When Huawei's smart screen is turned on, the default screen will enter the automatic screen off state after 5 minutes of no operation. If you need to change the automatic screen closing time, you can click on the top right corner of the smart screen home page and select General > Automatic Screen Closing to set the automatic screen closing time.

Two automatic screen blanking rules are realized in the following ways:

● When there is no operation within 5 minutes after startup, the smart screen will automatically close. This rule has the highest priority and always takes effect.

● When there is an operation within 5 minutes of starting, the rule of closing the screen without operation will be invalid after 5 minutes of starting, and the smart screen will continue to process according to the automatic closing time you set.

For example, if you set the automatic screen closing time to 0.5 hours, you will not operate after the second minute of power on. At this time, it will be invalid to turn off the screen after 5 minutes of power-on. If you set the automatic screen closing time to 0.5 hours, the smart screen will be closed at the 32nd minute after the power is turned on.

Note: When the smart screen is turned off and turned on again, the default signal source will automatically play because it enters the default signal source function, and the screen will not automatically turn off (stand by).
