[Newbie]trident driver problem

[Arun]

I have a problem with starting X windows system.   my comp config is   P II 350 MHz 96 MB SDRAM 20 GB HDD (4GB to LINUX) Trident 4MB AGP Display card LG studioworks 563N 15'' Monitor   monitor specs - H. Freq - 30-61 kHz                           V. Freq - 50-120 Hz   my computer can do 1024x768@32bit color in Windows 98.   I am not able to make these settings in linux 7.0   I tried Xconfigurator but no combination works  out.   The system correctly detects both the monitor and the AGP card but when i let it test setting, the system hangs. The monitor displays "Out of Frequency range" error. when i have specified the range of frequency why would the system produce out of frequency signal?? if anyone can help out please mail me thanking you arun
