Samsung this week formally introduced its 2019 Ultra-HD TV family. The new high-end televisions from Samsung all feature QLED backlighting and compared to their 2018 predecessors, have received audio and video quality enhancements. Select models will also get AMD’s FreeSync variable refresh rate tech along with Samsung's Game Motion Plus tech to remove blur and judder in fast-paced scenes. Finally, along with the new hardware, all of the new Smart TVs (as well as those launched in 2018) will receive the iTunes Movies & TV Shows app and Apple AirPlay 2 support (as reported), along with the new Universal Guide that is designed to allow users to discover content more quickly.
Samsung Q900: 8K King of the Hill

Samsung’s Q900 series will remain the company’s top-of-the-range lineup, offering an 8K (7680×4320) resolution and coming in 65, 75, 82, 85, and 98-inch sizes. This year’s Samsung Q900-series televisions will be based on a version of the Quantum Processor 8K (briefly described last year) that not only upscales content to an 8K res, but optimizes “audio and video to the specific content” as well as tailors audio settings for the particular environment.
Samsung QLED 4K: Premium UHD TVs Get Better

At the 4K level, Samsung’s premium Q90 and Q80 lineups of 4K Ultra-HD TVs will get new panels, which are said to feature wider viewing angles (which the maker does not quantify), less glare, and better color reproduction. The latter would appear to be courtesy of a revamped backlighting system featuring quantum dots, as well as precision-controlled LEDs to enhance contrasts, which along with the Q90 and Q80 series TVs, will also be coming to the Q70 series.

Meanwhile, starting with this year's models, Samsung’s QLED 4K TVs will be powered by the Quantum Processor 4K that upscales content to a 3840×2160 resolution and enhances its quality through various other algorithms.
