== 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.

== 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.
