Wireless Display - What is behind it?
Intel Wireless Display (short WiDi) is a technique with the help of which you can transfer your current image wirelessly to another device. So consider, for example, presentations or Videos on your TV.
- You can use WiDi if your Laptop or Tablet at least an Intel Core processors of the 3. Generation and an Intel n-Wi-Fi-module. Of course you will also need the appropriate driver for your device.
- First of all, your Wi-Fi module needs to support the Standard: In some devices, the receiver is already installed in the TV. Alternatively, they are upgrading the Standard with an Intel Adapter itself.
- So far, the Intel WiDi works only on Windows 7 and 8.
- With WiDi 1080p video signals including the 5.1 sound can be transmitted. Also for the second Version of the HDCP copy protection, it Blurays, and DVDs can be so transferred.
- Since WiDi is only supported by a very small group of devices, has Intel support decided to the more common Standard Miracast to. Since Miracast and WiDi are technically very similar, this is only a Software Update is required.
