I like this switch more than the software solutions of many commercial shutterglasses controllers. The controller will just sync to it. No questions asked. LCD-BIOS doesn't need any parameters anymore. Please read the Drawback section for possible problems.
Most manufacturers think so.
Another drawback is the fact that you always have to set stereo orientation manually at startup and whenever the screenmode is changed. Most manufacturers think so. There are no sync-doubler or line blanker capabilities yet. In theory stereo is reversed each time the controller misses a sync. I don't know how often this happens.
