== Technical overview ==
* Panel: 4.3-inch IPS/QLED, native resolution 800 × 480 pixels
* Viewing angle: 160°
* Color gamut: 50 % NTSC (IPS) or 78 % NTSC (QLED)
* Brightness: 300 cd/m²; contrast ratio 1200:1; color depth 16.7 M colors
* Refresh rate up to 60 Hz
* Driven via the Raspberry Pi DSI port; no additional drivers required for the listed operating systems
* Housing dimensions: 105.42 × 67.07 × 2.90 mm (display); touch variants approx. 112.40 × 75.10 × 5.00 mm or 106.10 × 67.80 × 5.20 mm
* Connection via FFC cable to the DSI port; gold finger on the display side faces upward

== Notes and version constraints ==
* The compatibility list covers only the Raspberry Pi models named in the source; other boards are unconfirmed
* When using the DSI0 interface (Pi5/CM4 only), append “dsi0” to the dtoverlay entry
* Older revisions (e.g., Rev2.1) may cause power-detection issues on Pi5; removing certain capacitors may be required
* The GUI steps described apply mainly to Trixie/Bookworm; older systems such as Bullseye/Buster need manual touch rotation settings
* Installing the Waveshare Brightness tool requires internet access for the download
* The commands and file paths provided should be verified against the specific system before use
