21.5 inch iMac Late 2012 use as External Display
I have a Macbook Pro Mid 2012 that I'm trying to connect to my 21.5 inch iMac Late 2012 as an external display. I did some research and saw that I could use a HDMI to DisplayPort as a connector, but it does not work. Tried target display mode as well with it.
Im thinking I need thunderbolt to thunderbolt? Or would DisplayPort to DisplayPort work? Please let me know! Thanks.
