Understanding Full Screen Modes: Exclusive vs. Borderless Windowed

Before we delve into the “how-to,” it’s important to understand the fundamental difference between the two primary full screen modes: exclusive full screen and borderless windowed (or “fullscreen windowed”). Each offers distinct advantages and disadvantages, impacting performance, responsiveness, and multitasking capabilities.

Exclusive Full Screen: The Performance Champion

Exclusive full screen mode grants the game exclusive control over your display. This typically results in the best possible performance because the game bypasses the Windows Desktop Window Manager (DWM), which handles window composition and can introduce input lag. Think of it as the game having direct access to your graphics card’s power.

Benefits:

Potentially higher frame rates.
Reduced input lag.
Optimal for performance-critical games.

Drawbacks:

Slower alt-tabbing: Switching to other applications can take longer.
Compatibility issues with some overlays or multi-monitor setups.

Borderless Windowed: The Multitasking Master

Borderless windowed mode, on the other hand, runs the game in a window that is stretched to cover the entire screen. While it might appear identical to exclusive full screen visually, the game still operates within the Windows environment. This allows for seamless alt-tabbing and easier interaction with other applications.

Benefits:

Fast and seamless alt-tabbing.
Better compatibility with overlays (Discord, Steam Overlay, etc.).
Smoother multi-monitor integration.

Drawbacks:

Slightly lower performance compared to exclusive full screen.
Potentially increased input lag.

Methods for Enabling Full Screen in Steam Games

Now that you understand the different modes, let’s explore the various methods to configure your games for full screen enjoyment. The specific steps might vary slightly depending on the game, but the core principles remain consistent.

In-Game Settings: The First Port of Call

The most common and reliable method is to adjust the display settings directly within the game’s options menu.

Launch the game you want to play in full screen.
Navigate to the game’s settings menu. This is usually found under “Options,” “Settings,” “Video Settings,” or something similar.
Look for display-related options such as “Display Mode,” “Full Screen,” or “Windowed Mode.”
Select “Full Screen” or the equivalent option to enable exclusive full screen. Alternatively, choose “Borderless Windowed” if you prefer that mode.
Apply the changes and restart the game if prompted.

Pro Tip: While in the settings, ensure that the resolution is set correctly to match your monitor’s native resolution for the sharpest image quality.

Steam Launch Options: A Powerful Override

Steam launch options provide a way to force specific game settings before the game even starts. This can be useful for overriding default configurations or troubleshooting display issues.

In your Steam library, right-click on the game you want to configure.
Select “Properties.”
In the Properties window, click on the “General” tab.
Under the “Launch Options” section, enter the following commands:
- -fullscreen (forces full screen mode)
- -windowed (forces windowed mode, useful for reverting changes if full screen causes problems)
- -noborder (removes the window border, effectively creating borderless windowed mode if used in conjunction with a resolution setting)
- -w [width] -h [height] (sets the game resolution, e.g., -w 1920 -h 1080)
Close the Properties window and launch the game.

Important Note: The effectiveness of these launch options can vary from game to game. Some games might ignore them entirely.

Keyboard Shortcuts: The Quick Fix

Sometimes, a simple keyboard shortcut is all you need to toggle between full screen and windowed mode.

Alt + Enter: This is the most common shortcut for toggling full screen mode in many applications, including Steam games. Try pressing Alt + Enter while the game is running.

Caveat: This shortcut might not work in all games, especially those that have custom input mappings or handle display modes differently.

Graphics Card Control Panel: The Global Approach

Your graphics card’s control panel (Nvidia Control Panel or AMD Radeon Settings) offers settings that can impact how games are displayed. While not directly forcing full screen, adjusting certain settings can help ensure proper full screen behavior.

Nvidia Control Panel:

Right-click on your desktop and select “Nvidia Control Panel.”
Navigate to “Adjust desktop size and position” under the “Display” section.
Ensure that the “Scaling” option is set to “Full-screen” and that the “Perform scaling on” option is set to “GPU.” This ensures that your graphics card handles the scaling, which can improve performance and prevent display issues.
Under “Manage 3D settings,” you can also adjust global settings that might affect full screen behavior, such as “Preferred refresh rate” and “Vertical sync.”

AMD Radeon Settings:

Right-click on your desktop and select “AMD Radeon Settings.”
Navigate to the “Display” tab.
Ensure that the “Scaling Mode” is set to “Full Panel.”
Under the “Graphics” tab, you can adjust global graphics settings that might affect full screen behavior.

Note: Be cautious when making changes in your graphics card control panel, as incorrect settings can negatively impact your overall system performance.

Troubleshooting Full Screen Issues

Even with the methods outlined above, you might still encounter issues with getting your Steam games to run in full screen. Here’s a comprehensive troubleshooting guide to address common problems.

