The "W" in the name stands for "wallpaper," and this set certainly lives up to that moniker. Forbes found its 2.57-millimeter thickness incredible, noting that its slimness is such that it "changes the viewing experience, making you feel more like you’re looking out of a window than watching a TV." You can even bend the W7 to some extent, which doesn't do much except maybe impress your friends at parties.
But a flexible chassis isn't the only trick the W7 has to offer. Digital Trends found its OLED panel offers up "perfect blacks, excellent brightness and contrast, near-perfect color, and top-notch picture processing," good enough that they wanted to revisit favorite movies and upcoming UHD releases. They say it could be "the finest TV produced thus far in terms of picture quality" and Stuff agrees, saying it's the best you can currently buy.
However, the W7 is thin enough that it can't house its own speakers, outsourcing that function to an included soundbar. It does an admirable job, with Stuff noting it offers "crisp, clear audio with the sort of width and height that most TVs and a number of soundbars just can’t match." Unfortunately, it also "struggles quite a bit for bass weight and extension," and What Hi-Fi says "the speakers are really just scraping the surface." Digital Trends is "disappointed it creates virtual Atmos surround rather than delivering discreet Atmos surround information" and, while it delivers better performance than most out-of-the-box TV audio, TechRadar says "other Atmos soundbars do a better job."
With other LG OLED sets this year offering excellent picture, solid sound and the ease of webOS at a much lower price there's really no reason to buy a W7... unless you really need a statement piece to tie together your living room.
