How to Connect Your TV to a Roku Device

The basic connection: what you need and where to start

Connecting a TV to a Roku device means plugging the Roku into your television's HDMI port and then turning both on. The Roku is a small box or stick that streams video from the internet to your TV — it sits between your TV and your internet connection. Once plugged in, your TV will display the Roku's menu, and you can start watching streaming services like Netflix, YouTube, or Hulu.

You will need three things: a Roku device (either a Roku Streaming Stick or a Roku box), an HDMI cable (usually included with the Roku), and a TV with an available HDMI port. Most TVs made in the last ten years have at least two HDMI ports on the back or side. If your TV is older and has no HDMI ports, you will need a different type of device — ask at an electronics store about composite or component options.

The physical connection takes about two minutes. The setup that follows — connecting to your home WiFi and signing into streaming services — takes longer but walks you through each step on your TV screen.

Key Takeaways

A Roku plugs into your TV's HDMI port with a cable and connects to your home WiFi to stream video.
The HDMI cable usually comes with the Roku, but you need to know which HDMI port on your TV is available before you plug it in.
After plugging in the Roku and turning on your TV, the on-screen menu will guide you through connecting to WiFi and signing into your streaming accounts.
If your TV has no HDMI ports, you cannot use a standard Roku — you will need to explore other device types with your TV manufacturer or a retailer.

Finding the right HDMI port on your TV

Look at the back or side of your TV for ports labeled HDMI. They are small rectangular openings, usually grouped together. Most TVs have between two and four HDMI ports. Write down which port number you plan to use — this matters because you will need to switch your TV to that input after you plug the Roku in.

If your TV is wall-mounted, the ports are usually on the back, which can be hard to reach. If your TV sits on a stand, check both the back and the sides — some newer TVs have a port on the side for easier access. Before you buy a Roku, make sure you can actually reach an available HDMI port. If all your ports are already in use (by a cable box, gaming console, or soundbar), you may need to unplug something or buy an HDMI switch that lets multiple devices share one port.

Plugging in the Roku and powering it on

Take the HDMI cable that came with your Roku and plug one end into the HDMI port you identified. Plug the other end into the Roku device itself — there is only one HDMI port on the Roku, so it is impossible to plug it in wrong. The cable should fit snugly but not require force.

Next, plug the Roku's power cable into the device and then into a wall outlet or power strip. The Roku will light up, usually with a small LED indicator. Now turn on your TV using its remote. Your TV screen will either show the Roku menu right away, or it will show your regular TV input. If you see your normal TV input (cable channels or a blank screen), press the Input or Source button on your TV remote and select the HDMI port number where you plugged in the Roku.

Once you are on the correct HDMI input, you should see the Roku startup screen. This is the moment you know the physical connection worked.

Connecting to WiFi during setup

The Roku will ask you to connect to your home WiFi network. You will see a list of available networks on your TV screen — find your WiFi network name (also called the SSID) and select it. The Roku will then ask for your WiFi password. Use your TV remote to type in the password. The remote has a keyboard on it, or you can use the arrow buttons to select letters one at a time.

If you do not know your WiFi password, check the back or bottom of your router — it is usually printed there. If you have changed the password since you set up your router, you will need to remember that new password. Once you enter it correctly, the Roku will connect to your WiFi and move to the next step.

If the Roku cannot find your WiFi network, make sure your router is turned on and that you are within range. If your router is in another room and the signal is weak, the Roku may struggle to connect. Moving the Roku closer to the router temporarily can help during setup.

Signing into your streaming accounts

After WiFi is connected, the Roku will ask you to sign into your streaming services. You do not have to do this right now — you can skip this step and add services later. However, if you want to watch Netflix, Hulu, Disney+, or other services, you will need to sign in with the account you use on your phone or computer.

The Roku will guide you through signing into each service one at a time. For most services, the Roku will show you a code on your TV screen and ask you to go to a website on your phone or computer, enter that code, and sign in there. This is safer than typing your password on the TV remote. Once you sign in on your phone, the Roku automatically connects to that account.

You can add or remove streaming services anytime after setup is complete. The Roku home screen shows all your installed services as tiles you can click on to start watching.

Troubleshooting a connection that is not working

If you plugged everything in but your TV still shows a blank screen or your regular cable input, the most common problem is that you are not on the correct HDMI input. Press the Input or Source button on your TV remote and cycle through each HDMI port until you see the Roku startup screen. Write down which port number works so you remember it.

If the Roku powers on (you see a light on the device) but your TV shows nothing, try a different HDMI cable. The cable that came with the Roku is usually reliable, but it can be damaged. If you have another HDMI cable from a different device, test it to rule out a cable problem.

If the Roku connects to WiFi but then loses connection, move it closer to your router or check whether other devices in your home are having WiFi problems. If only the Roku is dropping connection, restart it by unplugging the power cable for 30 seconds and plugging it back in. If the problem continues, you may need to restart your router the same way.

Connecting a Roku to a TV without HDMI

Older TVs without HDMI ports cannot use a standard Roku Streaming Stick or box. However, Roku makes devices for older TVs — some models use composite cables (the red, white, and yellow cables) or component cables instead. Check your TV's ports to see what options you have, then visit Roku's website or ask a retailer which Roku model works with your TV type.

Another option is to replace your TV's connection method using an adapter, but this is usually more expensive and complicated than buying a compatible Roku model. If your TV is very old and has no HDMI, composite, or component ports, streaming devices may not be a practical option — you would need to upgrade your TV or use a different method to watch streaming content.

Frequently Asked Questions

Do I need a Roku remote to use the device?

Yes, the Roku remote comes with the device and controls everything on your TV screen. You cannot set up or use a Roku without it. Some newer Roku remotes have a microphone for voice search, but a basic remote works fine for all functions. If you lose your remote, you can buy a replacement or use the Roku mobile app on your phone as a remote.

Can I use any HDMI cable, or does it have to be the one that came with the Roku?

Any HDMI cable works, but the one included with your Roku is tested and reliable. If you need a longer cable to reach your TV, buy a standard HDMI cable from an electronics store — length does not matter as long as it is HDMI. Avoid very cheap cables from unknown sellers, as they may not work reliably.

What if my TV only has one HDMI port and it is already in use?

You can buy an HDMI switch or splitter that lets multiple devices share one port. Plug the switch into your TV's HDMI port, then plug both your Roku and your other device into the switch. You will need to manually switch between them using a button on the switch. This adds a step but solves the problem without unplugging devices.

Does the Roku need to be plugged in all the time?

Yes, the Roku needs constant power to work. It cannot run on batteries. Make sure the power outlet you use is reliable and not controlled by a light switch that might turn it off accidentally. If you want to turn off the Roku without unplugging it, you can put it in sleep mode using the remote.

Can I move the Roku to a different TV?

Yes, you can unplug the Roku from one TV and plug it into another. Your streaming accounts and settings will stay on the device. However, if the new TV is far from your WiFi router, the Roku may have trouble connecting — you may need to move your router or buy a WiFi extender to reach the new location.
