3 reasons why to NOT buy a new 3DTV for gaming.

Just to be thourogh: Here is the bandwidth formula (one of many but its the easist to approximate)

SF = [(TP x Vt)/2]3

SF = Signal Frequency (or bandwidth)

TP = total pixels

Vt = vertical refreshrate

Nice. This is pretty handy. You are quite a mathemaitician... :)

So the current scenario is:

- 3D 1080p@60 requires more bandwith than HDMI 1.3/1.4 offers (372 Mhz)

- But due to frame packing method which the 1.4 standard introduced to reduce bandwith, HDMI 1.3/1.4 chips can indeed do 1080p@60hz in 3D in theory (297 Mhz)

- However the 3D TVs currently on sale do not have fast enough HDMI chips to do 297 mhz of bandwith hence they don't support 1080p@60  hz in 3D

- Because 1080p@60 hz is not a manditory standard for these new TVs, and the TVs are able to do 1080p@24hz for bluray, they are able to get away with putting Full HD 3D on the box.

 

It looks like I dodged a bullet when decided to to buy these TVs yet. I say within a year max, we will have new 3D TVs which can do 1080p@60hz...

Also, HDMI 1.2 CAN (bandwidth AND bitrate) support HD movie 3D (1920x1080@24hzx2) = 149.3 MHz.  Digital Downloaded 3D movies Inc on both PSN and Xbox live?

-They must be able to transmit up to 340Mhz, but they do not have to receive 340 Mhz (so the PS3 can push the bandwidth maximum, but the Tvs cannot receive it, because they do not have too)
