When playing (full) UHD movies, sometimes my tv went black for 2 seconds and then returns to the movie. This happens about 3 times in a movie. Is this a HDMI cable problem? Or something with the X9s? I use the standard shipped HDMI cable. The external HDD is the WD Elements 6TB, which is connected on the USB3 port. Do you guys have an idea what the problem can be? Greetings, Vinny
