Re: Rogers Ignite box is telling me that my 4K tv is not 4K?
I am not an expert on 4K but speaking from experience this is what I have found. For me and the Samsung 4K tv I have , I had to go into the settings and turn on UHD for the HDMI port that i was connected to. Some tv's only had one HDMI port for 4K so just be aware of that too. Also if you are going through a Receiver or Soundbar first then back to TV, Those devices will also have to be 4K compatible. You may also want to use 4K compatible HDMI cables.
