WiDi is quite a new technology so not all computers or televisions have it built in.
Currently, WiDi is only available on PCs running Windows 7 with specific Intel hardware. You can check the technical requirements on Intel's webpage:
If your TV doesn't have a built-in WiDi receiver you will need to purchase an external WiDi adapter. There are a number of these available from good electrical retailers.
Steps before connecting your WiDi:
Make sure you have the latest version of the WiDi software installed on your computer. This can be found here:
IMPORTANT: Install the drivers in the order given on the website.
Your computer should be within 20 feet (approx. 3 metres) of the WiDi receiver
Setting up the WiDi connection:
- If it isn't built in, connect your adapter to the TV. We recommend using HDMI for the best picture quality
- Select the channel your adapter is connected to
- Launch the WiDi software on your computer
- Scan for available networks until it detects the adapter. You may need to do this a few times.
- If you get a firewall alert regarding the software, give it permission
- If the software asks you to update, allow it
- Your TV will be displaying a numerical code. Enter this into the WiDi software on your computer
- Your computer's screen will now be mirrored on the TV
- For best results, use the WiDi widget to launch video and audio software. This will allow you to adjust things like aspect ratio if the image on the TV is not quite right.
Known WiDi issues:
- You may experience some lag between the images appearing on the monitor and the TV. For this reason, this method of connecting is not suited for gaming.
- Volume levels should be adjusted through the TV, not the computer
Some users have experienced issues where copy protected media, such as shop-bought DVDs and Blu-rays, will not play over WiDi. This was a DRM issue in earlier versions of the WiDi software. Updating ALL the WiDi programs, including display drivers, should solve this problem.
If you experience poor performance and are using a Windows Aero theme you have downloaded, try switching to one of the default themes. The downloaded themes sometimes cause a graphical conflict and slow down the system.
