What is 4K+? How does it work with preexisting Roku accounts?
I have a Roku built into my tv I purchased, it’s supposed to be 4K but I bout it maybe 5 or so years ago, I been seeing this 4K+ upgrade thing. 1, what does it do precisely? 2, if I buy the 4K attachment for it will it still work? Being that I have a Roku built in. My tv only runs on Roku.
