How to fullscreen undertale

Have you ever found yourself deeply immersed in a retro-inspired indie game, only to be jolted out of the experience by the constraints of a windowed screen? Maybe you’re sitting down to replay *Undertale*, eager to indulge in its charming yet haunting narrative and quirky characters, but the tiny window just isn’t cutting it. You want to be enveloped in the world of *Undertale*, fully appreciating its pixel art and soundtrack without distractions. If you’re wondering how to maximize your gaming experience by playing *Undertale* in fullscreen mode, you’re not alone–and we’ve got the answers you need.

To fullscreen *Undertale*, you can press the F4 key while the game is running. Alternatively, you can change the game settings by opening the menu, selecting ‘Options’, and then adjusting the window mode to ‘Fullscreen’.

To go into more detail, if pressing F4 doesn’t work or you prefer not to use hotkeys, navigate to the main menu of *Undertale*. From there, access ‘Options’; you’ll find a series of settings related to graphics and sound. Look for a setting labeled ‘Windowed’ and change it to ‘Fullscreen’. This action allows the game to take up your entire screen, providing a more immersive experience without the distractions of your desktop or any other open windows. Keep in mind that if your monitor’s resolution differs from the default settings of the game, you may need to adjust your display settings for optimal performance. Enjoy your journey into the Underground without any interruptions!
