Remember to follow the Steps:
1. connect to the power to Video Adapter
2. connect to GOOVIS Young
3. connect to the HDMI cable and to your device with HDMI connector
If the HDMI output device cannot supply (enough) power to the GOOVIS Young (T2), you need to connect the DC 5V/2A power supply via the Adapter before connecting other devices, as shown in the following diagram. Otherwise, the GOOVIS T2 will not display normally.
