I've got a radius 19" TPD that seems to have a problem with light objects on black backgrounds. I found that when using After Dark or any other program that displays light colored objects on a black background there was a tremendous amount of ghosting. I think this is caused by the 100 Hz refresh rate it's being run at but if so I don't know how to fix it. Any help?-------------------------

Is this ghosting trailing animated objects (eg. After Dark)? If so,
the monitor was not designed for animation: the phosphors probably
last longer than normal in order to reduce flicker, thus eyestrain.
It is doubtful that you can "fix" this.II2II

The ghosting is trailing animated objects, however, the ghost of the object is still visible almost a second later. The monitor, being a Two-Page Display, obviously was not designed for animation, but the persistence is to the point where it's hard to believe they designed it that way.-------------------------

I pulled my TPD out and was pleased to find it was working properly
(it wasn't when I put it away). Unfortunately, I don't have anything
which displays white on black to test it against.But ghosting is normal. I have run into it on my iMac (xscreensaver
displays bright objects on a black background). Perhaps it is more
noticable on the TPD because you are watching animation as bright on
on solid black seems rare these days. I still think the phosphors is a problem. If the refresh rate is low,
they would need phosphors that fade more slowly to avoid flicker. Old
NTSC monitors (eg. Apple IIgs) were like this. II2II
