Epson Home Cinema 3010 3D Brightness
We've mentioned the Optoma HD33, as the other, similarly priced 2D/3D home projector. It too is a bright projector, but no match for the Epson Home Cinema 3010. The image below shows the Optoma on the left, Epson on the right. It's a huge difference in brightness. Of course, glasses and processing, also affects 3D brightness, but there is no contest at all. The Epson is dramatically brighter in 3D.
The two projectors are closer in brightness in their best 3D modes (a 3D image from Ultimate Wave 3D Tahiti). Again, the Epson is on the right.:
By comparison, 2D brightness is closer: Here are the two projectors again, this time in "best" 2D (the overexposure of the Epson is washing it out a bit):
