What you're seeing in the INFO bar is the incoming signal. It is incoming at 1080p (it will denote 1080i if it is 1080i), and the input signal is at 60Hz. The television will then process the picture to show at 240Hz.
Hope that helps.
I have a Samsung ln52b750. Whenever I turn on the cable or blu-ray it says it is running in 1080 @60Hz. How do I change it to 240Hz?
