Hi sup316,
· What resolution are you trying to output?
· Are you using a HDTV?
The problem seems to be the aspect ratio mismatch on your LCD TV. The aspect ratio on the computer is not matching with the aspect ratio on your TV.
Note: The steps below are applicable if you’re using LCD/HDTV
Most of the widescreen TVs utilize the 16:9 aspect ratio since this is the default widescreen size used for HDTV broadcasts. If you are watching a widescreen broadcast on your HDTV, then it should be in the 16:9 ratio and therefore should fill up your screen rather than displaying black bars on Top and bottom of the display.
Step 1: Change the aspect ratio on your TV
I would suggest you to check the manual that came with your TV to see how to change the video settings on your TV. You may need to change the video settings on your television to get the display correctly.
Alternatively, you can change the display settings on your HDTV through your computer by following the steps mentioned below.
a. Open Display Settings by clicking the Start button, clicking Control Panel, clicking Appearance and Personalization, clicking Personalization, and then clicking Display Settings.
b. Choose the monitor that you want to change settings for, adjust the display settings, and then click OK.
To select different display settings for one or more displays
- At the bottom of the New Display Detected dialog box, click Display.
The Display Settings dialog box opens, where you can change screen resolution, refresh rate, and color depth.
