I bought this adapter before I found your forum asix ax88179 thread https://www.amazon.fr/gp/product/B00MYTSN18/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
It works and can play 4K video files without continuous buffer updates. But when I turn my LG Oled55B9 off and on again the connection is lost. If I activate Wifi, it is he who takes control (bad). It doesn't take much for this to work. But for now it is not usable.
