I was hoping the lighting would get better during the show, but nope. I'm all for keeping energy consumption down, but when it gives everything at the show a dingy pallor, it might be worth it to kick the brightness up a tad.
One of the cooler products I saw at the preview (and forgot to get a picture of, this is one of theirs), was the Mass Fidelity Core. It creates a convincing stereo effect from a single tiny box. A little pricey, but cool. Ty did a preview last week.
Dolby Atmos was the biggest thing at the show, with many companies offering Atmos-friendly in-ceiling speakers, upward-firing speakers, or like KEF, both. The R50, which sits on top of a normal tower speaker, is $1,199 a pair. The in-ceiling speakers range from $300 to $800.
Control 4, one of the big home automation companies, was showing off one of Sony's new "home automation friendly" TVs with Control 4's Simple Device Discovery Protocol (SDDP), which makes integration easier.
The new product from DVDO is actually the tiny little box on top of the TV. The Air3C is $190, and offers 1080p/60 wireless streaming. It's 60 Ghz, though, so it's basically line of sight (no cabinets, and you may lose signal if you walk in front of it).
Display Development does a great job hiding projectors so you can't see them. Here, a mirror folds down at the click of a button. The painting below slides down to reveal another projector (also hidden in the faux wall).
