How to Play Deltarune in Full Screen: A Complete Guide for PC and Mac
“Deltarune,” developed by Toby Fox, is a charming and engaging RPG that captivates players with its pixel art, unique storytelling, and memorable characters. Whether you’re fighting off chaotic enemies or navigating the emotional depth of its plot, one thing’s for sure—playing in full screen elevates the experience. But not all players instantly figure out how to enable full screen. If you’re looking to remove the window borders and dive fully into the world of Deltarune, this guide has everything you need.
Below, we’ll walk you through the best ways to turn on full-screen mode on both Windows and macOS, troubleshoot common problems, and give extra tips for optimizing your gameplay experience.
Why Full Screen Enhances Your Deltarune Experience
By default, Deltarune opens in windowed mode, which means the game only takes up a portion of your screen. This is fine for casual play, but it can be distracting when you’re engaged in tense boss fights or deep in story-driven scenes. Full-screen mode removes all outside visual clutter and allows the game’s vivid pixel graphics and soundtrack to fully immerse you.
Key reasons to switch to full screen include:
- Improved visual immersion
- More responsive controls due to fewer background interruptions
- Better emotional engagement with the narrative and visuals
- Cleaner screenshots and recordings for content creators
Now that we know why it’s worth the effort, let’s dive into how you can enable it on different platforms.
How to Enable Full Screen in Deltarune on Windows
Windows users have a couple of reliable ways to switch Deltarune into full-screen mode. Whether you’re using a gaming laptop or a desktop PC, the following methods should work for most setups.
1. Use Keyboard Shortcuts
Press F4
The simplest and most direct way to toggle full screen is by pressing the F4 key while in-game. This will immediately expand the game window to occupy the entire screen.
Tip: If you’re using a laptop, especially one with compact keys, you might need to hold the Fn (Function) key while pressing F4.
Try Alt + Enter
If F4 doesn’t work for some reason, another universal shortcut for games is Alt + Enter. Pressing both keys at the same time should toggle between windowed and full-screen modes.
This shortcut is widely compatible and works for many older games as well, making it a good fallback if the first option fails.
2. Use the In-Game Menu (If Available)
In later parts of Deltarune, particularly once you enter the Dark World, the in-game settings menu becomes available. From there, you can enable full screen manually:
- Press ESC or Pause to open the main menu
- Navigate to Settings or Options
- Look for Screen Mode or Fullscreen
- Switch the setting to On
Not all versions of the game will include this option in the early areas, but it’s worth checking if the keyboard shortcuts fail.
How to Enable Full Screen in Deltarune on macOS
For Mac users, toggling full screen involves slightly different commands. Thankfully, Apple has built full-screen functionality into macOS itself, so it’s easy to manage.
1. Use Mac Keyboard Shortcuts
Press Command + Control + F
This macOS-specific combination enables full screen for most applications, including Deltarune. Simply press Command + Control + F while the game window is active, and it should stretch to fill the entire display.
If you want to return to windowed mode, press the same keys again.
2. Use the Menu Bar
If you’d rather use your mouse:
- Move your cursor to the top of the screen to reveal the menu bar
- Click on View
- Select Enter Full Screen
This method is ideal for players who prefer navigating through menus instead of remembering key combos.
Common Problems When Entering Full-Screen Mode (And How to Fix Them)
Despite the relatively easy methods to toggle full-screen mode, some players may face hiccups. Below are some frequent issues and how to resolve them.
Issue #1: Game Looks Stretched or Squashed
If the game appears distorted after switching to full screen, it’s usually due to mismatched resolution or incorrect display scaling.
Fix:
- Set your display scaling to 100% in Windows Settings
- Adjust your screen resolution to match your monitor’s native settings
- Avoid third-party screen-scaling apps
Issue #2: Game Runs Too Fast in Full Screen
Some users on high refresh rate monitors (e.g., 144Hz or 240Hz) might notice that the game speeds up unnaturally in full screen.
Fix:
- Go to Display Settings on your PC
- Temporarily set your monitor’s refresh rate to 60Hz while playing
- Alternatively, set compatibility settings for the game executable
Issue #3: Keyboard Shortcuts Don’t Respond
Laptop users may discover that pressing F4 or Alt + Enter does nothing.
Fix:
- Try using Fn + F4 or Fn + Alt + Enter
- Check your laptop’s BIOS/UEFI to ensure function keys are set to work as standard
- Explore your manufacturer’s software (like Lenovo Vantage or HP Quick Launch) for keyboard settings
Issue #4: Flickering or Black Screen on Full Screen
If switching to full screen causes visual glitches or even crashes, it could be related to your graphics driver.
Fix:
- Update your GPU drivers (NVIDIA, AMD, or Intel)
- Run the game as Administrator
- Try disabling Fullscreen Optimization via right-click > Properties on the game file
Bonus Tips for the Best Full-Screen Gameplay Experience
Full screen isn’t just about hitting a few keys—it’s about setting up your environment for the best possible playthrough. Here’s how you can level up your gaming session:
1. Use a Game Controller
Deltarune is compatible with most modern controllers. When paired with full screen, a gamepad can deliver a console-like experience.
2. Turn Off Notifications
Close unnecessary apps or enable “Focus Assist” or “Do Not Disturb” to eliminate pop-ups that can pull you out of the immersive world.
3. Adjust Brightness and Color
Your monitor’s brightness, contrast, and gamma settings can deeply affect how the game looks. Calibrate them for pixel-perfect visuals.
4. Use Headphones
Deltarune’s soundtrack is a massive part of the experience. Wearing headphones helps you catch every music cue and sound effect.
Full Screen vs. Windowed Mode: Which is Better?
While full screen is usually preferred for immersion, windowed mode also has its benefits—especially for multitasking. Here’s a quick comparison:
| Feature | Full Screen | Windowed Mode |
|---|---|---|
| Immersion | ✅ High | ❌ Low |
| Performance | ✅ Often better | ❌ May be lower |
| Accessibility | ❌ Harder to multitask | ✅ Easy to alt-tab |
| Resolution Scaling | ✅ Optimized | ❌ May look blurry |
In short, choose full screen when playing for long sessions and windowed when you’re multitasking.
