I’ve seen mixed responses on here already about this question so wanted to see if there was any further confirmation. As you’ll see In the screenshot I attached someone mentioned it’s possible if you make sure to switch the cables from each display to the new screen. Does anyone else have experience of this? Main reason for not buying the 2017 replacement screen is that it cost £300+ whereas the 2015 Retina one I’m looking at is £135. I see no reason to spend more if it’s gonna work. Thanks!
The question is more of which way things might work! If you read the rest of the dialog Fitting 2015 4K screen into a 2017 4K system? You’ll see there is a difference in the ribbon cable connections!

There is a big difference between the interfaces! eDP on the 2015 model and iDP on the 2017 4K displays. Kaellis who jumped into the dialog I think was confused! What I’m suspecting happened is he got confused between the Retina Vs 4K displays as both the ‘15 & ‘17 series offered a Retina model which as it turns out use the same display (older eDP)! So if you have a 4K display you need to replace it with the correct one!
