The fastest way to screen share from PC to TV
The simplest method depends on what's already plugged into your TV. If your TV has a HDMI port and you have an HDMI cable, plug one end into your PC and the other into your TV, then select that input on your remote — this takes 30 seconds and works when ready. If you want to share wirelessly without cables, use Miracast (built into Windows 10 and 11), Chromecast (if you own a Google Chromecast device), or AirPlay (if you have an Apple TV). Each method works differently and has different speed and reliability trade-offs.
The wired HDMI route is the most reliable because there's nothing to configure — your PC and TV talk directly. Wireless methods are more convenient if your PC is far from the TV, but they can lag slightly and occasionally drop connection. Your choice depends on whether you value simplicity (HDMI) or freedom of movement (wireless).
Key Takeaways
- HDMI cable is the fastest and most reliable method — plug in and switch your TV input, no setup required.
- Miracast is built into Windows 10 and 11 and works wirelessly with most modern TVs that support it, though you may need to enable it in your TV settings first.
- Chromecast and Apple TV require you to own those specific devices, but they work reliably once set up and let you share from anywhere in your home.
- Wireless methods can have 1 to 3 second delays and occasional disconnects, so they work better for watching video than for gaming or precise mouse control.
Using an HDMI cable (wired connection)
Plug an HDMI cable into the HDMI port on the back or side of your PC. Plug the other end into any available HDMI port on your TV. Turn on your TV and use the remote to select the correct input — it's usually labeled HDMI 1, HDMI 2, or HDMI 3 depending on which port you used. Your PC screen should appear on the TV within a few seconds.
If your PC doesn't have an HDMI port, you may have a USB-C, DisplayPort, or Mini DisplayPort instead. You can buy an adapter cable (USB-C to HDMI, DisplayPort to HDMI, or Mini DisplayPort to HDMI) for $10 to $25 at any electronics store. The adapter plugs into your PC, then the HDMI cable plugs into the adapter.
Once your screen appears on the TV, you can adjust the display settings in Windows. Right-click on your desktop, select "Display settings," and choose whether you want to duplicate your screen (show the same thing on both), extend it (use the TV as a second monitor), or show only on the TV. Most people choose duplicate for watching videos or presentations.
Using Miracast (wireless, built into Windows)
Miracast is a wireless standard built into Windows 10 and 11 that lets you send your screen to any TV that supports it. Most TVs made after 2015 have Miracast built in, though you may need to turn it on. Check your TV's manual or settings menu for an option called "Miracast," "Screen Mirroring," "Wireless Display," or "Cast."
To use Miracast on your PC, press the Windows key and the letter K at the same time. A panel will open on the right side of your screen showing nearby devices. Select your TV from the list. The first time you connect, your TV may ask you to confirm — select yes. Your screen should appear on the TV within 5 to 10 seconds.
If your TV doesn't appear in the list, make sure Miracast is turned on in your TV's settings, that your PC and TV are on the same WiFi network, and that your TV is within 30 feet of your PC. If it still doesn't work, restart both devices and try again. Miracast works best for watching video or presentations — it has a slight delay (1 to 2 seconds) so it's not ideal for gaming or real-time mouse control.
Using Chromecast (wireless, requires a device)
If you own a Google Chromecast device (a small stick that plugs into your TV's HDMI port), you can share your PC screen wirelessly. Plug the Chromecast into an HDMI port on your TV and plug its power cable into a nearby outlet. Make sure your PC and Chromecast are on the same WiFi network.
Open Google Chrome on your PC. Click the three-dot menu in the top right corner, then select "Cast." A list of nearby Chromecast devices will appear — select your TV. Your screen will appear on the TV within a few seconds. To stop sharing, click the Cast button again and select "Stop casting."
Chromecast is reliable and has minimal delay, making it better for gaming than Miracast. The downside is you need to own a Chromecast device (usually $30 to $50). If you already have one, it's one of the best wireless options available.
Using Apple TV (wireless, requires a device)
If you have an Apple TV connected to your TV, you can share your PC screen using AirPlay. Make sure your PC and Apple TV are on the same WiFi network. On your PC, read and install iTunes or the Apple TV app from the Microsoft Store (it's free).
Open the Apple TV app, click the "Watch Now" tab, then look for an AirPlay icon (usually in the top right or bottom right of the window). Click it and select your Apple TV from the list. Your screen will appear on the TV. To stop sharing, click the AirPlay icon again and select "Stop AirPlay."
Apple TV works smoothly if you're in the Apple ecosystem, but it's expensive ($99 to $199) and only worth buying if you already use other Apple devices. For PC-only users, Chromecast or Miracast is usually a better choice.
Troubleshooting common problems
My TV doesn't appear in the Miracast list. First, check that Miracast is turned on in your TV's settings — the exact menu location varies by brand, so check your TV's manual. Second, restart both your PC and TV. Third, make sure they're on the same WiFi network. If you're on a guest network or a 5 GHz network, try switching to the main 2.4 GHz network.
The connection keeps dropping. Move your PC closer to your TV or router — wireless connections work better within 30 feet. If you're using Miracast or Chromecast, try switching to a wired HDMI connection instead, which is more stable. If you must use wireless, restart your router and TV, then reconnect.
The screen is laggy or delayed. Wireless methods have a built-in delay of 1 to 3 seconds, which is normal. If the delay is worse than that, you may have WiFi interference — move your router away from microwaves, cordless phones, or other wireless devices. For gaming or real-time work, use an HDMI cable instead.
My PC has no HDMI port. Check what ports your PC has — common alternatives are USB-C, DisplayPort, or Mini DisplayPort. Buy an adapter cable that matches your port (usually $10 to $25) and plug it into your PC, then connect the HDMI cable to the adapter.

Frequently Asked Questions
Can I use screen sharing while my TV is showing cable or streaming apps?
Yes. When you connect via HDMI, Miracast, Chromecast, or Apple TV, it switches the TV input to show your PC screen. Your cable or streaming app pauses, but resumes when you disconnect. You can switch back and forth between your PC and your TV's normal input using the remote.
Does screen sharing work if my PC and TV are on different WiFi networks?
No. Miracast, Chromecast, and Apple TV all require your PC and TV to be on the same WiFi network to connect. If you're on a guest network, switch to the main network. HDMI cable is the only method that doesn't need WiFi.
Will screen sharing drain my PC battery?
Yes, slightly. Wireless methods use more battery than normal because your PC is constantly sending data to your TV. If you're using a laptop, plug it in while screen sharing. HDMI uses slightly less power than wireless methods.
Can I control my PC from the TV remote while screen sharing?
No. Your PC keyboard and mouse are the only way to control your PC while screen sharing. The TV remote only controls the TV itself. Some Chromecast and Apple TV apps have remote apps you can read on your phone, but they're optional.
What if my TV is too old to support Miracast or wireless methods?
Use an HDMI cable. Any TV with an HDMI port (made after 2008) will work. If your TV only has older ports like composite (red, white, yellow cables), you can buy an HDMI-to-composite adapter, but the picture quality will be poor. In that case, consider upgrading your TV or using a Chromecast device instead.
