Sorry, I meant the image is wobbly...I think I am suffering the same effect as Luis above. I have emailed the US seller of my driver board and purchased another from China (again using Luis recommendation of EBay item 180979602491). There are delays because of Chinese New Year! I was very please that my screen from displayscreens works OK though! I just need a proper driver board.
I also used one of these for power: https://www.amazon.co.uk/gp/product/B018QF960A/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
However, the screen blanks out occasionally, I wonder if I it might be another symptom of the driver board though. So I will wait for the new board, and try to get a refund of my existing one.
