Fire Stick will not work on a Roku TV because they use different operating systems

A Fire Stick runs Amazon's Fire OS, while Roku TVs run Roku OS. The two systems do not communicate with each other, and Amazon does not make Fire Stick software for Roku's platform. You cannot install Fire Stick on a Roku TV, and you cannot use a Fire Stick remote to control a Roku TV's main functions.

However, you do have options if you want Fire Stick features on your Roku TV. You can connect a Fire Stick to your Roku TV using an HDMI port, just as you would with any other TV. The Fire Stick will appear as an input source, and you can switch between Roku's built-in apps and the Fire Stick's apps by changing inputs.

The trade-off is that you will be running two separate systems on one TV. Your Roku remote controls the TV and Roku apps. Your Fire Stick remote controls Fire Stick apps and services. You cannot use one remote for both.

Key Takeaways

  • Fire Stick and Roku TV use different operating systems and cannot be merged into one system.
  • You can plug a Fire Stick into your Roku TV's HDMI port and switch between the two systems using your TV's input button.
  • You will need two remotes: one for Roku and one for Fire Stick, unless you buy a universal remote that supports both.
  • If your Roku TV already has the apps you want (Netflix, Prime Video, Disney+), you may not need a Fire Stick at all.

What happens when you connect a Fire Stick to a Roku TV

Connecting a Fire Stick to a Roku TV is straightforward. Plug the Fire Stick into any available HDMI port on the back or side of your TV. Plug the Fire Stick's power adapter into an outlet. Turn on the TV and use the input or source button on your Roku remote to select the HDMI port where the Fire Stick is connected.

Once you switch to that input, the Fire Stick's home screen appears, and you can use the Fire Stick remote to navigate. The Roku TV itself is still running in the background, but you are now controlling the Fire Stick. When you want to go back to Roku apps or live TV, press the input button again and select the Roku input.

This setup works with any Roku TV model, including Roku-branded TVs and TVs made by other manufacturers (TCL, Hisense, Insignia) that have Roku built in. The Fire Stick does not interfere with the TV's normal operation.

When you might not need a Fire Stick on a Roku TV

Many Roku TVs already have the most popular streaming apps built in: Netflix, Prime Video, Disney+, Hulu, HBO Max, and others. If you primarily watch these services, your Roku TV may already do what you need. Check your TV's app store before buying a Fire Stick.

Roku also has its own free ad-supported channels (The Roku Channel, Pluto TV, Tubi) that compete with Fire Stick's free offerings. If you are interested in free streaming, Roku's selection is substantial and requires no additional hardware.

The main reasons to add a Fire Stick to a Roku TV are if you want access to exclusive Fire Stick features (like Alexa voice control through the remote), if you subscribe to services not available on Roku, or if you prefer Fire Stick's interface and app selection. Otherwise, your Roku TV alone may be sufficient.

Using a universal remote with Fire Stick and Roku TV

If managing two remotes feels cumbersome, you can buy a universal remote that works with both systems. Some universal remotes (like those from Logitech or GE) can be programmed to control both your Roku TV and Fire Stick. This reduces the number of remotes on your coffee table, though setup requires pairing each device separately.

Amazon also sells the Fire TV Cube, which includes an Alexa voice remote. The Cube can control some Roku TV functions through HDMI-CEC (a feature that lets devices communicate over HDMI), though not all Roku models support this fully. Check your TV's manual to see if it supports HDMI-CEC before relying on this.

A simpler option is to use your TV's native remote app. Many Roku TVs have smartphone apps that let you control the TV from your phone. You can use the phone app for Roku and the Fire Stick remote for Fire Stick content, eliminating the need for a universal remote.

Fire Stick alternatives if you want a single system

If you want to avoid managing two devices, consider whether your Roku TV already meets your needs. Roku's app store is large, and most major streaming services are available. Roku also supports AirPlay and Chromecast, so you can cast content from your phone or computer to the TV without additional hardware.

If your Roku TV is missing a specific app, check whether that app is available in Roku's app store before assuming you need a Fire Stick. Roku adds new apps regularly, and many services that were once exclusive to Fire Stick are now on Roku.

Another option is to replace your Roku TV with a Fire TV Edition TV, which runs Fire OS natively. These TVs are made by brands like Insignia and Toshiba and come with Fire TV built in. However, this is only practical if you are already planning to buy a new TV.

HDMI port and power considerations

Before connecting a Fire Stick to your Roku TV, check that you have an available HDMI port. Most TVs have three to four HDMI ports. If all ports are in use (by a cable box, gaming console, or soundbar), you will need to unplug something or buy an HDMI switch.

The Fire Stick also needs power. It comes with a power adapter and a short cable. Make sure you have an outlet near your TV, or use an extension cord. Some older Fire Stick models could draw power from the TV's USB port, but newer models require their own power adapter.

Check your TV's manual to confirm which HDMI ports support the features you want. Some TVs have HDMI ports with different capabilities (for example, one port might support ARC for soundbar connection). Use a standard HDMI port for the Fire Stick and reserve special ports for devices that need them.

Frequently Asked Questions

Can I control my Roku TV with the Fire Stick remote?

Not directly. The Fire Stick remote controls the Fire Stick and its apps. You need your Roku remote to control the TV itself, change inputs, or access Roku apps. Some Fire TV devices with Alexa can control limited Roku TV functions through HDMI-CEC, but this depends on your TV model and is not reliable across all Roku TVs.

Will a Fire Stick slow down my Roku TV?

No. The Fire Stick is a separate device that connects via HDMI. It does not affect your Roku TV's performance or processing speed. When you switch to the Fire Stick input, you are running the Fire Stick's processor, not your TV's. When you switch back to Roku, the TV runs normally.

Can I use Fire Stick's Alexa voice remote on a Roku TV?

The Fire Stick's Alexa remote can control Fire Stick apps and services through voice commands. It can also control some Roku TV functions if your TV supports HDMI-CEC, but this is limited and varies by model. For full Roku TV control, you still need the Roku remote.

What if my Roku TV does not have an available HDMI port?

You can buy an HDMI switch (a small device that lets multiple HDMI cables connect to one port). Plug the switch into your TV's HDMI port, then plug your Fire Stick and other devices into the switch. You can then select which device to use from the switch's controls.

Is it worth buying a Fire Stick if I already have a Roku TV?

Only if your Roku TV is missing apps or features you want. Check your TV's app store first. If the services you use are already available on Roku, a Fire Stick adds complexity without benefit. If you need specific apps only Fire Stick offers, or prefer Fire Stick's interface, then it may be worth the cost.
