Jon,
I went to the app store on my Chromebook and "downloaded" the Netflix onto Chromebook. So I then clicked on app icon and then clicked on Netflix. Signed in to Neflix, then clicked on the Google cast tab in the upper right hand corner of screen. It seemed doing it this way the screen on the TV was a bit fuzzy, not crisp and would be a bit choppy, but doable. Later I just streamed Netflix onto my screen of the Chromebook, and it was crisper and not choppy, better quality.
I casted You tube onto big screen TV from the same Chromebook the other day and it was just fine.
