This is possible because OLED technology doesn’t require the same backlighting as LCD sets. You can’t put this TV on a stand on some table; the only honorable option is to mount it to the wall.
LG has nonetheless made slight improvements to image quality across its 2017 OLED lineup, which includes the B7, C7, E7, G7, and the W7 featured here.The main upgrade is that they’re capable of getting brighter “where needed” in certain scenes. They all support every flavor of HDR video, as well: HDR10, Dolby Vision, and HLG (Hybrid Log Gamma). Technicolor apparently lended some “color science expertise” related to calibration and reproduction technologies to LG in the making of these sets, as well.
WebOS continues to be the underlying software platform on these TVs and, now at version 3.5 on LG TVs, is mostly unchanged from 2016; it remains very colorful and probably the most “fun” TV interface from the major brands, but that by no means makes it the best. I’m sure there will be people wishing these TVs ran Android TV or Chromecast instead. LG says it has “partnered” with Netflix, Amazon Video, and Vudu this year, likely just to give 4K and HDR content more prominent placement in the interface.
LG isn’t revealing final pricing for its new signature 4K OLED yet. Probably more expensive than any consumer line you’ll see at CES from competitors like Samsung and Sony.
Prototypes of this “wallpaper” display actually curled at the edges, but LG advises against trying that with the shipping consumer display. Speaking of which, the 65-inch Signature OLED W will start shipping in February and arrive in stores by March. A handful of Best Buy stores will also be showcasing the TV and taking preorders starting January 5th.
