I got the same trouble and got it fixed:
Contact Zalman e.g. at [log in to unmask]
I got this answer:
Dear Joachim,
I apologize for the delay in responding to your inquiry. I was away on
multiple business trips abroad, and was terribly occupied.
I can provide the fix – a custom DVI cable specifically for the
ZM-M220W. It resolves the issue of the swapped pins 15 &16 of the
ZM-M220W, which is not an issue with older graphic cards/GPUs(I infact
use the DVI connection with my office PC that has an Nvidia GeForce 7600
card), but is an issue with newer / notebook GPUs.
Basically, newer GPUs seem to have acquired a function that actively
sends and receives a signal to and from the monitor to check if a
connection is made, and if it does not get a return signal that it is
looking for, the GPU’s output shuts down. With the ZM-M220W’s swapped
pins 15 & 16, the newer GPUs don’t get the return signal and thinks that
no monitor is connected and shuts the output off. On older GPUs, this
function is not common and so the GPU outputs constantly without
regarding for the pins 15 & 16.
Okay, so please fill out the following FedEx Air Waybill template and
send it to me, and I will have this custom DVI cable sent to you.

We can't get the MACS to even _recognise_ the existence of the Zalman display using a minidisplay port ->DVI adapter and also using Thunderbolt out on a new iMAC (minidisplay port) --> DVI adapter. This is a real problem if one wants to do stereo on MACS...
