Custom Resolution Utility - CRU

Custom Resolution Utility - CRU allows custom resolutions to be defined for both AMD/ATI and NVIDIA GPUs by creating EDID overrides directly in the registry without dealing with .inf files.



It can now read extension blocks from connected monitors with AMD/ATI and NVIDIA. Workarounds are no longer required for NVIDIA.

It will automatically add a blank extension block in the registry and .inf files if necessary to work around NVIDIA driver issues. Custom Resolution Utility - CRU adds monitor resolutions, not scaled resolutions

Lower resolutions will be scaled up if GPU scaling is enabled, but higher resolutions won't be scaled down by the GPU. Higher resolutions will only work if the monitor can handle them.

The program is a lightweight and advanced tool developed by ToastyX. It enables users to create and customize resolutions and refresh rates for their displays beyond the standard options provided by the operating system.

CRU is primarily used to add custom resolutions, tweak timing parameters, and fine-tune the display settings to achieve optimal performance and visual quality.

Getting started

• Run CRU.exe.
• Choose a monitor from the drop-down list.
• "(active)" means the monitor is connected and recognized by the graphics driver.
• "*" means changes were made and an override was saved in the registry.
• Edit the configuration as desired. Please read the sections below for more information.
• Repeat steps 2-3 for other monitors if required.
• The "Copy" and "Paste" buttons at the top can be used to copy the resolutions, extension blocks, and range limits if included. It will not copy the name or serial number, but it will copy the inclusion of these items using the monitor's own information. Import follows the same logic unless "Import complete EDID" is selected.
• Click "OK" to save the changes.
• Run restart.exe to restart the graphics driver.
• If the display does not return after 15 seconds, press F8 for recovery mode. This will temporarily unload all the EDID overrides without deleting them. Restart the driver again to reload any changes.
• Set the resolution in the Windows display settings. To set the refresh rate:
• Windows 11/10: right-click on the desktop > Display settings > Advanced display settings > Display adapter properties > Monitor tab
• Windows Vista/7/8/8.1: right-click on the desktop > Screen resolution > Advanced settings > Monitor tab

To reset a display back to the default configuration, use the "Delete" button at the top to delete the override from the registry and reboot. To reset all displays, run reset-all.exe, and reboot. This can be done in safe mode if necessary.

Requirements

• OS: Windows 7, 8, 10 or 11
• AMD/ATI or NVIDIA GPU with the appropriate driver installed (Microsoft Basic Display Adapter driver does not support EDID overrides)
• Some Intel GPUs and laptops with switchable graphics are supported with one of these drivers:
• 6th/7th generation (Skylake/Kaby Lake): Intel Graphics Driver for Windows [15.45]
• 4th/5th generation (Haswell/Broadwell): Intel Graphics Driver for Windows [15.40]
• 4th generation (Haswell) for Windows 7/8.1: Intel Graphics Driver for Windows 7/8.1 [15.36]

Standard resolutions

• Standard resolutions are mostly useful for CRT monitors and for adding lower resolutions with LCD monitors. Do not add the native resolution as a standard resolution.
• AMD/ATI only supports the resolutions in the drop-down list. Other resolutions will be ignored by the driver. These will be listed in gray.
• NVIDIA does not support more than 8 standard resolutions.
• Standard resolutions are limited to 60-123 Hz. Use detailed resolutions to add other refresh rates.

Main Features

Custom Resolution Creation: It allows users to create custom resolutions and refresh rates that are not typically supported by default settings. This feature is particularly useful for users who want to optimize their gaming experience or work with specialized applications.

Detailed Timing Parameters: With the tool, you can precisely control various timing parameters such as horizontal and vertical sync, front and back porch, and pixel clock. This level of customization ensures compatibility and stability while pushing the boundaries of display capabilities.

EDID Management: The software enables users to modify the Extended Display Identification Data (EDID), which contains information about the monitor's capabilities. By editing the EDID, you can bypass certain limitations and unlock additional resolution and refresh rate options.

Backup and Restore Profiles: It allows you to save and load custom profiles, making it easy to switch between different display configurations. This feature is especially beneficial for multi-monitor setups or users who frequently switch between different usage scenarios.

Hotkey Support: The software provides hotkey support for quickly switching between different resolutions and refresh rates, making it convenient to toggle display settings on the fly.

User Interface

It features a straightforward and minimalistic user interface that focuses on functionality rather than aesthetics. The main window provides an organized layout with tabs for managing display profiles, creating custom resolutions, and editing EDID.



While the interface may appear slightly technical for novice users, it offers extensive documentation and tooltips to guide users through the various options and settings.

Installation and Setup

Installing CRU is a straightforward process. After downloading the software from the official website or FileHorse, the installation wizard guides you through the necessary steps, ensuring a hassle-free setup.

Once installed, it integrates with the system seamlessly and is ready for use.

FAQ
