LCD "out of range" from Benq FP951

Hi, I just switched from Viewsonic G790 to Benq LCD FP951. It has been showing "out of range" when connecting to this LCD monitor. I changed a few settings in /etc/X11/XF86Config file, but it does not seem to work.

The video card is intel onboard video card, 82845G.
The linux is from RedHat 8.0.
The X server is attached at the end.

I am hoping any expert out there can give me a hint how to fix this problem.

Many thanks.

If the server is older than 6-12 months, or if your card is
newer than the above date, look for a newer version before
reporting problems.

What did you set the horzontal and vertical refresh rates at? According to this page it should be
Input Frequency Range:
Horizontal: 30 - 82 KHz
Vertical: 56 - 76 Hz

The frequency range had been adjusted in the XF86Config file, according to the manufacture's specification, and the problem was still there.

I had another computer with Radeo video card, and it worked with this LCD monitor. The one which did not work had Intel on board video card, 82845G.

Are you aware of any X11 issue with 82845G when linked to LCD monitor? (X11 installed is 4.2)
