How to Make Undertale Fullscreen

How to Make Undertale Fullscreen- A lot of players seem to be having an issue with Undertale. When they run the game it will be locked in windowed mode and not utilize the full size of their screen. There is a simple fix for this bug, and depending on what kind of computer you are playing on one of the solutions below should help you make Undertale fullscreen! No matter where you bought your game from, whether it was Steam or the Humble Bundle or wherever these keyboard shortcuts will work! Even if the fullscreen button on the window is greyed out or missing, these commands should force the game to go fullscreen.

If you’ve downloaded the game Undertale from Steam to your Windows PC or Mac computer or laptop, then you might be wondering how the heck you can make it big.

There’s nothing quite as frustrating as wanting to play your game fullscreen and not knowing how to maximize it’s size on your computer.

Are you having trouble figuring out how to go fullscreen with Undertale? I was confused at first too because when I first ran the game it was locked in a small windowed mode.

4 Ways To Get Undertale Full Screen

Based on my own testing and research, I have found that there are four different ways that you can go from that small screen version of Undertale to a fullscreen version that make use of your entire screen space.

Keep in mind that if one of these does not work for you, then just try one of the other options. And if none of these options work for you, then just leave me a comment and I’ll see if I can help you out.

1. Press the F4 button. This is called a function key and all of your function keys are located on the top row of your keyboard.
2. Press the FN and F4 buttons at the same time. The FN, or function button, is usually found on the lower corner of your keyboard. On Mac computers, it will be in lowercase like this: fn
3. Press the ALT and ENTER buttons at the same time. When you press these two buttons together, they switch you from small screen to full screen mode, no matter what game or program that you are running. Note: the ENTER button is called RETURN on some keyboards.
4. Press the CTRL + F4 buttons at the same time. Since Mac computers don’t have ALT keys, you have to use the CTRL, or control, key instead. Of course, F4 typically works by itself on a Mac.

One of those methods should be all you need to take your game from Undertale from bite-sized to full-sized on your laptop or computer screen.
