Can't connect MacBook Pro to HDTV after setting invalid resolution

[corneliusR]

The first time I connected to my HDTV using a mini displayport-dvi and a dvi-hdmi adapter, it worked flawlessly. Stupidly, I set my TV to a resolution it couldn't support. Now the screen only turns blue until System Preferences eventually crashes and the TV gets no signal. I've tried clearing my PRAM, deleting the profile in the colorsync folder, and even deleting /Library/Preferences/com.apple.windowserver.plist out of desperation. I've confirmed that it's not a problem with the adapters by successfully getting another HDTV to work

Where could could OS X be storing the display's settings? Thank you

If you got it to work with another HDTV, use that TV to change the resolution back to something that yours will support.

I attempted that. However, OS X seems to store each TV's settings individually.
