buffered to death

The decor is almost self-explanatory and works quite well so far, the whole thing works unfortunately only with an associated (free) app, not with other Miracast Stream Apps. The app I find failed, for example, it summarizes all the videos on the smartphone in a folder, regardless of an existing folder structure.

I had constantly disconnects although I have placed the stick with a short HDMI extension before the TV. The distance was only 2 to 3 feet. When playing recorded with the Video Clips few MB are first buffered and then played. , All after a few seconds to play again from the beginning, but only a few seconds, then re-buffered, etc. Even leaving buffers with the pause function only once adequate catches.
