Thank you KenB, the monitor is a bit large to manhandle - especially at my age :).
So no it was not dropped - it is an Acer screen - that is flat. Not one of the bulkier ones from yester-year. I am unsure if it is an LCD thingy - hold on speccy might know. Yes, amidst the details.
It is as below but means little to me, it doesn't state the kind of monitor.

I have observed the splat and it is not growing at all. Perhaps it is something I'll have to live with.
