Technical overview

  • Resolution: 800 × 480 pixels; resistive touch input
  • Interfaces: HDMI for video output, USB for the touch function
  • Supported PC systems: Windows 7/8/8.1/10/11
  • Supported Raspberry Pi systems: Raspberry Pi OS, Ubuntu, Kali, RetroPie
  • When used with Raspberry Pi, the resolution must be set manually in config.txt, otherwise the display may be abnormal
  • Power consumption at 5 V input: about 385 mA with backlight on, about 195 mA with backlight off
  • Backlight is controlled by a switch on the back of the LCD
  • Screen refresh rate: 60 Hz

Commands and examples – verify before use:  

hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
hdmi_drive=1
disable_splash=1
sudo apt-get install xinput-calibrator
sudo apt-get install xserver-xorg-input-evdev
sudo cp -rf /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf
sudo reboot

Notes and version constraints

  • The exact hdmi_cvt line depends on firmware version; verify that the parameters match your Pi firmware before saving.
  • Testing hardware modifications (e.g., brightness adjustment via the resistor) risks damaging the LCD; do not attempt without experience.
  • If the screen stays blank during calibration under Windows, press Enter to switch input to the touchscreen.
  • For thin red lines at the screen edge: add hdmi_drive=1 to config.txt.
  • The long-press emulation (evdev-rce) requires a specific test environment (raspios-bullseye-armhf 32-bit); compatibility with newer systems must be checked individually.
