Q. My brother has an extra Roku streaming box that he wants to give me. But it’s a Ultra box which is a 4K one. My question is will it work on our High-Definition TV even though it’s a 4K box? Is there anything special we have to do to make it work? — Shelley, Reno, Nevada.
Shelley, you’re right. The Roku 4K Ultra streaming device can display 4K programming on a 4K TV, but it will work with any TV that has an HDMI connection, including older high-def models. (In fact, any Roku device that’s 4K-enabled will work on a HDTV.)
However, note that it will not show any programming in 4K on your HDTV. For that, you would need to buy a 4K TV and connect the Ultra to it rather than your current high-def TV.
Roku says a successful Ultra to HDTV connection will also require a high-speed HDMI cable unless you are connecting a Roku Streaming Stick+ to the set. (The Streaming Stick+ also can display 4K programming on a 4K TV.)
You can purchase a high-speed HDMI cable for less than $20, and I will post a few here in Amazon product ads for your convenience.
So Shelley, tell your bro to send that Roku Ultra over because it will perform without an issue.

None at all? It won’t downscale it to work on the HDTV?
I thought that all ROKUs had resolution settings you can choose to match the TV you have.
