4K streaming failure on Roku4

when attempting to switch my Roku4 to 4K resolution, I am getting a message informing me that my HDMI connection will not support 4K.   Is this an issue with my newer Samsung UHD tv or with the older Roku?

Re: 4K streaming failure on Roku4

What's the model number of the TV?  Some only support 4k on certain HDMI inputs and you need a cable that's up to the task.
