Data Projection - Not Quite Right!

.......Oh well, attempt number one didn't work!

I had assumed that the image coming out of a data projector would be projected straight out from the projector, but that does not seem to be the case.  I've got two Dell S320 that I bought in Singapore while we were on holiday there last year (Reason: I bought these through a retail shop in Singapore, it was so much cheaper than what Dell NZ  could offer, even after trying to negotiate with them.  In my view it's just not right that prices vary so much depending on the country you live in - ).

When I switch the projectors on with the projectors set to ceiling mounted, the image projected right down at the bottom of the screen.  I looked for options through the menu to change this, but no joy......I took the whole set up down to try again.

What am I trying to do?  Well, I'm now hoping to mount the projectors 'right-way-up' near the ceiling, but as these images show, with the short throw projectors, I've got them angled down at about 45 degrees and they are still not low enough!  I've sent an email to Dell Technical Support to se if there is something I'm missing setting-wise.


If anyone knows or can help please feel free to comment.

I'm planning on making jigs similar to the ceiling mounted ones to try and solve the problem.  As a start,  I used SketchUp, once again, to help with getting the dimensions right - I really do recommend this as it has helped me on this project and others on many occasions.

Even now after remounting the projectors it's still not right, but it's much better - so it will have to be on trial and error until I get it right.
