Ssenkahdavic: "They call it top/bottom (one is on top of the other) and together they equal 1920x1080p (it does not say anywhere it is per eye," Well, look at Figure 8-6 3D structure (Top-and-Bottom), it shows L on top, and Ron bottom! Am I, or are you, missing something? Which brings us back to my question, how can they call this a 1080p mode, when it's just 1920x540?
I'm totally aware of what 60hz means and 60fps means, your totally missing my point. I know what interlacing is, I know what FPS is, and I know what monitor refresh is. Your stating the obvious. If you do a timedemo in a game it removes the 60fps lock and runs the engine at full speed to give you the maximum average framerate that the engine can put out, and yes it looks like a speed up movie. This is all common knowledge. My point was this, most console games run at 30fps at 720p, if they can at all, and only a handfull have higher framerates/resolutions, SO, a tv that can only accept 1080p at up to 30hz is fine, most console games could not do that anyway!

A good few people on these forums (and basically everywhere else) thinks of those two as the exact same (refresh vs fps) and for some reason it just irks me. Glad to see you are not one of them (tho could have saved me a good bit of typing had I know it :) You would be surprised how un"common" knowledge it is (tho it should not be)
They call it 1920x1080p because the final product (what you see in 3D) IS 1920x1080. Try this out. next time you are at a 3D movie, close one of your eyes. What do you see? You see a 2D image in the exact same resolution as the full feature (just without the 3D effects) I am betting when we get Top/Bottom 1080p in 3D, and you close one of your eyes, you will see the same 1920 horizontal, but you will only get half of the visual data out of the vertical. Your left eye see's 1920x540 on the top and the right on the bottom, but we do not see with only one eye, so in reality we are seeing both added together (just like how the human eye works).
It is just like Checkerboard 3D. In that method if the final product is 1920x1080, you are really only seeing 960x540 PER eye, like this:
12121212
21212121
(1 = left 2 = right) Our brains are designed to function this way normally (adding things from right and left, front to back, etc to get a total) This does not mean that it cannot work other ways (why pirates can function with only one eye :)
the final product IS 1920x1080, even tho the data sent to each eye is only half of that (both vertically and horizontally). Make sense? Top/Bottom uses this same format, just in a different way (but our brain is smart enough to put it together...atleast for MOST people)
Now, with Framepacking (having 2 full 1080p signals for each eye) you will end up with more overall data at the end (double top/bottom). This would be something siimalar to the different between 720p and 1080p. The more data there is avalable, the better the quality of the picture is (whether you can see it or not does not matter, it is just the fact that it IS better)
