Borderless Window

by nimueller

Borderless Window swaps Minecraft's standard fullscreen for a borderless version, aimed at Forge and NeoForge players who run more than one monitor.

ForgeNeoForgeClient-side onlyMIT LicenseOpen source1.14.4 – 1.21.11

What it does

When the game switches to fullscreen, through F11 or the fullscreen option in the video settings, the window is drawn without borders instead of taking over the display in a separate video mode. The default fullscreen minimizes the game as soon as it loses focus, while this version keeps the window in place, so another program on a second monitor can be used without leaving Minecraft and other windows can be stacked on top of it.

The mod works alongside OptiFine. Borderless fullscreen is a client change, so only the player's game needs the jar and a server does not need it. The mod is released under the MIT License and is open source, with its source code and issue tracker publicly available. Files cover 1.14.4 – 1.21.11 across 34 game versions, with the latest Forge and NeoForge builds dated 2026-02-10.

Key features

  1. Borderless fullscreen

    Fullscreen mode is drawn as a borderless window that fills the display without switching the monitor's video mode.

  2. No minimizing on focus loss

    The window stays open when another program takes focus, which suits setups with several monitors.

  3. Stackable windows

    Separate applications can be layered over the game window while it is in fullscreen.

  4. Automatic switching

    No setting is needed: the window becomes borderless whenever fullscreen is turned on from F11 or the video settings.

Use cases

Multi-monitor play

Who it’s for: Players on Forge or NeoForge who run Minecraft on a multi-monitor setup and want fullscreen without the window minimizing when focus moves to another program.

Questions

Does Borderless Window need OptiFine?

No. The mod works with Forge and OptiFine, but OptiFine is not required to run it.

Does a server need Borderless Window installed?

No. The mod is client-side only, so only the player's game needs the jar.

Why can fullscreen performance drop with this mod?

The window library Minecraft uses can enable VSync in borderless fullscreen, which may cause significant performance issues. The author has no fix until a new library version is released.

Does the mod work on macOS?

No. Borderless Window is disabled on macOS, while Windows and Linux under X11 or Wayland are supported.
