Video of Sony's 84-inch 4K TV being demoed at CEDIA today. This thing is gorgeous...
You need to watch the high resolution version on Youtube to really see, though.
I posted some impressions of Sony's 4K display in a separate thread in case anyone wants to check it out... http://www.avsforum.com/t/1428193/4k-i-have-seen-the-light
Here is more info on Darbee's new product that I posted in this thread: http://www.avsforum.com/t/1428271/darbee-fidelio-demoed-at-cedia
We got a chance to check out Darbee's new higher-end image enhancing product for next year, the Fidelio, at CEDIA. Just like the Darblet, the Fidelio can vastly improve upon standard visuals (here are some high res examples if you want to see). While it's still a ways off -- a Darbee rep said it'll ship in Q3 of next year -- they had a prototype of it running at the show. As you can see, it's definitely for the higher-end consumer: it has a slick looking video equalizer, a touch-screen user interface, and it's wifi-enabled for downloadable features. Darbee says it'll likely retail in the $2,000 range.
