The HD142x and most newer DLP's use whats called triple flash for 24hz 3D. It will display each frame 3 times for each eye so that is 6 x 24 = 144hz. It has no FI so no SOE effect. 60hz 3D will play @ 120hz so this is why the old 120hz glasses will work for 60hz sources and not for 24hz sources thus the need for newer 144hz glasses.
