In any event - To be perfectly clear to anyone who is looking to purchase this monitor, please don't let my experiences negatively influence your decision. As CRE4MPIE has said, VAs are the way they are, and it's entirely possible I am simply not used to them. My various efforts at interrogating the problem have led to me expressing my frustration, and I recognise and apologise for the fact that this is not helpful to people trying to make a decision.
What I am doing on my end, to finalise the whole thing will be to plug it into a friend's computer this week, just to eliminate any of the issues being something iffy on my end and based on that, I will make a decision on how to proceed.
I really had hoped to help - not hinder - people looking at buying this monitor, and if there's anything I can do to ameliorate the concerns I may have caused, please feel free to request it.
@CRE4MPIE Sorry if I was a bit snippy earlier; I am happy to chat about the monitor, I was just taken aback at your perception of my attitude, but I've given it some thought and I realise I was probably not helping by being anything that entirely objective about the whole situation.
