Isn't there a chance of the bulb exploding if it has too many hours on it?

Re: DLP Rainbow effect demonstrated

I see rainbows when I watch the credits at the begining/ending of a program. Usually during a movie I won't though. It does look fairly close to the example. Depending on the color wheel colors the rainbow will change.

Also if I'm watching a black and white movie and someone has a suit that is a fine plaid, I'll also the pattern with a pinkish green hue. Drives me nutts.

Re: DLP Rainbow effect demonstrated

The easiest way to avoid the rainbow effect with a DLP projector is to use a non-reflective screen.

I've been using a Dell 3100 MP XGA DLP projector sold by Dell as a presentation box - the 3100MP - for six years. In my 15' square theater, it throws an image 7' wide by 5'3" high. It handles whatever format it gets through its component cable (which plugs into a DVI jack) - I feed it 480p SD DVD from my Denon 2910, 720p or 1080i from the HD cable box, and - into its S-Video port - fuzzy 480i from my Mitsubishi VHS-HiFi deck (but only under duress!).

With my first screen, highly-reflective drymount board, I saw rainbows frequently.

Within weeks, I switched to the bare wall, spackled smooth and painted with flat white household paint from the hardware store, and haven't seen a rainbow since.

For extra snazziness, thick black cardboard ("chipboard" from an artists supply store) on the wall hides the gray frame the projector puts around the image, since black lit up by dim gray is still black!
