Real 3D glasses doesn't work on my laptop?

These 3D glasses work through polarised light rather than by different colours. Without getting too deeply into the physics of how it works, a red/cyan or other set of different coloured lenses block out the other colour (blue won't go through the red lens and vice versa) so you see a slightly different image through each eye. Those different image combine in your brain and are interpreted as depth, giving the illusion of 3D to a flat image.

Those glasses you have do a similar thing, blocking out images so each eye gets a slightly different one, but instead of blocking out colours it's blocking out an entire spectrum of light at a different polarity: one eye sees an image with light waves going up and down, like this VVVVVVV, whereas the other eye sees light waves that go horizontally:

SSSSS

SSSSS

SSSSS

SSSSS

It's really hard to draw in text. But what it means is that you need a special screen, or projector to get the light waves going right. Your laptop screen probably isn't one of them, so those 3D glasses won't work with them. All is not lost - at least those things will work at the cinema, which uses polarised light for its 3D films.

To get 3D working on your laptop, you will need what is known as anaglyphic glasses, which have one red and one cyan lens. That's what I have when I want to run a game in 3D, with the graphics card pumping out the required red and cyan images. There's sadly no physical way (short of popping out the lenses and putting in some of the right coloured ones) of making 3D work with those glasses on your laptop. Sorry. :(

3d Glasses Not Working

Oh! Well, if you are using YouTube to watch 3-D movies, it is because YouTube does not do the RealD 3-D glasses, but they do the classic red and blue glasses. That is why.

if i buy n-vidia desktop thn ??
