I have a MacMini which is a couple of years old now, it has ONLY a DVI connector on the back, no display port.
I recently bought a Dell U271 monitor which is capable of going up to 2560x1440 using a Dual Link DVI cable under Linux. If I take the same cable and plug it into the Mac Mini, it only goes up to 1920x1080.
Can it go higher? Or does this question apply: https://discussions.apple.com/message/6672268#6672268 and it's only single dvi out?
Also, switching to a single DVI cable gives me the option of using 2048x1152, but no higher. thanks.
