Televisions need to handle different input and signal types. Depending on the type of signal you are receiving, your TV will need to decide how to process this signal and display it on your screen.
Your TV has settings that you can use to choose how to process the signal and display it on the screen.
The screen cutoff is due to what is called an “overscan”. Most TVs automatically fit the input image to the screen, but some TVs cut out a portion of the screen (about 2-5%) and stretch the rest of the image to fit the screen.
Overscan solutions vary from TV to TV. If the tips below don’t work, or if you can’t find a particular setting in your TV menu, refer to your TV’s documentation or contact your TV manufacturer for more information.
Today, most TV content is broadcast in widescreen (16: 9) format. New TVs are built to display widescreen images, but many older TVs (4: 3) need to be tuned.
To ensure that you get the big picture on a 4: 3 TV, you need to use Freeview to adjust the aspect ratio of your receiver. Check your TV user guide for more information on how to do this.
Common 4: 3 display options are:
- Center Cut or Pan Scan: This allows the image to fill the entire screen. There are no black bars around the image, but the edges of the graphic are lost and the outer edges of the widescreen video are lost.
- Letter Box – With this option, you get the big picture that will be broadcast, so you won’t miss anything. There are black bars at the top and bottom of the photo, but it’s the same as most DVDs. When old 4: 3 (non-widescreen) content is broadcast, a black border appears around the entire image.
Best Fixes for TV Cutting Off the Part of Screen
All new high-definition TVs are equipped with multiple aspect ratios that allow you to crop a portion of your screen. If you chose the wrong option, you could crop parts of the movie or the video will have too much black padding around it.
In addition to the TV’s aspect mode feature, non-TV elements such as DVD players, DVRs, cables or satellite set-top boxes can also cause this problem.
Start with the TV menu or its remote control and go from there to solve the problem.
1. Television Adjustment
Use the TV’s Menu button or the remote’s Menu feature to navigate to the TV screen features. Screen features may appear on your TV with a different name.
Usually, you can find this setting in the “Picture” or “Input” settings on your TV’s menu system.
For details, refer to your TV’s operation manual. Once you find the setting, change it until you see “Normal”. In TV screen mode, you can change the setting from normal to zoom or widescreen setting.
If your TV is equipped with a vertical setting, this can also change the position of the image on the screen via this setting.
2. Satellite System or Cable
Like DVD players and TVs, many cable and satellite receivers come with screen setting adjustments.
This is because stations that broadcast high resolution signals usually project widescreen images along with the HD signals. To accurately portray this image on your TV, set the cable or satellite box normally.
3. Check Other Channels
Check the other channels to see if they have the same issue. If the image is choppy, there may be a problem with the channel, not the TV.
When receiving HDTV signals, changing channels often change the appearance of the screen. Depending on the broadcast, some of these channels may or may not show black bars at the top and bottom of the screen in normal mode.
4. Universal remote control
For quick and easy screen adjustments, use one remote as a “universal” remote and program it on all the devices used in your TV.
If you have a DVR system with cable or satellite services, use its remote control to control your TV, cable, or satellite set-top box, DVR, and audio system.
You have to be careful when purchasing a universal remote as older universal remotes do not have this feature.
With the right universal remote, it is very easy to scale the aspect ratio. Follow the instructions for programming the remote control using the user manual.
5. Check Your Cables
If you have a high definition (HD) receiver and an HDTV, you have to ensure the receiver connection uses an HDMI cable.
Connecting your receiver using standard definition cable or SD Cables, such as RCA or coaxial, can distort the shape of your TV picture.
