Computer monitorWidescreen display

It is normal for a widescreen LCD display to have black borders if you're running a non-widescreen resolution or the program, game, or movie you watching does not support widescreen.

Microsoft Windows:
Make sure to change your resolution settings in Microsoft Windows to a resolution that supports widescreen.

DVDs:
Many DVDs support both widescreen and full screen mode. If you're using a widescreen LCD display make sure to display the movie in widescreen format. Additionally, you can change the aspect ratio in many DVD programs to fit your display.

LCD limitation

Due to architectural differences from the standard CRT monitor, an LCD has a set resolution often referred to as native resolution. For example, if an LCD had a set resolution of 1920 x 1080 but a user changed it to something larger, the size of displayed images will decrease, causing a black border to appear. To rectify this issue, most LCDs or laptop manufacturers have a utility that can "stretch" the pixel size, allowing smaller images to take up a full screen. This action will, however, decrease the quality of the image slightly (especially noticeable when viewing text).

Because the method used to enable this feature varies, it is recommended that you contact your laptop or LCD manufacturer for additional information.

Resolution was changed and monitor could not adjust

If the resolution was recently changed the monitor may not auto adjust or shift to the correct size. If this occurs, the resolution can be changed back to the original setting or you can manually adjust the monitor as instructed below.

Monitor needs to be manually adjusted

If a black border exists on the monitor it can be resolved by manually adjusting the horizontal or vertical width. Because each monitor is different, the method of adjusting this setting will vary; consult your monitor documentation. Additional information about these controls as well as example pictures of the settings can be found on our monitor page. Older monitors may not have the feature to adjust the horizontal setting; if this is the case, refer to the below notes:

Older computer monitor

Older monitors (15" monitors) naturally have borders. When this is not available it is due to the monitor design and it should be expected to see some black on the left and right of the monitor. If you believe this black area is to big, we recommend you contact your monitor manufacturer for additional information or consider getting a new monitor.
