How to Troubleshoot Vertical Lines on an LCD TV Screen

Updated February 21, 2017

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.

Press the "Menu" button on your remote control and open the "Picture Settings" sub-menu.

Select "View" from the list of options.

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).
