Display setup on RPi4¶

This assumes that you'll be using the Raspberry Pi 7'' display. Installation can be found at Rpi Display page.

If booting over the network, the dtb should already contain the ft5406 dtb, while booting over sd-card the following show be in the /boot/config.txt file:

dtoverlay=rpi-ft5406-overlay

Once the board boots up, you should get a rainbow like effect and afterwards booting up would display debug scrolling over. You'll need to adjust the orientation as the 800x480 is in portrait. Edit /etc/xdg/weston/weston.ini and add a new output entry, like the following:

[output]
name=DSI-1
transform=90

Note that for the Qt platform, the homescreen application, together with the other demo applications, is tailored specifically for a 1080p display and it will display incorrectly on such a smaller display.
