Did anyone find a fix for the original post?
My dell monitor 2415 came with a mini display cable and worked out of the box, the only problems being constantly having to change font size for some programs. After about 3 months I switched the xps on and it cannot detect the monitor so the monitor goes into sleep mode.
dell display manager does not load as it cant see the monitor.
NVidia control manager only seems to offer 3d settings
intel display does not see the monitor
