How to connect a laptop to TV wireless - Expomata

Connect a laptop to TV wirelessly

If you can't or don't want to have a wire between your laptop and TV, another option is to go wireless.There are various options here depending on your laptop's capabilities since a few laptops have a built-in wireless system called WiDi (Intel Wireless Display) which works with a compatible receiver such as Netgear's Push2TV.

There are also wireless systems which plug into the HDMI port on your TV and laptop (possibly the USB port on your laptop), sending the video wirelessly. These aren't generally cheap, though, and most wireless video systems have a hit on video quality and can also introduce a mismatch between video and audio.

If you want to transmit full HD 1080p video, expect to pay around £200-300 for a transmitter and receiver kit, such as the £199 One for All SV1760 from Maplin. There's also the IOGear GW3DHD Kit which works to around 100ft (rather than 30) but costs quite a bit more. 

Google Chromecast

For most people the best wireless solution is to buy a Google Chromecast which costs as little as £30. This HDMI dongle plugs into your TV and connects to your Wi-Fi.

The devices has the ability to cast a tab of your choice in Chrome so it appears on the screen using the built-in cast feature. You can then visit websites, show photos and even watch video. Find out how to setup and use a Chromecast.
