I've had the TV for a week, after purchasing the 55" version a couple of weeks earlier. The 65" version also lives up to my expectations. I used an existing wall mount which worked well (not all do). If I move the TV to another location, I'll use the included wall mount, which is necessary to achieve that super-flush-to-the-wall look. The self-help videos provided by LG are workable, but I suggest searching YouTube videos for greater detail if needed.
The routing of cables could use channels that exit the TV in other places, perhaps via the sides or even the top. It seems that the only way to use the otherwise excellent routing system is to create a visibility issue when cables leave the bottom of the TV. That of course can be avoided by cutting into a wall near the existing LG cable routing, though cable routing there requires taking care to be precise in order to meet the channeling on the back of the TV. Related to this: I would have preferred the option to use a shorter, detachable power cable instead of being forced to stick to the longer and fixed power cable, but I understand that most users probably find the length useful whether using external cable management or in-wall concealment. I didn't have that option because I installed the TV up against a brick wall that's behind plaster—that would have been a messy effort to create something approaching an in-wall cabling solution. I was therefore forced to route cables more than once using LG's cabling locks.
One of the third-party YouTube videos suggested using Cinema mode instead of filmmaker mode for the screen. I've tried both and the difference is not dramatic, but a bit brighter look on darker images does happen in cinema mode. I like how easy it is to change this setting at any time. And that leads to a more general point about the relative ease of changing settings. In general, making changes to the system is easier than I've found on other TVs that I have owned. Still, there is a learning curve, and I continue to discover more features I can manipulate if I'd like. As I said at the beginning, I'm still quite new to the TV.
WebOS is one of the better interfaces out there. I found that I needed to edit LG channels and live TV channels to reduce the amount of scrolling. What really helps is the ability to screen out genres when adding channels or afterward. The only interface that beats WebOS in my experience is the Apple TV box. I move back and forth between both interfaces. It is here that the LG shines: it is a seamless transition from within LG's WebOS interface. If I prefer to use the Apple TV when firing up the TV, eArc works well for that; but even then, it's easy, using the LG remote home button, to immediately be presented with the WebOS. No glitches so far, unlike other brands that are relatively clunky, requiring reboots at times.
Native sound is fine for me. However, I use my receiver eArc-ed, which works well.
Overall, I expect to stay satisfied with LG's G3 series.
