Samsung mainstream 4K TVs offer true local dimming


Among the two 4K/UHD resolution LED LCD TVs we reviewed in 2013, the Samsung UNF9000 series was our favorite. The UNHU8500 is its closest match in the company's 2014 lineup.
It's available in a massive range of five sizes: 75, 65, 60, 55, and 50 inches. It arrives this April, and pricing has not been announced.
Among exotic sets like the curved HU9000 and exorbitant S9, the HU8500 is a sort of everyman's 4K resolution Samsung. Samsung says it has improved the upscaling to make 1080p and other non-4K content look better, and it also touts a color-improving thingy called "PurColor."
More important from a picture quality perspective in my book is the presence of the same kind of actual, hardware-based local dimming that helped make the UNF9000 one of the best-performing LED LCDs of last year. It's also worth noting that you can't get that kind of local dimming in a flat 1080p TV from Samsung this year; the only 1080p model to have it, the UNH8000 series, is curved.
Of course the HU8500 gets all the Smart TV bells and whistles, including a "Multi-Link Screen" that can divide the screen into two separate windows, each showing different content (live TV and YouTube, for example). It lacks the gesture control found on the step-up HU9000, but otherwise its Smart features are very similar. There's also the same promise of upgradability. While the HU8500 has a standard input array -- in contrast to the external One Connect box used on the F9000 and HU9000 -- it does include a port that can accept a future One Connect box to enable whatever upgrades, including, potentially, new input schemes, Samsung devises. For 2014 the set supports HEVC, HDMI 2.0, and HDCP 2.2.
