How to Stream From Your Computer to Roku: Untether Your Content!

So, you’ve got a treasure trove of movies, home videos, or perhaps a niche collection of independent films residing on your computer. You crave the big-screen experience, the comfort of your couch, and the simplicity of your Roku remote. The good news? Streaming from your computer to your Roku is eminently achievable, unlocking a world of viewing possibilities.

The most common and reliable methods involve leveraging Roku’s built-in screen mirroring functionality (Miracast) or utilizing a DLNA-compatible media server on your computer. Let’s break down both approaches in detail.

Method 1: Screen Mirroring (Miracast) – The Wireless Wonder

Screen mirroring, often relying on the Miracast protocol, is a straightforward method that projects your computer’s display directly onto your Roku-connected TV. Think of it as a wireless HDMI cable.

Setting Up Screen Mirroring: A Step-by-Step Guide

Ensure Compatibility: First and foremost, confirm that both your computer and your Roku support screen mirroring. Most modern Windows computers (Windows 8.1 and later) and Roku devices (check your Roku model’s specifications) offer Miracast support.
Enable Screen Mirroring on Your Roku: Navigate to your Roku’s settings. Typically, you’ll find the screen mirroring option under “Settings” > “System” > “Screen mirroring.” Choose a mode: “Prompt” (requires permission each time), “Always Allow” (connects automatically), or “Never Allow” (disables mirroring). “Prompt” is generally recommended for security.
Connect from Your Windows Computer:
- Press the Windows key + K simultaneously. This opens the “Connect” pane, which searches for available wireless displays.
- Select your Roku device from the list.
- Your computer’s screen should now appear on your TV via your Roku.
Adjust Display Settings (Optional): You can configure how your screen is mirrored. Right-click on your desktop, select “Display Settings,” and choose “Duplicate” (shows the same image on both screens) or “Extend” (treats your TV as a second monitor). The “Duplicate” option is generally best for simply watching content.

Troubleshooting Screen Mirroring

Connection Issues: If your Roku isn’t appearing in the “Connect” pane, ensure both devices are on the same Wi-Fi network and that screen mirroring is enabled on your Roku. Restarting both devices can also help. Check your firewall settings to ensure Miracast is not being blocked.
Performance Problems: Screen mirroring relies heavily on Wi-Fi. A weak or congested Wi-Fi network can lead to lag, stuttering, or poor image quality. Consider moving your Roku and computer closer to your router or using a 5 GHz Wi-Fi network if available.
Driver Issues: Outdated or incompatible graphics drivers on your computer can also cause problems. Update your drivers from your computer manufacturer’s website.

Method 2: DLNA Media Server – The Organized Oasis

A DLNA (Digital Living Network Alliance) media server allows you to stream content stored on your computer to your Roku in a more structured and organized way. It acts as a central hub for your media library.

Setting Up a DLNA Server:

Choose a DLNA Server Software: Several excellent (and often free) DLNA server options exist:
- Plex: A powerful and feature-rich media server that organizes your library with metadata, posters, and descriptions. It requires creating a free Plex account.
- Kodi: Another open-source option offering extensive customization and support for various add-ons.
- Windows Media Player: A built-in option on Windows computers, though less feature-rich than Plex or Kodi.
- Universal Media Server: A straightforward and versatile DLNA server.
Install and Configure the Software: Download and install your chosen DLNA server software. Follow the software’s instructions to configure it. This typically involves:
- Specifying the folders on your computer that contain your media files (movies, TV shows, music, photos).
- Naming your DLNA server (this will be the name that appears on your Roku).
- Configuring network settings (usually, the default settings are sufficient).
Access the DLNA Server on Your Roku:
- Download and install the corresponding Roku channel for your DLNA server. For Plex, install the “Plex” channel. For Windows Media Player, install the “Roku Media Player” channel.
- Open the channel on your Roku.
- The channel should automatically detect your DLNA server. Select it.
- Browse your media library and enjoy!

Troubleshooting DLNA Server Issues:

Server Not Found: Ensure your computer and Roku are on the same network. Verify that the DLNA server software is running on your computer and that it’s configured to share media. Firewalls can sometimes block DLNA connections; check your firewall settings.
Playback Problems: Video format compatibility can be an issue. Some video formats (like .avi or .mkv with certain codecs) may not be directly supported by your Roku. Plex can often transcode videos on the fly to a compatible format. If using other DLNA servers, consider converting unsupported videos to a Roku-friendly format like MP4 using a video converter.
Metadata Issues: If Plex isn’t correctly identifying your media files, double-check your file naming conventions. Plex relies on specific naming schemes to match your files with metadata from online databases.

Choosing the Right Method

Screen Mirroring: Best for quickly displaying anything on your computer screen, including applications, websites, or content that isn’t easily accessible through a DLNA server. It’s less organized but more flexible.
DLNA Media Server: Ideal for managing and streaming a large library of movies, TV shows, and music. Offers a more organized and user-friendly experience, especially with Plex.

Bonus Tip: Utilizing USB Drives

While this article focuses on streaming from your computer, don’t forget the humble USB drive. You can directly play media files from a USB drive plugged into your Roku using the Roku Media Player. This is a great option for occasional viewing or when Wi-Fi isn’t available.

Frequently Asked Questions (FAQs)

Here are some frequently asked questions to help you navigate the world of streaming from your computer to your Roku.
