I bought a Raspberry Pi model B 3. Also I bought a 7 inch HDMI touch screen display for it.
If I connect the 7" HDMI touch screen's HDMI cable to my mac, the screen works fine.
If I connect the Raspberry pi with an HDMI monitor, it displays perfectly.
When I connect the HDMI screen with Raspberry pi. It does not show anything on screen. It just shows a white ribbon on the screen.
My Raspberry pi uses, Raspbian Jessie OS.
Above shows I need to change some configuration in Raspberry Pi for displaying in small screen. Kindly help me for the same.
