How To Get Custom Resolution / Stretch Res for Fortnite, Apex Legends, Halo, and any other game

This post delves into the complexities of using Custom Resolution Utility (CRU) for EDID overrides on Windows. It’s designed for users with AMD/ATI, NVIDIA, or certain Intel GPUs who seek custom resolutions or refresh rates for an optimized display experience.

WARNING: Failure to back up your current settings and not being able to use safe mode for recovery if needed will result in major headaches!

Requirements

Operating System: Windows Vista or later. Windows XP is incompatible with EDID overrides.
Graphics Processing Unit (GPU): AMD or NVIDIA GPU with the latest drivers.
Safe Mode Knowledge: Understanding how to access safe mode for recovery purposes is crucial.

Initial Setup with CRU

  1. Launching CRU: Run CRU.exe. Admin rights might be required to modify registry settings.
  2. Display Selection: Choose your display from the list. Active displays are marked and any changes will be saved in the registry.
  3. Editing Configurations: Customization options are vast. Consider reading detailed documentation for each setting.
  4. Cloning Settings: Use the copy-paste feature to apply settings to multiple displays.
  5. Saving and Restarting: After saving changes, restart the graphics driver. If issues arise, recovery steps are provided.

Detailed Resolutions

Introduction to Detailed Resolutions

Purpose: Detailed resolutions in CRU are used to fine-tune the display properties beyond the standard presets offered by your GPU or monitor. This feature is crucial for professionals in graphic design, gaming, or any field where precise display characteristics are needed.
Native Resolution: The first detailed resolution is typically set as the native or preferred resolution of the monitor. It’s important to accurately configure this to ensure optimal display quality.
Adding Custom Resolutions

Accessing the Feature: In CRU, under the ‘Detailed resolutions’ tab, you can add new resolutions.
Resolution Limits: Be aware of the maximum resolution and refresh rate supported by your monitor and GPU. Exceeding these could lead to display issues or hardware damage.


Refresh Rate: Increasing the refresh rate can result in smoother visuals, which is particularly beneficial for gaming. However, ensure your monitor can handle the higher rate.

Understanding Resolution and Refresh Rate

Impact on Performance: Higher resolutions and refresh rates can be more demanding on your GPU. Monitor your system’s performance and adjust accordingly.
Compatibility with Content: Some content, especially video, may be optimized for specific resolutions and refresh rates. Adjust your settings to match for the best viewing experience.

GPU Scaling

CRU adds monitor resolutions, not scaled resolutions. Enabling GPU scaling in the graphics driver’s control panel can allow lower resolutions to scale up to the native resolution. However, note that higher resolutions won’t be scaled down by the GPU and will only work if the monitor can handle them.

Limitations and Warnings

Maximum Limits: EDID detailed resolutions are limited to 4095×4095 and 655.35 MHz pixel clock. Exceeding these values could result in improper display functionality.
Invalid Values: If a value turns red in CRU, it indicates that it’s either invalid or out of the acceptable limits. Double-check your settings in such cases.

Setting Timing Parameters

Manual Timing: Allows for manual input of timing parameters. This is recommended for advanced users who understand monitor timings.
Automatic Options: CRU offers various automatic timing options, such as Automatic PC, HDTV, and CRT, which set timings based on common standards. Choose the one that matches your monitor type and desired resolution.
Exact Timings: For achieving exact integer refresh rates. This is particularly useful for users who are sensitive to refresh rate variations.

Testing and Validation

After configuring a new resolution, test it thoroughly. Look for issues like screen flickering, color distortion, or text clarity problems.
It’s advisable to make changes incrementally, especially when experimenting with higher resolutions or refresh rates, to easily identify the cause of any issues.
