A:Answer I just got this TV a couple weeks ago and the picture quality is great. I was also impressed with ease of setup, for instance if you have a Samsung phone it has you download the app then once you do that and open the app up you go through the setup of the TV and it sets up the Wifi and everything else in a matter of moments it's really amazing how easy it is to get that done, so you don't need a Wifi adapter it's all built in. The only thing I'm not sure on is the Roku, I know it has something of a DVR but I haven't really played with that part of it. It has so many apps on the TV that if you can't find something to watch that's crazy. All in all great TV and I would recommend purchasing it.
