I'm wondering if I can connect:
My conundrum arises because the iMac has only thunderbolt ports but LED Cinema Display uses a miniDisplayPort connector. The port shape is identical but I'm wondering if the connection works.
Here Apple says:
Thunderbolt and Thunderbolt 2 are not the same as Mini DisplayPort . They have the same shape, but use different symbols on the cable and port. However, this port does support Mini DisplayPort for video output, so you can use a Mini DisplayPort cable to connect a Mini DisplayPort display.
... but I'd like to doble check if somebody has already made this setup work.
