== Summary ==<br />
Concise technical guide for the Waveshare 5-inch DSI display (model 50H-800480-IPS). It covers hardware connection to a Raspberry Pi, configuration via config.txt and cmdline.txt, and adjustment of brightness, rotation, and touch.<br />

<br />
== Technical overview ==<br />
* Resolution 800×480 pixels, IPS panel with 50% NTSC color gamut, brightness about 300 cd/m², contrast 1000:1, refresh rate up to 60 Hz.<br />
* Connection is made through the Raspberry Pi DSI port using an FFC cable; the gold finger on the display-side connector must face upward.<br />
* Compatible with Pi 2B, B+, A+, 3B/3B+/3A+ and Pi 4B; some CM3/CM3+/CM4 boards additionally require a 15 cm DSI cable.<br />
* For system installation, use the official Raspberry Pi OS, Ubuntu, Kali or Retropie image flashed with Raspberry Pi Imager, then add dtoverlay=vc4-kms-v3d and dtoverlay=vc4-kms-dsi-7inch to config.txt.<br />
* Brightness can be adjusted graphically via screen settings, via a Waveshare brightness application, or via terminal commands writing to /sys/class/backlight/*/brightness.<br />
* Display rotation can be set depending on OS version via the graphical interface, entries in /boot/cmdline.txt such as video=DSI-1:800x480M@60,rotate=90, or display_rotate in config.txt.<br />
* Touch rotation is configured synchronously with the display on newer systems; on older systems it must be adjusted separately via udev rules or X11 configuration files.<br />

'''Commands and examples – verify before use:''' <br />
<syntaxhighlight lang="text"><br />
dtoverlay=vc4-kms-v3d<br />
dtoverlay=vc4-kms-dsi-7inch<br />
dtoverlay=vc4-kms-dsi-7inch,dsi0<br />
echo 100 | sudo tee /sys/class/backlight/*/brightness<br />
video=DSI-1:800x480M@60,rotate=90<br />
display_rotate=1<br />
</syntaxhighlight><br />
<br />
== Notes and version constraints ==<br />
* Compatibility with certain CM boards depends on the exact board type; verify before installation whether an external 15 cm DSI cable is required.<br />
* Rotation and touch steps differ by operating-system version (Trixie, Bookworm, Bullseye/Buster, Stretch/Jessie); follow only the instructions matching your installed system.<br />
* Older DSI LCD revisions (e.g., Rev2.1) may cause issues with Pi 5; seek manufacturer confirmation if unsure.<br />
* All changes to config.txt, cmdline.txt or system files require a reboot to take effect.<br />
* If uncertain about version-sensitive steps or missing context, have a human confirm the procedure.<br />
