 Do not use any display which connects through HDMI.  The HDMI output is disabled by default in the Portsdown software for 2 reasons:  firstly, the HDMI output uses one of the clocks which is used by the DATV coding software and interferes with its operation; secondly, the Composite Video output is enabled for use with analog video transmitters, and use of this output disables the HDMI port.

 The Portsdown 2020 transmitter is also designed to be used with the Waveshare 3.5 inch Type A touchscreen which connects to the RPi using the GPIO connector. Although smaller than the 7 inch, it does permit composite video out to be available for use e.g. with FM transmitters. Many members have found that the first Waveshare expires during building of their Portsdown and after the 30 day Amazon guarantee. So it has been necessary to budget for a second screen.
