Hi all, I'm having similar troubles getting hardware stereo working on my PowerMac Quad ppc with nVIDIA Quadro FX 4500 with a Philips 202P73 monitor and a NuVision 60GX emitter (salvaged from our SGI). I'm wondering if this is a power problem like Bil Clemens was having with his Stereographics E-2 emitter. Does the NuVision emitter need to have it's own power supply or should I just be able to plug it in and have it work? Has anyone been able to successfully use the NuVision emitter on a powermac with an nVIDIA Quadro without using a special power adapter?
Thanks for the help Chris

Just to let everyone know, the answer which got hardware stereo working on our Intel Mac Pro Quad Xeon (2.66 GHz) machine with an nVIDIA Quadro FX 4500 graphics board was the one from Tassos. The setup that worked with the standard NuVision 60GX emitter was a Sony CPD-G520P as monitor 1 and an Apple Cinema Display as monitor 2. In this configuration, MacPyMOL 0.99rc6 universal build, launched as a Mac app, readily went into quad-buffered stereo. O is now being set up, but Coot doesn't work (for other reasons, as mentioned in another thread).
While David Gohara's suggestion that the monitor numbering should not matter, but it apparently does. No other configuration worked. While I was intrigued with Bil Clemens' suggestion, I have not tried it. However, NuVision says that they only have an external power supply for their system for a non-stereo ready PC, and it does not have a 3-pin adapter. They instead recommended the same solution as Tassos did.
Again, thanks to all for their help,
Michael

I would not be shocked if NVidia propagated this feature in subsequent models including the cards in the Mac Pro series. A. On Sep 18, 2006, at 16:45, David Gohara wrote: 1. For the quad G5s, is it plug and play for the most part? In their case, did the CRT have to be monitor 1 or 2?
The monitor numbering shouldn't matter as the stereo visual follows the window not the monitor. So you should be fine there.
On my G5 with the 4500 stereo works fine in pymol and O. The CRT is the second monitor. The biggest problem was with the emitter. It turns out that the emitter connectors vary quite a lot in what they are supposed to do. The 'old' emitter I have is a Stereographics E-2 and it didn't work by simply plugging it in. The problem is that the 4500 connection doesn't send power to the emitter so you need an adapter that allows you to plug the emitter into an outlet. It is easy to get and fairly cheap. Once I plugged everything in stereo worked right away. I should add that it didn't work without the emitter. The company that I got the converter from ships a box with a lot of different connectors so there should be one for the NuVision.
