hi there
i know..this is about nvidia but still..
has any1 tried xpand 3d glasses with samsung 2233rz monitor? does it work?

thanks in advance,

Unfortunately not. We have tested this and asked XPAND Europe directly because it did not work.

The answer was, that "the monitor will currently work only with the Nvidia glasses" (currently means November 2009). Very annoying. I didn't have time then to find out the technical reason for this.

Maybe someone here knows more technical details.

There are two reasons why it won't work :
-The Xpand shutter glasses require to use the Xpand emitter.
-Even if you do have an Xpand emitter, the Xpand emitter only connects to a Vesa 3D sync port directly driven by the display, which the Samsung 2233rz monitor does not have.

Keep in mind that all the currently available 120Hz desktop LCD monitors are not 3D monitors, they are just 120Hz 2D LCD monitors : they don't know what a left or right eye image is, all the 3D mode is performed remotely by the graphics card.

This is all correct.

Thank you for your feedback.

We did use the XPAND emitter connected to the Vesa MiniDin stereo port of a Nvidia Quadro card.

I think the port is driven directly by the graphics card and not by the monitor (display). As you state, only the card knows which view is currently displayed and can therefore trigger the shutter glasses. Otherwise using old CRT displays would not work, because these certainly do not "drive" the Vesa 3D port.

So it seems to me that the point is not completely clear. My guess is, that either it is simply the electrical signal at the stereo port which is different. Or maybe the LCD displays do not work with the usual on-off glasses at all and use some kind of polarisation effect?

Does nvidia still support Quadro/vesa port ?
I thought the new drivers only worked with nvidia approved glasses (the only ones are the nvidia glasses) ?

Hi BlackSharkfr,

we bought a PNY Quadro FX3700 because this card still has a VESA/MiniDin stereo port which we wanted to use for our Xpand glasses. We have about 30 of them so I am very frustrated that Nvidia now only supports her own glasses.

Any ideas yet about the difference between NVidia and other glasses?
