Make the picture fill the screen

Hello

It is likely that you have the "picture size" set to a mode that does not match what the channel is actually providing.

Go to the Menu options on your TV and then look for the Picture options. Change the size between the different options (typically 16:9, 4:3, Wide, Fit to Screen, etc.) and see which mode works best for the Fox and CBS broadcasts.

It is likely you have the TV set to Wide or Fit to Screen. Both change the settings to make 4:3 broadcasts fill the screen of a wide screen TV. Changing this to 16:9 should allow you to see the information on the sides and bottom of the screen again.

Go to picture/video settings and make sure your screen size is set for 16:9 or wide screen ratio.............

If you have dish or cable go into menu settings and check and make sure the same is true

Sometimes on the remote there is a picture size/mode button you can press to change the screen size

Normal or Wide would be widescreen
Stretch is zoomed picture that fills the screen
Letterbox is the square box screen

It sounds like a picture setting problem to me
I would try those things first

I’m happy to assist further over the phone at https://www.6ya.com/expert/robert_54ae41aaaffbab00

I found the user manual online, and the pictures in it are really helpful and make this make a lot more sense, but:
1. Press [SCREEN MODE], to switch the TV aspect ratio.
2. Press [SCREEN MODE] repeatedly until the normal screen displays.
NOTE: • Some programs may not offer all display mode options.
4:3 Programming
[Sidebar] Sidebar displays a 4:3 picture at its standard 4:3 size. Sidebars will be displayed on the right and left edges of the screen.
[Full] Full displays a 4:3 picture at a 16:9 size, with horizontal elongation necessary to fill the screen.
[Cinema] Cinema displays a 4:3 picture at a 16:9 size, with less horizontal elongation necessary to fill the screen because a little bit of the top and bottom edge of the screen will be cut off.
[Wide] Wide displays the center of the picture as original size and the outer sides of the picture will be elongated. The size of the picture will depend on the original signal.
16:9 Programming
[Full] A picture is displayed at 16:9 size as it is.
[Zoom] Zoom displays a 16:9 picture without changing its horizontal and vertical ratio, at its maximum size.
[Cinema] Cinema displays a 16:9 picture with vertical elongation.
[Expand] Expand displays a 16:9 picture with horizontal elongation

Hello
This is an issue because most television programming is produced in a 4:3 aspect ratio. The minority of programming is high definition, which is produced in a 16:9 aspect ratio. Because televisions are made in either a standard (4:3) or widescreen (16:9) format, there is always a conflict with an image being stretched vertically or horizontally. In the case of widescreen televisions, the stretching is horizontal.
Picture Modes
Luckily, most if not all widescreen televisions have a picture mode that allows the user to toggle between a wide (16:9) and standard (4:3) mode. This means that a person can watch non-HD programming in the 4:3 picture mode, and then go to widescreen when watching HD programming. Some TVs have a picture mode that will automatically adjust to the correct aspect ratio. Other people will watch all programming in the wide picture mode, and learn to adjust to watching a stretched picture.
A stretched picture is when a 4:3 image is pulled on the sides to fill the entire screen. People and images end up looking fatter/wider and shorter.
So, what's the big deal?
Some people don't like a 4:3 picture stretched or distorted because it does reduce the overall visual and picture quality. Some people don't like the bars on the side of the screen when a widescreen is in a standard (4:3) picture mode because it looks different.
Solution
There is no fix-all solution for this issue, unless you own a TV that will automatically adjust to the intended aspect ratio. The stretching of the picture is a side-effect, the price we are paying for the better resolution that is digital and high definition. This is definitely something to consider when buying a television, but keep in mind that there is no right or wrong within this issue. It is just the way it is, and there is no way around it unless you buy a 4:3 aspect ratio television.
Hope these lines will clear the issue, if so do rate the solution

That is because you are trying to display the 4:3 old standard TV source to fill in the 16:9 screen. If you want to watch it with correct aspect rarion, you will need to use the 'ASPECT', 'PICTURE MODE', or 'WIDE' btton on the remote to change it.
Most people does like to see black bars on the left and the right sides of the picture when view in 4:3 mode so they stretch the picture to fill the screen, and that is what you will get, people will look short and wide.
Please see your owner manual that will explain the aspect ratio of the pictures in various modes.

