We own a proton pltv-32c. the image coming in is larger than our screen (or the ratio is off). Basically the top and bottom of all images are being cut off (same for TV and video watching). What to do?

Banding of the screen usually means that the aspect ratio of the broadcast is different than the screen size ratio. Most modern TVs are 16:9 ratio. Most modern TV broadcasts and movies are as well. In those cases, when in HD mode, you will see the picture fill the entire screen. Older broadcasts and many syndicated reruns are in the old 4:3 format and will be banded. Also, some movies are in larger formats than 16:9 and will reduce in size in order to get the entire picture on the screen. That being said, most TVs DO have a stretch and.or zoom feature that will expand all images to full screen size. Be advised that this can result is image distortion, especially of the 4:3 ration broadcasts. Others will have some of the picture cut off and you may see some items such as network logos, etc. partially chopped off in this mode.

CHANGING THE SCREEN ASPECT RATIO: ( From Manual )
The TV can display images in four different modes: Wide, Zoom, Panoramic, and Normal. Each mode displays the picture differently. To change the screen aspect ratio:
1. Press the MENU button on the remote.
2. Use the Arrow buttons to highlight the Wide icon. Press OK.
3. Use the Arrow buttons to highlight your desired screen mode and press OK:
• Normal preserves the content's original aspect ratio. Since the 4:3 aspect ratio is not large enough to fill the TV's screen, black bars are added to the left and right of the display image.
• Wide stretches a 4:3 aspect ratio picture to the edges of the screen. Since the picture is being stretched, the display image may appear distorted. If the program is already formatted for widescreen viewing (1.85:1 or 2.35:1), then black bars will appear on the top and bottom of the display image.
• Zoom expands images with black bars to fit the screen.
• Panoramic expands the display image to fill the screen.
images may appear wider than intended.
If you are watching widescreen (1.85:1 or 2.35:1) content, black bars will still appear on the top and bottom of the display image. This option is only available when the TV is displaying a 480i/480p source.

Setup code to check with Proton TV is 1288. If you wish to get more detail about which brand remote control have setup codes to Proton TVs, check these sites. http://electrohelponline.blogspot.com/

If you have PLTV-32, check to see if your AC adapter is putting out the 24vdc for the backlight inverter, you are getting the 12vdc from the adapter for the sound and for the processor to turn on the TV, otherwise you may have backlight inverter board problems.

Check the aspect ratio settings you may have it set to 14:9 movie expand

The issue your having is aspect ratio. Some programs and commercials are broadcasting in a higher resolution so some fill the screen and some have black bars top and bottom. I suggest searching "aspect ratio for video". It would take me all night to type it out. But you need to know how the different resolutions change the size of your image. Also in the TV's menu you should see an aspect ratio option. Try the different settings to see if you can find the best.

Hey,

1080i or itll do 720p

You are probably in the "3:2" ratio print setting. This is accessed through the "F" button, under image quality. The 3:2 is a ratio of height to width which corresponds to a 4x6 inch print. The other settings are approx. 4x5.33 inches in h to w ratio. Just change the quality setting to the larger megapixel settings and the bars will disappear.
