I had a circuit lying around for this for a long time (a small box that allows the user to program a certain offset and eye opening time from a sync signal), which worked great with this. This can be used to hook up a phototransistor and get sync to the refresh times of the monitor, which can then be used to trigger shutterglasses on. I have tested this with various games and Tridef's 3D driver, including their media player. If so, it will render a small shutter mark over the application window in the corner of the screen. There I am working on a driver that intercepts Direct3D 9 calls from applications/games, and detects when they go into AMD's HD3D display mode. So the project has moved into a very different direction.
