As Panasonic plasma televisions continue to evolve, size, picture quality and features continue to improve. You will discover several ways to adjust your Panasonic TV images, including with the zoom feature, which allows you to fill the TV screen with the image. Zoom becomes handy for recording letterbox format movies to DVD, for example. Letterbox refers to videos with horizontal black bars at the top and bottom of the image and the zoom feature cuts out the top and bottom bars, so the sides match up with the ends of the picture screen. Knowing how to adjust your Panasonic plasma zoom can enhance your viewing experience.
Turn on the Panasonic TV, press "TV/Video" on the remote, then "TV."
Press the "Menu" button on the remote, then one of the arrows underneath the Menu button. Press "OK" to advance to the next menu until you get to the Picture menu.
Select "Zoom Adjust" from the Picture menu, and then "V-position" or "V-size" to adjust the vertical image position and size.
Select "Zoom" to enlarge the image size of the 4:3 aspect ratio. Aspect ratio represents the video width of the image on your TV screen compared to its height. The standard television image has an aspect ratio of 4:3 (or 4 x 3), which means the image you see appears 33 per cent wider than its height. Widescreens have an aspect ratio of 16:9 or (16 x 9), meaning the image you view appears 78 per cent wider than its height. You will find 16:9 aspect ratio on most HDTV programs.
Press "OK" on the remote to reset the aspect-ratio settings after using the zoom feature. This prevents possible image retention (or a ghost image) of the zoomed image, which could happen if the image was left on your television.
