Problem connecting MacBook to a Sharp video projector

One of the great things I like about Macs is the easy way they (usually) connect to a video projector. Unlike a lot of my friends who run PCs with Windows I never had any problems whatsoever connecting my MacBook to a projector at the university and start my presentations.
Until today that is.
I tried to connect my MacBook with Apple's mini-DVI to VGA adapter to a Sharp ("Notevision") video projector and although the MacBook had the projector (even with its correct name "PG-M20X" and available resolution settings) listed under "Displays" immediately, I couldn't get the projector to show any more than "no signal" whatever input source I chose...
What did I do wrong? Or is it the projector that is somehow "incompatible"?! Please help!

Hi, welcome to macbook forum,

first, check if your macbook magsafe is plugged, and then check if the vga cable is connected properly.

Try to connect everything and restart your macbook.

Maybe reset PRAM and SMC might needed to refresh your macbook hardware behaviour:

I did a PRAM reset lately, because my MacBook didn't go to sleep when the battery was empty in the last days (will contact Apple because of that soon)I tried a couple of restarts not only for the MacBook but also for the video projector...whatever I did, nothing made the projector showing a video from my MacBook.

Maybe this could help as well:

After we tried several things with the MacBook (reboot, "detect displays" etc.), we successfully connected a Powerbook (15", FireWire 800, late 2003) to the projector, using Apple's DVI-VGA Adapter.
So that did work out fine, but the MacBook didn't work on the projector. The cable that came with the projector was a VGA--DVI-A cable: there were only a few pins on the DVI-end of it going into the DVI-Connector on the projector. Could it have something to do with that? But why didn't the Powerbook have any problems connecting to the projector then?

Any news on this issue?

When you manage to connect using Powerbook, do open system preference and make a note of what resolution and Refresh Rate that appears there.

And retry to set up using your macbook and start with the lowest refresh rate and resolution like 60 Hertz and 640 x 480. etc.

Good Luck.
