What functions can't be adjusted when Xiaomi Gaming Monitor G27i Professional Mode is turned on?

When HDR is turned on, Picture Mode and Gaming Mode are displayed in grey, which means that these two modes cannot be adjusted.
Note: If you choose different professional modes, some functions can be adjusted, depending on the scene. Depending on individual usage habits and scenarios, personalised settings will be provided. Enable FreeSync, turn off HDR, and set the image mode and game mode status.
