This is a very good read on why 3D (1080p@24h w/o framepacking or 1080p@>24 w framepacking) works on the PS3 (that has HDMI 1.3 not 1.4)
"For a device to be rated as HDMI 1.4 requires it support a framepacked (two frames and meta data) 1080P and 720P signal. The TV takes the two frames and displays them at 120Hz (or faster) so with framepacking from the source you have two sequential frames in the time it takes for one 60Hz frame. The shutter glasses alternate turning (on-off) (off-on) at this rate (120Hz). This results in very little flicker and with good glasses almost no reduction in brightness or contrast. The framepacking method can vary. A device can support some of the HDMI 1.4 required standards but can not call itself compliant. Framepacked= two 3D (both eyes views) frames are packed into the timing window of 1 2-D frame (24-60Hz)."
"The HDMI 1.4 source device outputs a 60Hz or less video signal. When 3-D is active the framebuffer in the PS3 doubles in size and two frames are packed into, (timing) at double the transfer rate, the timing window that represents the 60-24 Hz frame rate associated with TV. The HDMI 1.4 TV recognizes this and pulls the two frames out of this "window" and displays the two frames alternately at 120Hz resulting in two 60 HZ (right and left) images for 3-D appearing to occur simultaneously because of persistence in the eye. The double 1080P resolution also supported by HDMI 1.4 is possible because the frame buffers in a HDMI 1.4 device have to be twice as large for 3-D so why not make these buffers available for double res if you are not doing 3-D. "
Oh well. I will be enjoying playing everything on my Mitsu DLP anyway (3D and all), just waiting for them to finally offer the damn bundle w/glasses.
