Yesterday I connected my 2010 mini to a samsung 46" hdtv, and it was working fine in 1080p. For some reason I thought 1080i was better than 1080p, and clicked on it to see if it was working. The screen went black, and the tv says that the mode is not supported. I've been trying to figure out how to solve this, and suggestions seem to be to either reset the pram or boot into safe mode. However, I am not managing to do either. I suspect it is because I have a wireless apple keyboard, and that it does not properly connect in time to get the mini to get into safe mode. I don't want to buy a keyboard with a cable just to get out of this mode, so I'm writing here in hopes of getting some help. I have a 27" iMac and a 2008 Macbook Pro on the same network as the mini, if that matters. I also have a firewire cable in case that can be used. The mini is connected to the tv with a Kanex minidisplay to hdmi cable. Thanks for any suggestions.
