Picture Appears Stretched, Distorted, or Shrunken on My Laptop Screen

Résumé: Investigate the possible causes of the video issue experienced on your Dell PC LCD

Cet article concerne Cet article ne concerne pas Cet article n’est associé à aucun produit spécifique. Toutes les versions du produit ne sont pas identifiées dans cet article.

Symptômes

The image of the laptop screen appears stretched, distorted, or shrunk.

Cause

Possible Cause of Perceived Display Problems on LCD Screens

The Dell portable computers with high resolution displays are optimized for specific resolutions. As a result, using display resolutions that are different than these optimal settings can result in visual distortions on the screen.

For example: If a computer has a 15.0+" SXGA+ screen with an optimized resolution of 1400x1050 and the screen's current resolution is set to 1280x1024 pixels, the display will shrink resulting in a black border surrounding the edges of the screen. Also, all other lower resolutions may be stretched to fit the screen. No border will be visible, but fonts may appear slightly fuzzy.

Verify the LCD Type

Since the resolution settings vary from system to system, it is important to determine what type of LCD screen you have before adjusting your display resolution. To verify which LCD screen you have installed on your computer, you will need to view your invoice. Depending on your system model, your invoice should contain an entry similar to this:

220-2838 I8100,15 UXGA,PIII,1GHZ,T

Notice that the highlighted section above, while this example is for a Dell Inspiron 8100 computer, shows that the size of the screen is 15 inches and that the format of the screen is UXGA.

Adjust the Screen Resolution, Color Depth, and Refresh Rate

Adjust the screen resolution, color depth, and refresh rate in the Windows operating system.

LCD and Flat-Panel Monitor Types With Associated Native Resolutions

Table 1 and Table 2 specify LCD and flat-panel monitor types with associated native resolutions:
Native resolution of a LCD is the one under which the screen looks best. Operating Systems and programs give often various selection of resolution. If possible, it is advised to select a native resolution.
