Boot menu on wrong display.

I recently bought a new monitor (the DoubleSight DS-263N) to use as my primary display. I also have a TV connected as a secondary display, which is always off, unless I'm watching a video or something.

Since hooking up the new monitor, my boot menu (holding alt/option during boot) shows on my TV even tho it's off.

In the display preferences, I have the menubar on my monitor. My monitor is connected to DVI #1 on the NVidia card, and my TV is connected to DVI #2. But my Mac still thinks my TV is my primary display instead of my monitor.

Where is this primary / secondary status defined? How do I make my monitor the primary display again? Is it a PRAM issue or something?

Thanks!

 

Ooh, you're right. My monitor is on the right, and my TV on the left. I tried rearranging them, but still no luck. The grey screen, the boot menu, the apple logo, are all appearing on the TV, even tho it's off.

I assume simply unplugging the TV would make the monitor primary again, but I'm still wondering what defines a display to be primary vs secondary.

 

I solved this by

1. Shut down.
2. Disconnect TV.
3. Boot up (forces monitor to become primary).
4. Shut down.
5. Reconnect TV (now it's secondary).
