* Make sure your new TV has aspect-ratio control. The next two pages suggest several solutions to common aspect-ratio problems. But they will work only if your TV--or the video source, be it a satellite tuner, cable box, or DVD player--has aspect-ratio control. In general, all wide-screen HDTVs, most HDTV set-top boxes, and a few new 4:3 TVs can control aspect ratio in some way. Many DVD players have Zoom functions, and all can be set to work with both 4:3 and 16:9 TVs, but few have additional aspect-ratio controls.
* Every aspect-ratio choice will not be available at every resolution. Almost every HDTV has aspect-ratio control, but most sets available today limit the number of choices you have, depending the incoming resolutions. In most cases, you'll have full aspect-ratio control with 480i and 480p sources (generally standard TV and progressive-scan DVD, respectively), but often you get fewer options, or none at all, for HDTV resolutions (720p, 1080i, or 1080p). Some HDTVs, especially older models, restrict the number of available aspect-ratio choices with 480p sources as well.
