The TV will have a widescreen option, usually on the remote somewhere or in the options in the setup.
Also, in Windows under control panel, display, appearance, you can dictate what aspect ratio you want.
If that doesn't work, they should have an 800 number in the manual of the TV, ftw.
You should be more like Cantrip.
