This time I purchased:
https://www.amazon.co.uk/dp/B09K79LX...fed_asin_title
It looked compatible with DisplayLink.
However, once installed and all driver the best I can get is the screens to show:
Universal Graphic Adapter...
Then they go black again. The DL item in the icon bar is useless,
I don know what I am doing wrong,
PLEASE don't tell me its a hardware issue AGAIN
