Technical overview

  • Resolution: 480 × 800 (portrait by default); orientation can be changed via software.
  • Connections: an “Only Power” USB port for power and an HDMI port for the video signal.
  • Compatibility: supports Raspberry Pi OS, Ubuntu, Kali, and RetroPie; on Windows it works with versions 7 through 11.
  • When using a PC, connect the USB power port first, then the HDMI port; a PC restart may be required.
  • For Raspberry Pi use, set the HDMI group and mode in the config.txt file on the SD card before inserting it into the Pi.
  • Brightness is adjustable via the side buttons, which reduces power consumption.
  • Updating the software version under Bullseye is recommended before first boot; other systems can skip this step.
  • Rotation angles are configured via xrandr or display_rotate depending on whether a KMS/FKMS driver is loaded.

Commands and examples – verify before use:  

hdmi_group=2
hdmi_mode=87
hdmi_timings=480 0 50 20 50 800 0 19 20 20 0 0 0 60 0 38000000 6
sudo apt-get update
sudo apt-get full-upgrade
xrandr -o 1
display_rotate=3
disable_splash=1
fbcon=rotate:3 video=HDMI-A-1:640x480M@60,rotate=90

Notes and version constraints

  • The exact hdmi_timings values are version-sensitive and must be verified per system.
  • Whether a KMS or FKMS driver is loaded determines which rotation command to use; this must be confirmed per system.
  • The Linux console command uses 640×480 as the video resolution while the native display resolution is 480×800 – this discrepancy should be manually confirmed.
  • Touch-related instructions in the source refer to capacitive touch screens; this model is listed as no-touch, so those steps do not apply here.
  • No information on price, stock, certifications, or warranty is present in the source material.
