How Netflix Works
Netflix provides two distinct services, as of 2011. You can opt to have physical DVDs shipped to you or you can watch videos instantly over the Internet. Of course, you can always subscribe to both services. To watch videos instantly, you must use a computer with a Wi-Fi connection, a TV with a Wi-Fi connection or an Internet-ready TV accessory, such as a Wii or a PlayStation 3. To use Netflix on the Wii, you must be a subscriber to Netflix Instant.
Picture Quality
The Wii does not provide high-definition video quality -- even for its games. As a result, the quality of the streaming videos from Netflix can suffer. Usually, most viewers don't notice a significant problem. However, if you have an HD TV and are used to seeing crisp videos, you may notice problems with picture quality, including the brightness. Despite the Wii's limitations, though, you may be able to improve the brightness and quality of the videos.
Internet Connection
One of the most common problems with Netflix streaming videos on the Wii is the user's Internet connection, according to Nintendo's customer support. When the connection is slow, the video cannot download as rapidly as necessary, which can result in a fuzzy or blurry picture. Make sure that you are using an appropriate Wi-Fi connection -- DSL, cable or fiber optic. Dial-up is too slow, and most cellular or satellite connections can provide poor quality as well.
Other Solutions
The Wii comes with a composite cable to transfer video signals to the TV. This type of cable provides a lower quality video feed than component or HDMI cables. Purchasing a Wii-compatible component cable can significant improve the brightness and quality of streaming Netflix videos, according to Eric Taub of "The New York Times." In addition, you can always adjust your actual TV settings to compensate for issues in the video. Note, however, that some videos may have just been poorly filmed.
