Hi there,

 

I have a Philips monitor as a second display for my iMac. Whenever I plug in my printer to one of the iMac's USB ports (haven't sorted out a wireless connection yet), the second display automatically dismounts. To get it back I have to unplug the printer, then disconnect and reconnect the mini-display port connector for the second monitor.

 

Any ideas why this would happen? Can't think it's a power issue as both the printer and the monitor have their own power, and this doesn't happen when I plug in flash drives and other devices using the USB ports.

 

Any help with this annoying problem would be much appreciated!

Alex
