MOOC’s (Massive Open Online Courses) are an excellent way to enhance your career or to explore subjects you missed in your school days. You can watch MOOC lectures from sites like Coursera, Udacity, or edX on your computer, your tablet, or even your phone, but for an even better experience, you can cast them to your big-screen TV.
I have a Roku 3 and a Galaxy S6 Edge. When I first tried to cast from my phone to my Roku a few years ago, both video and audio were extremely laggy.
Recently, I tried again with the Android Smart View feature, and the results are much better. Games are still laggy, but Coursera videos play smoothly. The only problem I noticed was audio skipping occasionally. However, when I turned off my sound bar and used the TV’s own sound instead, the audio was fine. I don’t really need extra bass for a deep learning lecture.
Of course, if you have a Chromecast, you can just use the Chromecast for your own private lecture hall.
