Sure, it supports 4K resolutions, but when a TV measures 77 — or even 65 — inches diagonally, it's going to draw a lot of attention whether it's on or off. Luckily, the new ultra-slim LG G6 OLED TV looks great either way. Thanks to a Picture-On-Glass design, it measures just 2.57mm thick, not including the integrated sound bar speaker system from harman/kardon. The set's OLED and ColorPrime Pro technologies let it take full advantage of the new HDR standard, and the webOS 3.0-powered smart interface is among the nicest built into any TV on the market.
Odds are you've seen an HDR photo, so you know what the added range can do for an image. Now imagine that image as a video in 4K resolution, and you've got an idea of what to expect from the Vizio Reference Series TV. The 65-inch set is the first on the market to Dolby Vision, using quantum dots and other cutting-edge tech to deliver a picture far beyond that of any common set, with over one billion possible colors. It's powered by a six-core processor, supports both 4K and HDR streaming content, and has a built-in 3-channel sound bar, paired with an included wireless 10-inch subwoofer and satellite speakers for out-of-the-box 5.1 surround sound. Also available in a staggeringly large, $130,000 120-inch model.
With access to more 4K content than any other streaming box, the Roku 4 makes a strong case for taking up an HDMI port on your UHD set. Its quad-core processor and 802.11ac Wi-Fi let it support 4K streams at up to 60 fps, and a dedicated 4K spotlight section makes it easy to find high-res content from Amazon, Netflix, Vudu, and YouTube. Its remote lets you search for shows and movies using nothing but your voice and has a headphone jack for private listening, and the box has a dedicated button for helping you find it when it's slipped down between the cushions on your couch.
