How can I make the picture size fit the screen? I loose picture around the edges. Seems like it is displaying at a larger size

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

Format will not usually work here--look carefully in Box's menu for an adjustment---not 4x3 or 16x9 but a size adjustment/s.

Use the aspect button on the remote till you get the size you want

IT IS NOT HARDWARE PROBLEM
Change screen resolution

Screen resolution refers to the clarity of the text and images on your screen. At higher resolutions, items appear sharper. They also appear smaller, so more items fit on the screen. At lower resolutions, fewer items fit on the screen, but they are larger and easier to see. At very low resolutions, however, images might have jagged edges.

For example, 640 × 480 is a lower screen resolution, and 1600 × 1200 is a higher one. CRT monitors generally display a resolution of 800 × 600 or 1024 × 768. LCD monitors can better support the higher resolutions. Whether you can increase your screen resolution depends on the size and capability of your monitor and the type of video card you have.

Text and images are sharper and smaller at high screen resolutions

Text is larger and easier to read at low screen resolutions, but images are blocky and fewer items fit on the screen

1. Open Display Settings by clicking the Start button , clicking Control Panel, clicking Appearance and Personalization, clicking Personalization, and then clicking Display Settings.
   

2. Under Resolution, move the slider to the resolution you want, and then click Apply.
   

if you mean your desktop/screen saver

Adjust the Aspect ratio. The manual will tell you how.

press menu or red button ( NOT STANDBY ) find pic format( aspect ) and change screen size to match tv

Hi thanks for this but no to no avail. There is nothing wrong with the display itself - everything works but the problem is that the VIRTUAL size of the screen is 1500 x 950 instead of 1440 x 900 if you get my meaning. I wish i could find a way to shrink back the virtual screen size to 1440 x 900 so that it fits the exact physical screen. ie. if i was to play a DVD on full screen i would only see 95% of the picture because the virtual screen is larger than the display. And the virtual screen would move right if I shifted my mouse to the right edge. Still puzzled.

Is this a DLP or a conventional 3 tube rear projection?
