Yes, you can stream from one Windows computer to multiple computers at once

Windows has built-in tools and third-party software that let you send your screen, audio, or specific applications to other computers on your network or over the internet. The method you choose depends on whether you want to share your entire desktop, stream just one window, or let others control your computer remotely. Some approaches work only on your home network, while others work anywhere.

The most straightforward option for local networks is Miracast, which is built into Windows 10 and Windows 11. For more control and the ability to stream to many devices at once, third-party software like OBS Studio (free) or commercial tools give you more flexibility. If you need remote access from outside your home, Windows Remote Desktop or Chrome Remote Desktop work well but typically connect one person at a time.

Key Takeaways

  • Miracast is the simplest built-in option for Windows 10 and 11, but it streams to one device at a time and only works on your local network.
  • OBS Studio is free software that can broadcast your screen to multiple computers simultaneously using streaming protocols like RTMP.
  • Windows Remote Desktop and Chrome Remote Desktop allow remote control but are designed for one-to-one connections, not one-to-many streaming.
  • Streaming to multiple devices at once requires either third-party software or a streaming service that acts as a middleman between your computer and viewers.
  • Network bandwidth matters: streaming to many devices at once uses significant upload speed, so a wired connection is better than Wi-Fi when possible.

Using Miracast for wireless screen sharing on your local network

Miracast is the easiest method if you only need to stream to one device at a time and everyone is on the same Wi-Fi network. It is built into Windows 10 and Windows 11, so you do not need to install anything. Open the Action Center (press Windows key + A), click "Connect," and select the device you want to stream to. Your screen will appear on that device after a few seconds.

The limitation is that Miracast only connects to one receiving device at a time. If you disconnect and reconnect to a different device, the first one stops receiving your stream. Miracast also only works on your local network—you cannot use it to stream to a computer across the internet. The receiving device must support Miracast, which most modern laptops, tablets, and smart TVs do, but you should check the specifications of older devices.

Miracast works best when both computers are plugged into power and close to your router. Wi-Fi interference or distance from the router can cause lag or disconnections. If you experience problems, try moving closer to the router or switching to the 5 GHz Wi-Fi band if your router supports it.

Streaming to multiple computers at once with OBS Studio

OBS Studio is free software that lets you broadcast your screen to many computers simultaneously. Unlike Miracast, OBS gives you control over what part of your screen to show, lets you add text or images, and can stream to multiple viewers at the same time. read OBS Studio from obsproject.com and install it on the computer you want to stream from.

After opening OBS, click the plus sign under "Sources" and select "Display Capture" to add your entire screen, or "Window Capture" to show only one process. Then go to "Settings" and choose "Stream" to pick a streaming service. OBS can stream to Twitch, YouTube, or a local network address. For streaming within your home network without using the internet, you can set up a local RTMP server, though this requires more technical setup.

The receiving computers do not need OBS installed. They straightforward open a web browser and go to the streaming address you provide, or they watch on Twitch or YouTube if you stream there. OBS uses more of your computer's processing power than Miracast, so close other heavy applications before streaming. The quality and smoothness depend on your internet upload speed—faster upload means better quality to multiple viewers.

Remote access versus streaming: which one you actually need

Remote access tools like Windows Remote Desktop and Chrome Remote Desktop are often confused with streaming, but they work differently. These tools let someone else take control of your computer from another device, as if they were sitting at your keyboard. They are one-to-one connections: one person controls, one person watches. They are not designed to broadcast to many viewers at once.

Windows Remote Desktop is built into Windows Pro, Enterprise, and Education editions (not Home). To use it, go to Settings, search for "Remote Desktop," and turn it on. The other person needs to know your computer's name and password. Chrome Remote Desktop works on any Windows version and is easier to set up—both computers just need the Chrome browser and the Remote Desktop extension installed.

Use remote access when you want someone to help you troubleshoot a problem or when you need to work on your computer from somewhere else. Use streaming when you want to show your screen to multiple people without giving them control, or when you want to record what you are doing.

