HDMI
Pigeon computers are equipped with a full-size HDMI (Type-A) port for direct connection using a standard HDMI cable.
The setup for HDMI connections is demonstrated on the raspberry.com website.
Useful commands
The kmsprint tool allows you to list the display modes supported by monitors connected to the Pigeon device. Use kmsprint to view details about the connected monitors, and kmsprint -m to display a list of all supported display modes for each monitor. The source code for the kmsprint utility is available on Github.
$ kmsprint
$ kmsprint -m
Legacy systems only (tvservice)
The tvservice utility is deprecated and not supported on recent distributions using KMS. It is available only on older systems based on the legacy Raspberry Pi video stack.
For modern systems, use KMS-based tools instead. The following commands apply only to legacy distributions.
