Force display to external monitor on boot

[tryingtimes]

I have a 2009 macbook that needs a new screen. I've replaced the monitor cable, but it still whites out. I can hook it up to a TV via HDMI and the display is fine, but it boots in extended monitor mode and since the screen on the computer is whited out I can't get to any of the applications or preferences to change the display to mirrored rather than extended. I've ordered a new (used) LCD display to put it in, but in the meantime is there anyway to force the laptop to boot using the external monitor as the primary screen so I can get to the applications? Or do I just wait for the new screen to show up?

Try turning it on and then immediately close the lid once it's on. Make sure you've got power and the display cable connected of course.

Good to know. I will try it too.
I have a late 2008 MB that has issues with the display.

That works. Thanks!
