They are, for all intents and purposes, close enough to 16:9 to be considered synonymous.

Don’t be thrown off by other wide-screen aspect ratios.CNET reviews will always indicate how aspect-ratio control is restricted, so be sure to check when making a purchasing decision.

Some HDTVs, especially older models, restrict the number of available aspect-ratio choices with 480p sources as well.

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). Almost every HDTV has aspect-ratio control, but most sets available today limit the number of choices you have, depending the incoming resolutions.

Not every aspect-ratio choice will be available at every resolution.

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. 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. 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. The next two pages suggest several solutions to common aspect-ratio problems.

Make sure your new TV has aspect-ratio control.

Video sources attached to these models should be (counterintuitively) set to 16:9, because they’re designed to display the full vertical resolution of a wide-screen image within the letterboxed area. The one exception is for 4:3 TVs that offer a feature called vertical compression or anamorphic squeeze. Make sure you set each device to the setting that matches the TV to which it’s attached: 4:3 for standard TVs, 16:9 for wide-screen monitors (nearly all HDTVs). Most modern video sources–DVD players, game consoles, satellite and cable boxes, DVRs, and even the video iPod–have an aspect-ratio setting.

Make sure your video settings match your TV’s aspect ratio.

Some critical caveats:īefore we examine the details of those aspect-ratio problems and solutions, it’s important to affirm five key points:

But as soon as you try to watch 4:3 content on a wide-screen monitor or 16:9 content on a 4:3 TV, you need to make some choices as to how you’ll compromise. On the other hand, 16:9 is the native aspect ratio of most HDTV programming it is 78 percent wider than it is tall, or fully one-third wider than 4:3.Īt comparable screen sizes, the wide-screen image is a distinct improvement: it offers a larger image, and the horizontal orientation is more akin to how your eyes–next to each other, not on top of one another–view objects.īoth of these formats work perfectly well when they match the TV screen’s native aspect ratio–standard programming on a 4:3 screen (any 1950s to 1990s Nick at Nite fare, for instance) and any newer, wide-screen material on a 16:9 set (HDTV programming or most DVDs). All the older TVs and computer monitors you grew up with had the squarish 4:3 shape–only 33 percent wider than it was high. The two most common aspect ratios in home video are 4:3 (also known as 4×3, 1.33:1, or standard) and 16:9 (16×9, 1.78:1, or wide-screen). The concept is simple enough: aspect ratio is the fractional relation of the width of a video image compared to its height.
