I have an Ehman (aka Lapis) full page display connected to my mac plus. Recently vertical lines began appearing on the FPD 16 pixels apart on every second line. The lines appear at first under the mouse pointer but soon the screen is filled making it difficult to read. The mac's original screen remains unaffected. Sometimes restarting helps, sometimes not. The problem is also intermitent, it may appear 10 min after I've been working then disappear, then reappear then disappear.....
The plus is running system 7.0.1 with tuneup 1.1.1. and no non-apple extensions or control pannels.
Has anyone else experienced a similar problem? Any suggestions would be appreciated. Also, does anyone know if these monitors which have custom video cards as daughterboards can be run off of internal video circuits (ie the Performa's, IIci's or IIsi's)??
