Today I connect my MacBook Pro 15" 2018 to an iMac 27" 2011 through thunderbolt with an adapter (thunderbolt 3 to 2) to use the iMac as a display. Will my iMac be able to go into Target Display Mode if I put a Blackmagic eGPU between the MacBook and the iMac?
Yup, the eGPU sure won't help the iMac, but as long as the iMac is just a screen, the thunderbolt 2 should be sufficient.
Here is the reply from Blackmagic:
You can use target display mode through an eGPU if you wish to do so.
You would, as you have noted, need a Thunderbolt 3 to Thunderbolt 2 adapter to connect the iMac to the eGPU.
Looks like this will work then.
Unlikely since Target Display Mode is meant to connect two Macs. You can alway ask Blackmagic support.
Thats what I am thinking. I sent the question to Blackmagic, thanks for the tip.
You're welcome. The other issue is eGPUs require Thunderbolt 3 speeds which your 2011 iMac doesn't support.
So it seems if they are correct.
MacBook Pro 2018 and Blackmagic eGPU with iMac 2011 as display possible?
