Please help with connecting external display to an imac 2013 OS X 10.8.5.
I have connected an external monitor (Fujitsu Siemens) to the thunderbolt port of the imac using a Mini DisplayPort to VGA adapter. The imac does not detect the external monitor. I have followed all instructions and suggestions I could find at discussions.apple.com without success. The monitor is in perfectly good working order as it has no problem connecting and performing correctly with a dell windows pc.
Any advice and help will be appreciated.

First unplug adapter/cable and plug them back in - always first thing.
The monitor does not have any other connection type? If it has DVI wouldn't even be trying VGA.
Next question would be, what adapter did you buy - link to your specific adapter would be good.
The adapter itself would be my first guess after troubleshooting.
For troubleshooting step by step, head to the following thread - post # 2.

Thank you bobtomay for a quick response.
Did the unplug/plug - no change, unfortunately. The monitor has only a VGA connector - legacy from previous use, as it was the simplest 'no thrills' solution to 'extending' pc display. It has always worked in that job flawlessly.
Amended part of post:
Previously, wrote here that I was unsure how to check the adapter. It's now been checked - imac connected via the Mini DisplayPort to VGA adapter to the D-Sub connector of a Samsung smart TV. Connection worked perfectly. For completeness here is also the link to the adapter details from the source of purchase:
It now looks like there is an issue between the imac and the monitor, as all components work in alternative connections, but not together.
