I recently purchased an L6_H, which I believe is a China Only Model, while I'm living in Qingdao. I have tried to connect it wirelessly to my Surface Pro 4 but my Surface does not recognize it as a display. It does see it as an external Blutooth audio device, but the projector does not produce sound when it's selected as the default audio output. I thought both devices were Miracast compatible. Is there something I'm doing wrong?
Thank you for your help!

We are not familiar with the L6_H however, unless you are in different wifi bands, it sounds like you are doing everything correctly.  Bluetooth should work either way.
