Dual Monitors go Black on Laptop

#1
Recently I've been having issues with my laptop and dual monitors. I have been plugging my laptop into the DVI port of external monitors. After a few days, my external monitor would lose signal if I selected to show the desktop only on monitor 2, but now, whenever I plug in my second monitor, both my laptop monitor and the external monitor go black. I've had this happen with two monitors now, and I can't think of what could cause this. Can repeatedly plugging in a monitor break it?

Have you cycled the monitor select function key?

Are you plugging in this monitor while the system is running? Tried changing cables?

The laptop display and external display may be different feeds. On my older dell, the laptop display got messed up but the external display was normal. It took a motherboard replacement to repair the onboard display.
