text: It works well without any setup, just plug and play. The only thing I don't like, at least with my laptop, is that it makes the laptop screen black when I cast to the tv. I can still use the touchpad or even the touch screen on my laptop, but can only see the screen on the tv. I'm not sure if this is a setting that can be changed on my laptop, but when I used to cast from my laptop to a roku, I was able to see the screen on both the laptop and tv.
