It seems like switching between two signals should be instantaneous, but that's not always the case. In fact, depending on your setup, you might have as much as a ten second wait for your new signal to show up.
We've been waiting a while for wireless high definition setups to get to the point where they work well and don't cost an arm and a leg. And if IOGEAR's Wireless HD Kit is any indicator, we'll be waiting a while on the cost front.
If you've ever tried getting a standard laptop or netbook to send video to your TV and look good, you've probably run into the problem of outputs. You'll usually have a VGA out, and that only satisfies if you don't mind making some sacrifices to video quality.
Ah, the dream of living in a wireless world. No clutter behind the set, no need to run cords through walls or under the carpet. Wireless HD has been "on the way" for a while now, and as video technology advances further, wireless technology gets farther behind.
