600HZ Sub Field is by no means faster that 120hz/240hz – it is regular 60 hz split down into 10 subfields – so it changes 1/10 of its pixels 600 times a second, or Each pixel 60 times. It creates a more fluid (yet Spaced in scene changes) images. 480hz does this in groups of 8.

HDMI 1.4 is a new standard – it governs a Minimum operation spec of the required HW/SW. This DOES NOT mean that all the Cables/Equipment you currently own is instantly Obselete – it just does not Comply anymore. It may (or may not) still offer the desired effect you require for your setup. Most of the cabling i own is 1.3 spec, but not certified – and its works fine, and from what i have seen on the web, 1.4 is still 10.2Gbps (although some say 20) – it’s for that fact that the major enhancement, 4K Video (4096×2160p24) can ONLY be 24hz, cause any higher goes over the bandwidth availability. the Wiki even says 1.3 cabling can support everythin of 1.4 but the ethernet channel that is introduced in 1.4.

Also the PS3 WILL be upgraded to HDMI 1.4 Via a firmware Update, as will the XBOX360 – from what i have read.

The Thing i still don’t get is Why the 3D movies have to be run at 100/120 hz – when all video is kept at 24hz, or upconverted to 50/60 hz – so in theory, the fact that 24hz camera is more than enough for a theater to supply us 2d, and 2 of those cameras can supply us with 3d, why wouldn’t a 24hz signal + 1(or 6) frames x 2 be good enough to provide us with 3d – 50/60 hz is more than twice the original 24 hz, and we are only working with 2 eyes and 2 cameras. i understand that the theatre can overlay these signals, whereas a tv can only Show one frame at a time, but….

Hold up, i think i am answering all my own questions here – As said Before by GURU – the signal flickers, so obviously the eye is not fast enough to see 1/24 images per second, but gets lost with 2/48 images, evey second frame makes up an image for each eye – so each eye would only see 24 frames for .5 of a second each (total). This will also happen in the faster rates, but 4/96 images per second means that each eye has half the time between refreshed images – and 100/120 is the regular video standard upgrade from that point (25/30 p – 50/60 i/p – 100/120 p)

The other solution to this problem would be to interlace the images – using sub fields to split the video so that both images are on screen at once – the problem here is as to how the video can show 2 differently polarised images on alternating scanlines. this could be run progressively at 50/60hz – and theoretically reduce flicker – but i’m no expert – i guess they would have looked at this already.

My new question is how does polarisation work on an HDTV. Thank you

You will be able to play 3D Blu-ray discs in glorious 2D without a 3D HDTV.

Sony did not respond when I asked that question in a email. We may have to wait until CES for the “official” answer.
