To add other refresh rates, add the refresh rate at the native resolution. Laptop displays usually don't have scalers and can't display non-native resolutions without GPU scaling.Higher resolutions will only work if the monitor can handle them. Lower resolutions will be scaled up if GPU scaling is enabled in the graphics driver's control panel, but higher resolutions won't be scaled down by the GPU. CRU adds monitor resolutions, not scaled resolutions.The graphics driver will automatically add some common lower resolutions as scaled resolutions. All other resolutions can be removed if they are not needed. The first detailed resolution is considered the preferred or native resolution.More detailed resolutions can be added using extension blocks. Detailed resolutions are the preferred way to add custom resolutions.exe file and choose 'Install EDID' to install the EDID override on all matching displays. If you have an older Intel GPU, use the 'Export.' button and choose 'EXE file' for the file type to export a self-contained EDID override installer. Add custom resolutions, remove unwanted resolutions, edit FreeSync ranges, and more.
