Unable to detect new Sanyo PLV-Z5 projector

I just got a new projector and made a presentation on Keynote match the resolution of the projector 1280 x 720. My Imac G5 will not detect the projector and give me the arrange, mirror, etc. questions despite trying to connect the projector with the computer asleep. All I get is a generic list of resolutions whenever I plug in the VGA connector. The projector displays the information but only fills half of the screen.
Any ideas?

Welcome to the forums, Bruce!

Just to be clear, even though the projector does not show up in the Display preferences, it nonetheless will show (some of) the iMac screen? That seems extremely odd.

Have you tried booting the computer with the projector attached? Have you tried a different VGA adaptor? Do you know if the machine works with any other external displays?

Thanks for the response.
When I plug the VGA adaptor on both my iBook and iMac, I get a long list of resolution choices that show up in the display list. This occurs whether it is connected to the projector or not. There is nothing about mirroring, etc. or showing the projector somewhere when I click the Detect button.
My projector is 1280 by 720 and so is my Keynote project so I would like to be able to use its native resolution.
All I get is what is on my computer screen. It seems to want to default to the 1024 x 760 and fills only half of the projector's projected image.
I have tried connecting with the computer asleep or rebooting with it connected but nothing shows up.
The Sanyo literature says it is Mac compatible.
Are there any other options?

If you are not getting options to mirror or span, it appears that OS X is not recognizing your projector at all. What is odd is that, if that is the case, I wouldn't think it would be sending a video signal out over the VGA adapter, and so the projector should not have any signal to show.

You might try a different VGA adapter, to see if that might be the problem, and try a different cable between the adapter and the projector.

It appears after calling Sanyo that the maximum output possible from the computer input is 1160 x 9??. I don't know why they selected that as the max when the native resolution is 1280 x 720. Anyway, the projected image defaults to the closest the projector will accept which is probably the 1024 x 760. There is no way around except for possibly trying to find someone with a laptop with a DVI output and DVI-HDMI cable.
I still can't figure out why the computer won't recognize the projector as being connect though.
Thanks for the help.
