I am trying to attach an external monitor, Acer V223w to my MacBook that's running Windows XP (via Boot Camp). When I do this, the (internal) display on the MacBook flashes between the normal desktop and black endlessly.
Note that (immediately) previous to attaching this monitor, I had the MacBook attached to another monitor (Acer AL2423W) and it was working great. Possibly this has something to do with the problem: maybe there is some "remnant" driver or setting that is causing a problem and that I can get rid of somehow.
When I attach the monitor to the MacBook, in the device manager, 5 or so "Plug and Play Monitor"s appear. Also, nothing appears on the external monitor. I have tried deleting all the Plug and Play Monitors from the device manager, but that doesn't help. I have found no way to eliminating the endless flashing of the MacBook's display.
In any case, I very much want to use an external display, but plugging one in makes the MacBook unusable. Any advice is appreciated. Thank you.
