Well there seems to be alot of disscusion about the 3ds screens im here to shed some light on this. So i made a reply to a post in a topic about the 3DS screens being a failure with some facts and perspective on how the 3d Screens work but this seemed to confuse the topic creator as i was not clear so this article is born.
Well think of it this way the DS has two screens and the 3DS has 3 (well not really but one displays as 2 separate images from one screen) one for touch input and two for stereoscopic 3D. Think about sound mono output is limited and stereo is superior because you have 2 ears and the speakers can only create so much sound so having 2 doubles the sound capacity and perception by the brain. It is the same with the 3DS There are 2 images generated each with there own separate detail and representation of whats going on in the 3d rendered game world. Just as you have two ears you also have two eyes which used in conjunction is vastly superior than one eye.
So to clear up this there is a misconception that because you can turn the 3d off that the 3DS resolution is only 400x240 but its actually is 800x240 just only while the 3D effect is on. The resolution is really 400x240 400x240 no thats not a typo i put it twice to put it into perspective there is a reason nintendo wants you to see it for yourself. Its hard to imagine that detail and depth in 2d video or still 2d images that only show half this perception. all the screens we've seen show half of what the 3DS outputs. yes those Beautiful games actually are even better than they all ready look and thats why people are so blown away by the 3ds its the depth.
wait a minute how does the 3DS do that you say well to quote tk_satrurn
Anywho just use your imagination and you will see why Game developers are excited to put there contend on Nintendo's system or wait to see it yourself.
Here is some raw info to put things in perspective
on the 3DS there are 96000px for each eye on a 3.53" screen thats 132.15PPI (pixels per inch)
a 480p tv is 21PPI on a 42" inch screen
a 1080p tv is 52PPI on a 42" inch screen
a PSP is 480×272 128PPI on a 4.3"

In contrast conventional stereo 3D requires half of the light emitted by the display to be used for each eye. Where each image is flashed one at a time to each eye using high speed shutters, reducing overall clarity. Not so with 3DS, it displays both images at once at reported locked 30-60fps.tk_saturn said:The 3DS has 2 screens, each eye will see alternating columns of the top screen. A parallax barrier will prevent the left eye seeing what the right eye sees, and vice versa. When you turn off 3D, the internal resolution of the 3DS will be Anamorphic 400x240. If the resolution was 800x240 with 3D off, then people at E3 would have seen a massive improvement in graphics with 3D off. This would be bad press for it's 3D which is it's main selling point, Nintendo wouldn't like that.
