I have now disconnect the flat and fragile cable inside the upper part
of the Inspiron 2650(sorry i do not know its name) thinkng it could be
a bit loose, i then replug it tighter. The connection to the monitor is
now firmly established even without the KVM switch. But not to the
projectors with or without the switch, at least the upper part of the
image is flickering and more if I move a little bit the VGA connector
inside its plug in the laptop. It can become completely bumpy on the
whole area. Does someone out there know the cause of such problem? Can
it be related to the electrical ground or bad shield? But why is a
projector different then a monitor?
Thanks,
Christophe
