"120Hz Frame Sequential 3D for
Resolutions Up to 720p"
Does this mean that we aren't actually going to get 1080p to each eye for 3D Blu Ray? If so, then why is everybody so hyped up over this "1080p" 3D projector?
It means you can basically send it a 120hz 720p signal, where each 720p left eye is one frame and then the right eye is one frame within 120hz. This is the signal most 3D 720p projectors can handle outside the 1.4 spec.
Modes within the 1.4 spec are:
For movie content (3D blu-ray):
•Frame Packing (Full HD 3D or FHD3D) ◦1080p at 23.98/24Hz with each frame having resolution 1920×2205, containing lossless sub-frames for the left and right eye.
For game content (I think PS3 does this):
•Frame Packing (2 – 720p frames packed in over/under or top-and-bottom configuration) ◦720p at 50 or 59.94/60Hz
For broadcast content (think cable and satellite):
•Side-by-Side Horizontal 3D ◦1080i @ 50 or 59.94/60Hz
•Top-and-Bottom (Over/under) 3D ◦720p @ 50 or 59.94/60Hz
The projectors has to have a computer processor onboard to handle all these signals and feed them to the projector. Most 720p projectors (and some 1080p) require an external processor--and many use a computer to do this, but usually a computer does 120hz frame sequential only. And a another type of 1.4 processor is required like the 3D-XL to handle the full 1.4 spec.
