You should be able to run straight DVI from the monitor to the 9800gt card. I have a Samsung 220WM. The card detected the screen and automatically configured the screen resolution. If you can get you other screen to work I would suggest going to Nvidia for the current driver for the card. Set the program to all defaults for you card and monitor. Check to see if your screen can be changed to DVI input. I think mine had that offering and I selected DVI. Also, get the driver for you monitor at the Samsung website.

Edit: if I remember correctly, once I loaded the monitor driver from Samsung the video card did it's magic and set the best resolution for the screen.
