The following explains how to fix the issue where the refresh rate (Hz) setting in CCBoot does not work when using SmartShell.

  1. Smartshell blocks CCBoot script on startup about the refresh rate
  2. Try adding the following program to auto-start:
  3. Go to Settings > Shell > Autostart and add:
    C:\Windows\System\SmartShell\rresolution.exe
  4. This will ensure the refresh-rate tool runs automatically.
  5. Set the application to autostart through the admin panel by selecting the program located in the Smartshell’s installation folder.
