It all depends on what is the format of your TV. If you have a widescreen TV, then you need to use Corel VideoStudio Pro X4 to save in a compatible wide resolution, one you have to match with the TV's supported resolutions. Recommended is to save to 1920 x 1080 (FULL HD) resolution but that increases the file size, however, it's recommended that this resolution is the best for HD/FULL HD/LED TV's.
