Connecting your PC to a TV wirelessly is a convenient way to enjoy films, stream content, play games or even present slideshows on a larger screen without dealing with cables. Whether you are using a Windows laptop or desktop, there are several ways to mirror or extend your display onto a compatible smart TV using your home Wi-Fi network or wireless display technologies.
This guide explains how to wirelessly connect your PC to a TV, what you will need, and how to ensure the connection works smoothly.
Why Connect Your PC to a TV Wirelessly
Wireless connections allow for more flexibility and less clutter. Instead of running a long HDMI cable across the room, you can cast or mirror your display directly onto a television using built-in tools like Miracast or streaming devices like Chromecast. This makes it easier to stream video, browse the internet or share media from your PC with friends and family on a larger screen.
It is especially useful for home entertainment, remote work, or classroom settings where mobility and ease of use are important.
Check Compatibility
Before starting, check if your PC and TV both support wireless display technology. Most Windows 10 and Windows 11 PCs have built-in support for Miracast, which allows screen mirroring over Wi-Fi. Many modern smart TVs from LG, Samsung, Sony and others also support Miracast.
If your TV does not support it directly, you can still connect using a Chromecast or Amazon Fire TV Stick, both of which support wireless casting from a PC.
How to Connect Using Miracast
If your PC and TV both support Miracast, follow these steps to establish a wireless connection.
Make sure both your PC and TV are connected to the same Wi-Fi network. On your Windows PC, press the Windows key + K to bring up the Connect sidebar. Your TV should appear in the list of available wireless displays. Click on your TV to connect. After a few seconds, your PC screen will appear on the TV.
You can also go to Settings > Display > Multiple Displays to choose whether you want to mirror the screen or extend it to use the TV as a second display.
On your TV, you may need to enable screen mirroring or wireless display mode depending on the model. Check your TV’s input options and make sure it is ready to receive the signal.
How to Connect Using Chromecast
If you have a Chromecast plugged into your TV, you can wirelessly cast your desktop or specific browser tabs.
Install the Google Chrome browser on your PC and make sure your PC and Chromecast are on the same Wi-Fi network. Open Chrome, click the three-dot menu in the top-right corner and choose Cast. Select your Chromecast device and then choose whether to cast a tab, a video file or your entire desktop.
This method works well for video streaming or showing web pages, but may have slight lag for fast-moving games or animations.
How to Connect Using an Amazon Fire TV Stick
The Fire TV Stick also supports screen mirroring, but it requires a few extra steps.
First, hold the Home button on your Fire TV remote and select Mirroring. On your PC, press Windows key + K and select your Fire TV Stick from the list of available devices. Once connected, your PC screen will display on your TV.
This method mirrors your full desktop and works well for presentations or basic media playback.
Troubleshooting Tips
If your PC does not detect the TV, check that both devices are connected to the same Wi-Fi network. Also check that your PC’s wireless display driver is up to date by going to Device Manager and updating your Network Adapters and Display Adapters.
In some cases, your PC may not support wireless display. You can check this by pressing Windows key + R, typing dxdiag and opening the DirectX Diagnostic Tool. Click Save All Information and open the saved text file. Look for Miracast: Available under the Display section.
Final Thoughts
Connecting your PC to your TV wirelessly is a practical way to enjoy media on a bigger screen without cables. Whether you are using Miracast, Chromecast or a Fire TV Stick, each method allows you to mirror or extend your display with minimal setup. As long as both devices are on the same network and compatible, the connection should be fast and reliable. With just a few clicks, your living room can turn into a personal cinema or a workspace with room to breathe.
