Use In-Game Settings

One of the easiest ways to toggle fullscreen mode in Minecraft is through the in-game settings menu. Simply open the Options menu and select Video Settings. Here you'll find a toggle to turn Fullscreen mode "On" or "Off". Toggling this switch will immediately activate or deactivate fullscreen. You can verify by checking if the Minecraft window now takes up the entire screen or is contained within a smaller movable window.

Additionally, while already in-game, you can press the F11 key on your keyboard to quickly toggle between fullscreen and windowed mode [1]. This keyboard shortcut functions the same as going through the in-game video settings menu. Pressing F11 will switch to fullscreen if you're currently windowed, or revert to windowed if you're currently fullscreened. It's a handy shortcut to quickly change your display mode without navigating menus.

So in summary, use the Options > Video Settings menu or the F11 shortcut to easily toggle fullscreen on or off in Minecraft.

Keyboard Shortcuts

There are a couple keyboard shortcuts that can be used to easily toggle fullscreen mode in Minecraft:

Pressing Alt + Enter will switch between fullscreen and windowed mode. This is a quick and easy way to toggle the display while playing the game. Just hit Alt + Enter whenever you want to change the view.[1]

On Windows, the F11 key can also be used to toggle fullscreen mode on and off. Simply tap F11 to switch between fullscreen and windowed display. This keyboard shortcut works for both the Java and Bedrock editions of Minecraft on PC.[2]

These keyboard shortcuts allow players to quickly change the fullscreen view without having to open up the options menu. Both Alt + Enter and F11 are easy to access keys that can make going fullscreen a simple process.

Fix Fullscreen Issues

Minecraft sometimes has problems displaying properly in fullscreen mode. Here are some tips to troubleshoot and fix common fullscreen issues:

If Minecraft appears blurry or zoomed in when in fullscreen, try disabling display scaling for javaw.exe. To do this, right click the Minecraft launcher shortcut, go to Properties > Compatibility, and check "Disable display scaling on high DPI settings". This will force the game to render at your monitor's native resolution.

If you get a black screen when toggling to fullscreen mode, your graphics drivers may need an update. Go to the website of your graphics card manufacturer (NVIDIA, AMD, Intel) to download and install the latest drivers.

Using borderless windowed mode can fix fullscreen issues if you have a multi-monitor setup. This makes the game act like fullscreen but without being confined to one display. To enable it, go to Video Settings in-game and choose "Borderless" under Fullscreen Mode.[1]

Troubleshooting fullscreen problems can help get Minecraft running smoothly in fullscreen on your system.

Optimize Fullscreen Performance

[ "To optimize your framerate and performance while playing Minecraft in fullscreen, there are a few key things you can do:"]

[ "Lowering your in-game resolution is one of the easiest ways to boost FPS in fullscreen. Run Minecraft at lower resolutions like 720p or 900p if your default resolution is causing low framerates. This reduces the load on your GPU and can lead to sizable gains."]

[ "Closing other open programs before launching Minecraft can also help prevent FPS drops. Browsers, launchers and background apps can all siphon away crucial system resources in the background that the game needs to run smoothly."]

[ "Using performance-enhancing Minecraft mods like Sodium, Lithium or Optifine can optimize and increase FPS in fullscreen mode. These mods reduce overhead, optimize rendering and unlock video settings not available in vanilla Minecraft."]

By lowering resolution, closing other apps and installing mods, you can maximize and stabilize your framerate when playing fullscreen Minecraft.

Use Second Monitor

Playing Minecraft in fullscreen mode on a dual monitor setup takes a couple extra steps. You'll need to move the game over to your secondary display first. According to this article, there are two main ways to do this:

- Drag the Minecraft window from your primary display over to your secondary monitor. Once it's positioned on the external screen, toggle fullscreen mode on. Minecraft should now take up the entire second monitor.

- Use the Windows shortcut Win + Shift + Left/Right Arrow to move the Minecraft window between monitors. After pressing the shortcut to move the game over to your secondary display, toggle fullscreen mode on to make it fill that monitor.

This allows you to play Minecraft fullscreen on one display while still accessing other apps and programs on your main monitor. It's useful if you want to reference gameplay tips or chat on a second screen while playing fullscreen on the other.
