Picture sizes the picture on my 50" rear wont stay on wide screen are any others sizes for long before flicking back to 4.3 size, i just got it and not found all the tricks is there a button you press to hold it on that frame are is there somthing wronge wi it. cheers

select the menu button then go to aspect ratio settings. choose wide or 4:3 option aspect ratio.

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
You can set the picture size by remote control itself.

You can vide 480i format programmes in three picture sizes. 4:3, 16:9, and ZOOM
You can change the picture size by pressing the PICTURE SIZE button on the remote control.
4:3 Picutre size
To fill the screen, the top and bottom edges are extedted more widely, although the center of the picture remains near the former ratio.
If receiving a 4:3 programme, the image size is displayed in its originally formatted proportion.
16:9 picure size
This image displays the size of standard 16:9 with black bars at the top and bottom.
If receiving a 4:3 programme, the image is displayed with black bars at the top and bottom and stretched wider.

NOTE: If a fixed bar remains on the screen for a long period of time, the image can become parmanantly engrained in the screen and cause subtle but permanent ghost images. Never leave your TV for long periods of time while it is displaying these images.

Zoom picture size [for 16:9 formats]
The entire picture is uniformly enlarged --it is stretched the same amount both wider and taller (retains its original proportion). The right and left edges of the picture may be hidden.
OK.

Hi my name is Roety,
I can help you with your issue ,
　
　
There are a few buttons to adjust the picture size on different make TVs and even on the Cable/Satellite remotes .
1.Format
2.Aspect
3.Size
4.Zoom
5.Wide
6.#
First look on the TV remote, set it to Full ,Fill or Just or 16 x 9 (whichever your model uses) Samsung uses the P size button ,
Then on the cable/dish Box remote stretch (not zoom) is usually best.
On the box remote set the output resolution to 1080i only
And use 16x9 when if offers a choice.
Cable remotes use the # key as a zoom/size button.
Due to the fact there are 16 size/Formats available (3 or 4 being transmitted now). you may have to hit the zoom/stretch button on some HD channels.
But with these settings the picture will mostly stay full and help you avoid image burn from the edges being not on the edge.
Stretch will fill the screen and allow you to read the bottom.
Make sure you are on the correct input, sometimes TVs are connected on multiple inputs
(not necessary, only the HD input is needed)
　
If I have helped you with your issue
If you have more questions you can still respond
I will reply asap
Thanks

HDTV ready means that it will process HDTV signal to be viewed on you set. The size of your screen is still in a 4:3 ratio. Unless you have a true 16:9 size sceen you cannot get the full 16:9 picture. The actual physical size of the sceen is what makes TV's true HD or not. In other words, the screen has to be twice as wide as it is tall or 16:9. Your screen is almost square or 4:3. It can only show a compressed version of the 16:9. Thanks for using fixya.

You should have a button for "aspect ratio" (unsure of your brand of tv), could be marked "screen size - picture format" etc. Cycle through the sizes with this button until you come to auto or wide (set to auto to adjust the pictures to what is being transmitted - wide for a full screen but will stretch the picture to fill when transmitted in 4:3 format)

This is actually due to the signal format being sent down from the transmitters/broadcaster. They by defauly output 4:3 which your tuner in your TV interprets and rejigs it into 16:9. Te adverts as they come on are seen by the tuner in your tv as a change in aspect ratio, and therefore your TV is trying to best display these. However, if you go to your screen settings, you can change the screen auto format to your choice and this chould ensure that the picture always gets set to your choice. If set on default, it will vary between 'wide' and 'smart'.

I had the same problem with a 50". The only way I could fix it was to set my Bose system to 4:3 format and the tv to 16:9. Now you can use the zoom to get the right size

good luck

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.).


Keep us posted.

Normallly, if the picture size button on the remote for the television does not achieve the desired affect, then, a cable box or a satelite box is where the change needs to be made.
For example:
A Motorola Cable box needs to be set up to go to a wide screen or zoom when an analog signal is detected.
Some Dish Network boxes have Size buttons on their remotes and also in their main menu.
It's difficult to determine the repair without knowing the types of the peripherals.
Hope this helps.
