Considering the upper screen is really 800 x 240, when you turn off the 3D there is no need to split the image, so technically it could display the non-3d image in twice the resolution.
Any word if the 3DS will actually do this, or just scale down to 400 x 240 even in non-3d mode?

...I don't think that's how it works. I would assume that all three images (both 3D and 2D) are displayed at the same resolution. The 3D works BECAUSE there are two images.

I read somewhere that it scales down.

Electrium: The upper screen is 800 x 240, but when playing in 3D, it technically produces two images, giving each eye a slightly different 400 x 240 image. But when the 3D is turned off, there would be no need to have two 400 x 240 pics, so, technically, the 3DS could use the whole 800 x 240 screen to display one, higher res, pic.

You're both right and wrong.

The screen only ever produces a single 800 x 240 image on the screen. One eye will only see one 400 x 240 image and the other a different 400 x 240 image.

When the 3D is off the eyes see two identical 400 x 240 images which makes it look like one. You can not see the full 800 x 240 with one eye (which is what is needed for a higher resolution non-3D image.

I see, so the 3DS still renders two pictures, just identical?
What makes you so sure it does that?

Because the 3D slider doesn't change the actual physical screen. The screen is always attempting to block 400 x 240 pixels from one eye, while the receives another image of the same size.

The slider effects what each image is. Lowering it makes the images have more similar angles by the camera. Because the screen can't be physically changed there's no way for the other eye to see the other 400 x 240 pixels in proper use.
