Uuhh...I'm not sure what the monitor test pics are going to accomplish for me (they are mesmerizing), but anyhow, I changed the background of both screens to Black, which certainly will help. I have a call into HRD to change their logbook background also, which I can't figure out how to do. That's what's on the left screen all the time by necessity while making QSO's and looking up call signs. I'll also have to do the same thing for their DM-780 Digital window. The Firefox browser I tried to change, but that didn't work either, but it's not onscreen most of the time. I installed the Black "Theme", but it doesn't change the window color, only the area around it. And my Ophthalmologist is just down the street. It's been two years, but I'll ask her about these computer glasses. Thanks, guys, much appreciated.
