Toshiba Laptop to TV Wirelessly: How to Connect and Fix Detection

By Freedom251 Team · · 3 min read

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

To connect a Toshiba laptop to a TV wirelessly, put the TV in its wireless display or screen-mirroring mode, then press Windows key + K on the laptop and choose the TV. This uses Miracast, so it works only if both devices support Miracast and the TV’s receiving feature is enabled. A Toshiba brand name alone does not guarantee compatibility.

Check whether your laptop and TV support wireless projection

Windows uses Miracast for this kind of direct wireless display connection. Microsoft advises checking that the PC supports Miracast, Wi-Fi is on, and the TV supports Miracast with its wireless display feature enabled. See Microsoft’s guide to screen mirroring and projecting and its wireless display troubleshooting steps.

Find the TV’s receiving mode

On the TV, look in the source, network, or screen-sharing menus for a label such as Wireless Display, Screen Mirroring, or Wireless Projection. Labels and menu locations vary by model. A Toshiba TV manual for a particular model also uses the name Smartview and instructs users to set the TV to a wireless network connection before screen sharing; check your own model’s manual rather than assuming every Toshiba TV has the same menu. Toshiba’s support page confirms Wireless Display on supported sets, not on every model: Toshiba TV support and the model-specific Toshiba TV manual.

Check the laptop

Make sure Wi-Fi is turned on. Microsoft’s Windows guidance describes Windows key + K as the shortcut for checking for and selecting available wireless displays. If you are unsure whether your Toshiba laptop supports Miracast, consult its model documentation; the available Toshiba laptop manual covers only the named Z30-C, Z30t-C, Z40-C, and Z40t-C models, not every Toshiba laptop: Toshiba Z-series laptop manual.

If the TV does not support Miracast

A Miracast adapter can add wireless receiving to a TV that lacks built-in Miracast, provided the TV has an available HDMI input and the adapter has a suitable power source. For Microsoft’s Wireless Display Adapter, connect it to the TV’s HDMI port and USB power, switch the TV to that HDMI input, then connect from Windows with Windows key + K. Follow Microsoft’s adapter setup instructions.