Setting up streaming over the internet instead of just your local network

Miracast and local OBS setups only work on your home Wi-Fi network. To stream to computers outside your home, you need either a public streaming service or software that creates a find tunnel over the internet.

The simplest approach is to use OBS with a public streaming platform like Twitch or YouTube. You create a free account, get a stream key from the platform, paste it into OBS, and anyone with the stream link can watch from anywhere. The downside is that your stream is public (or limited to people you share the link with), and there is a slight delay between what you do and what viewers see.

For private streaming without a public platform, you can use software like Parsec or Sunshine, which create encrypted connections over the internet. These are more complex to set up but give you more privacy and lower latency. Both require port forwarding on your router, which involves logging into your router's settings—contact your internet provider if you are unsure how to do this.

Bandwidth and network requirements for streaming to multiple devices

Streaming to multiple computers at once uses a lot of upload bandwidth. If your internet upload speed is slow, the stream will be choppy or low quality for viewers. Check your upload speed at speedtest.net—most home internet plans have upload speeds between 5 and 25 Mbps. Streaming to three or four devices at once typically needs at least 10 Mbps upload.

On your local network, use a wired Ethernet connection on the computer you are streaming from if possible. Wi-Fi is convenient but slower and more prone to interference. If the receiving computers are also wired, they will get a smoother, more reliable stream. If you must use Wi-Fi, position your router centrally and away from walls and metal objects.

If you are streaming over the internet using a service like Twitch or YouTube, the platform handles sending your stream to multiple viewers, so your upload speed only needs to support one stream to the platform. However, the quality you can send depends on your upload speed—faster upload means higher resolution and smoother video.

Common problems and how to fix them

Miracast says "can't connect": Make sure both devices are on the same Wi-Fi network and that the receiving device supports Miracast. Restart both devices and try again. If the problem continues, update your graphics drivers on the computer you are streaming from.

OBS stream is choppy or freezes: Lower the resolution or frame rate in OBS settings. Close other applications that use the internet or CPU. If you are streaming over Wi-Fi, move closer to your router or switch to a wired connection. Check your upload speed—if it is below 5 Mbps, reduce the bitrate in OBS.

Remote Desktop says "connection refused": Make sure Remote Desktop is turned on in Settings on the computer you are trying to connect to. Check that you are using the correct computer name. If you are connecting over the internet, you may need to set up port forwarding on your router.

Receiving computers cannot find the stream: Make sure all devices are on the same network. If using OBS with a local stream, check that the streaming address is correct. If using a public platform like Twitch, verify that the stream key is correct and that the stream is actually running.

Frequently Asked Questions

Can I stream to more than 10 computers at once?

Yes, but it depends on the method. Miracast only works with one device at a time. OBS streaming to a public platform like Twitch or YouTube can reach thousands of viewers simultaneously. For local network streaming with OBS, the limit depends on your router and network bandwidth—most home routers can handle 10 to 20 simultaneous viewers before performance drops.

Do the receiving computers need Windows, or can they be Mac or Linux?

Miracast works best with Windows and some Android devices, though some Macs support it. OBS streams to a web browser, so any device with a browser (Windows, Mac, Linux, phone, tablet) can watch. Remote Desktop works on Windows, Mac, and Linux with the right software installed.

Will streaming slow down my computer or internet for other people using it?

Yes. Streaming uses CPU power on your computer and upload bandwidth on your internet connection. Other people on your network may notice slower speeds. Wired connections are less affected than Wi-Fi. If streaming is important, consider upgrading your internet plan or using a computer dedicated to streaming.

Is it safe to stream my screen to other computers?

Miracast and Remote Desktop use encryption, so they are reasonably find on your home network. Public streaming platforms like Twitch are find but your stream is visible to anyone with the link. If you are streaming sensitive information, use a private streaming service or keep the stream link to yourself.

What if my Windows computer does not support Miracast?

Older Windows 7 computers and some Windows 10 machines with older graphics cards do not support Miracast. Use OBS Studio instead, which works on any Windows version. You can also use third-party software like AnyDesk or TeamViewer, though these are primarily designed for remote control rather than broadcasting to many viewers.
