When using this module with a Raspberry Pi, we suggest editing config.txt to set "hd_safe=1" output for best results (otherwise, the Pi may not 'recognize' the HDMI-compatible display and revert to composite output). The easiest way to do that is to insert the programmed Pi SD card into your computer and look for the config.txt file that is in the root directory of the SD card, edit it, and save it.
