Picture too large for screen

Right click on the computer screen and bring up graphics. Go to graphics properties. There should be a title in the right column called "SCALING". open this and make sure the setting is on "full-screen".
the setting called (maintain aspect ratio) will cause the picture to run off both edges of the tv screen.

This has something to do with the setting. Try resetting through remote and see.

It's probably an issue of the "Aspect" or the "Screen Mode" you're in. I'm no TV repair expert, but if you look in your Main Menu for "Screen Mode" or even your remote might have a button labeled "Asp" or "Aspect" or "Mode"....or even "Wide" (which when pressed repeatedly will cycle through the most common 4 screen modes = Wide, Screen Fit, Zoom, 4:3.) The last one refers to the ratio aspect, but depending on your TV, they could be named differently.
Given your description, it seems you're in "Zoom" mode, since it's cutting off the edges of the picture. Put it on a station like CNN, which has a streaming ticker at the bottom and cycle through the options you have until you find the one you prefer. (Note: you should also be able to set this in your Main Menu somewhere as your preferred view, but some shows and movies might come through as full screen or 'Letterbox' regardless of your preference.
One final observation I've found on several units is that the remote button that's in the bottom right-hand corner (which may not be labeled as such) is the default location for your aspect selections. Push it and see what happens.
Good luck!

From what you describe your source material is 4:3 aspect ratio but you have the screen set to 16:9 zoom.
You need to goto your picture settings and find the automatic picture option and use that.
This will stretch the screen correctly without cutting of the edges.

crop the picture edges using photoshop

mine did not fix, picture is still huge and pushed to bottom of screen so the top is black all the way across

using the right or left arrows should change your screen sizes 16.9 4.3 and so on

Depends... 
if it's during a slide show, then there's a slide show option "screen fit or fill".  If you are set to fill then it will cut off edges, change the setting to screen fit.

or if it is cutting off all 4 sides when displaying a single photo, you may have the zoom turned on.  Tap actions / zoom and set the zoom back to 1x.

Thake it back! These screens are cut from a large sheet. The expencive models are cut from the middel of the sheet, Cheaper models from the edges. Chances of a dead spot are greater on the edges of the sheet.

take zoom offf on dish and the tv it sel use normal 16 .9 ,mode when u push screen in to it use 1024x768 60 hertz ok
