Hello,

We have received our LG D2342P-PN monitor yesterday and did a little test.
Simply put, it works perfectly for stereo display on COOT and Chimera. We
didn't test pymol, as the 0.99 version doesn't have support for the Zalman
mode. But the educational version of the new pymol seems to have the Zalman
mode.

Here I list some observations:
1. We had a Zalman ZM-M215W monitor shortly before this one. The two models
are quite comparable to each other.
2. Both the Zalman and the LG D2342P emit circular polarized light. So
simple linear polarization films won't be able to separate the light from
the odd and even lines. But the 3D stereo cinemas are of the same type. My
3D stereo glasses from a cinema is about 45 degrees counter-clockwise off
the LG glasses' axes, but the left and right images are not switched. So it
can work OK with the LG monitors, with only a little ghost image, and if I
tilt my head to the left then it is as clean as the LG glasses. On the other
hand, except for the two pairs of glasses came with the monitor, I haven't
figured out where to buy extra glasses yet.
3. Both Zalman and LG D2342P have wide horizontal viewing angles, but
limited vertical viewing angle (maybe 20-40 degrees) for the stereo display
(2D display is not limited). This is probably due to that there is a
distance between the polarizer layer and the pixel layer so that if viewed
from an angle above or below, some light from one row of pixels would have
to travel through the line of polarizer one row above or below and then the
polarization is mixed - just my guess.
4. Both Zalman and LG D2342P can work on any computer with a VGA or DVI
output and have nothing to do with the operating systems. No special driver
is needed. We tested them on our desktops and laptops, in Linux, real and VM
Windows. They worked just fine in all cases.

Regards,

Zhijie

Dear Zhijie:

I saw this for under $300 at Amazon's Showroom and wondered the same

thing.  I can verify that the LG TV will work with coot, etc., as long as

you turn OFF all stereographic processing and allow the software to do the

work.  There is an extremely detailed review of this at

http://www.amazon.com/LG-D2342P-PN-23-Inch-Widescreen-Passive/dp/B004WK3R4U/ref=cm_cr-mr-title

by Bill Costa (he gives his email address at the end).  He seems to

suggest that the 3D glasses for the LG TV are not compatible with this,

which left me scratching my head.

Having said that, I'll bet it will work fine.  If you can get it from Best

Buy for under $300 and return it within 30 days for a full refund, it

might be worth it.

Either way, let us know.

Dear CCP4BBers:

Sorry to bring up this highly repeated topic again. After some internet

research, we are about to make the commitment to buy an LG D2342P-PN for

setting up a stereo system. I would like to have a final confirmation

from someone with real life experience that this model does work with

COOT and Chimera the same way as the Zalman monitors. Thanks in advance.
