HI All I was wondering if anyone here has tried to run two dvi monitors off the single dvi output of the Matrox g550mdha32lx card? According to matrox website u need their model number g550mdda32lx to do this. But, It seems to me the software of the mdha should be able to run the dual head feature anyway. I talked to someone from out of state and he said he does run two dvi monitors off the mdha card. But, when I contacted the matrox service, they said not possible. Of course, they charge alot more for this card, and doubt they would admit such a thing. Have any of you guys tried this? sterling