hi bob you should be able to adjust the screen size via the menu on the monitor itself, (Available in Analog mode only) Note When TV signal is input in AV mode ,select “Screen Fit “to adjust vertical position in 0-6 levels. Image Size Note Supplied for the wide models only such as 16:9 or 16:10. You can change the size of the screen displayed on your monitor. PC signals • Auto - The screen is displayed in accordance with the screen aspect ratio of the input signals.• Wide - A full screen is displayed regardless of the screen aspect ratio of the input signals. Note • Signals not available in the standard mode table are not supported.• If the wide screen which is the optimal resolution for the monitor is set on your PC, this function is not performed. AV signals • 4 : 3 - Sets the picture to 4:3 normal mode. • 16 : 9- Sets the picture to 16:9 wide mode. • Screen Fit- Use the function to see the full image without any cutoff when DVI (480p/576p/720p/1080i/1080p) signals are input. Note It can only be selected if an external input is connected to the DVI terminal and the 'PC/AV Mode' is set to 'AV'. • 4 : 3 - Sets the picture to 4:3 normal mode. • Wide-Sets the picture to 16:10 wide mode. • Screen Fit- Use the function to see the full image without any cutoff when DVI (480p/576p/720p/1080i/1080p) signals are input. Note • It can only be selected if an external input is connected to the DVI terminal and the 'PC/AV Mode' is set to 'AV'. • When the panel is of 16:10,the screen size options include “4:3”,”wide “,”Screen fit“.hope this helps

Set the all settings to wide, not auto as if the player is set to 4:3 format then this sends a signal to the tv telling it so.Go into the setup menu and choose picture format set to 16:9 or wide. Set the tv to auto and this will keep all picture inputs to origional format. I.E. if it was recorded in 16:9 it will play in 16:9. You could set the tv to 16:9 but it will distort the picture on 4:3 recordings.

There should be a screen mode button on your remote. Full, Wide, Zoom, and Etc. Sounds like your putting a 4:3 video into your 16:9 screen. Which causes the normal "box" video to be stretched to the wide "rectangle" video. Just keep the screen mode on Full or Normal. You should have empty spaces on the sides of the video and when a HD program comes on, the sides should fill in automatically.

There could be a problem, but verify the settings as listed in the owner's manual as follows:

1 Press the MENU button to display the menu.
Press the ▲ or ▼ button to select Picture, then press the ENTER button.
2 Press the ▲ or ▼ button to select Size, then press the ENTER button.
3 Press the ▲ or ▼ button to select the screen format you want.
Press the ENTER button.
Press the EXIT button to exit.
• 16:9 : Sets the picture to 16:9 wide mode.
• Zoom1 : Magnifies the size of the picture on the screen.
• Zoom2 : Expands the Zoom1 format picture.
• Wide Fit : Enlarges the aspect ratio of the picture to fit the entire screen.
• 4:3 : Sets the picture to 4:3 normal mode.
• Just Scan : Use this function to see the full image without any cutoff when DTV
or HDMI 720p/1080i signals are input.
Press the P.SIZE button on the remote control to change the picture size.


And realize the restrictions as listed:

• In TV, VIDEO, S-VIDEO, and COMPONENT(480i, 480p) modes, all screen
modes can be selected. (16:9 ➞ Zoom1 ➞ Zoom2 ➞ 4:3)
• In COMPONENT(720p, 1080i) or HDMI(720p, 1080i) mode, 16:9, 4:3 and
Wide Fit can be selected.
• In Zoom1, Zoom2 and Wide Fit modes, you can move the picture on the
screen by pressing the ▲ or ▼ button.
•You can not change the picture size when PIP is set to Double.
•When Double ( , ) mode has been set in PIP, the Picture Size cannot
be set.
•Wide Fit can be used when watching a Digital HD (High Definition) signal.
Wide Fit sets the optimum picture format by expanding it both horizontally and
vertically. For example, you can reset the picture in 4:3 format to 16:9. Wide Fit
does not support all external devices (DVD, VCR etc.).
