Yea I don't have any 4k content really, aside from what I've seen on a few youtube clips. The upscaling is so-so.
The 4k netflix is another $4/mo extra, not worth it to me just yet.
That tv looks pretty similar to mine. I'm not looking at using my for a gaming monitor like a lot of people. As far as the smart tv features I've been pretty happy. I plugged in a usb3 harddrive with movies and whatnot on it. The nice thing is that if you watch an episode of something, it just starts playing the next one in the folder after it's done. The downside, it made me waste 2 hours of my morning watching old batman cartoons. Apparently, you can get a usb camera and skype with your tv or use the camera for motion gestures.
The PC app, Smart View, looks pretty cool. Synced it to my tv and and now I can watch tv on my computer. Downside there is, it simply mirrors, so no split tuning. Still, nice when you got the OSU game on (even though they're losing)
