Yeah, I don't think that was funny either.
It was an inappropriate response.
I note thunderflies, midges, noseeums, gnats, or whatever you want to call them can be a real nuisance, especially when they become trapped and die in such visible, but distracting places. This is actually the 3rd time in a month I have seen this same complaint from UK users, and sadly, I only have the following to offer - and it has not been too successful.
You can try to disconnect the monitor, turn it upside down and shake it in the hopes the bug will fall behind the bezel (the covering over the edges of the screen) and out of sight. You can try blasting compressed air in there to again, move the bug out of sight.
If no success trying to shake it out of view, you can take the monitor to a shop where they probably have a shelf full of similarly infested monitors.
Good luck and please keep us posted.
