The basic Roku link code from TV setup instructions for most of the Roku models are generally the same that can be activated through Roku Link Account. All the Roku models are not available in all the countries; some streaming Roku players support 4K HDR. You should also possess a TV that is compatible with 4K high definition resolution. The only similarities are that you can connect all the Roku players through the HDMI port of your TV. For more details contact @ +1-888-269-1011 to get rid of your issues.
