All the sets incorporate Toshiba's own CEVO 4K Quad-Dual Core Processor for accurate processing of both native and upscaled 4K content sources that includes a 240Hz screen refresh rate, built-in edge enhancement, and UltraClear Dynamic Noise Reduction.
Also, the sets provide, in addition to HDMI connectivity, built-in Wifi, Miracast, and WiDi wireless connection options for easy content access from both network/internet sources and compatible portable devices and PCs.
To provide further support, Toshiba has also announced the coming release of its new BDX6400 Technicolor-Certified Symbio Media Box/Blu-ray Disc player, which provides the best possible 4K upscaling for Blu-ray Disc and Internet/Network-based video content.
