive or Borderless.
6. Restart RuneLite. This is necessary to get rid of the title bar.

You can now play RuneScape in fullscreen by clicking the icon in the bottom right corner for a more immersive experience.

I can confirm that this works fine when using multiple monitors and on a 2560×1440 240Hz monitor.
