💡 Screen Dimensions Override for Desktop PCs & Laptops

The Xbox Full Screen Experience is designed for handheld-sized screens. If your device is not a handheld, a screen dimensions override is required. This tool offers two distinct methods, and now automatically guides you to the appropriate choice based on your device type.

Task Scheduler Mode: PhysPanelCS (Recommended)

This is the default and recommended method. It is easy to use, requires no additional manual setup, and provides high reliability for all devices, including desktops and laptops.

Driver Mode: PhysPanelDrv (Alternative)

This is an alternative advanced mode that uses a custom kernel driver to apply the override at the earliest stage of system boot. This method is an option for users who may still encounter issues with the default PhysPanelCS mode, but it requires disabling Secure Boot and enabling Test Signing (see prerequisites below).

Which Mode Should You Use?

• For Desktops & Laptops: Start with PhysPanelCS. This is the recommended, safest, and most reliable method for most users. If you experience any issues with this default mode, PhysPanelDrv is available as a fallback alternative (requires the prerequisites listed below).
• For Handheld Devices: Your device does not require PhysPanelCS or PhysPanelDrv. The mode selection UI will be automatically disabled.

Prerequisites for PhysPanelDrv Mode (Alternative)

⚠️ Important: These steps are only necessary for desktop and laptop users who choose to use the alternative PhysPanelDrv mode.

Installing this test-signed driver requires you to manually disable Secure Boot and enable Windows Test Signing Mode.

Step 1: Enter BIOS/UEFI Settings

1. Restart your computer and press the designated key during boot (usually Del, F2, F10, or Esc) to enter the BIOS/UEFI setup.
2. Find and disable the Secure Boot option.
3. Save your changes and exit.

Step 2: Enable Test Signing in Windows

1. Once your computer has restarted into Windows, open Terminal (PowerShell or Command Prompt) as an administrator.
2. Enter the following command and press Enter:

   bcdedit /set testsigning on
   

3. Restart your computer one more time to apply the change.

After completing these steps, you can select PhysPanelDrv in the tool.

🚀 Quick Start

This process consists of preparing your system with the tool, updating apps, and finally enabling the feature in Windows Settings.

1. Prepare Your System

1. Download the latest .msi package from the Releases Page.
2. Run the installer (administrator privileges required).
3. Launch the tool from the desktop shortcut. If using a desktop PC or laptop, the tool will automatically select the recommended PhysPanelCS mode.

   Note: If you are a desktop or laptop user and wish to use the alternative PhysPanelDrv mode, you can select it manually. Ensure you have completed the prerequisites listed above first.

4. Click the “Enable Xbox Full Screen Experience” button.
5. Accept the system restart confirmation prompt.
6. The tool will verify your environment. If no physical touch screen is detected, you will be prompted to select "Yes" to enable touch simulation. This ensures you can use your controller to operate the on-screen virtual keyboard (Gamepad Keyboard) properly. Your PC will restart automatically to apply all changes.

2. Update Core Apps

1. After restarting, launch the tool again.
2. Click the "Check MS Store for Xbox Updates" button (or manually open Microsoft Store > Downloads or Library).
3. Click "Check for updates" within the Store to refresh all apps. Make sure Xbox and Xbox Game Bar are fully updated.

   🔄 Tip: You may need to run "Check for updates" twice to ensure everything is fully installed.

3. Activate Full Screen Experience

1. Click the "Open Full Screen Experience Settings" button in the tool (or navigate to Start → Settings → Gaming → Full screen experience).
2. Set "Choose Home app" to Xbox.
   • If this option is missing, return to "Update Core Apps" and ensure the apps are fully updated.
3. Enable "Enter full screen experience on startup".

How to Revert

1. Run the tool again and click “Disable & Restore”.
2. Restart your PC to complete the process.
