To connect your laptop to a Roku TV with HDMI, you only need a laptop with an HDMI port and a Roku TV with a free HDMI port. Plug one end of an HDMI cable into your laptop and the other into the TV, then select the correct input on the Roku remote.
Step 1: Connect the HDMI cable
Physically connect the HDMI cable by inserting one end into your laptop's HDMI output port and the other end into an available HDMI port on your Roku TV. Note the port label beside the physical port (e.g., HDMI 1, HDMI 2) so you can match it later.
Step 2: Select the correct input on your Roku TV
Turn on both your laptop and your Roku TV. Use your Roku remote and press the button labeled "Input" or "Source" to bring up the input menu. Select the correct HDMI input corresponding to the port where your laptop is connected (e.g., HDMI 1, HDMI 2). Wait approximately 10 seconds for the TV to detect the signal.
Troubleshooting common connection problems
If your laptop screen doesn't appear after following the steps above, the most frequent issues are a blank screen, a missing input, or a dull picture. The fixes below address each problem in order.
Fix a 'No signal' or blank screen
- Ensure the connected device (your laptop) is turned on.
- Disconnect and firmly reconnect both ends of the HDMI cable.
- Try another HDMI cable if available.
- Connect the laptop directly to the TV instead of through a soundbar, receiver, or adapter.
- Try the laptop on another HDMI port on the TV.
Find a missing or hidden HDMI input
If the HDMI input appears to be missing, it may have moved, been hidden, or not yet been set up. On newer Roku Home Screen layouts, HDMI inputs may appear in the "Apps" section. To find a missing input, press the "Home" button and scroll down to "Apps" to look for HDMI 1, HDMI 2, or HDMI 3. If found, highlight the input and press the "Star" button to "Move app" or "Move to top" for easier access. To add a hidden HDMI input to the Home screen, press "Home" on the Roku remote, go to "Settings" > "TV inputs" or "Inputs", select the missing HDMI port, and then select "Set up input" or "Show input". Confirm you have selected the correct HDMI port on the TV that matches the label beside the physical port where the laptop is connected.
Adjust the HDMI mode for better picture quality
If the picture looks dull or if you are connecting a 4K, 8K, or HDR device, you may need to change the HDMI mode for the port. To change the HDMI mode, press "Home" on your Roku remote. Go to "Settings" > "Inputs". Select the HDMI input your device is connected to. Choose "HDMI mode", then select one of the following options: "Auto" (best for most devices), "Compatibility" (for older devices, may lower picture quality), or "Standard" (best for newer devices supporting 4K HDR and gaming features). If the picture is blank or not displayed correctly after changing the HDMI mode, press "Home" to return to the main screen, go back to "Settings" > "Inputs", and select a different HDMI mode. For 4K or HDR content, ensure your Roku TV supports 4K or 8K resolution and HDR (HDR10, Dolby Vision, etc.), your connected device supports 4K, 8K, or HDR, you are using a high-speed HDMI cable made for 4K or 8K, and the HDMI port settings on your Roku TV are correct. Some gaming consoles support HDR but not HDCP 2.2, which can cause problems with 4K or HDR content. HDCP is a copy protection feature required by the TV to play certain content. If you still have trouble, you can contact Roku (How Do I Contact Roku) for further assistance. Menu names and locations may vary slightly depending on the TV model and Roku software version.
