Samsung also improved its single cable solution on its Q7F and Q9F models. Just like last year, it's a single optical fiber wire that connects to a separate box that houses all of your typical inputs. This time, though, that cable also carries power. Samsung had to make it a bit thicker to make that happen, but it seems like a worthy trade-off. Having to run power separately kind of defeated the purpose of the company's single-cable vision. The TVs come with a 5 meter cable, but you can also order a 15 meter version separately.

As you'd expect, Samsung is also making the QLED TVs smarter with Bixby integration. It replaces S-Voice, the company's middling voice interface, and lets you search for content across TV and streaming services (no Netflix yet, though). Bixby isn't as advanced as its mobile sibling, but it's a first step towards unifying the company's platforms. With SmartThings support, you'll also be able to control compatible smart devices right from your TV. That's especially useful for things like smart cameras, since they can show up on your screen.
