4K pvr not dispalying in 4K on my samsung 55 inch uhd tv anymore. It is displaying in 1080p instead. It was in 4K a couple of weeks ago. I have reset the box. Cycled the power. And the HDMI cable is good as well. Any ideas?

I had the same problem with cheap Hdmi cables on my Xbox s(when I went to a friend's house and forgot my hdmi cable), you need good cables for 4k PVR,1080p cables won't cut it, I would try good set of hdmi cables, all I use is monster hdmi cables in my house and never have any problems anymore.
