How to Connect Roku to TV with HDMI: A Simple Step-by-Step Guide

Roku makes it easy to stream your favorite content — but before you can start watching Netflix, Hulu, or YouTube, you need to properly connect your Roku device to your TV using an HDMI cable. Whether you're using a Roku Streaming Stick, Roku Express, or Roku Ultra, this guide walks you through each step.

How to Connect Roku to TV with HDMI

📦 What You’ll Need

• A Roku device (Streaming Stick, Express, Ultra, etc.)

• A TV with an HDMI input

• An HDMI cable (included with some Roku models)

• A power source (wall outlet or USB port)

🔌 Step-by-Step: How to Connect Roku to Your TV Using HDMI

Step 1: Identify Your Roku Device Type

There are several types of Roku devices:

• Roku Streaming Stick – plugs directly into the HDMI port

• Roku Express / Express 4K+ – uses HDMI cable to connect

• Roku Ultra – higher-end, comes with Ethernet port and USB options

The setup is very similar across devices — the main difference is whether the device connects directly or via an HDMI cable.

Step 2: Plug Roku into the HDMI Port

• For Roku Streaming Stick: plug it directly into an available HDMI port on the back or side of your TV.

• For Roku Express/Ultra: plug one end of the HDMI cable into the Roku device, and the other end into the TV's HDMI port.

💡 Most TVs have multiple HDMI ports. Note which one you use (e.g., HDMI 1, HDMI 2) — you’ll need to select it later on your TV.

Step 3: Connect the Power Supply

• Plug the USB power cable into the Roku device.

• Then plug the other end into a USB port on your TV or use the included wall adapter for a more reliable power source.

⚠️ If you're using the USB port on your TV and Roku restarts or lags, switch to the wall adapter instead — it provides more consistent power.

Step 4: Switch Your TV Input to the Correct HDMI Source

• Turn on your TV

• Use the remote to press the Input or Source button

• Select the HDMI input where your Roku is connected (e.g., HDMI 1)

Your TV should now display the Roku welcome screen.

Step 5: Set Up Your Roku

1. Pair the Roku remote if prompted

2. Choose your language and region

3. Connect to Wi-Fi

4. Sign in or create a Roku account

5. Let the device install any firmware updates

Follow the on-screen prompts to finish setup. Once complete, you can start adding and using your favorite streaming channels.
