Requirements
------------

In order to follow this guide you will need an HDMI cable as well as an HDMI capable display such as a monitor.

* HDMI cable
* HDMI monitor

.. note:: Be sure that you are not using a headless BSP image as this does not support the HDMI interface.

------------------------

* Power off and remove the power supply from the development kit.

  .. code-block:: none
    :caption: Target (Linux)

     poweroff

* Connect the HDMI display to X45 and to the HDMI monitor.

* Power on the development kit. As the board is booting, 4x Tux the penguins should appear, followed by a PHYTEC logo with a loading bar and finally a "Multitouch" qtdemo should show on the screen.

.. note:: There is a known issue with qt5demo having a distorted image with missing pixcels.
