Option 1: Use a Wi-Fi connection

The easiest way to cast your laptop display to your TV is via Miracast, if both devices support it.

Miracast is a wireless communication standard that permits transmission of video and sound over Wi-Fi rather than a physical cable. In other words, it acts like a wireless HDMI cable.

Most modern latops with Wi-Fi capabilities should support Miracast, as should most modern smart TVs. However, TV manufacturers often have their own name for each implementation of this technology. Here are just some of the most common:

Samsung

Smart View / AllShare Cast

LG

SmartShare

Sony

Screen mirroring

Roku

Screen mirroring

Hisense

Screen Sharing

To cast your laptop screen to a modern smart TV using Miracast, first ensure your TV's settings allow for it by navigating through its settings and looking for one of the above terms (for example, ensuring "allow screen mirroring" is ticked on a Roku device).

There are plenty of streaming devices, but few offer as extensive range of apps and channels as the best Roku devices.

Then, follow the steps below to cast your Windows laptop or MacBook to your TV. If you have an older laptop that doesn't support Miracast, you can buy a Wi-Fi adapter that does such as this one and plug it into your laptop, using it to connect and cast to your TV.

How to cast a Windows laptop to a TV

There are two ways to wirelessly cast a Windows laptop to a TV. This first way will be the most convenient if you might want to cast your laptop to your TV more than once. If "cast" is already an option in the quick settings tray, you can skip step 3.

  1. Ensure your laptop and TV are both connected to the same Wi-Fi network.
  2. Open the quick settings tray by clicking on the network or sound icon in the Windows tool tray.
  3. If there's no option to "cast", click the pencil button to edit quick settings, then click Add, select Cast, and click Done.
  4. Click Cast.
  5. From the list of displays, select your TV.
  6. If required, switch over to your TV's casting input source and/or accept the prompt on your TV to start casting.

Now, whenever you want to cast again, you can skip step 3 and launch via the quick settings panel straight away.

Alternatively, you can cast to TV by opening Windows Settings (right click Windows button -> Settings), selecting Display, and then selecting Connect next to Connect to a wireless display.

How to cast a MacBook to a TV with Apple AirPlay

Option 2: Connect directly via HDMI

Of course, not everything has to be done wirelessly, and there are still plenty of reasons to opt for a wired casting solution over a Wi-Fi one. Perhaps most importantly, a HDMI cable will probably provide better and more stable casting quality and latency than some Miracast connections, especially at higher resolutions where more data has to be transferred.

If your laptop doesn't have an HDMI port, it might support HDMI over USB-C, in which case you can connect via a USB-C to HDMI cable like this one, or use a USB-C to HDMI adapter like this one in combination with a standard HDMI cable.

For this reason, connecting your laptop to your TV via a HDMI cable is a great, simple casting solution. Simply plug an HDMI cable into your laptop's HDMI port at one end and your TV's HDMI port at the other, switch over your TV's input source to match the source the cable's plugged into.

Option 3: Use website, browser or app casting features

If you don't want to mirror or extend your screen but, for example, just cast a specific video onto one of your smart TV's streaming apps, then different websites, apps, and browsers will have different ways of letting you do so.

Most of the more popular streaming services should give you a way to cast videos on their platforms from another device to your smart TV.
