BDP-S370 won't let me change pictures size on the tv

[JMWilliams9]

I've just purchased a BDP-S370 that will not allow me to change the picture size when playing a BD, it only plays in the letter box format, how do I change alter the picture size?

Its the TV rather than the Blu-ray player. On Sony remotes there is a 'zoom' button at the top of the remote to allow you to toggle between ratio's so check your TV remote.

Thanks
