Lenovo laptops use LCD monitors correctly. Even monitors with relatively good performance should not display the same static picture for a long time. Therefore, in addition to the performance of the monitor itself, you must also develop good usage habits:

　1. Turn off the monitor when not in use.

2. Make sure the operating system is in power saving mode and set the time to 10-15 minutes so that the LCD can take a break when the monitor is not used for 15 minutes.

3. You can enable the screen saver to prevent the monitor from displaying the same still image for a long time.

4. You can change the desktop background image frequently.

5. If you find that there is an afterimage on the monitor, you can try turning off the monitor for a few days to see if it can recover.
