Question about Akai PT4799HD Rear Projection Television

1 Answer

Alignment of picture is off balance

It appears the alignment is not working. When viewing widescreen formatted programs/movies the picture sets at an angle with wider black area at bottom right and upper left. When bulletins show across screen while watching programs you can read the portions in the lower right corner but then runs downhill (so to speak) as it moves to the left. Have tried to find someone in our area to come look at it but have not had any luck. Is there a way we can adjust this ourselves. We have had this TV less than 3 years.

How can I obtain a picture that covers the full screen width?


There are settings accessed through the TV remote that should allow you to adjust the screen size. Sometimes movie rentals are shown at widescreen (black at top and bottom of screen) due to how the actual movie was made to be viewed by the viewing audience.

How to zoom in on info


When TVs first appeared, they had an picture ratio of 4:3, which matched that of most movie screens at the time. Terrified of losing their business, movie studios struck back with "widescreen" films using 1.85:1 or 2.35:1 ratios. When widescreen TVs started appearing, they emulated those same ratios, but many TV shows (and some movies) were still in 4:3---and we were eventually left with a bit of a mess. Canny manufacturers, including LG, have solved the problem by allowing you to adjust the picture ratio on the TV to fit the program you're watching. If it's not set properly, however, your image will look distorted or cut off. A quick bit of troubleshooting can fix the problem easily.

  1. Press the "Menu" button on the remote and scroll down to the "Option" title (it should be second from the bottom ). Then select "Aspect Ratio." You should see a list of ratio options. You simply need to pick the one which fits the show you're watching.
  2. Choose the 4:3 ratio for older movies and TV programs. You should see a pair of bars on the left and right side of the screen. (That's okay: the bars keep the program in the same proportion in which it was filmed.)
  3. Select the 16:9 ratio for widescreen movies and for more recent shows to match their longer width. For some movies, you may see black bars and the top and bottom of the screen. Again, that allows the movie to be shown in the manner it was filmed.
  4. Pick "Set By Program" to automatically switch the LG TV between 4:3 and 16:9 to match whatever show is on at the time.
  5. Select "Horizon" to horizontally expand the image onscreen. It will fill the whole screen---eliminating the black bars to the left and the right---but it may look distorted.
  6. Use the "Zoom 1" option to zoom the image forward. That will eliminate the black bars at the top or the bottom of the screen, though you will cut off the edges of the image.
  7. Pick the "Zoom 2" button to select a midway point between "Horizon" and "Zoom 1." The picture is stretched, but not as much as with "Horizon," and fills the screen, but doesn't cut off as much as "Zoom 1."
  8. Use the "Cinema Zoom" button to enlarge the picture to fit the screen. This option allows you to adjust the proportion to your liking, rather than use the set proportions of the other aspect options.
  9. Exit the menu when you are done and watch your programming normally.

I purchased a DVD that states: Widescreen Format (Aspect Ratio 1.85.1) I'm unable to get 'widescreen/letterbox'. The movie shows up full screen or a 'stretched' view. All other movies I've...


On the DVD recorder remote: press function menu button: enter setup screen - scroll down to connection - TV aspect - select either 16:9 / 4:3 Letterbox / 4:3 Pan&scan. If you are using an older TV which is not a widescreen, set the aspect to '4:3 Letterbox'.

You should now be able to view your DVD movies from this machine through a 4:3 standard TV in letterbox format. (some DVDs do not allow pan&scan so letterbox or widescreen is recommended). Very rare that a DVD title is not compatible with 4:3 TVs. I assume your deck is set to output 16:9 aspect by default.

I find this is the cheapest and easiest solution and can save lots of dollars in service call-outs. You can always reset the unit back to shipping condition later if you need to, or in the rare case of digital channels disappearing from your tuner memory.

Picture is only in middle of screen, top and bottom of screen is blacked out


If you are watching widescreen format movie or tv programming on a non-widescreen tv, that is how it will appear. The widescreen is a wider picture so to show it on a less wide screen, it has to shrink down to fit. and leave blank space top and botton.

If not, sorry.

Bought a 19inch LCD Insignia TV yesterday at Best Buy. Everthing works fine except the picture won't fill out the whole screen. Can't find anything in the menu to adjust this.


On you remote control or panel buttons press the menu button. Using you on screen menu, use the up and down arrows to find the Settings Function, use right arrow to enter sub-menu. Use the up and down arrows to find the aspect ratio setting. Use the right arrow to enter the sub-menu.From here you can change the picture setting to : Normal wide 1: Wide 2 : Zoom: Cinema. Once you found your preferred viewing picture, set you choice with the enter button. Then use the menu or escape buttons to close the on screen menu. I hope this helps you with your problem.

Letter box picture when viewing blue ray discs on Sony BR player


All blu-ray movies are in Widescreen format. So your tv converts the picture to make it look like letterbox. There will be some movies that will have those little black bars at the bottom. There will be some movies that don't. There is nothing to worry about it is normall. 

Hope this helps

4.14.1 Understanding Viewing Features
Your LCD HDTV features four viewing modes and Picture-In-Picture (PIP)/Picture-by-Picture (POP) mode.
You can switch viewing modes using the remote control.
4.14.2 Viewing Modes
Normal Mode
The original 4:3 aspect ratio (1.33:1 source) is preserved, so black bars are
added to the left and right of the display image. Standard TV broadcasts are
displayed with a 4:3 Aspect Ratio. Movies in 4:3 Aspect Ratio may be referred
to as pan-and-scan or full frame. These movies were originally filmed in 16:9
(widescreen), and then modified to fit a traditional TV screen (4:3).
Wide Mode
When watching a standard broadcast or full-frame movie in this mode,
the display image is stretched proportionately to fill the TV screen.
When watching a widescreen (1.78:1 source) program or movie, the
display image fills the TV screen. If you are watching a widescreen
(1.85:1 or 2.35:1 source) program or movie, there will still be black
bars at the top and bottom.
Zoom Mode
When watching a widescreen (1.78:1, 1.85:1, or 2.35:1 source)
program or movie, the display image is zoomed proportionally to fill the
width of the screen. The top and bottom are cut off to remove most of
the source material’s black bars. This mode is good for programs or
movies with sub-titles.
Panoramic Mode
When watching a standard broadcast or full frame movie in this mode,
the 4:3 Aspect Ratio (1.33:1 source) display image is stretched
horizontally on the left and right sides to fill the TV screen. The center
of the image is not stretched.

Note: Viewing modes are saved based on input. For example, you lasted watched a DVD in widescreen
mode and then watched TV in standard mode. When you switch back to DVD input, the viewing mode
will return to widescreen.

Sounds like it is a widescreen TV stuck in standard view mode. Should have a menu option called widescreen or movie format.
Do you see the whole picture squeezed down or is it actually cutting off the sides of it?
