Digital BW, The Print

If that second monitor happens to be an Apple LCD it could be the voltage adapter, known as the brick. That is exactly what happened to mine. They were known to be defective on many models. Replacing it solved the issue.

The other thing is something could be wrong on the main board of a Mac. I had this happen also, replaced the graphics card and it was still going on with the G5, only the mac would keep going to sleep for no reason, but only when it was first turned on in the am. It is still doing that randomly and with other monitors also so it's most likely on the mother board of the mac.

My second monitor began getting hard to wake up, and would flash, or start dim, etc. before waking up in the AM. Now, I can't seem to get it to come on at all, though it will flash a bit when switching "mirroring" on and off...
