Ok so I am a little confuse about the hopper output. My vizio 4k tv only allows 4K 60 fps on hdmi 5. On hdmi 1 & 2 it is 30 fps. If I hook the hopper up to the 30 fps port, it only shows 1080I as the resolution on the 4K channel. If I switch it to hdmi 5 it show up as 2160p on the 4K channel. I am using an hdmi 1.4 cable, which is only supposed to support up to 30 fps on 4K. So how is it possible to show 60 fps on port 5 with an hdmi 1.4 cable? I also noticed that on port 5 the upscalling for the 1080 channels is not there, or not as good as on a 30 fps port. Why will my tv not work with the hopper on a 30 fps input to show 4K?
