What is CRU and How to Download It?
If you are looking for a way to customize your monitor's resolutions and other capabilities, you might want to try Custom Resolution Utility (CRU). CRU is a free software that allows you to edit the Extended Display Identification Data (EDID) of your monitor, which defines its supported resolutions, refresh rates, timings, and other features. By using CRU, you can add, remove, or modify the resolutions that your monitor can display, as well as adjust other parameters such as FreeSync ranges, HDMI support, and pixel clock limits. In this article, we will explain what CRU is, what are its benefits and limitations, how to download and install it, how to use it for different purposes, and how to backup and encrypt your data with CRU products.
CRU: A Brief Introduction
What is CRU?
CRU stands for Custom Resolution Utility. It is a software developed by ToastyX that lets you edit the EDID of your monitor. EDID is a data structure that contains information about your monitor's capabilities, such as its manufacturer, model, serial number, supported resolutions, refresh rates, timings, color depth, and more. EDID is stored in a small memory chip inside your monitor and is read by your graphics card or integrated graphics when you connect your monitor to your computer. By editing the EDID, you can change how your monitor behaves and what resolutions it can display.

What are the benefits of using CRU?
Using CRU can have several benefits depending on your needs and preferences. Some of the common reasons why people use CRU are:
To add custom resolutions that are not available by default in your monitor or graphics driver settings. For example, you might want to add a higher resolution than your monitor's native resolution for better image quality or a lower resolution than your monitor's native resolution for better performance.
To remove unwanted resolutions that clutter your resolution list or cause compatibility issues. For example, you might want to remove interlaced resolutions that cause flickering or blurry images or remove resolutions that are not supported by your monitor or graphics card.
To edit FreeSync ranges that define the variable refresh rate (VRR) range of your monitor. For example, you might want to increase the lower limit of the FreeSync range to avoid stuttering or decrease the upper limit of the FreeSync range to avoid tearing.
To enable or disable HDMI support that determines whether your monitor can use HDMI features such as audio output, CEC control, or HDR. For example, you might want to enable HDMI support if your monitor has built-in speakers or disable HDMI support if you experience audio or video issues.
To adjust pixel clock limits that limit the maximum bandwidth of your video signal. For example, you might want to increase the pixel clock limit if you want to use higher resolutions or refresh rates than your monitor or cable can handle or decrease the pixel clock limit if you experience signal loss or corruption.
What are the requirements and limitations of CRU?
Before you use CRU, you should be aware of its requirements and limitations. Some of the important points are:
CRU works with both AMD/ATI and NVIDIA GPUs by creating EDID overrides directly in the registry without dealing with .inf files. However, it does not work with Intel GPUs or other types of GPUs.
CRU supports both LCD and OLED monitors, as well as some CRT monitors. However, it does not support monitors that use DisplayID instead of EDID, such as some 4K or 8K monitors.
CRU does not change the actual resolution or refresh rate of your monitor. It only adds or removes the options that are available in your graphics driver settings or games. To change the resolution or refresh rate, you still need to select the desired option from your graphics driver settings or games.
CRU does not guarantee that the custom resolutions you create will work with your monitor or graphics card. Some resolutions may cause black screens, flickering, artifacts, or other issues. You should always test the custom resolutions before applying them and use the reset-all.exe tool to restore the default EDID if you encounter any problems.
CRU requires administrator privileges to run and edit the registry. You should always run CRU as an administrator and backup your registry before making any changes.
