The basic connection: what you need and where to plug things in
Connecting a Roku to your TV takes about five minutes and requires only the device itself, an HDMI cable, and power. Roku makes several models — the Roku Streaming Stick, Roku Box, Roku Ultra, and others — but they all connect the same way.
Plug the HDMI cable into the HDMI port on the back or side of your Roku device. Then plug the other end into any available HDMI port on your TV. Most TVs have two to four HDMI ports, usually labeled HDMI 1, HDMI 2, and so on. It does not matter which one you use. Next, plug the Roku's power cable into a wall outlet or USB port. The device will power on automatically within a few seconds.
Turn on your TV and use the remote to switch to the HDMI input where you plugged in the Roku. On most remotes, this is a button labeled "Input," "HDMI," or "Source." Press it and select the matching HDMI port number from the menu that appears. Your Roku home screen should now be visible.
Key Takeaways
- Connect the Roku to your TV using an HDMI cable, then plug the Roku's power adapter into a wall outlet.
- Switch your TV's input to the HDMI port where you plugged in the Roku using the Input or Source button on your remote.
- When the Roku home screen appears, connect to your Wi-Fi network using the on-screen menu and your TV remote.
- Sign in with a Roku account or create one free to access streaming apps and services.
- If your TV has only one HDMI port, you may need an HDMI splitter or to unplug another device to make room for the Roku.
Connecting to Wi-Fi so your Roku can reach the internet
Once the Roku home screen is visible, you need to connect it to your Wi-Fi network. The Roku will prompt you to do this automatically the first time it starts. Use your TV remote to navigate the on-screen menu and select your Wi-Fi network from the list.
Type in your Wi-Fi password using the on-screen keyboard. The Roku remote has a microphone button (usually marked with a microphone icon) that lets you speak the password instead of typing it character by character, which is faster and less error-prone. Once you enter the password correctly, the Roku will connect to the internet.
If your Wi-Fi network does not appear in the list, make sure your router is turned on and within range. Roku devices work best when they are within 30 feet of your router. If you are too far away, move the Roku closer or consider using a Wi-Fi extender.
Setting up your Roku account and finding apps
After connecting to Wi-Fi, the Roku will ask you to sign in with a Roku account. You can create one free using an email address and password. This account lets you download apps, save preferences, and access your streaming services across any Roku device you own.
Once you are signed in, you will see the Roku home screen with a menu of available apps and channels. Popular services like Netflix, YouTube, Hulu, and Disney+ are usually pre-installed or available to download for free. Search for the apps you want using the search function, then select "Add Channel" to install them.
Some apps require a subscription or login with your account for that service. For example, if you have a Netflix subscription, you will need to sign in with your Netflix email and password the first time you open the Netflix app on your Roku.
Troubleshooting when your Roku will not connect to the TV
If the Roku powers on but nothing appears on your TV screen, the most common cause is that your TV is set to the wrong input. Check that you selected the correct HDMI port number on your TV remote. Try pressing the Input or Source button again and cycling through each HDMI option until you see the Roku home screen.
If the HDMI cable is loose or damaged, the picture may not appear. Unplug the HDMI cable from both the Roku and the TV, wait a few seconds, and plug it back in firmly. Make sure both ends are fully inserted. If you have a spare HDMI cable, try that instead to rule out a faulty cable.
If your TV is very old, it may not have an HDMI port at all. Older TVs use composite cables (red, white, and yellow connectors) or component cables (red, green, and blue connectors). In this case, you will need an HDMI-to-composite or HDMI-to-component converter, available at most electronics retailers for $15 to $30.
What to do if your TV has only one HDMI port
Many older TVs and some smaller models have only one HDMI port. If you already have another device plugged into it — such as a cable box, gaming console, or soundbar — you have two options.
The first option is to unplug the other device and plug in the Roku instead. You can switch between devices by unplugging one and plugging in the other, though this is inconvenient if you use both regularly.
The second option is to buy an HDMI splitter or HDMI switch. A splitter lets you plug multiple HDMI cables into one port and switch between them using a button on the device. A basic HDMI switch costs $15 to $40 and does not require power. Some newer switches are powered and offer additional features like automatic switching based on which device is active.
Using your Roku remote and adjusting picture settings
The Roku remote controls everything on your device. The directional pad navigates menus, the OK button selects items, and the back button returns to the previous screen. Most Roku remotes also have dedicated buttons for popular apps like Netflix and Disney+, which take you directly to those services.
If your picture looks stretched, squashed, or has black bars on the sides, you may need to adjust your TV's picture settings rather than the Roku's. On your TV remote, look for a button labeled "Picture," "Display," or "Aspect Ratio." This controls how the image fills your screen. The Roku itself has minimal picture settings — most adjustments happen on your TV.
If the picture is too dark or too bright, check your TV's brightness and contrast settings first. If you need to adjust the Roku's output, go to Settings on the Roku home screen, select Display Type, and make sure it matches your TV's resolution. Most modern TVs support 1080p or 4K, and the Roku will automatically detect this.
Connecting a soundbar or external speakers to your Roku
If you want better audio than your TV's built-in speakers provide, you can connect a soundbar or external speakers. The method depends on what audio equipment you have.
If your soundbar or receiver has an HDMI port labeled ARC (Audio Return Channel), plug an HDMI cable from your TV's ARC port to the soundbar. This sends audio from the Roku through your TV to the soundbar. Not all TVs have ARC, so check your TV's manual or the ports on the back.
If your soundbar does not have HDMI ARC, connect it directly to your TV using an optical cable (a thin cable with a square connector) or a 3.5mm audio cable. Then go to Settings on the Roku home screen, select Audio, and choose the audio output that matches your setup. The Roku will send sound to both your TV and the external speaker.
Frequently Asked Questions
Do I need a Roku remote to use my Roku, or can I use my TV remote?
You need the Roku remote to navigate the Roku menus and select apps. Some newer TVs have universal remotes that can control Roku devices, but this is not standard. If you lose your Roku remote, you can buy a replacement for $20 to $50, or download the free Roku mobile app on your phone to use as a remote.
Can I connect my Roku to my TV wirelessly without an HDMI cable?
No. Roku devices require a physical HDMI connection to your TV. They cannot connect wirelessly. However, once connected, the Roku connects to the internet wirelessly through Wi-Fi, which is how it streams content.
What if my Roku keeps disconnecting from Wi-Fi?
Move your Roku closer to your Wi-Fi router or remove obstacles between them. If the problem continues, restart your router by unplugging it for 30 seconds, then plug it back in. You can also restart the Roku by going to Settings, selecting System, and choosing Restart. If you still have trouble, try "forgetting" the Wi-Fi network on the Roku and reconnecting with your password.
Can I use an extension cord to plug in my Roku if the outlet is far away?
Yes, a standard extension cord works fine for the Roku's power cable. Make sure the extension cord is rated for the power draw of your device — most Roku devices use less than 10 watts, so any household extension cord will work. Avoid daisy-chaining multiple extension cords together.
Why is my Roku picture blurry or pixelated?
This usually means your Wi-Fi signal is weak. Move the Roku closer to your router or reduce interference from other devices. You can also check your internet speed by going to Settings on the Roku home screen, selecting System, and choosing About. Roku recommends at least 3 Mbps for standard streaming and 15 Mbps for 4K. If your speed is lower, contact your internet provider or restart your router.
