How to Troubleshoot Vertical Lines on an LCD TV Screen

There are two prevalent formats for video programming: full screen and wide screen. LCD TVs are designed to show a wide screen picture to go with high-definition (HD) programming. When standard-definition (SD) programming is watched on an LCD HDTV in its default settings mode, there will be two vertical lines on the right and left sides of the picture. You need to go into your TV settings menu to troubleshoot this issue.
jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); });
Instructions

  1. 1 Press the "Menu" button on your remote control and open the "Picture Settings" sub-menu.
  2. 2 Select "View" from the list of options.
  3. 3 Choose a viewing mode that will eliminate the vertical lines. Select "Zoom" to crop the on-screen image to fit the screen. Select "Wide/Widescreen" to stretch the on-screen image to fit the screen, or select "Panoramic/Panorama" to stretch the sides of the onscreen image to fit the screen (recommended).

My Vizio LCD HDTV 32in. doesn't seem to "center" the picture on sports programs so when they have a score box in the upper left corner most of it is cut off and can't be seen. Doesn't matter how I adjust the screen, bigger or smaller, the picture doesn't seem to be centered to allow viewing of the whole thing. Is this the TV or the channel? Always happens on sport games (baseball, football, basketball).


This is a common complaint. To be frank I don't have the exact term for your Vizio, but most recent LCD and plasma TVs have the ability to "zoom" or adjust "picture format" (those are two commonly used terms) depending on the signal source and format.

it has to do with the fact that currently there are both classic style format 4:3 signal sources as well as new HD 16:9 signal sources and on top of that it may happen that a 4:3 signal source is distributing adjusted image from a 16:9 or other signal source. Think cinema adjusted to run on classic TV - remember the vertical strip of image with two huge black areas below and above it?

Well the ZOOM or PICTURE FORMAT allows to adjust such an image so that you cut the "void" are by scalling (enlarging) the visible area to fit the whole screen.

A problem then appears when the signal source is normal and showing full screen. Then, because of the enlargement, you start missing some of the picture. Before there was nothing there because it was showing adjusted wide (cinema) format to the TV box format, but when the new TV box format gets enlarged it sure starts missing around the edges.

That's what you're seeing.

More and more TVs do not have the ability to adjust that through the TV itself. Don't ask me why, but they can only do it through the remote.

So if you have an original remote there MUST be a button there that's called ZOOM or FORMAT.

It does the trick.

Hope this helps. If it does do not forget to rate it.

PICTURE TO BIG AT THE SCREEN.CAN NOT SEE THE PICTERS MARGIN AT THE SCREEN.HOW TO ADJUST(REDUCING PICTURE SIZE ON SCREEN)?


1) Power your wide-screen TV on and turn to a channel that is displayed with bars on the side. You need to leave this channel on to ensure you have properly adjusted your wide-screen TV.

2)
Find in your TVs settings where you can "stretch" the picture. Refer to your wide-screen TVs owner's manual for specific instructions. Some TVs may not refer to this adjustment as "stretch." You will be able to find all the information your looking for in the owners manual.

3) Adjust settings back to normal if you want to watch a program shown in 16:9 format. Keeping the screen "stretched" will cause programs shown in 16:9 format appear zoomed in, making the picture look really different.

My akai tv is set on full screen


You should have a button on the remote that came with the TV labeled: format , ratio , wide , picture , somthing like that, different brands of TVs call it different things and I am not familiar with the Akai branded TVs, but when you find it just press it as many times as needed to make the picture look as you want it to.
Good luck !

screen has borders when watching tv


This is common issue of the channels that use 4:3 format while TV is designed for 16:9. To get it disappear, you just go to picture option, choose WIDE FIT, this fuction will widen the picture to whole screen. Of course, you have to accept the picture is blur a bit.

Why do we have black bars on top and bottom of screen


Originally when 16:9 TVs were produced movies were being shot in 16:9 so that you had a full screen. Now they are being shot in 14:9 as it gives you a more cinematic experience. This is due to the fact that colours look more vibrant when they are placed against a colourless/lightless surface (such as a black panel) as for the bars on the side of the screen LuciferStarr is correct; it depends on the format in which the video was originally produced. For example most older television shows are still shown in 4:3 but newer shows and movies are produced in the widescreen format.
