Hi,
I have a 20" iMac which has a screen resolution of 1680x1050. I have been using an additional 168x1050 monitor in dual screen mode. This was working fine with Snow Leopard, but it does not work after I upgraded to Lion. The screen appears to look fine for a few seconds then blanks out for a second and repeats. The only way I can use my extra monitor is by reducing the resolution to 1360x768.
Does anyone know of a fix?
