The Sony X900E was a sleeper hit last year, offering a FALD (full-array local dimming) backlight in a mid-priced LCD TV. At CES 2018, the company unveiled the next-generation Sony X900F.

Like its predecessor, the Sony X900F incorporates a FALD backlight. However, its video processor has been upgraded to the X1 Extreme, which allows it to support Dolby Vision high dynamic range as well as HDR10 and HLG. Also, a new technology called X-Motion Clarity is said to keep fast action images smooth and life-like using Sony's proprietary local-dimming algorithm to control the luminance and duration of each dimming zone.The X1 Extreme also employs three technologies—Object-Based HDR Remastering, Super Bit Mapping 4K HDR, and Dual-Database Processing—as well as 4K Reality Pro, to render the best possible image from any source. Another feature called X-tended Dynamic Range Pro is said to enhance HDR and non-HDR content by boosting and dimming backlight levels for each dimming zone.As an Android TV, the Sony X900F includes lots of streaming apps. It also provides Google Assistant built-in, which lets you find content simply by talking. In addition, you can control the TV with Amazon Alexa-enabled devices and Google Home. For example, you can ask Alexa to play, pause, fast forward, and rewind.According to Mike Fasulo, President and COO of Sony Electronics, North America, "Our OLED TVs have been extremely well received by bringing exceptional picture and sound quality together, and the X900E has been amongst our most popular LED TVs. Building on the great successes of the X900 and OLED TV series, we are further expanding the choices for consumers by introducing the new X900F LED and A8F OLED TV models."The Sony X900F will be available in a wider range of sizes than last year, including 49", 55", 65", 75", and 85". The big story here is the bump up in processor power, which supports Dolby Vision among other things. Pricing and availability have not yet been disclosed.
