Topic: No definite "sweet spot"

Maybe I'll try that...I've been noticing this ghosting/crosstalk thing in Super Monkey Ball every now and then too.

I've noticed this now. It's not actually "crosstalk" (as I understand it), but rather a result of not being completely within the "sweet spot." I posted a topic about difficulties of getting entirely within the "sweet spot" here. You have to make sure it's the right distance from your face as well as holding it at the right angle.

@WaveBoy The other problem with Plasma is the HUGE power consumption compared to LCD and especially LED backlit LCD screens. Not that good for a portable gaming device. Anyways, the reason those active glasses 3D TVs tend to be better with Plasma screens is because of the way it works. The screen quickly swaps between two images over the whole screen and the shutter glasses close off one eye or the other when the image displayed which is why LCD does worse.... because LCD tends to have more motion blur than plasma.

The 3DS doesn't use that technology so there would be no difference between the 3D effect an LCD and Plasma or OLED screen on the 3DS. The problem of the OP, as people have said, is most likely to do with not being able to find the sweet spot but if it is light "bleeding" across the parallax barrier turning the brightness down SHOULD reduce the crosstalk

Actually, while what I posted above is true, I did notice some of this "duplicating" effect while looking at the head in the Mii Maker that I couldn't get rid of no matter how I held the 3DS. I didn't notice any of this while playing SFIV except when the image was slightly out of focus from the way I was holding it. It may be connected to high-contrast situations, but it definitely does look like there's some of this crosstalk going on. One more minor disappointment about the 3DS I guess...
