The big thing is allowing you to move content, including streaming content, from your PC to your TV. Smart TVs are still heavily limited on their ability to stream content, mostly relying on app written for specific sources (Netflix, HBOGo, Amazon). Some have browsers but their browsers tend to stink, so if there’s some streaming content on nbc.com you want to see you probably have to see it on you computer, because your TV either can’t get to it or can’t understand it. Enter DLNA and/ or the Chrome thingy: bring up the video on your computer, share it with yourself, stream it to your TV. Also handy for non-stream stuff on your computer, though if you’ve got USB on your TV sneakernet will still probably be easier on that front.
I see. Yes, this is improved over what I have. I can watch youtube seamlessly on my TV but I am limited as to what else I can stream.
Yeah real hard to do. Its called an HDMI cable and you hook your computer up as a monitor. Wally World has em for about 12 bucks.
