No video pause, no video tearing. To me, it plays smoothly like on the mobile phone.

This hint really helped me a lot! I have the problem that my phone has a 2:1 (resp. 16:8) screen ratio instead of standard fullHD 16:9. So I get 1/18 black bars top and bottom. This is not too annoying while surfing or writing on my phone but for videos it is. Especially when I watch a 16:9 video "fullscreen" on my phone as it adds black bars on the left and right side. So when streaming directly from the web browser on the phone a video "fullscreen", I am getting black bars all around the video.

BUT as you mentioned VLC is able to directly access the displaylink hardware. With the Firefox extension "External Video Player" I can easily play my video with VLC instead of Firefox itself and voila: I am getting fullHD streaming without any black bars from my phone to my external monitor. Awesome!
