Changing your TV screen resolution

Learn how to choose the right TV screen setting, how to use the U-verse remote zoom button, and how screen shapes and resolutions impact picture quality.

Understanding screen shapes, resolutions, and settings

Your TV's screen resolution determines how many dots or pixels make up the image you see. The more pixels, the better the picture quality or definition. Then, some programs are in 3D TV adding the illusion of depth to normal 2D video to provide a realistic three-dimensional viewing experience. The perception of depth is attained through synchronized viewing of separate images by each eye.
Resolution numbers

An explanation of screen shapes, resolutions and definitions
  • SD, or Standard Definition, TVs display  480  lines of resolution top to bottom (480p). They are usually box shaped (4:3 ratio) but some come with a widescreen display (16:9 ratio).
  • All HDTVs, or High Definition TVs, are widescreen (16:9 ratio) but they come in two versions. Some display 720 lines of resolution top to bottom (720p), which is more resolution than Standard screens. The "p" means all the pixels get refreshed at the same time.
  • The highest resolution HDTV has 1080 lines top to bottom (1080i) which gives you the best picture quality. The "i" means the odd and even lines are refreshed alternately (interlaced), which displays motion in a better way.

Using the zoom button on your U-verse remote control

When you watch SD programming in widescreen mode on a widescreen HDTV, black bars will appear on the sides of the program. Follow these steps to fit the image to your TV:
  1. Press ENTER on your U-verse TV remote to view the current zoom setting on your screen.
  2. Press ENTER repeatedly until you reach one of the five zoom settings you want.
    • Normal displays the normal image.
    • Zoom 1 to 3 increases the zoom.
    • Stretch expands the image to fill the screen (may cause distortion of picture).

The zoom setting you choose will be applied to all channels.
