Hello, i got my X9S yesterday and this is my first post in the forum. my zidoo is connected to an Acer M550 4k HDR projector with a 10 meter (33 feet) long HDMI. the zidoo native player (and also internal ZDMC player) plays 4k HDR files like Full UHD blurays or remuxes or rips, but occasionally the signal drops and resyncs (sometimes it doesn't sync back). also, during the playback of these files i get horizontal thin lines flickers all around the screen (very annoying). all other content works fine. i need to know if this is a cable+zidoo interaction problem or only a zidoo issue. i tested the same cable and content with an nvidia Shield streamer and everything runs smooth without any dropouts, so i guess the cable itself is working properly. ALSO - when using the short 1 meter cable that came in the box with the zidoo - does not pass 4k signal to the projector at all! only 1080p. but with the nvidia shield it also works perfectly at all resolutions. so does the zidoo x9s send very weak signal and i need to search for a cable or is my specific unit defected?