Game Not Launching in Full Screen

If the game consistently launches in windowed mode despite your attempts to force full screen, consider the following:

Conflicting Settings: Check both the in-game settings and Steam launch options for conflicting commands. For example, if you have -windowed in the launch options, it will override any full screen settings in the game.
Driver Issues: Outdated or corrupted graphics drivers can cause display problems. Update to the latest drivers from Nvidia or AMD’s website. A clean driver install (uninstalling the old drivers completely before installing the new ones) is often recommended.
Game Configuration Files: Some games store their display settings in configuration files. Locating and editing these files can sometimes resolve persistent full screen issues. The location of these files varies from game to game. Consult the game’s documentation or online forums for specific instructions.
Compatibility Mode: Try running the game in compatibility mode for an older version of Windows. Right-click on the game’s executable file, select “Properties,” go to the “Compatibility” tab, and experiment with different compatibility settings.
Admin Privileges: Running the game as an administrator can sometimes resolve permission-related issues that might prevent it from running in full screen. Right-click on the game’s executable file and select “Run as administrator.”
Third-Party Applications: Overlays or other third-party applications can sometimes interfere with full screen mode. Try disabling these applications temporarily to see if they are causing the problem.

Game Switching to Windowed Mode Unexpectedly

If the game starts in full screen but switches to windowed mode during gameplay, consider these factors:

Alt-Tabbing: Accidentally pressing Alt + Tab can switch the game to windowed mode.
Notifications: Windows notifications can sometimes force the game to minimize or switch to windowed mode. Consider disabling notifications temporarily while gaming.
Overlays: Overlays from applications like Discord or Steam can sometimes cause the game to switch to windowed mode. Try disabling these overlays or adjusting their settings.
Background Processes: Resource-intensive background processes can sometimes cause the game to lose focus and switch to windowed mode. Close unnecessary applications before launching the game.

Black Bars or Incorrect Resolution

If the game is running in full screen but displays black bars around the edges or the resolution is incorrect, try these solutions:

Resolution Settings: Ensure that the game’s resolution is set to your monitor’s native resolution.
Scaling Settings: Check your graphics card control panel’s scaling settings (as described above) to ensure that scaling is being performed correctly.
Aspect Ratio: Some games have aspect ratio settings that can affect how the image is displayed. Experiment with different aspect ratio settings to see if they resolve the issue.
Monitor Settings: Check your monitor’s settings to ensure that it is not applying any scaling or aspect ratio adjustments that might be interfering with the game’s display.

Multi-Monitor Issues

If you are using multiple monitors, ensure that the game is being displayed on the correct monitor and that the resolution is set correctly for that monitor. Also, experiment with different display arrangements in Windows settings (e.g., extending the desktop vs. duplicating the display).

The Importance of Monitor Drivers

While less common than graphics driver issues, outdated or missing monitor drivers can also contribute to display problems, including full screen issues. Ensure that your monitor is properly recognized by Windows by installing the correct drivers, which can usually be found on the monitor manufacturer’s website.

Advanced Troubleshooting: Digging Deeper

If you’ve exhausted all the standard troubleshooting steps and are still experiencing full screen problems, it might be necessary to dig deeper. This could involve:

System File Checker (SFC): Running the System File Checker can identify and repair corrupted system files that might be causing display issues.
Clean Boot: Performing a clean boot can help identify if a third-party application or service is interfering with the game’s display.
Hardware Diagnostics: In rare cases, hardware problems (such as a failing graphics card) can cause display issues. Running hardware diagnostics can help identify potential hardware failures.

Getting your Steam games to run in full screen is usually a straightforward process, but sometimes requires a bit of troubleshooting. By understanding the different full screen modes, utilizing in-game settings and Steam launch options, and employing the troubleshooting techniques outlined in this guide, you can overcome most full screen challenges and enjoy your games in their full, immersive glory. Remember to keep your drivers updated, experiment with different settings, and don’t be afraid to consult online resources or the game’s community for further assistance. Happy gaming!

Why isn’t my Steam game launching in full screen?

There are several reasons why your Steam game might not be launching in full screen. One common cause is incorrect in-game settings. Many games have their own graphics options where you can choose between windowed, borderless windowed, and full-screen modes. Ensure that the game’s settings are configured to use full screen mode. Some games may also have a “launch option” within Steam settings that overrides the in-game settings, or the game might be defaulting to a resolution that is not supported by your monitor when in full screen, causing issues.

Another potential issue could be interference from other programs running in the background, particularly those that overlay on top of the game. Programs like Discord, MSI Afterburner, or even some antivirus software can sometimes prevent a game from properly switching to full screen. Try temporarily disabling these programs to see if that resolves the issue. Additionally, outdated graphics drivers or conflicting display settings in Windows can also contribute to this problem; updating your drivers and verifying display configurations can help.

