'''Commands and examples – verify before use:''' <br />
<syntaxhighlight lang="text"><br />
xrandr<br />
xinput<br />
xinput map-to-output <touch ID> <HDMI-ID><br />
sudo nano /etc/xdg/lxsession/LXDE-pi/autostart<br />
</syntaxhighlight><br />
<br />
== Notes and version constraints ==<br />
* Exact xinput/xrandr IDs depend on system configuration; the example uses ID 7 and HDMI-1.<br />
* To make touchscreen settings persistent, add the command to the autostart file and reboot the device.<br />
* The required 5 V/3 A power adapter is not included; verify availability before use.<br />
* Clarify version-specific differences between the UK and US models before deployment.<br />
