2 monitors but one broken. what will I see.

The LCD screen and inverter on my 27inch imac 2009,are malfunctioning so I often get a black screen after a few hours or a few minutes.

If I hook up a monitor to the imac what will I see. Hopefully I can then use the system as per normal.
is this feasible for the 2009 imac?

It doesn’t sound like the screen is the problem, but if it is, or its the inverter or the backlight, that won’t affect the second monitor. If you set that up as the main monitor, it’ll work fine, but until you do it will appear as the second monitor, with just an empty desktop w/o a menu bar or any files on it.
