+fb
+--
+
+Configuration with graphics support in the form of a frame buffer driver for
the
+two HDMI outputs. This configuration is equipped with the ``fb`` frame buffer
+example, which displays some centered, colourful rectangles on the screen.
+
+.. warning::
+
+ This has only been tested with a display plugged into one HDMI interface at
a
+ time, not both connected. Whichever HDMI interface is plugged in will be
+ referred to as display 0 (i.e. ``/dev/fb0``).
+
+ The display **must** be plugged in to the Raspberry Pi 4B and powered on at
+ boot time. The BCM2711 VideoCore will refuse to allocate a frame buffer if
+ not, and registering ``/dev/fb0`` will fail.
+
+ The rendered image may exhibit gaps in the pixels. This is because rendering
+ directly to the framebuffer is too slow compared to the HDMI output in some
+ cases. If the image is rendered to a RAM buffer of the same size and then
+ ``memcpy``'d to the frame buffer, the image will be clear. I have not
+ modified the frame buffer example though since this is its own limitation.
+
+.. todo::
+
+ The frame-buffer driver always sets the physical and virtual display
+ resolution to 1080 x 1920 pixels with a depth of 32 bits per pixel. Other
+ options cannot yet be configured via Kconfig, nor is there any kind of
+ negotiation with the display to agree on some maximum quality options.
+
+lvgl
+----
+
+This configuration boots into an LVGL demonstration
+(:doc:`/applications/examples/lvgldemo/index`). It is using the 'widgets'
+variant of the demo. There is currently no way to interact with it since input
+devices aren't supported, but it's pretty! This configuration does nothing
else,
+but could be modified to boot into your own LVGL application.
+
+This configuration has the same warnings and limitations as those in the ``fb``
+configuration, with the exception of the pixel gaps. This is because LVGL uses
+the dual-buffer approach to rendering.
