Problem MacBook and BenQ Projector

Hi everyone.

Hopefully someone can help me with this. I just bought a MacBook 2.0Ghz 2 Gig RAM and I tried to have it work with a BENQ PB2140 projector that I have. I used a mini-DVI to S-Video adapter (from Apple) to connect both, uisng the S-video port of the projector. Unfortunately, the screen always flicker, sometimes just a few lines at a times, sometimes much worst. I tried all resolutions and scan rates (50 and 60), etc. I just managed to make it work once, after much trial and error. Of course, upon restart (to make sure that I could duplicate my success) the problem came back and I was never able to fix it. As I wanted to use the MacBook (otherwise a stellar machine: my best notebook ever) to make presentations to clients on the road, I am a bit frustrated and could use some help here guys...Thanks in advance.

If you have used this projector with another computer before, is there any clue from those settings?

I have used the Apple adapter to run S-video into a high definition TV. As I recall, I bumped the resolution up from whatever it initially defaulted to (800 x 600?) to the highest it would allow (1024 x 768).

Is NTSC versus PAL an issue? That's on the Color tab in Display settings.

This doesn't answer the question about s-video, but does the projector have a VGA or DVI connector? You will get a higher resolution with one of those (and the appropriate mini-dvi connector).

Thanks for the reply. I know the BENQ works great with the S-Video port of a Toshiba Satellite A70 that I would like to sell to keep only the MacBook I will check into the NTSC and PAL thing but I think I already fiddled with that. Ans yes I believe that the highest resolution the BENQ takes is 1024 by 768.

Hi and thanks for your help. I will try a mini-DVI to VGA adapter. I did not know that the VGA port was higher resolution than the S-Video. The BENQ does not have a DVI connector.
