2) Some of PC cannot support HDMI screen Hot Plug. In this case, restart the PC can solve.

Working with Raspberry Pi

This LCD can support Raspberry Pi OS / Ubuntu / Kali / Retropie systems.

Please download the latest version of the image on the Raspberry Pi official website.

1) Download the compressed file to the PC, and unzip it to get the .img file.
2) Connect the TF card to the PC, use SDFormatter software to format the TF card.
3) Open the Win32DiskImager software, select the system image downloaded in step 1, and click ‘Write’ to write the system image.
4) After the image has finished writing, open the config.txt file in the root directory of the TF card, add the following code at the end of config.txt, then save and quit the TF card safely.
hdmi_group=2 
hdmi_mode=87 
hdmi_timings=1280 0 160 32 48 720 0 10 10 12 0 0 0 60 0 77000000 3
5) Insert the TF card into the Raspberry Pi
6) Connect the 5V power supply to the Power port of the LCD, and you can see that the LCD backlight is lit normally.
7) Connect the Touch interface of the LCD to the USB port of Raspberry Pi.
8) Connect the HDMI interface of the LCD to the HDMI port of Raspberry Pi and then power on the Raspberry Pi, it can display normally after waiting for about a few seconds.

Anti-Piracy

Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They're usually some poor copies of our early hardware revisions, and comes with none support service.

To avoid becoming a victim of pirated products, please pay attention to the following features when purchasing:
