iPad VGA projected image offset and cut off

I bought an iPad VGA cable last night and hooked it up to my Optoma PT-100 projector (cheap kiddie projector, 854x480 resolution).

I tried slideshow and the pictures were horizontally stretched. Bummer.

Then I tried netflix and I noticed a far more serious problem - the screen is offset to the right and the right quarter of the screen is cut off. The left quarter is totally black.

There's no settings anywhere for this thing so I wasn't really sure what to do / how to fix?

I have not tried hooking it up to a different monitor yet.

See if there are resolution or size setting on the projector, and scroll thru them until you get the right size/ aspect for what the pad is sending. I dont think you can adjustnthe putput format from the pad, so you have to do it on the projector. There is usually a setting somewhere.

So half of it was just the projector not doing a very good job of resetting itself. That was the shift and the right quarter being cut off. All I needed to do there was power it off and on again and it resets the image.

The other part is really frustrating. This is where your answer did help. For some odd reason, the VGA cable is giving a 4:3 image to my projector which I don't get at all. But changing that setting in the projector did help. This is especially weird because when I tested it on my tv it put out a 16:9 image.

I think if I play with the Netflix screen modes setting I might be able to get a full 16:9 image. What's frustrating about apple's "it just works" philosophy is when it doesn't and there's no way to try and workaround the issue.

Glad you got it going. I have never seen any two projectors that worked exactly the same. I think the only consistancy is that they all need to be messed with to get them to work right.
