Right-click on the Desktop, go to Properties. Then go to Displays, and click on display 2 in the diagram. Then change the resolution to your TV's native (for 720p TV 1360x720).
It isn't as easy to configure as a Mac, but you get there in the end![]()
Most 720p TV's have resolutions of 1366x720 (but usually appears as 1360x720). Extra pixels, not less.
Well, the standard for 720p broadcast assumes a resolution of 1280x720. Most televisions that are 720p such as DLP televisions are 1280x720 fixed pixel displays, none of this 1360x720 or whatever resolution that makes no sense given the standard in place.
If the MBP was designed to not be able to output at one of the HD standard resolutions then that is just silly.
