Using mini-display port with 2009 MacPro

So I'm trying to hook up my 2009 MacPro to my Acer CB280HK. It works fine if I go DVI out to DVI into the monitor. If I try using a DVI to VGA adapter output from the Mac and then a VGA to mini-display port adapter input to the Acer it doesn't. (This method worked with other non-UHD monitors) I'm guessing I have the wrong cabling/adapters. Before I buy any new cables or adapters, what is the correct method for hooking up a 2009 Mac Pro using something other than a direct DVI input?
