Vertical control of viewing frame needs adjustment.
Our LCD projector projects an image of the desktop with the top half of the screen at the bottom and the bottom half on the top. I have tried the menu adjustments...but nothing is correcting the problem. I am using the LCD projector with an Apple G4 laptop with correct connections. It has worked in the past...but just started messing up recently. How can I correct this adjustment?
Re: Vertical control of viewing frame needs adjustment.
Did you try going into MENU --> PICTURE --> SIGNAL MODE, and then pressing > to go through all the signal modes? On mine, most of the signal modes split the screen weirdly as you described, but one of them (in my case XGA3, but I'm not using a Mac) looks right.

1. A button on your remote that says either: ARC, Ratio, 16:9, 4:3.... Some remotes have a picture of a square with arrows pointing out towards each corner..... I'm unfamiliar with this set, but it sounds like a widescreen, so give it a go

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.
Adjust the screen area of the computer’s display settings to match the projector’s native resolution. Refer to your projector documentation for the optimum or native-resolution setting for your projector model. If you can't find this information or are uncertain, most projectors support a maximum of 800 x 600 pixels.
With certain laptops, you might need to disable the laptop display to obtain the best image, especially when the native resolution of the laptop exceeds the native resolution of the projector.
Font smoothing will automatically generate a cleaner font outline, both on your laptop and on the projector. To apply font smoothing, do the following:
In Control Panel, open Display.
On the Appearance tab, click the Effects button.
In the Effects dialog box, select the Use the following method to smooth edges of screen fonts check box, and then select Standard or ClearType in the list.
If the projected image is dimmer than it was on the laptop, check your projector documentation for information regarding lamp timers. If the lamp life has expired, replace the lamp for maximum brightness.
If the projected image is not rectangular, try one or both of the following:
Make sure that the projector is perpendicular to the viewing screen.
Raise or lower the projector.
If the projected image displays vertical lines, "bleeding," or spots, try one or more of the following:
Adjust the brightness of the image.
Check the projector lens to see whether it needs cleaning.
Adjust the sync and tracking on the projector.
