To expound, notice the details on the 2010 Mac mini models with the NVIDIA 320M. http://www.everymac.com/systems/apple/ma...specs.html
"*This model simultaneously supports 1920x1200 on an HDMI display or a DVI display using the included HDMI-to-DVI adapter and 2560x1600 on a Mini DisplayPort display or a VGA display (with an optional Mini DisplayPort-to-VGA adapter)."
The text is completely different now, even though the late 2009 model (which is using the same chipset as the OP's early 2009 model) and the 2010 model both shipped with Snow Leopard. So it can't be a discrepancy based on initially shipped operating system, right?
This is weird, but I would guess if the OP says it isn't working with mDP to DP, which is what Apple and EveryMac both report as well, then it must be a chipset/driver issue/limitation with the 9400M versus the 320M (and newer GPU options found on newer Macs). Otherwise, I'm at a loss to explain the problem. Bad display?