How do I force a Steam game to launch in full screen?

You can often force a Steam game to launch in full screen by utilizing launch options. In your Steam library, right-click on the game’s title and select “Properties.” In the “General” tab, find the “Launch Options” section and enter “-fullscreen.” This command tells Steam to specifically instruct the game to launch in full screen mode upon startup. Remember to test the game after adding the option to ensure it takes effect.

If the “-fullscreen” command doesn’t work, try other launch options that might be more specific to the game engine. You could also experiment with “-w [width] -h [height]” replacing [width] and [height] with your monitor’s resolution (e.g., “-w 1920 -h 1080”). Another useful option is “-noborder,” which can force a borderless windowed mode that simulates full screen. Combining launch options might be necessary to achieve the desired result, depending on the game’s specific implementation.

What’s the difference between “Full Screen” and “Borderless Windowed” modes?

The primary difference between full screen and borderless windowed mode lies in how the game interacts with the operating system. In true full screen mode, the game has exclusive control over your display. This usually results in slightly better performance, as the operating system dedicates more resources to the game, and reduces input latency. However, alt-tabbing out of a true full screen game can sometimes cause delays or even crashes as the system readjusts.

Borderless windowed mode, on the other hand, runs the game in a window that’s stretched to fill the entire screen. This mode doesn’t have exclusive control of the display, allowing for much faster and smoother alt-tabbing as the game remains active in the background. While the performance difference is often negligible on modern hardware, some users may experience a slight decrease in frame rates compared to true full screen. Borderless windowed mode also allows easy access to secondary monitors.

How can I troubleshoot a game stuck in windowed mode despite being set to full screen?

If a game is consistently stuck in windowed mode despite being configured for full screen, start by verifying the game’s integrity through Steam. Right-click on the game in your library, select “Properties,” then go to the “Local Files” tab and click “Verify integrity of game files.” This process will check for and replace any corrupted or missing files that might be causing the issue. Additionally, ensure your graphics card drivers are up to date, as outdated drivers are a frequent cause of display problems.

Another troubleshooting step involves checking your Windows display settings. Ensure that your monitor is set to its native resolution and that scaling is set to 100%. Sometimes, custom scaling settings can interfere with the game’s ability to properly display in full screen. Furthermore, try running the game as an administrator, as this can grant it the necessary permissions to access and utilize the full screen mode. Finally, check if any third-party applications are interfering with the game’s display settings.

Why does my game flicker or tear in full screen?

Screen tearing in full screen typically occurs when the game’s frame rate exceeds your monitor’s refresh rate, causing the display to render portions of different frames simultaneously. This results in a visible horizontal tear across the screen. Flickering can also be a related issue, often caused by rapid changes in brightness or contrast due to driver problems or improper settings.

The most common solution for screen tearing is to enable VSync (Vertical Synchronization) within the game’s graphics settings or through your graphics card control panel (Nvidia Control Panel or AMD Radeon Settings). VSync limits the game’s frame rate to match your monitor’s refresh rate, preventing tearing. If VSync introduces input lag, consider using adaptive VSync (available in Nvidia drivers) or AMD FreeSync/Nvidia G-Sync if your monitor supports it. Ensure your monitor drivers are installed correctly, also check the refresh rate selected is appropriate to what your monitor can handle.

How do I change the resolution in full screen mode?

Changing the resolution in full screen mode is usually done through the game’s graphics settings menu. Look for options related to display, resolution, or graphics. Typically, you’ll find a dropdown menu or a list of available resolutions supported by your monitor. Select the desired resolution and apply the changes. Ensure the selected resolution matches your monitor’s aspect ratio to avoid stretching or distortion.

If the game doesn’t offer the resolution you want, or if changing the resolution in the game’s settings doesn’t work, you can try forcing a specific resolution using Steam launch options. Add the launch options “-w [width] -h [height]” (e.g., “-w 1920 -h 1080”) to the game’s properties in Steam, replacing [width] and [height] with the desired resolution values. Also, adjust your desktop resolution settings in Windows to the same resolution as the game if issues persist.

What should I do if my game crashes when entering full screen?

Game crashes when entering full screen can indicate a variety of underlying issues. One common culprit is outdated or corrupted graphics drivers. Begin by updating your graphics drivers to the latest stable version from the manufacturer’s website (Nvidia, AMD, or Intel). If you recently updated drivers and the crashes started occurring after the update, consider rolling back to a previous version that was known to be stable.

Another potential cause is hardware incompatibility or insufficient system resources. Verify that your computer meets the game’s minimum and recommended system requirements. Also, try closing unnecessary applications running in the background to free up memory and processing power. In some cases, certain in-game graphics settings may be too demanding for your hardware, causing the game to crash when switching to full screen. Experiment with lowering the graphics settings to see if that resolves the issue; particularly textures and shadow quality.
