You may need to check the settings of your mac book that permits you to output the signal to an external display. Also you may need to purchase a display port adapter (VGA, HDMI or DVI) that is compatible with the input connector on the projector
I am not familiar with your Hitachi LCD projector . However , I do have a little knowledge regarding video signals and inputs / outputs as well as connections . If your connecting cable is one piece (has no adapters added to either end of it ) I would believe your problem is simply a settings misconfiguration in your projector / computer , or both . First , access your startup BIOS / CMOS settings during the initial booting sequence in your computer by pressing F1 or whichever keys you press when you turn the computer on to access it . Then , in the advanced list , check your primary video input selection to be sure it is default. Then, once the computer is completely booted and you can click on your start selection , go to your video settings and check how to switch between internal and external display options . I say this because it is important that you are able to reroute your video signal to your SVGA Out from the laptop (for sure) and it is in fact in that video output mode. Once you're sure you have a signal going out of laptop through that port , go to your projector video input selections menu and select each and every input option available until the signal comes through . This will only work if you're absolutely 100% sure that your video signal is in fact leaving the laptop via the SVGA port connection .
check that you have a signal going out of the monitor socket on your lalptop.
On Dell with projector connected and switched on, press the blue fn button bottom left usually, and while holding, press one marked CRT/LCD, (maybe f8) this will cycle to the following.
laptop only, laptop and monitor, monitor only, while holding Fn button press until you have desired outcome.
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.
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?
Perhaps you can try lowering the screen resolution first of the laptop before plugging in the projector and then the Fn + F8. Thereafter, gradually increase the screen resolution until projector stops displaying.
The idea is that your current screen resolution maybe too much for the projector to handle. This of course is assuming that there is no hardware problem with the projector.
Hope this be of some help/idea. Post back how things turn up or should you need further information.
Good luck and kind regards.

If you can nvigate to the On Screen Display Menu, you should see an "all images" section on the main menu. There you will find brightness, contrast, color temp, white intensity, and gamma controls. You should be able to make adjustments from that menu to sharpen and brighten the image.
