UltraFlix has just released their new app for the Amazon Fire TV. The service claims to have the worlds largest library of streaming 4K Ultra HD content. Their content library consists of native digital 4K titles, which they label as “Platinum” titles, film scanned in 4K, which are labeled “Gold”, and 1080p movies upconverted to 4K, which are given a “Silver” designation. Currently, the service only offers rentals, but plans to offer purchases and is considering a Netflix-style subscription model. Rental prices range from $1.99 to $9.99. Purchased content will range from $9.99 to $24.99. The app is only available on the new 4K capable 2nd-generation Fire TV.
It appears UltraFlix does not correctly switch into 2160p resolution when playing 4K content. This means, until the app gets fixed, it only outputs in 1080p. Thanks Vulcan195 for the heads up!
