I finally bought the Minix U1, my question relates to the HDMI cable, since what is included in the box is too short for what I need, I want to purchase a replacement. My question is there is an HDMI 1.4 two meters that I saw being sold and I'm afraid that that version is not compatible or would affect playablity of some files (h.265 video movies), is it really required to purchase an HDMI 2.0 cable? Where can I buy such cable?
