Hi,
  We will need more information to be able to help you out.
In general, you have two major approaches for using passive
stereo on a TV. One way is to depend on the GPU and its graphics
driver to supply quad-buffered stereo, and drive the TV using
an HDMI stereo 3-D signal and video mode. In that mode, you would
tell VMD to use quad-buffered stereo in the Display | Stereo menu,
and you might need to set the TV mode to enable 3-D display.

The other way of getting stereo is to run the TV in a normal
(non-stereo) display mode, and leave the GPU driver set with
quad-buffered stereo off/disabled. In that mode, VMD would
generate the stereo signal itself using row-interleaved
OpenGL rasterization in software, and you will need to ensure
the correct left/right eye mapping by turning on/off the stereo
eye swap feature in the Display | Stereo menu if you move
the OpenGL window around on the screen.

If you can tell us more specifically exactly what steps you've
taken we can give further guidance.

Cheers,
  John Stone

We have used the stereo>rows option and while we do get a 3d image the protein appears as horizontal stacks that push out of the screen instead of a spheroid shape which we should be getting. We also tried every of the other options in the stereo menu, but neither one of them is giving us the right shape in terms of depth
