4. Can I use the screen without installing drivers?
No. This screen uses an SPI interface and requires a dedicated driver to function.
5. Why does my screen stay black or white after powering on?
Make sure the correct driver is installed. Ensure your operating system is compatible. Check that the screen is properly connected to the GPIO pins.
6. What if I get git not found or network errors during installation?
Make sure your Raspberry Pi is connected to the internet. If Git is not installed, run: sudo apt update, sudo apt install git
Then retry the installation.
7. Why is the screen orientation incorrect?
You can fix the screen and touch orientation by running:
cd LCD-show/ (adjust the path depending on your OS), sudo ./rotate.sh 90

If the HDMI monitor remains connected, it may show a black screen or no display output.
9. Why does the fan keep spinning?
Can it be controlled by software?
The fan header provides constant 5V power and does not support software control. The fan will always spin when connected.
