Ways to Cast from PC to TV

• Using Miracast – A wireless standard built into Windows 10 and many smart TVs.
• Chromecast built-in – Casts Chrome browser tabs to TVs with Chromecast.
• Roku streaming stick – Uses Miracast to mirror screens to Roku devices.
• Apple TV Airplay – Streams content from Mac/iOS devices to Apple TV.

Let‘s explore how each of these casting methods work…

Casting using Miracast

Miracast is a wireless display standard that lets you mirror your Windows 10 computer‘s screen directly to any Miracast-enabled smart TV or device.

According to Microsoft, Miracast provides smooth, wireless HD video and audio streaming without the need for an internet connection. It uses Wi-Fi Direct technology to create a peer-to-peer connection between the devices.

Here are the steps to cast from a Windows 10 PC to TV using Miracast:

1. First, ensure your Windows 10 laptop or computer supports Miracast. Go to Settings > Devices > Bluetooth & other devices and see if ‘Wireless display‘ is listed.
2. On your smart TV, locate the Miracast option in your TV‘s settings menu and enable it. It may be labeled Wireless Display or Screen Mirroring.
3. Now go back to your Windows 10 PC and open the Action Center by clicking the Taskbar icon. Click Connect > Wireless display.
4. You should see your TV listed. Simply click on it to connect your PC to your TV via Miracast.

Once connected, whatever is on your PC screen will be cast to your TV. Miracast provides full HD 1080p quality casting and minimal lag.

Using Chromecast Built-in

Many smart TVs and streaming devices like Android TVs now come with Chromecast built-in. This allows you to cast content from your Chrome browser to your TV.

To cast a Chrome browser tab from your computer to your Chromecast TV:

1. Ensure your computer and TV are connected to the same Wi-Fi network.
2. Open the Chrome browser on your computer. Click the Cast icon in the top right corner > Cast desktop.
3. You‘ll see the Chromecast devices on your network listed. Select the Chromecast device name that corresponds to your TV.

Chromecast will now display your Chrome browser tab on your TV screen. Keep in mind Chromecast only casts your Chrome browser, not your entire Windows desktop.

Using a Roku Streaming Stick

If you own a Roku streaming player, you can easily cast your Windows 10 computer screen to your TV using the device.

According to Roku‘s website, your computer will connect to the Roku player via Miracast to mirror your display. Here‘s how to set it up:

1. Connect your Roku streaming device to your TV and connect it to the same Wi-Fi network as your computer.
2. On your Windows 10 PC, open the Action Center > Connect > Wireless display.
3. You should see your Roku streaming player listed. Select it and click Connect.

The Roku will now cast a mirror image of your entire Windows 10 desktop in full HD quality. This provides a simple way to cast videos, games, photos and more from your PC to TV.

Using Apple TV AirPlay

If you own an Apple TV, you can use AirPlay to wirelessly mirror your Mac‘s screen or stream content from your iPhone or iPad to your TV.

According to Apple, AirPlay provides low-latency streaming at up to 4K resolution (on the Apple TV 4K).

To cast your Mac‘s display, go to Control Center and select your Apple TV as the AirPlay device.

On an iPhone or iPad, swipe up from bottom and tap on Screen Mirroring, then select your Apple TV.

Casting using Third-Party Apps

There are also dedicated apps you can use to wirelessly cast your computer screen to smart TVs:

• AirScreen – Casts Windows/Mac PCs to smart TVs.
• LetsView – Allows screen mirroring computer to TV.
• ApowerMirror – Casts Android, iOS and computer screens.

These apps work by creating a direct peer-to-peer connection between your computer and TV using Wi-Fi.

To use them, simply install the app on your computer and TV, connect both devices to the same Wi-Fi network, then select your TV in the app to cast your display.

Apps like AirScreen have very low latency, making them great for casting video and gaming content from your computer.

Comparing the Main Casting Methods

Here is a comparison of some key aspects of the main casting technologies:

Casting Method	Latency	Resolution	Computer Support
Miracast	Low latency	Up to 1080p HD	Windows 10 devices
Chromecast	Ultra low latency	Up to 4K UHD	Chrome browser only
Roku	Low latency	Up to 1080p HD	Windows 10 devices
Apple TV	Low latency	Up to 4K UHD	MacOS and iOS devices
Apps like AirScreen	Ultra low latency	Up to 4K UHD	Windows, Mac, Android, iOS

As you can see, each technology has its own benefits depending on your setup and needs.

Tips for Choosing the Right Casting Method

Here are some tips to consider when deciding on a casting method:

• Check compatibility – Ensure your PC and TV work with the casting technology.
• Consider latency – For gaming, AirScreen has minimal lag.
• Think about limitations – Chromecast only casts Chrome, not full desktop.
• Determine resolution needed – Roku and Miracast cap at 1080p HD.
• Think about devices you own – Use Roku if you have one, AirPlay if you have Apple TV.

For most situations, Miracast provides the simplest casting solution since it‘s built into Windows 10 and many smart TVs. But for lowest latency gaming and 4K casting, third-party apps like AirScreen are your best bet.
