If you want to quickly sync a laptop's screen or connect your game console to an HDTV from a few feet away, generally you need an extra-long HDMI cable. There's a much better way, however, and that's the Gigabyte SkyVision WS100.
This is a kit of two adapters that can connect to each other using WHDI wireless technology, allowing you to forgo the long physical HDMI cable that generally connects a playback device and an HDTV. And in my testing, the quality of both video and audio of the wireless connection was virtually the same as when you use a cable for the connection, making it a great accessory for those who want to cut down on cables and have more flexibility in terms of equipment placement for their home entertainment systems. The kit also comes in handy for offices, in case you want to quickly connect a laptop to a big screen for presentations, gaming, or what have you.
The kit is not perfect; it works only with HDMI-ready devices, so you can't use it to connect a computer without an HDMI port to a TV. Also, both of the adapters require external power, and, finally, at $150, it's rather expensive.
That said, the Gigabyte SkyVision WS100 is still one of the best among its peers and is definitely worth the investment.
Design and ease of use
WHDI is one of a few existing mainstream wireless display technologies, and is the direct competitor to Intel's WiDi. Both technologies allow users to wirelessly connect a supported device to a big-screen TV and deliver audio and video signals, just like when the device is connected to the TV using an HDMI cable, with the same signal quality.
WiDi has the advantage over WHDI since it's now a built-in feature on many laptop computers. WHDI, which is developed mainly by Amimon, however, generally offers better signal quality with virtually no lag detectable by human eyes.
Like with all wireless technologies, unless your devices have built-in support for it, you'll need adapters. The Gigabyte SkyVision WS100 is made for those situations in which both the HDTV and the playback device, be it a laptop, a game console, or a Blu-ray player, don't support WHDI. As long as both devices have an HDMI port, you can use the Gigabyte SkyVision WS100 with them.
As I mentioned earlier, the Gigabyte SkyVision WS100 comes with two adapters: one is the receiver that connects to an HDTV; the other is the transmitter that connects to the playback device.
The receiver is a small, squarish unit that measures 3.7 inches by 3.2 inches by 1.3 inches. It has one HDMI port and one Micro-USB port. You do need a short HDMI cable (included in the package) to connect the receiver to an HDMI port on the TV. After that, connect the receiver to the power using a standard USB power adapter (also included), and one end of the connection is ready.
