4 Ways To Get Undertale Full Screen on a laptop
According to the findings of testing and research, there are four distinct paths that may be taken to transition from the compact screen mode of Undertale to the full-screen mode, which makes use of all of the area on your display.
If you find that one of these choices does not suit your needs, you should select another alternative. Leave a comment below if none of the above choices work for you so that we may assist you further.
In this article, we will discuss four different ways to play Undertale in full fullscreen mode.
1. Press the F4 Button
Undertale is a video game that, like many others, allows you to personalize your experience by assigning different keybinds to different buttons.
The fullscreen mode in Undertale may be activated by pressing the F4 key, which is one of several keybinds. You’ll locate the F4 key on the row just above the number pad on your keyboard.
It is important to keep in mind that this strategy is only compatible with the Windows operating system.
2. Press the FN and F4 Buttons
If you are using a Mac, the standard way to transition apps from a windowed mode to full-screen mode is to press the FN key in conjunction with the F4 key.
Therefore, press the FN+F4 button simultaneously on your Mac’s keyboard when playing Undertale to reach the fullscreen mode.
On Macintosh computers, the F4 button is placed in the top row of the keyboard, whereas the FN key is situated in the bottom row of the keyboard.
3. At the same time, press the ALT and ENTER keys on your keyboard.
The keyboard shortcut Alt+Enter is used most frequently to toggle between the windowed and full-screen views of an application.
To utilize this shortcut on the keyboard, press and hold either of the Alt keys, and then, while continuing to hold both keys, press the Enter key. Following that, Undertale’s window will expand to fill the entire screen.
However, just like the method before it, this method is incompatible with any operating system other than Windows.
4. For Mac laptops press the CTRL and F4 keys
At the same moment, press the CTRL and F4 keys on your keyboard.
The ALT key is not present on Mac computers; thus, you will need to utilize the CTRL key, sometimes known as the control key. On a Mac, pressing F4 by itself usually accomplishes the desired result.
The conclusion is as follows. That is all the information you require in order to play Undertale in full fullscreen mode. We’ve got you covered with a dedicated Undertale search page, where you can find additional hints and walkthroughs.

FAQs on How to fullscreen Undertale on a laptop
The following are the responses to some often-asked questions concerning this topic:
Is this a bug in the game?
Players are in agreement that there is a flaw in Undertale that impacts game play, even though the makers of the game have not formally acknowledged that there is a defect that requires fixing in the game.
Luckily, there is the straightforward workaround indicated above.
Why do I have to press FN with my F4 key?
This occurs most frequently with laptops due to the fact that a laptop’s keyboard is generally smaller than that of a desktop computer, which means that there is less room for keys.
Because of this, the row of function keys serves a number of tasks, and the FN key is required to be pressed before you may use the keys in the row in the conventional manner.
How to make Undertale full-screen on Windows 10?
In Windows 10, pressing the F4 key does not cause your game to immediately go to full-screen mode, as it did in earlier versions of Windows. Instead, it will bring up the Project screen for you to select from.
To play Undertale on full screen on Windows 10, you will need to simultaneously press the ALT key and the Enter key. This will allow you to take control of the whole display.
The plot of the video game Undertale revolves around a little boy who accidentally descends into a dangerous underworld. FIGHT or ACT your way out of conflicts while avoiding being hit by magic bullets.
Every monster has its own set of attacks, as well as its own distinct personality, and they are all standing in your way. You are free to have MERCY on them if that is what you want.
You might even make pals. But what are you going to do if you come face to face with a ruthless killer?
Undertale can be played on Windows, Mac, Linux, PS4, Vita, and Switch, and it is available in both English and Japanese.
