[SOLVED] no monitor

I have recently got a second user 17"svga monitor. After connecting to my pc there is picture during bios phase but as soon as win 98 should start the monitor indicator goes from green to orange!(standby?)
The monitor is ok on another pc running win 95.
My machine is p111 650 with sparkle nvidia graphics accelerator.
My 15" svga works fine.
Any ideas

Thanks to whoever for thinking of me as a junior guess i filled the registration form wrong.

 

Couple things

You may want to check the manufacturers site for windows drivers for the monitor.

Other thing would be to remove your current monitor in device manager, then shutdown, change the monitors out, reboot, and hopefully windows will recognize the new one and install the correct drivers

 

After re setting page size to 640x480 and removing graphics driver. On restart plug and play re installed driver and all was fine.
I had also got latest driver from manufacturers web site. Howard
