Furkin 21:32 18 Mar 2018 Locked Hi, I've just sold an old vga monitor. It was fine when I listed it, but I always test again before sending. I tested it on my old laptop, which I no longer have, so I connected it the vga on my desktop, but my Win 10 dosn't seem to see it. It's taken me all day to find where the correct area is, as my C.P dosn't have an Appearance button. Any ideas please ? This thread is now locked and can not be replied to.
