Well, I just ordered a Lumis 3d-Solo.
I will be upgrading from my C3X 1080. I demo'd the unit a few days ago at Sim2. Very nice. Beautiful 3D images on their 11 foot wide (2.35:1) screen. Plenty bright without any artifacts. The DirecTv images looked the same, even with the lower refresh rate.
When you feed it a 3D signal, the projector automatically increases the brightness. No settings to change.
The batch they just received all have Dynamic Black for 2D. They also have a proprietary IR emitter system made for them by Xpand, which has a curvy box to match the projector. Not that it matters, as you can place the box out of sight. The glasses are also badged with Sim2 logo.
I'll post a review when I get it installed (about 2-3 wks). My C3x1080 will be for sale if anyone is interested (in excellent condition).
