Can anyone help me find the correct adapter for this... I have a 2012 Mac Mini. The Thunderbolt Port currently goes into my 27" Thunderbolt Display. I just bought a (used) 24" Apple LED. This has a Mini Display Port. Since I don't think I can daisy chain the 27 to 24...is there a way to get the 24" second display to work using the HDMI slot of the Mac Mini? I can't seem to find the correct adapter.
