I was using two monitors with two ATI Radeon 4800 cards and that worked fine. I just purchased another monitor (Samsung) and now I cannot get it detected. The device manager is only showing 2 generic PnP monitors. I'm not sure why they would not be the specific monitors brands either (one Samsung and one Acer).
Any way of getting the third monitor detected? I've heard about deleting the graphics card drivers and then the monitor might be deteced. But I do not know the procedure for doing that.
