My olympus sp800uz lcd display square image only the lcd is not full how can i solve this

The camera automatically stores the date and time (and a lot more) with every image, however it will not deface your photos by scribbling a string of numbers across them.

If you want them printed, please refer to the documentation for whatever program you're using. Depending on the program and printer, you can print the date on the image, in the margins, or on the back. If you continue to have trouble, please feel free to reply to this post and specify the program you're using.

The scrolling wheel around the four-way controller is ideal for moving through images at different rates. Turn it aggressively and the display switches to several shots on the screen at once, which works surprisingly well in moving through a full memory card.

Pushing the zoom lever right magnifies the image in stages, up to 10x. Moving in the other direction offers two levels of thumbnail views followed by an 'event index' that organizes photos based on time and date taken.

1. You might be able to download foto's from the camera, when you do it manually from within the installed Olympus program. Windows XP has problems with auto downloading foto's from ib.
2. Otherwise, check if the computer is recognizing the camera (see LCD) and with the Explorer if a removeable memory device is available from the camera.
3. Try putting the camera into another USB port, or try the camera on another computer.
4. As an alternative, you might want to install a better and also free Olympus program:

The LCD screen on the Olympus SP-800uz camera is widescreen (16:9).
If you set the camera to take pictures in (4:3) ratio you het the black sides.

Solution:
Select a Widescreen Image Size (see the manual page 30) by selecting one of
the available Image Size settings 16:9 (L) (4288×2416) or 16:9 (S) (1920×1080).

Are you talking about the camera's LED screen, or your computer monitor screen?
Anyway, the Olympus SP-800uz camera has 4:3 image sizes and widescreen 16:9.
Just set your camera to the size you need to get your images shown fullscreen.
An alternative is to use a graphic (or tool) program that is able to crop your images.

Yes, your camera needs servicing.

If I understand your question right, you want to see your made pictures at full screen without black areas. Well, if you have a widescreen monitor, you can set the camera to take images in widescreen 16:9 format. Thera are menu settings: 16:9 L (4288x2416) and 16:9 S (1920x1080) or crop your pictures with a dedicated graphic tool program.

You might keep an eye open on eBay e.g. http://cgi.ebay.co.uk/Olympus-SP-800-UZ-REPLACEMENT-LCD-DISPLAY-SCREEN-USA-/330497907796?pt=Digital_Camera_Accessories&hash=item4cf335dc54

You mean that the image you take and playback is in 4:3 ratio. The default settings is 4:3. However, if you want to take widescreen (16:9 full LCD) images, just change the Image Size setting in the menu to 16:9 L (4288x2416 pixels) or 16:9 S (1920x1080 pixels). See the user manual page 30.

A histogram is a graphic representation of the distribution of brightness values in an image. The C-5500 has two histograms. One displays a real-time graph on the LCD screen as you compose your images and during the Quick View of images after they are shot. The DIRECT histogram displays potentially over and under-exposed areas in the image with a grid of squares—red for over-exposure and blue for under-exposure. You can set the histogram to OFF to prevent the histogram from appearing.
