| Slimebeast said: Why is they all nneed 120hz? Why doesnt 60 frames per second is enough? I mean thats 30 frames for each eye, 30fps is enuff in most games. |
120hz/60hz (hz = cycles per second) and fps are two very different things. Most tvs flicker at 60hz, so those 30fps games are drawn with 2 frames (or 4 times for 120hz tvs) per cycle. This makes motion look more natural. If your TV flickered at the exact same rate as your 30fps game, you/most people would suffer pretty bad headaches. This is why most lights in your house flicker at 60hz.
A blueray (in NA atleast) is 24fps. For a 60hz tv, those images are drawn in a 3:2 ratio (first 3, second 2, etc per pass). 120hz takes away this problem by 120/24= 5 (a whole and easy number) so no need for 3:2 pulldown.
For 3D, as they are saying, 120hz will be split twice for both of your eyes. Either by 1 full signal of 1080p/720 @120hz or two 1080/720 signals @60hz (for each eye). Or if they use Checkerboard, they only need half of the full resolution per eye (still at 60hz)
