Yes, that too.
Your post reminded me of the lock. The 3D device will work at 60 Hz exactly. Almost all the displays/projectors work at 60 Hz but they don't necessarily lock to 60 Hz. They take 60hz input and show at 59.99 (yeah, weird but it happens). With these displays, the picture starts okay, but over few minutes, the audio drifts and video lags behind by few milli-secs. So, if anyone wants to use the 3D VIP device, they need to be certain that their projector locks to 60 Hz.
