Fixed the monitor issue I was having - hoorah - and realised I DON'T have a SP 4, which is what I thought I'd ordered, but a Surface Book (took putting it side-by-side with a colleague's SP4 to realise) #highlyembarassed #notREALLYditzyfemale
So, can I update my reflect my correct device (and hide my stupidity)? If so how? Or am I being ditzy again...
Anyway, as for the monitor, a Samsung S22E650 works perfectly, in comparison to the DELL 2016 which definitely didn't. I also found out that leads cause more problems than the monitors!!
So thanks for the support - just knowing it's there helped!
