Hey Afterburner, you were right and I think I may be cured!!! It seems it was my monitor settings which is a LG 4K TV. I reset the settings to default and tweaked a little from there and although there is a little hint of the old problem, it is very much better now, to a level I can live with.....hooray!!! Afterburner, I want to thank you for your kindness and support, sticking with me, and getting me through my problem. You are a star Sir!
