When I tried to replace the Sony Trinitron CRT with Dell

not work at all, the screen was blank.
The card should support the native resolution of
1280x1024 that Dell UltraSharp 1908FP runs on, so what's
the problem?
The problem is probably that the refresh rate is too high.
CRT screens typically run 1280x1024 at 75, 85 or maybe
even 100 Hz. A TFT monitor is usually limited to 1280x1024
at 60 Hz.
At most times the monitor is able to tell the graphicscard
which resolution and refresh rates it can use with
the EDID signals in the VGA cable. However, if this
doesn't work you might have to manually edit the monitor
section of your xorg.conf to enter the right vertical and
horizontal refresh rates.
Just like to add that sometimes putting in a Live-CD and
then start a linux-os might help. If the Monitor works one
can either copy the /etc/X11/xorg.conf file to HDD or copy
it down to paper.
The OP didn't say which OS he is using, so renaming
xorg.conf and generating a new file using the tools the
OS supplies could be another option. I'm using Ubuntu
Studio 8.04.1 and when I run a kernel-update, every time
the nvidia-card is misbehaving, so removing xorg.conf and
installing the driver helps here.
