What streaming from your PC means and how it works

Streaming from your PC means sending video, audio, or both from your computer to another device — a TV, phone, tablet, or another computer — over your home network or the internet. The PC acts as the source, and the receiving device displays or plays what your PC is sending. This is different from casting a single tab or mirroring your entire screen; streaming lets you send specific content while using your PC for other tasks.

The process works through software on your PC that encodes (compresses) the video or audio into a format the receiving device can understand, then transmits it over your network. The receiving device decodes it and plays it back. Most modern PCs have the hardware and software built in to do this — you just need to set it up.

Key Takeaways

  • Windows PCs can stream to TVs and other devices using built-in features like Miracast, or third-party apps like Plex, OBS, or Steam Link depending on what you want to stream.
  • Your PC and receiving device must be on the same network, or you must set up remote streaming through a service that supports it.
  • Streaming quality depends on your network speed — 5 Mbps is a minimum for 1080p video, and 25 Mbps or higher is better for smooth playback.
  • Some streaming methods require the receiving device to have a compatible app installed, while others work through a web browser.
  • If you want to stream games, Steam Link and NVIDIA GeForce Now are the most common options for Windows PCs.

Streaming to a TV using Miracast or HDMI alternatives

The simplest way to stream from a Windows PC to a TV is Miracast, a wireless standard built into Windows 10 and later. To use it, make sure your TV supports Miracast (most smart TVs made in the last five years do), then open the Windows Action Center by pressing Windows key + A. Select "Project" or "Connect," then choose your TV from the list. Your PC screen will appear on the TV within a few seconds.

If your TV does not support Miracast, you can use a Miracast adapter — a small device that plugs into your TV's HDMI port and receives the wireless signal from your PC. These cost between $20 and $60. Alternatively, if your TV has an HDMI port, the most reliable method is a physical HDMI cable from your PC to the TV, though this limits how far you can sit from the PC.

Miracast works best for presentations, photos, or casual video watching. It is not ideal for gaming or fast-action content because wireless transmission introduces a slight delay (called latency). For those uses, see the gaming section below.

Streaming video and music to phones and tablets

Plex is the most common choice for streaming your own video and music files from your PC to phones, tablets, or other devices. You install the Plex Media Server software on your PC, point it to the folders where your videos and music live, and then use the Plex app on your phone or tablet to watch or listen. Plex works both on your home network and remotely over the internet, so you can watch your content away from home.

Plex is free for basic use, though a paid Plex Pass ($5 per month or $120 per year) unlocks features like offline downloads and better remote streaming quality. You will need to create a free Plex account to use it.

If you want to stream only music, Subsonic and Jellyfin are open-source alternatives that work similarly — they run on your PC and let you stream to other devices. Both are free, though Subsonic asks for a donation after a trial period.

Streaming games from your PC

Steam Link is the standard way to stream games from a Windows PC to another device in your home. You install Steam Link on your TV (if it has an app), on a Fire TV device, on a Raspberry Pi, or on another PC or Mac, then connect it to the same network as your gaming PC. Steam Link streams the game at up to 4K resolution and 120 frames per second if your network is fast enough. It is free.

NVIDIA GeForce Now works differently — instead of streaming from your PC, it streams games from NVIDIA's servers to your PC or other device. You need a GeForce Now subscription (free tier with limitations, or $9.99 per month for the premium tier), and you must own the games on Steam, Epic Games, or another supported platform. This is useful if you want to play demanding games on a weaker PC or device.

For streaming to a phone or tablet, Xbox Game Pass for PC includes cloud gaming, which lets you play games on your phone through the Xbox app. You need a Game Pass subscription ($11.99 per month).

Setting up your network for streaming

Streaming quality depends heavily on your network. For smooth video streaming, your PC and receiving device should be on the same Wi-Fi network, ideally a 5 GHz band if your router supports it (5 GHz is faster than 2.4 GHz, though it has shorter range). If you are streaming over the internet to a device outside your home, your upload speed matters — most services recommend at least 5 Mbps upload for 1080p streaming.

If streaming is choppy or keeps stopping, move your PC or receiving device closer to the router, or switch to a wired Ethernet connection on your PC if possible. A wired connection is always more stable than Wi-Fi. You can also reduce the streaming quality in your app's settings to use less bandwidth.

If you are streaming over the internet (not just your home network), check whether your internet service provider has a data cap. Streaming video uses significant data — roughly 3 GB per hour for 1080p video.

Streaming your PC screen to another computer

If you want to share your entire PC screen with another computer, Windows Quick information is built into Windows 10 and later. Open Quick information, select "Give information," and share the code with the person you want to help. They enter the code, and you can see their screen and control it if they allow. This is meant for tech support, not entertainment streaming.

For remote access to your own PC from another computer, Chrome Remote Desktop (free) or TeamViewer (free for personal use) let you see and control your PC from anywhere. These are useful if you want to access files or run programs on your PC while away from home, but they are not designed for streaming video or games.

Streaming to smart home devices and speakers

If you want to stream audio to smart speakers like Amazon Echo or Google Home, most of these devices support Bluetooth — you can pair your PC with the speaker and play music through it. Open your PC's Bluetooth settings, put the speaker in pairing mode, and select it from the list.

For more control, some speakers support AirPlay (Apple devices and some third-party speakers) or Chromecast (Google devices). If your PC does not have built-in support, you can use third-party software like AirServer or Pulsar to add these features, though these cost money.

Frequently Asked Questions

Do I need a special PC to stream, or will any Windows computer work?

Any Windows 10 or later PC can stream. Older hardware will work, but streaming quality depends on your PC's processor and network card. If your PC is very old, it may struggle to encode video smoothly, which will cause stuttering on the receiving device.

Can I stream from my PC to a TV without Wi-Fi?

Yes. A physical HDMI cable is the most reliable method and does not require Wi-Fi. Miracast adapters also work without Wi-Fi if both devices support the standard. For other methods like Plex, you need a network connection (Wi-Fi or wired Ethernet).

What if the receiving device does not have an app for the streaming service I want to use?

Many streaming services work through a web browser — you can open a browser on the receiving device and visit the service's website. Plex, Jellyfin, and others support this. If the device has no browser, you are limited to services that have made an app for that device.

Will streaming from my PC slow down my internet for other devices?

Only if you are streaming over the internet to a device outside your home. Streaming within your home network uses your local Wi-Fi or Ethernet and does not affect your internet speed. Remote streaming uses your upload speed, which can slow down other internet activity if your upload is slow.

Can I stream from my PC while it is in sleep mode?

No. Your PC must be awake and running for streaming to work. You can set your PC to stay on longer before sleeping, or disable sleep mode entirely if you stream regularly. Check your power settings in Windows to adjust this.
