Screen Issues

Hey guys,

I built my raspberry3, Hifiberry Dac+ and Volumio system a few weeks ago. I´m very happy with it the sound is great.
Today my 5" touchscreen arrived. Unfortunatly it doesn´t work at all.
I tried it with the gpio pins without the Hifiberry and the original HDMI adapter. with a HDMI cable and extra power supply and also connected with an USB cable to the RP3.
All I get is a grey picture with moving lines.
The screen works with my PC an PS3 so it must be an issue with the HDMI signal of the pie. Other screens also don´t work on it.

Is there an driver wich needs to be installed, I couldn´t find any.

Thank you for your help!
