You shouldn't need a driver as long as the Mac video system resolution can be matched by the Dell projector. Considering you are using a Mac Pro I don't think this will be an issue. Have you tried it and it didn't work?
I tried all the available solutions and the MacBook Pro could 'see' the projector and adjusted resolution on the MacBook LCD accordingly. There continued to be no signal received by the Dell Projector.

Hi, You shouldn't need any drivers, it's a standard projector. Connect the whole lot together then turn on the projector then turn on the Mac. if that doesn't work try it the other way around. So far I have not had any problem with projectors (of any make) but there are times when the Mac doesn't recognise one at the first attempt.
HiA projector is just a monitor with a lens on the front. It does not need drivers. Just connect it to your video out-put port (all macbook pros have one) Drivers are only needed for projectors that connect by USB.
Dell projectors work best with windows operating system. Replacing the projector would still not resolve the problem since it is not compatible with Macintosh computers. I recommend that you contact Macintosh and ask if there is an available patch to resolve the issue.
They (Apple) might be right.
It could be that the projector is damaged, like the bulb, or it could be incompatible with your computer, but I don't think that is the case.
Try taking the projector to a computer repair place.
If you were using the Apple S-video adapter to connect to your Dell projector, please realize that MacBook models with NVIDIA graphics cards do not support this adapter. Otherwise, please be more specific about what model Mac you have and what adapter cable you are using.
Your Macbook should automaticaly find the best resolution, if everything was OK. Is there any HDMI input on the dell projector? What projector is it? Is there is an HDMI input, you can use a HDMI to mini DVI cable: better picture and sound than VGA, and will probably solve your problem
When connecting to exterior projectors, the video settings can be difficult to set up correctly. Try swapping the monitor in the display system preference and sliding your stuff to the other monitor. This is kind of a pain but it does work sometimes. The more you play around with that system preference the more you will figure stuff out. It is also possible that the particular projector is providing feedback into your mac. Try it on another type of projector and see if the problem persists.
