3.2 Software Setup

Supports Raspberry Pi OS, Ubuntu, Kali, and Retropie systems.

1. Connect the TF card to the PC.

2. Download and install the Raspberry Pi Imager from the Raspberry Pi official website.

3. Launch the imager, select the TF card you wish to write the image to (Note: It's best to remove any other USB storage devices to prevent accidental erasure of data).

4. Preconfigure the system settings by holding CTRL+SHIFT+X (or clicking the small gear icon in the bottom-right corner) and then save.

5. Click the write button to write the data to the TF card.

6. After writing is complete, open the /boot/firmware/ directory and append the following lines to the end of the config.txt file, then save and exit:

   hdmi_force_hotplug=1
   config_hdmi_boost=10
   hdmi_group=2
   hdmi_mode=87
   hdmi_cvt 1024 600 60 6 0 0 0
   

    

7. Insert the TF card into the Raspberry Pi, power it up, and wait a few seconds for the display to initialize properly.

4. Using with Windows PC

4.1 Software Setting

Supports Windows 11 / 10 / 8.1 / 8 / 7 on PC.

1. Connect the LCD's touch interface to the USB port of the PC. After a moment, Windows will automatically recognize the touch functionality.
2. Connect the LCD's HDMI interface to the HDMI port of the PC. After a few seconds, you should see the LCD display normally.

Note 1: When the computer is connected to multiple displays, the cursor can only be controlled on the main display using this LCD, so it is recommended to set the LCD as the primary display.

Note 2: Some PC USB ports may provide insufficient power due to aging; in this case, you can use a USB port on the back of the PC or connect an external 5V 2A power adapter.
