My first thread did create a lot of controversy, and for good reason. I forgot one main component. I forgot to discuss PPI. I corrected this in the original post, but I figured many people would not go back to read the main post, so I figured I would create a new thread to discuss this and apologize. I also want to give a huge thanks to Wolfmanz51 who corrected me. To fully understand why the 3DS resolution is more then good enough we have to understand Pixels Per Inch. To best understand PPI, you first need to know the resolution of the product you are looking at. -In the case of the 3DS the resolution is 400x240. -The total resolution is 96000. - Now all 96000 pixels are going to be squeezed into a 3.5 inch screen. - If you were to see how many pixels would go for each inch you would need to do an advanced calculation. Lucky for us, this site exists which does these calculations for us. In this case the 3DS has a PPI of 133.28. To put this in comparison, a 50" 1080i/p TV only has a PPI of 43.71. So the 3DS will have nearly 3x as many pixels per inch then a 50" 1080i/p TV. This is more then enough to make anything look great if the poly count is high. If Nintendo gave us 720i/p, the PPI would be 419.6, which would be ridiculous. That would be nearly 10x the PPI count of a 50" 1080i/p TV. Taking all of this into account, I still think that the 3DS will still need a 4.9 inch screen to give us a good 3D experience. Now, I know that a good 3D experience is subjective. I personally am under the belief that 3D looks best when it engulfs your line of vision. You don't feel like your looking into a 3D box, you feel like your in the action. Looking into a 3D box maybe good for some of you, but most 3D TV reviewers criticize 3D TVs because it doesn't make you feel like you are part of the action because the screen is not big enough to do that. In my original thread I showed how a 4.9 screen with a 10 inch viewing distance can emcompass the same field of vision as 70" TV at a 12 foot viewing distance. To me a 70 inch at this distance provides the feeling of being in the action that would be good for movies and gaming. So the new question becomes, now that we know that we don't have to push out 720p for the DS to look good, should Nintendo try to squeeze in a 4.9 inch screen. Also, what do you think a good 3D experience is? Would looking into a box be enough for you, or do you want to feel like your part of the game? A good way to think of this, is the MGS demo. In the beginning you see the grass go by. If the screen was bigger, the grass would engulf more of your field of vision, and that 3D would feel more real. Or does this not matter to you? Do you not mind 3D that feels like looking into a diorama?
