Sorry, sorry sorry,
I forgot to write the question!! The problem is that when I connect the Projector to the DVI output of the Radeon 9000 or Radeon 7000 I only see noise!!! With my old G3 connected to the Radeon 7000 I see a perfect picture!!!
Have i done something wrong???
Probably the two cards are incompatibe??
Another strange thing ist that if I turn on the Video duplication, the sreen refresh is slower. Also watching moovies over Quicktime, or Vlan is slower???
Thank you again, and SORY for not finishing the question!!
