Steam offers one of the largest gaming libraries on PC, giving players access to thousands of titles across every genre imaginable. However, not every game launches with the display mode you prefer. Some games automatically open in full screen, while others may start in borderless or windowed mode. For many players, this can impact performance, multitasking, screen resolution, or overall gameplay comfort.
Knowing how to control whether your Steam games launch in windowed mode, borderless windowed mode, or full screen can significantly improve your gaming experience. Windowed mode is useful for multitasking, streaming, troubleshooting, or using multiple monitors, while full screen often provides better immersion and may improve gaming performance in certain situations.
Fortunately, Steam and most PC games offer multiple ways to control startup display modes. These include in-game settings, launch options, Steam shortcuts, graphics configuration files, and third-party tweaks.
This guide covers everything you need to know about starting Steam games in your preferred display mode, including setup methods, troubleshooting tips, advanced launch commands, and optimization suggestions for Windows 11 and modern gaming PCs.
Understanding Display Modes in Steam Games
Before changing startup settings, it is important to understand the three main display modes commonly used in PC gaming.
Full Screen Mode
Full screen mode dedicates your entire monitor to the game, often delivering:
- Better immersion
- Potential performance improvements
- Direct GPU resource allocation
- Lower desktop distractions
However, switching between apps can be slower.
Windowed Mode
Windowed mode runs the game inside a movable desktop window.
Benefits include:
- Easy multitasking
- Quick Alt+Tab switching
- Better accessibility for streamers
- Multiple monitor convenience
Downsides may include:
- Slightly reduced performance
- Visible borders
- Less immersion
Borderless Windowed Mode
This combines the benefits of both.
Advantages include:
- Seamless monitor fit
- Fast task switching
- Cleaner appearance
- Improved multitasking
For many users, borderless windowed mode is the ideal compromise.
Why You May Want To Start Steam Games in Windowed Mode
There are several reasons users prefer windowed startup:
- Streaming or recording gameplay
- Using Discord simultaneously
- Monitoring performance tools
- Troubleshooting crashes
- Working with multiple displays
- Easier web browsing while gaming
- Faster switching between applications
Windowed mode is especially useful for strategy games, MMOs, simulation games, and productivity-heavy setups.
Why Full Screen May Be Better for Some Players
For competitive or graphics-intensive games, full screen often remains preferable.
Advantages include:
- Maximum immersion
- Better response times in some titles
- Improved FPS in certain games
- Fewer distractions
- Better HDR support in supported games
Games like shooters, racing titles, or cinematic adventures often perform best in full screen.

- Works for most games
Method 2: Use Steam Launch Options
Steam allows players to force display settings through launch commands.
To access launch options:
- Open Steam
- Go to Library

- No settings menus required
Limitations:
- Not supported by all games
- May not persist after restart
Method 4: Edit Game Configuration Files
Some games store video settings in config files.
Common file locations:
- Documents folder
- AppData
- Game install folder
- Steam userdata folder
Typical settings:
Fullscreen=true
Windowed=false
Borderless=falseModify these values based on your preference.
Important:
- Back up files first
- Incorrect edits may cause launch problems
Method 5: Modify Desktop Shortcut Properties
Some Steam games can be adjusted via shortcut target parameters.
Example:
"C:\Program Files (x86)\Steam\steam.exe" -applaunch GAMEID -windowedThis approach is more advanced but useful for custom setups.
Troubleshooting Games That Won’t Launch Properly
Sometimes games may ignore startup preferences.
Common solutions:
Game stuck in wrong resolution:
- Delete config files
- Verify game files
- Reinstall graphics drivers
Black screen:
- Force windowed mode
- Lower resolution
- Disable overlays
Steam launch options not working:
- Check correct syntax
- Confirm game supports commands
- Remove conflicting mods
Verifying Steam Game Files
Corrupted files can affect display behavior.
Steps:
- Steam Library
- Right-click game
- Properties
- Installed Files
- Verify integrity of game files
This often restores proper launch settings.
GPU Control Panel Adjustments
Graphics software can also affect display modes.
NVIDIA:
- NVIDIA Control Panel
- Manage 3D settings
AMD:
- Radeon Software
- Display settings
Intel:
- Graphics Command Center
These tools can override scaling, refresh rate, or aspect ratio.
Multi-Monitor Considerations
For dual-monitor users:
Windowed mode:
- Better flexibility
- Easier secondary screen use
Full screen:
- Better focus
- May lock cursor
Borderless:
- Best balance
Monitor arrangement can also impact startup behavior.
Performance Considerations
Full Screen:
- Potentially best FPS
- Lower system overhead
- Better exclusive GPU control
Windowed:
- More desktop resource sharing
- Slightly lower performance
Borderless:
- Convenient
- Usually minor FPS difference
Modern systems often handle all modes well, but competitive players may still prefer exclusive full screen.
Steam Big Picture Mode and Steam Deck Considerations
For controller users:
- Big Picture mode may override launch preferences
- Steam Deck often uses Linux compatibility layers
- Proton settings may affect display modes
- External monitor setups may need additional tweaks
Best Practices for Steam Display Customization

- Test multiple display modes
- Disable unnecessary overlays
Final Thoughts
Starting Steam games in windowed or full screen mode gives you greater control over how your games perform and fit into your daily workflow. Whether you prioritize immersion, multitasking, streaming, or troubleshooting, Steam provides several reliable methods for customizing launch behavior.
For most users, in-game settings remain the easiest solution, while launch options and config file edits offer advanced control when needed. Windowed mode is excellent for flexibility, full screen is ideal for immersion and performance, and borderless windowed often provides the best overall balance.
By understanding your options and learning how different games handle display settings, you can create a smoother, more personalized gaming experience across your entire Steam library.
