Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
I believe our TV has only one HDMI connection. Can we use a splitter, and connect one HDMI cable to our DISH hopper, and the second HDMI cable to ROKU? We're not yet ready to "cut the cord", but want to get used to the ROKU, and be sure we want to switch.
Also, if we can use a splitter, do we need an A-B switch with it?
There's no such animal as a splitter that will allow two different devices to input into one display. But yes, there are HDMI switches that will allow you to do that. Some even have remotes so you don't have to be able to reach the switch. Or, you could use an AV receiver with HDMI switching.
