This 55-inch smart TV from LG is absolutely on the cutting edge. It features a curved display, stereoscopic 3D support, a webOS-based operating system, and all the apps you could ever want. But the best part of this TV has to be the incredible 55-inch display itself. It's 0.17-inches thin, offers a 240Hz refresh rate, a full 1080p resolution, and it's among the first affordable consumer-grade OLED televisions.
