Have you tried having it autoscan without trying to add your own custom mode lines? I don't have the same LCD but I do have two NEC MultiSync LDC1800 running in Xinerama mode off a nVidia GeForce FX 5200 runnning quite nicely at 1280x1024 without any flicker. All I set for the "Monitor" section was the HorizSync, VertRefresh and the DPMS option. I got the hsync and vsync from the NEC web site and it seems you have the appropriate values for your model. All mode lines are detected by XF4.3 on it's own. Regards, Jeremy T.
