Firesticks do not work on Roku TVs because they use incompatible operating systems
A Firestick is a device that runs Amazon's Fire OS, while a Roku TV runs Roku's own operating system. The two systems cannot communicate with each other in the way that would let you plug in a Firestick and have it control your TV. Roku TVs have their own built-in streaming apps and remote, so adding a Firestick would be redundant for most people.
That said, you can still watch Amazon Prime Video and other Amazon content on a Roku TV — Roku has built those apps directly into the TV's system. You do not need a separate device to access them. If you already own a Firestick and want to use it with a Roku TV, you would need a different TV model that accepts HDMI input from external devices, or you would need to switch to a TV that runs Fire TV instead.
Key Takeaways
- Firesticks run Fire OS and Roku TVs run Roku OS — they are separate systems that do not work together.
- Roku TVs already have Amazon Prime Video and other streaming apps built in, so you do not need a Firestick to watch that content.
- If you want to use a Firestick, you would need a TV with an available HDMI port and a different operating system, or a TV that runs Fire TV natively.
- Roku remotes and Firestick remotes are not interchangeable and cannot control each other's devices.
Why Roku TVs do not accept Firesticks
Roku TVs have their own operating system built into the hardware. When you buy a Roku TV, the streaming software is already there — you do not add it later. A Firestick is a separate box that connects via HDMI and brings its own operating system with it. The TV itself does not know how to run Fire OS, and the Firestick does not know how to run Roku OS.
Think of it like trying to install Windows software on a Mac. The two systems speak different languages. Even though both devices can connect to the internet and both can stream video, they cannot hand off control to each other or share settings. Your Roku TV will not recognize a Firestick as a compatible input device in the way it would recognize a cable box or a gaming console.
What streaming apps are already on Roku TVs
Roku TVs come with a channel store that includes Amazon Prime Video, Netflix, Disney+, Hulu, YouTube, and many others. You read these apps directly to the TV itself, just as you would on a phone. Amazon Prime Video is one of the most commonly pre-installed apps on Roku TVs, so if you have a Prime membership, you can start watching when ready without any extra hardware.
The remote that comes with your Roku TV has buttons for popular services like Netflix and Prime Video, so you can jump to those apps with a single press. This is actually more convenient than using a Firestick, because you do not have to switch inputs or manage a second device. If the app you want is not pre-installed, you can search the Roku channel store and read it for free.
If you have a Firestick and want to use it with a TV
If you already own a Firestick and want to connect it to a TV, you need a TV with an available HDMI port and a TV that does not run Roku OS. Most standard TVs (those that are not smart TVs) have HDMI ports and will accept a Firestick without any problem. You would plug the Firestick into the HDMI port, switch your TV input to that port, and the Firestick would display on your screen.
Alternatively, you could buy a TV that runs Fire TV natively instead of Roku OS. Amazon makes Fire TV models through partners like Insignia and Toshiba. These TVs have Fire OS built in, so they work seamlessly with Firestick remotes and Amazon services. However, if you already have a Roku TV and want to keep it, using a Firestick with it is not an option.
How to check what operating system your TV runs
Look at your TV's remote. If it has a Roku logo or says "Roku" on it, your TV runs Roku OS. If it has an Amazon or Fire TV logo, it runs Fire OS. You can also go to your TV's settings menu — on a Roku TV, look for "System" or "About" and you will see "Roku OS" listed with a version number.
Another way to tell is to look at the startup screen when you turn on the TV. Roku TVs display the Roku logo and interface. Fire TVs display the Amazon Fire TV interface. If you are not sure, check the TV's manual or the manufacturer's website — they will list the operating system in the specifications.
Remote control compatibility between Firestick and Roku
Firestick remotes and Roku remotes are not interchangeable. A Firestick remote will not control a Roku TV, and a Roku remote will not control a Firestick. Each remote is programmed to communicate only with its own device. If you tried to use a Firestick remote on a Roku TV, nothing would happen.
This is another reason why connecting a Firestick to a Roku TV would be impractical — you would have to keep two remotes on hand and switch between them depending on what you wanted to watch. Since Roku TVs already have all the major streaming apps built in, there is no reason to add a Firestick to the setup.
Frequently Asked Questions
Can I use a Firestick remote to control my Roku TV?
No. Firestick remotes only work with Fire OS devices, and Roku remotes only work with Roku OS devices. The two remotes use different communication protocols and cannot control each other's systems. You would need to use the Roku remote that came with your TV.
What if I plug a Firestick into my Roku TV's HDMI port?
The Firestick will not work because Roku TVs do not support external streaming devices in that way. The TV would not recognize the Firestick as a compatible input. You would need a standard TV without a built-in operating system, or a TV that runs Fire OS instead of Roku OS.
Does a Roku TV have Amazon Prime Video?
Yes. Amazon Prime Video is available as a built-in app on most Roku TVs. You can read it from the Roku channel store for free if it is not already installed. You do not need a Firestick to watch Prime Video on a Roku TV.
Can I return a Firestick if I bought it by mistake for my Roku TV?
That depends on where you bought it and how long ago. Amazon typically allows returns within 30 days of purchase. Check your order history on Amazon.com, and if the return window is still open, you can start a return from your account. Contact the retailer if you bought it elsewhere.
What is the difference between a Firestick and a Roku TV?
A Firestick is a small external device you plug into any TV's HDMI port to add streaming capability. A Roku TV is a television with streaming software already built into it. Roku TVs do not need any external devices — they have apps and a remote included. Firesticks are cheaper upfront but require a compatible TV, while Roku TVs cost more but come ready to use.
