Mac bootup, wrong resolution

[grubby0]

One day, OS X booted up with a resolution of 1366x768 randomly. My monitor's native is 1440x900. This was easily fixed in System Preferences, however when OS X is booting up, the boot menu (the Apple logo and the gray background) still shows up in 1366x768, as does the Boot Camp menu.

I have tried verifying my permissions, verifying my disk, and resetting my PRAM. Is there any way to fix this?

Hmm. I'm grasping at straws, but type "cat /Library/Preferences/SystemConfiguration/com.apple.Boot.plist" into Terminal and paste the results here.

Yeah... doesn't look like much
