dell xps - mini displayport to VGA not working


Very simple problem: I am trying to hook up a laptop to a projector via a Mini DisplayPort to VGA connector, however it just doesn't work at all.


Where this gets odd is:



  • This all works to the second monitor on my desk - thus the Mini DisplayPort, OS/Drivers & adapter are working.

  • This all works if I take the VGA cable from the monitor and plug in the projector directly this would imply a cable issue to the projector.

  • Other laptops work with the normal monitor VGA cable albeit without the adapter, seems to eliminate a catastrophic the cable issue.

  • There are no pins missing from the projector cable.

  • The projector is pushing out the plug & play info.

  • Tried on a second projector with similar config and same issue occurs.


This leads me to think an issue exists between the combination of the adapter & cable. The only key difference I can see between the screen cable & the projectors cable is length (projector cable is much longer) but still within the 15m.


The question I have is how to get this working?
If you have next steps in troubleshooting, I would love to hear those too.




Laptop is a Dell XPS 17
Adapter is an Apple Mini DisplayPort to VGA adapter
Second screen is a Samsung SyncMaster 732N
Projector is an Epson EMP-83
Second projector is an Epson EH-TW6000
OS is Windows 8


Update


Tried with a hama Mini Display Port to VGA adapter and same issues


Answer



After trying every HDMI adapter I could & found the failure rate at best 40%, I settled on a USB 2.0 Display Adapter (it has outputs for VGA, HDMI & DVI). It has always worked so seems like a safe choice.
