Hi ,

I have a problem that seems to only affect linux systems attached to my
Gateway FPD2275W monitor ( meaning it isn't a problem for a Mac laptop
attached to the same monitor ).

All of my lines ( such as the side of a mouse or the edge of a window )
have a ghost line that is about 5 mm away . What this means is that I
get a headache after looking at the screen for too long. I actually try
to do most of my coding in a straight tty terminal ( ctrl-alt-f5 for
instance) just because the resolution is so much better.

Here's my configuration and what I've tried

- Graphics card is a GeForce 7050 PV / Nvidia
- System is Fedora core 9
- I'm using the tool "nvidia-settings" to configure some parts of my
monitor settings.
- My settings are
1600x1200 resolution
Freq = 60Hz
Input is VGA ( not DVI )

The following is my xorg.conf file

Thanks for any help or ideas anyone might have.

Could be caused by reflections in your cable. Maybe you don't see them
under MacOS because the dotclock it uses is higher or lower than the
cable's resonant frequency.

When I had that (on a CRT, 1536x1152 resolution) I fixed it by getting a
better (more shielding & more insulation -> stiffer & thicker) monitor
cable. You might also be able to fix it by hand-rolling your mode(line).
Or by using DVI if available (I'm not familiar with that card).
