I ordered this and tried using it with 2 different Raspberry Pi's with the same result each time - a white screen with a rotating scanline.

Both RPi's work as expected when plugging into a TV using the same HDMI cable used in testing, so I assume this must be some issue with the display itself.

Did you configure the Pi for the correct screen resolution?
