Q: Target Display Help

I have a mid 2011 21.5" imac that I want to use as the display for my late 2015 27" 5k retina imac. Both have el capitan. I connected with thunderbolt cable, pressed command + F2 at login screen on the 2011 imac and nothing happens. I have tried with 2 different brand new apple thunderbolt cables.

 

From here - Use your iMac as a display with Target Display Mode - Apple Support - I gathered that imac with retina can't be used as target display mode display. Am I interpreting this wrong and it's not even possible to use my 2011 as the display, because my 2015 has retina? If so, are there alternatives? Basically what I want to be able to do is drag stuff between screens while I'm working. I'm not tech savvy so any advice is appreciated, thanks! ^^

iMac with Retina 5K display, OS X El Capitan (10.11.3)

    Yes, you should be able to use your mid-2011 iMac as a display for your new iMac.

     

    Have you tried the items suggested in that article:

    • In Keyboard System Preferences, if the checkbox is enabled for Use all F1, F2, etc. keys as standard functions keys, the key combination changes to Command-Fn-F2.
    • Make sure your Mini DisplayPort or Thunderbolt cable is connected to both computers.
    • If you're currently logged in on the iMac you want to use as a display, try logging out to return to the login window. Then press Command-F2 again.
    • Some older Apple keyboards and third-party keyboards might not allow Command-F2 to toggle display modes. If this happens, use the keyboard that came with your iMac to toggle Target Display Mode on and off.

    Good news! This is really dumb of me but I tried taking out and plugging in the cables again and apparently I had the cable plugged into my 2011 port upsidedown? I flipped it around and now it works. Yay!
