How to Connect a Laptop to a TV Wirelessly

10 minutesEasyPublished September 7, 2026

Wireless screen sharing works when both the laptop and TV support the same casting technology, such as Miracast, AirPlay, Chromecast/Google Cast, or a compatible streaming device. Start by putting both devices on the same Wi‑Fi network.

The Quick Answer

Connect the laptop and TV to the same Wi‑Fi network, enable the TV’s screen-mirroring or casting mode, then use the laptop’s built-in cast/display control to select the TV. If the TV does not appear, restart both devices and verify they support the same wireless display standard.

Safety note

Only install casting software from trusted app stores or the device manufacturer.

Step-by-Step

  1. Step 1: Check what the TV supports

    Look in the TV settings or manual for AirPlay, Miracast, Chromecast/Google Cast, screen mirroring, or wireless display support.

  2. Step 2: Connect both devices to the same Wi‑Fi

    Put the laptop and TV or streaming device on the same home Wi‑Fi network.

  3. Step 3: Turn on the TV’s casting or mirroring mode

    Open the TV input or connection menu and enable screen mirroring, AirPlay, casting, or wireless display as appropriate.

  4. Step 4: Open the laptop’s display or cast control

    On Windows, use the Cast or wireless display control. On a Mac, use Screen Mirroring/AirPlay when supported.

  5. Step 5: Select the TV

    Choose the TV or streaming device from the list and approve any connection prompt or code.

  6. Step 6: Fix it if the TV does not appear

    Restart both devices, confirm they are on the same Wi‑Fi network, and verify they support the same casting standard.

  7. Step 7: Use a cable when delay matters

    For gaming, live presentations, or situations where wireless mirroring lags, an HDMI connection is usually simpler and more reliable.

Tips

  • Put both devices on the same Wi‑Fi network before troubleshooting.
  • For video streaming, casting directly from the streaming app can work better than mirroring the entire desktop.
  • Use HDMI instead if you need the lowest delay for gaming or presentations.

Common Mistakes

  • Assuming every smart TV supports every casting standard.
  • Trying to pair the TV through Bluetooth instead of the correct screen-casting feature.
  • Troubleshooting the laptop before checking whether the TV’s mirroring mode is enabled.
