How to Change a Sony Bravia TV's settings from 1080i to 1080p resolution?

Like anna444 said, most tv's automatically adjust to the signal that is being sent to your tv. for instance Call of Duty:Black ops can send up to a 1080p signal while Killzone 2 can only send up to a 1080i signal. The difference between them is that 1080i gives an interlaced pictures which are horizontal lines that make up the picture. 1080p are just consecutive pictures that make up the movement of the video. Hope this helped

Most televisions automatically display the highest possible resolution based on what it is capable of displaying and the type of signal it is fed. For example, if your television is getting a 720i signal, it will automatically switch to a 720i signal. If the input signal is 1080P, the television should automatically switch to 1080P mode.
