5K display assembly replacement
What is the display assembly part number?
Can it be replaced with older (2014/2015) models displays?
Model A1419 / EMC 3070 / Mid 2017 / 3.4, 3.5 or 3.8 GHz Core i5 or 4.2 GHz Core i7 Kaby Lake Processor (ID iMac18,3) / Retina 5K display. Refer to the older iMac Intel 27" Retina 5K Display (Late 2014 & 2015) guides as the system is very similar.
It would be risky to try until a parts listing is released.
Here is the Apple P/N 661-07323 - Mid 2017 iMac 27" Retina 5K LCD Panel & Front Glass Assembly
This is definitely something I would be interested in finding out as well. The display for the 2017 model is listed as an LM270QQ1-SDC1 and the 2014-2015 Model is listed as an LM270QQ1-SDB1. Spec wise they are the same but will they work for both models?
