1. Go to Settings -> System and uncheck the Enable checkbox HDCP
2. Your connections must not be directly on the ps4 but have to go through in other media, for my part I passed by my home cinema
3. the Board ps4 always looking for you to 1080p as it is set in the Automatic setting displays and screen I recommend you because ecant 720p VGA not above supporting and voila it works!
