The Picture On My LCD TV Is Blurry.

Last Update date : 2012.01.10

 Standard, analog channels and signals from devices connected to your TV through non-HD jacks and cabling will appear blurry on your LCD TV because of a fundamental mismatch between the resolution capability of your TV and the resolution of the analog signal. The standard, analog signal is a low definition, 480i signal with a resolution of approximately 640 x 480. In most cases, your LCD TV is a high definition TV with a resolution capability of 1366 x 768, 1440 x 900, or 1920 x 1080. It is this mismatch between the standard, analog signal resolution and the TV resolution that causes the problem.

Fixing the Problem

There is no way to fix this mismatch in resolution besides switching to an HD signal. There are, however, three ways you may be able to minimize the blurriness problem:

  • Reducing the picture size to 4:3
  • Using the Sharpness function
  • If you are using a cable box or some other external device, changing the connections

All three are described below.

Reducing the Picture Size to 4:3

If you are watching an analog channel or transmission, and the picture is fuzzy, you may be able to clear up the picture by reducing the size of the picture to 4:3, the native size of analog TV pictures.

To change the picture size to 4:3, press the P.Size button on your remote until 4:3 appears on the screen. The 4:3 picture has black or grey borders on the left and right.

Using the Sharpness Function

If the picture on your LCD TV is blurry, you may be able to clear it up with the Sharpness function. To use the Sharpness function on most Samsung LCD TVs, follow these steps:

  1. Turn on your TV.
  2. Press the Menu button on your remote. The Main menu appears.
  3. Press the Up or Down arrow button on your remote to select Picture, and then press the Enter button. The Picture menu appears.
  4. Press the Up or Down arrow button on your remote to select Custom, and then press the Enter button. The Custom menu appears.
  5. Use the Up or Down button on your remote to select Sharpness.

Note: On some model LCD TVs, you use the Enter button to select Sharpness.

  1. Use the Right arrow button on your remote to increase the sharpness.
  2. Press the Exit button to exit.
