When you have a 2.35 screen, you zoom your projector all the way out to fill the screen. Obviously you'll have a large amount of the picture hanging off the top and bottom of the screen. But when you set up your Lumagen for CIH (there are instructions on their website for this), you'll normally be in 16:9 mode on the Lumagen which will actually display a 16:9 picture on your 2.35 screen. It's not distorted or anything like that. If you have 2.35 material (Lord of the Rings, Star Wars, etc.) you'll of course have black bars on the sides of the screen and now on the top and bottom resulting in a very small picture. If you push the 2.35 button on the Lumagen remote, it then fills the entire screen with the picture. It's perfect every time with no part of the picture hanging off the side of the screen like with lens zooming. If you want 16:9 material to fill the 2.35 screen, then you push the NLS button on the remote, and it stretches the image to fill the 2.35 screen. It's a hell of a feature. You can basically watch everything in 2.35. Go to youtube and search for Brolicbeast media and see if you can find his video demonstrating what the Lumagen can do for a CIH setup.
