Using a second monitor as the primary display with MiniDisplayPort

I've got a new iMac, but the screen seems to be straining my eyes. I'm trying things like scaling the display, lowering brightness, changing desktop layout, etc, but if all else fails...I'd like to go back to my old external monitor.

So, my question is...if I connected this monitor to the MiniDisplayPort on the iMac, could I use it as a single primary display, or would I have to use it as mirrored or secondary?

iMac, OS X Mountain Lion (10.8.5)

Hi Brian,

Thanks for using Apple Support Communities. You can mirror the displays or make whichever display you want the primary in Extended Desktop mode. See this article for details:

How to use multiple displays with your Mac

The white bar at the top of the left blue box represents the menu bar and determines which display is your primary display. To change your primary display, click the white bar and drag and drop it on the blue box representing the display you would prefer to be your primary display.

Cheers,

- Ari
