I have a Hitachi CP-L500 LCD projector. It is connected to my laptop from the svga projector port to the svga port on the the laptop. It is making no signal connection. I have made sure the input button on the projector has selected RGB 1, where it is connected. The projector still says "no signal" or the "sync is out of range". Do I need driver software for this? How can I get it, if so? I am running Vista on a Gateway 64bit system. I also tried it on another laptop running Windows XP system 32. What can I do?

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 .
