The 3DS 3D screen looks bad in 2D

    I also picked mine up pretty early (ambassador 3DS, but not launch day), and mine doesn't seem that yellow to me. I haven't compared it side by side with a newer one, I've just gone by pictures and possibly just rumors on the net. Mine does have the issue of leaving lines on the top screen though. I've been thinking of picking up some rubber feet/bumpers to keep it from closing all the way. This is the image I was thinking of, but couldn't find in my first post

    I use 3D all the time except when my battery is low and I don't have a charger.

    I'd use the 3D but I can't see it correctly, no matter what I do.

    Anyway, about what the OP said, I see what he's talking about but I NEVER cared for it, because I play, I don't try to find flaws with everything I touch.

    Because it's not two screens, and they're not overlapping. If it had two screens, then you'd have to double both X and Y, from 400 to 800 and 240 to 480 (so 400x240 becomes 800x480).

    But why does Nintendo say it's only 800x240? Twice as wide, but same height? How can that be? Well, if it was square pixels, it'd be a pretty long screen. Long width, low height. So squish the pixels into rectangular ones and you get... oh, now that looks more like it. Add a parallax barrier on top that obscures every other pixel length-wise and you get half width, which puts us at 400x240.

    So that not overlapping thing you're seeing, it's actually pixel gaps. Vertical pixel gaps. You were expecting square pixels. It's probably the scanlines some people are talking about.
    See: http://en.wikipedia.org/wiki/Parallax_barrier
    Rectangles, because that's how the 3D works with parallax barriers.

    Also:
    Some people are not aware that there are any aliasing effects at play. If they are dumb for that, then I weep for humanity. But is it really aliasing, or are the rectangular pixels just pairing up to form a square pixel? Hmm?

    So how do you explain the absence of these scanlines in 3D mode on the lowest depth?

    Here is a nice description of the problem from a gamefaqs user: http://www.gamefaqs.com/boards/997614-/61410963

    I use my 3DS in 3D during gameplay because it makes the screen wider.
    Not physically wider, but because a frame is displayed for each eye at different positions, it 'appears' wider.
    As for the 2D mode, the aliasing is great, but in some situations it appears to blur the game play.
    Personally I think the graphics look better in 2D mode because it is higher res and the pixels are less noticeable.

    As for "fix this Nintendo" Why fix something that does not need fixing, I just wish there were some games that did not use the 3D and instead used all the 3DS' screen pixels to achieve better graphics.

    How is 2D mode higher res if the resolution is lower than in 3D mode? Pixel less noticeable? Preciously because 2 pixels are "compressed" to one in 2D more, you notice them more because as you said the picture is a bit blurry.

    Yes, just because something is higher res, It does not mean that it is clearer.

    I don't think you know what higher res means.

    What I mean is, you can take a blurry photo on a 16 megapixel camera but it is still the same resolution as a clear photo on the same camera.
    Some 3DS software just looks blurry in 2D because It is not well optimized for 2D.

    EDIT: I am and have been referring to Pixel Resolution

    Perhaps you mean pixel density? High Res means by definiton a higher resolution. 3D mode: 800x240. 2D mode: 400x240

    I've always thought of it this way, in 3D mode there are 2 400x240 images, 1 for each eye.
    In 2D mode there is one 800x240 image with lower spatial resolution.

    Nope, in 2D mode there is only a 400x240 resolution because every 2 horizontal pixels count as one pixel. Perhaps you didn't read this quote?

    So if the 3DS is still internally rendering at 400x240 and physically displaying the pixels as rectangles at 800x240, you think Nintendo should patch the console and to make the 3DS internally render at 800x240 with non rectangular pixels while in 2D mode?
    Or are you suggesting that they retain the parallax effect but render the same image for both eyes?

    EDIT:
    I'm off to bed now, Nice chatting :)

    Ever played a Gameboy game on the 3DS? They doesn't support 3D but 3D mode can still be enabled. Pixels are looking normal in 3D mode (despite their is no 3D), but when you disable 3D mode, the pixels suddenly become blurry because of the same reason described above. Weird enough, NES games don't have this 3D mode, so they look as crappy as 3DS games with 2D mode. So what I'm basically suggesting is to enable this 3D-less 3D mode for all games.

    Wow I thought it was just me that noticed the Scanline effect. The resolution is so low compared to modern PPI standards - BUT the 2D mode shouldn't be this bad. I find it distracting. So I made this graphic tonight so I could a) see up close for my self but also share with the world what I and others see as a flaw:

    Thank you sir. This is exactly what I mean. I don't get why this is not mentioned in any 3DS review so far.
