The Custom Resolution Utility (CRU) is a powerful software tool for Windows operating systems that allows users to add custom resolutions and refresh rates to their monitor’s settings. This utility is precious for those looking to optimize their display configurations beyond the standard options provided by their graphics driver. Whether you’re a gamer seeking the perfect refresh rate or a professional needing specific resolution settings for detailed work, CRU offers a versatile solution.

CRU operates by modifying the Extended Display Identification Data (EDID), a set of information embedded in monitors that communicates supported display modes to the graphics card. By altering this data, CRU enables the addition of resolutions and refresh rates that may not be natively supported by the monitor’s firmware or the graphics driver. This capability is handy for users who wish to unlock higher refresh rates for smoother gaming experiences or create custom resolutions for unique display setups.

One of the standout features of CRU is its ability to add both standard and detailed resolutions. Standard resolutions are common modes that most monitors support, while detailed resolutions allow for more precise control over timing parameters, ensuring compatibility and optimal performance. The utility also provides options to backup and restore EDID settings, giving users a safety net and the confidence to experiment with different configurations.

Features of the Custom Resolution Utility

Custom Resolutions and Refresh Rates

CRU allows users to create custom display resolutions and refresh rates beyond default. This benefits gamers and professionals who require specific settings for better visual quality and performance.

Detailed vs. Standard Resolutions

• Standard Resolutions: Commonly supported resolutions that are typically straightforward to configure.
• Detailed Resolutions: Allow for precise control over timing and parameters, optimizing compatibility and performance for specific use cases.

EDID Management

CRU modifies the Extended Display Identification Data (EDID), which contains information about the monitor’s capabilities. This enables users to override default settings, add new resolutions, and back up current configurations for safety.

Compatibility with Various Graphics Cards

CRU supports most AMD and NVIDIA graphics cards, making it a versatile tool for many users. This broad compatibility ensures that many can benefit from custom resolutions and refresh rates, enhancing their overall display experience.

How It Works

Custom Resolution Utility (CRU) allows users to modify their monitors’ EDID (Extended Display Identification Data). EDID is a metadata format that contains information about a monitor’s capabilities, such as its native resolution, refresh rate, and color depth. Users can add, modify, or remove resolutions and refresh rates using CRU to optimize display settings.

Basic Operation of CRU

1. Launch CRU:
   • After downloading and extracting CRU, run CRU.exe.
   • The main interface displays your monitor’s existing resolutions and detailed timings.
2. Select a Monitor:
   • Choose the monitor you want to modify from the dropdown list at the top of the CRU window.

Adding and Modifying Resolutions

1. Adding a Resolution:
   • Click “Add” under the “Detailed resolutions” section.
   • Enter the desired resolution (e.g., width and height) and refresh rate.
   • Click “OK” to save the new resolution.
2. Modifying a Resolution:
   • Select the resolution you want to change from the list.
   • Click “Edit” to adjust the resolution settings.
   • Make the necessary changes and click “OK” to save.
3. Removing a Resolution:
   • Select the resolution you want to remove.
   • Click “Delete” and confirm the removal.

Adjusting Refresh Rates and Other Settings

1. Adjusting Refresh Rates:
   • When adding or editing a resolution, specify the desired refresh rate.
   • Ensure the monitor and the graphics card support the refresh rate to avoid display issues.
2. Detailed Timings:
   • For advanced users, CRU provides options to adjust detailed timings, such as:
     • Front Porch and Back Porch: Define the non-display intervals between the active video signal and the sync pulse.
     • Sync Width: The duration of the sync pulse.
     • Pixel Clock: The frequency at which pixels are transmitted.
   • These settings can fine-tune the display performance but should be adjusted carefully to prevent errors.
3. Extension Blocks:
   • CRU allows adding or removing EDID extension blocks to manage audio and video settings.
   • This is useful for turning features like HDMI audio on or off.

Applying Changes

1. Save and Apply:
   • After making the desired changes, click “OK” in the main CRU window.
   • Restart your computer for the changes to take effect.
2. Resetting to Default:
   • If issues arise, use the reset-all.exe utility included with CRU to revert to the default settings.

Tips

• Always back up current settings before making changes.
