    What is the Sony KD-55XD8577?

    The KD-55XD8577 is Sony's mid-range 4K TV for 2016 and features Ultra HD resolution as well as support for High Dynamic Range (HDR). There are three other screen sizes in this range, the 65-inch 65XD8577, the 75-inch 75XD8505 and the 85-inch 85XD8505. Aside from the differing screen sizes, the only other differences between the models are that the 55- and 65-inch versions use 1000Hz Motion Flow and the 75- and 85-inch models use 800Hz Motion Flow. All the screen sizes incorporates the X1 4K processor with X-Reality Pro, uses a Triluminos panel, has a Dynamic Contrast Enhancer and come with Android TV platform with YouView integrated.

    This is a preview of the upcoming KD-55XD8577 model and will be replaced with the full in-depth review as soon as we have measured and reviewed the final retail sample. In the meantime here is a rundown of the features we can expect to see.

    XD85 Picture Quality Features

    As per the majority of Sony TVs in 2016, the KD-55XD8577 is HDR compatible and, although edge-lit, the new model includes a Dynamic Contrast Enhancer. There’s also an expanded colour gamut thanks to the use of a TRILUMINOS panel - i.e. quantum dot - which has been further enhanced for colour accuracy. The 4K X-Reality Pro chip uses a unique algorithm from a reality creation database for TV broadcasting, DVD, Blu-ray Disc, Internet video and digital still photos to improve scaling and interpolation. The 4K Processor X1 is a technology that uses algorithms to cut noise and boost detail; it works with 4K X-Reality Pro to produce pictures that Sony claims to be, ‘sharp, clear and incredibly lifelike.’

    Smart TV and Other Specs

    The XD85 range uses a slim crafted aluminium design with a super slim body and thin aluminium bezel that makes it ideal for wall mounting. The flat panel uses edge LED backlighting and sits on an angled silver stand. The 2016 Sony Smart TVs will once again run of the Android TV platform which allows you to send movies and music from your smartphone to your TV with Google Cast; you can also find things to watch, whether broadcast or via the internet, using the content bar or voice search and there’s games streaming via PlayStation Now - and Google Play - as well as integrated catch-up TV services, thanks to the inclusion of the YouView platform.
