Digital BW, The Print

The history: When used with a single-monitor Dell-generic card, the 
Artisan GDM-C520 installed and calibrated as expected. Like many I 
bought a dual-VGA card so I could use CS2 on 2 screens. The first 
was the Matrox 440. No problems installing and setting up dual mode 
with XP. Then went through purgatory trying to calibrate. The 520 
was the primary monitor and the equence went like this: Cal. starts 
and before the power resets I get "An error occurred while setting 
the gamma ramp on the graphics card...." Sometimes I could just 
restart the exe or cold boot and gett past that error. Then after 6-
7 minutes (6 slices on the time pie) while working with black and 
grey, up pops "An error occurred during calibration. Please allow 
the display to warm up completely. The room should be dim..."  The 
room was very dark and the monitor on for several hours. Cannot 
switch 520 to #2 monitor because the cal. program only runs on mon. 
#1. Uninstalled 520, Artisan software, and all the sensor drivers; 
reinstalled but still no joy. After a lot of Googling and had a few 
hits with same problem but inconclusive or no advice. I posted on 
digitalblackandwhitetheprint on Yahoo and was told the Matrox is 
junk and go with an inexpensive nVidia. I bought and installed a PNY 
verto geForce 5200 with 256mb. All went well, but the cal. throws 
the same errors exactly the same even after completely reinstalling. 
Tried using 520 as only monitor, but same errors. My wife has put me 
on suicide watch. I just want to get on with my photography life and 
learning. TIA for any Help and/or Insight!
