Projected image is not the same as computer monitor
This projector is permanent mount and in frequent use for the past 2 years, with no issue.Current problem: Projected image is 3/4s of the computer monitor image.1/4th of the image on the smartboard is missing on the left side of the screen.Not an over projection, no image appears on the outside of the screen. Any help greatly appreciated.

The shadow is caused by projected light from the unit outside the image field. I have the same problem, and I just tend to ignore it. I have tried various settings and sizes to minimize the effect, but some shadow always remains. This is true with any projector.
Usually this is a hardware acceleration setting problem on the 'advanced' properties setting in your 'screen resolution' properties on your computer. Re-set the hardware acceleration to the 2nd setting and this should fix your issue. We have this regularly when we project on a double projector system and the one projector keeps shifting everything left until we adjust the hardware acceleration settings on the computer. No more issue.
No to your question. The lens is fixed it cannot shift horizontally only although there are projectors that can do this. I am sure you have the front foot retracted? I have had to do the same as you are doing or find a lower table.
IF I understand the problem from the limited info in your question, the problem is a distorted picture on whatever surface [probably a wall, or screen] onto which the image is projected.
With all lenses, the axis [centerline of the lens projected] MUST be absolutely PERPENDICULAR [in both the vertical and horizontal planes] to the perfectly plane [flat] surface onto which the image is projected.
IF for example, the projector is mounted in a rear corner of the room, and the camera is aimed downward and to one side to project the image on the center of the opposite wall, or a screen located there, the image will be distorted. It will be larger on one edge [fartherist from the lens] and smaller on the opposite [nearest] edge.
If it is non-perpendicular in only one axis, then two opposite edges will be different lengths, and if out of perpendicular in two axis then no edges will be the same length.
The solution to this problem is that the center axis of the lens must be perpendicular to the surface projected on, in both vertical and horizontal axis.
Hi, I have found out that you must have the laptop set to an external monitor, in the control panel, display area, click on 2, then you must have the projector turned on before you start the laptop so it can recognize that the projector is there. Also make certain that you allow the unit to cool off by turning the lamp off, leaving the fan on and open the door where the projection lens is located.
Looks like your projector has done it. Thats acommon trouble to ageing polirising lens, usually the blue. less blue, the green and red make up the yellowish image on the screen. The blue is bombarded with tremendous heat from the lamp and it fade and wash out. If its free, its worth replacing. Get quote for the poliriser; 2 pieces each color. Good Luck.
If you are plugging in a monitor cable, it is most likely a cable issue. I would try another cable and make sure the cable is seated firmly into the projector. If that doesn't help, check the port on the projector for bent or missing pins because it seems that not all of the video information is reaching the unit.
