Fullscreen issues in Undertale

Despite the benefits of playing Undertale in fullscreen mode, many players have reported issues with enabling this feature. By default, the game is locked in windowed mode, and the maximize button is typically greyed out, preventing players from easily switching to fullscreen mode.

Luckily, several methods exist to resolve this issue and enjoy Undertale in fullscreen mode. The following sections will provide detailed instructions on how to make Undertale fullscreen on various platforms, including Windows, Mac, and Linux.

How to make Undertale Fullscreen on Windows

If you are playing Undertale on a Windows computer, there are three keyboard shortcuts that you can use to make the game fullscreen. These methods have been reported to work on Windows 7, 8, 10, and 11.

Using the F4 Key

The simplest method to make Undertale fullscreen on Windows is by pressing the F4 key. This key is located on the top row of the keyboard and is used in many games to toggle fullscreen mode. Press the F4 key while playing Undertale, and the game should switch to fullscreen mode.

Using the Alt + Enter Keyboard Shortcut

Another method to make Undertale fullscreen on Windows is by using the Alt + Enter keyboard shortcut. This combination is commonly used in many applications and games to switch between windowed and fullscreen modes.

To use this keyboard shortcut, press and hold either Alt key on your keyboard, and while continuing to hold it, press the Enter key. Undertale should now switch to fullscreen mode.

Using the Fn + F4 Key Combination

If you use a laptop or a keyboard with function keys mapped to various features, you may need to use the Fn + F4 key combination to make Undertale fullscreen. The Fn key is usually located on the bottom row of the keyboard, while the F4 key is on the top row.

Press and hold the Fn key, and while continuing to hold it, press the F4 key. This combination should make Undertale fullscreen on your Windows computer.

How to make Undertale fullscreen on Mac

If you are playing Undertale on a Mac computer, making the game fullscreen slightly differs from the Windows platform. The following methods should help you achieve fullscreen mode on your Mac.

Using the Dedicated Fullscreen Button

Some Mac devices feature a dedicated fullscreen button that can switch applications, including Undertale, to fullscreen mode. If your Mac has this button, press it while playing Undertale to see if it enables fullscreen mode for the game.

Using the F4 Key

If your Mac does not have a dedicated fullscreen button or the button does not work for Undertale, you can try using the F4 key. Press the F4 key on your Mac’s keyboard while playing Undertale to see if it switches the game to fullscreen mode.

Using the Command + Enter Keyboard Shortcut

If neither the dedicated fullscreen button nor the F4 key works for making Undertale fullscreen on your Mac, you can try using the Command + Enter keyboard shortcut. This combination works for many applications and games, including Undertale.

Press and hold the Command key on your keyboard; while holding it, press the Enter key. Undertale should now switch to fullscreen mode on your Mac computer.

How to make Undertale fullscreen on Linux

Undertale can also be played on Linux systems, and making the game fullscreen on this platform is quite similar to the methods used on Windows and Mac.

Press the F4 key or the Alt + Enter keyboard combination while playing Undertale on your Linux computer to switch the game to fullscreen mode. If these methods do not work, you can try using the Fn + F4 key combination if your keyboard has function keys mapped to various features.
