Hi Guys,  I wanted to watch some of my videos that I have on my 7.85 UB Crystal Sky on my 4 K tv.. I pluged an HDMI cable into the HDMI out on the CS and the other end into the HDMI in on my tv.  I started the video on the CS but got nothimg on my tv.  Does anybody have any ideas what I'm doing wrong.  Thanks

Well in most cases you have the wrong input enabled on your TV or you are trying to use a standard HDMI cable which is crap with 4k if it even works at all
