Please note that it is normal for the monitor screen to automatically turn on when the monitor is connected to a power source to recharge the battery. Rest assured, the monitor screen will automatically turn off and enter Sleep mode based on the sleep time you have set, ensuring that the monitor can be fully recharged in an efficient, timely manner.

However, if you prefer the monitor screen to remain off while the monitor is recharging, you can manually power off the monitor. This method will not impact the charging process.
