I have a Dell XPS 9550, equipped with a Thunderbolt 3/ USB-C port. I am trying to use my iMac 2011 as a target display.
I read that this can only be done using the Thunderbolt (V1 on iMac) port, and bought the Thunderbolt 3 to Thunderbolt 2/1 adapter from Apple. Using this configuration, I am not able to put my iMac in TDM.
I thought that as long as the whole protocol is kept Thunderbolt, I can do this. Any help? Or is this not compatible?
