Re: Projector for spherical mirror projection?
- Hi everyone, I'm really looking for a cheaper alternative that I could use for a mirror projection. Any advice?

Note that while resolution is certainly important and I don't recommend anything less than HD or WUXGA for the spherical mirror, there are other considerations. For example in my last reply I mentioned the DELL and the Optoma, in reality the Optoma has MUCH better colour capabilities than the DELL, enough to easily negate the marginal difference in resolution. Brightness is also important, all the models you listed I would consider to give a very low brightness image on a 8m dome.
You might also consider looking at LCoS projectors to avoid the screen door effect and, on the good models, much better black.
