Greetings Rolls-Royce,

Can the unstability you mentioned be reduced/eliminated by canceling the LCD display internal frame doubling (120Hz-->60Hz) ?

I recently bought a bunch of RF glasses from 3D-VIP (Consignia) for my new Optoma HD25e 3D projector, and I am very tempted to purchase a 3D Theater+ for the living room LCD (an older Sammy LN52B610 with internal frame doubling to 120Hz).

Cheers,

'nose

I tried that with our bedroom Sony LCD, and still had the instability. I believe the TV is modifying the picture's sync once the data stream enters the display's circuitry in order to manipulate it and add the interpolated frames for the "120 Hz" and "motion smoothing" operations, even with those functions off. Since the VIP and all other such components produce the 3D glasses sync before the TV gets the signal, there can be some divergence between the glasses and display. If your set actually fully turns off the internal processing, you probably wouldn't have the issue.
