This effect could be caused by an insufficient DC power supply.
Please try a 6v or 7v, 2amp power supply for this HDMI display.

Best Regards,

Okay that worked, I also turned up the hdmi output power within the config.txt

So next question, how do I get the touch screen working on my Raspberry Pi? Is there some software i need to install or settings to turn on? The manual seems to skip over the touchscreen function.

The touch screen is a plug and play USB-HID device which is connected to through the Mini-USB port CN2.
No external drivers are required for Linux or Windows.
