Hello, I have an LG LED 42" TV and I am trying to set it up as a monitor for my Mac Mini running Mac OS Lion. Somehow I changed the resolution on the screen preferences window and now I get an "Invalid Format" on the LG TV. I've tried rebooting in safe mode and changing the resolution and that works, but as soon as I boot in normal mode I get the Invalid Format message. What can I do?

I tried it but i only heard two start up sounds instead of three. Should i try it again? i must say it is a hard key combination to hold with only one hand
I just finished start up in normal mode and I get the invalid format again.
I will try it again from the beginning
ok, i will delete this one too.
sorry, i was looking for it in the wrong place. I found it and deleted it.
I restarted in normal mode but i get the invalid format again
Ok, I will try it. But if it doesn't work can we go through your first suggestion step by step? I'd like to give it one more try.
The thing is that earlier today it worked just fine; just that the screen was a little bit off centre so I thought the resolution was incorrect. I tried several options; some worked others gave the invalid format. But after a few seconds the screen came back to the previous resolution. It is just that I don't know when i clicked on the keep settings button and it screwed everything up.
OK, so far so good. I logged in to the new Admin user and the TV is recognised. Now, will this work with the other two previously existing users?
I logged out from the new user and have tried the previous ones.
It works!!!! I had been breaking my head for almost 3 hours before finding just answer.comThank you so much.
