To cast your laptop to your TV wirelessly, make sure both devices are connected to the same Wi-Fi network. On Windows, press Windows + K and select your TV from the list of available devices. For Mac users, use AirPlay if your TV supports it. You can also use streaming devices like Google Chromecast, Amazon Fire Stick, or Apple TV—just open Chrome, click on the three dots (⋮), choose "Cast," and select your device. It’s an easy way to enjoy your laptop screen on a bigger display without any cables.
