Attention:
1. If the Raspberry Pi is connected without modifying the resolution, and has produced display abnormalities such as splash screen or burned screen, just follow the above operation to modify the config file and then re-power the screen to observe, if found that there are residual shadows or flickering problems, the screen will be powered off and left to rest for more than half an hour to recover.
2. If you are using Pi4 or higher, the screen HDMI cable needs to be connected to the HDMI0 interface of the Raspberry Pi (near the power connector), otherwise the screen will appear half flashing horizontal lines.
