Custom Resolution Utility

Custom Resolution Utility (CRU) is a free, portable Windows utility for creating custom display resolutions and refresh rates by editing Extended Display Identification Data (EDID). It shows how your monitor's resolutions are configured and lets you add new resolutions, remove unwanted ones, and adjust FreeSync and refresh-rate settings — all without installation. CRU unlocks hidden resolutions that your monitor or GPU may support but that don't appear in standard Windows settings, making it ideal for high-definition and ultrawide displays. Gamers and creative professionals can fine-tune refresh rates to minimize screen tearing and stuttering, while color depth and range adjustments improve color accuracy. Multi-monitor support lets you assign unique resolutions and refresh rates per screen. The tool manages HDMI behavior (including HDMI-as-single-link-DVI defaults and TMDS clock limits), accounts for DisplayPort-to-HDMI adapter constraints, and respects graphics-card-dependent bandwidth limits. CRU works with AMD/ATI, NVIDIA, and Intel graphics cards on Windows Vista through Windows 11. Because it's portable, you can run CRU.exe directly from any storage device - no setup, no fees. After applying changes, restart.exe reloads the graphics driver so new resolutions take effect. Free to download from the official site.
