The basic connection process

Connecting a device to your Roku TV depends on what you're trying to connect. If you want to stream from your phone, tablet, or computer, you use the built-in screen mirroring feature. If you want to connect a cable box, gaming console, or external device, you plug it into one of the HDMI ports on the back of the TV. The Roku TV itself connects to your home WiFi network during setup, which is what lets you stream apps like Netflix, Hulu, and others.

Most people connect their Roku TV to the internet first, then add other devices as needed. The TV's remote has a pairing button that syncs wirelessly, so you don't need to point it at the screen like older remotes. Once your Roku TV is on your WiFi network, you can control it from the mobile app on your phone instead of the physical remote if you prefer.

Key Takeaways

  • Your Roku TV connects to WiFi during the initial setup, which takes about five minutes and requires your network password.
  • The Roku remote pairs wirelessly and does not need line-of-sight to the TV, so you can control it from another room.
  • Screen mirroring from phones and tablets works through the Roku app or your device's built-in casting feature, depending on whether you have an iPhone or Android phone.
  • External devices like cable boxes and game consoles plug directly into the HDMI ports on the back of the TV and do not need WiFi.
  • If your Roku TV loses WiFi connection, restarting the TV or your router usually restores it within a few minutes.

Connecting your Roku TV to WiFi during setup

When you first turn on a new Roku TV, it walks you through a setup process that takes about five minutes. The TV will ask you to select your home WiFi network from a list, then enter your password. Use the remote to navigate the on-screen keyboard — the arrow buttons move between letters, and the OK button selects each one. If you have a Roku remote with a microphone button, you can speak your password instead of typing it, which is faster and less error-prone.

After you enter your WiFi password, the TV connects to the network and may download a software update. This can take a few minutes. Once it finishes, you'll see the Roku home screen with app tiles like Netflix, Prime Video, and others. At this point, your TV is ready to use. If you skip WiFi setup initially, you can add it later by going to Settings > Network on the TV remote.

Pairing your Roku remote

The Roku remote pairs to your TV automatically during setup, but if you buy a new remote or need to pair a replacement, the process is simple. Hold the pairing button on the back of the remote for about three seconds — you'll see a light flash on the remote. The TV will show a pairing screen, and within a few seconds the remote will connect. You don't need to point the remote at the TV; it uses a wireless connection that works through walls and furniture.

If the remote doesn't pair, make sure the TV is powered on and try again. If you have a voice remote with a microphone, the pairing process is the same. Once paired, the remote will work from anywhere in your home as long as the TV is on and connected to power.

Mirroring your phone or tablet to the TV

If you have an Android phone or tablet, you can mirror your screen to the Roku TV using the built-in casting feature. Open the notification panel on your Android device (swipe down from the top), look for "Cast" or "Screen Cast", and tap it. Your Roku TV should appear in the list. Tap the TV name, and your phone's screen will appear on the television within a few seconds. This works for apps, photos, videos, or anything else on your phone.

If you have an iPhone or iPad, the process is different because Apple uses AirPlay instead of standard casting. You can use the Roku app on your iPhone to control the TV, but direct screen mirroring from an iPhone to a Roku TV is not supported. However, you can use AirPlay to send audio and video from certain apps like Apple TV, Apple Music, or photos from the Photos app if your Roku TV has AirPlay built in — check your TV's specifications to confirm.

To stop mirroring, open the notification panel on your Android device again and tap the cast icon to disconnect. The TV will return to the Roku home screen.

Connecting external devices through HDMI

Cable boxes, gaming consoles, Blu-ray players, and other external devices connect to the HDMI ports on the back of your Roku TV. Look for the ports labeled HDMI 1, HDMI 2, HDMI 3, and HDMI 4 — most Roku TVs have four ports. Plug the HDMI cable from your external device into any available port. You don't need to use a specific port; they all work the same way.

Once you plug in the cable, turn on the external device. The TV should automatically detect it and switch to that input, or you may need to press the Input button on the Roku remote and select the HDMI port where you plugged it in. If the TV doesn't switch automatically, use the remote to navigate to the input list and select the correct HDMI port by name or number.

External devices do not need WiFi to work — they only need the HDMI cable connection. This means your cable box or gaming console will work even if your Roku TV loses internet connection.

Using the Roku mobile app to control your TV

The Roku app, available for both iPhone and Android, lets you control your Roku TV from your phone without using the physical remote. Download the app from the Apple App Store or Google Play Store, open it, and it will search for your Roku TV on the same WiFi network. Tap your TV name when it appears, and the app will connect. You'll see a virtual remote on your phone screen with all the same buttons as the physical remote.

The app also has a keyboard feature that makes typing passwords and search terms much faster than using the remote's arrow buttons. If you want to use voice commands, some Roku remotes and the app support voice search — just tap the microphone icon and speak what you're looking for. The app works from anywhere in your home as long as your phone and TV are on the same WiFi network.

Troubleshooting connection problems

If your Roku TV loses WiFi connection, the first step is to restart the TV. Unplug it from the power outlet, wait 30 seconds, and plug it back in. This fixes most connection issues. If the TV still can't find your WiFi network, restart your router the same way — unplug it, wait 30 seconds, and plug it back in. Give the router a few minutes to fully restart before trying to connect the TV again.

If your remote stops responding, the batteries may be low. Replace them with fresh AA batteries and try again. If the remote still doesn't work, try pairing it again by holding the pairing button on the back for three seconds. If screen mirroring from your phone isn't working, make sure both your phone and TV are on the same WiFi network, then try disconnecting and reconnecting from the cast menu.

If you're having trouble with an external device like a cable box, check that the HDMI cable is fully inserted into both the TV and the device. Try a different HDMI port on the TV to rule out a faulty port. If the device still doesn't appear, restart both the external device and the TV.

Frequently Asked Questions

Do I need to connect my Roku TV to WiFi to watch cable or use a gaming console?

No. External devices like cable boxes and gaming consoles connect through HDMI and work without any internet connection. You only need WiFi if you want to use streaming apps like Netflix or Hulu, or if you want to use the Roku app on your phone to control the TV.

Can I use my Roku TV without the physical remote?

Yes. The Roku mobile app works as a full remote replacement on both iPhone and Android. You can also use voice commands through the app if your TV supports it. However, you'll need the physical remote to pair the TV to WiFi during initial setup.

Why does my Roku TV keep disconnecting from WiFi?

This usually happens if your router is too far away or if there's interference from other devices. Try moving the router closer to the TV, or restart both the TV and router. If the problem continues, check that your router's WiFi password hasn't changed, and reconnect the TV to the network through Settings > Network.

Can I mirror my iPhone screen to a Roku TV?

Direct screen mirroring from iPhone to Roku TV is not supported. You can use the Roku app to control the TV from your iPhone, and you can use AirPlay to send video from certain Apple apps if your Roku TV has AirPlay built in, but full screen mirroring requires an Android phone or a different type of TV.

What should I do if a device won't show up on the HDMI input list?

First, make sure the HDMI cable is fully plugged into both the TV and the external device. Try unplugging the cable and plugging it into a different HDMI port on the TV. If the device still doesn't appear, restart both the TV and the external device, then try again.
