Can MBP 16" ( Late 2019) retina screen can be replaced with non-retina non-Apple screen? I am getting some lines on one end of the screen I went to Aptronix (Apple retailer in India) customer care they are saying its pressure damage. I have never dropped the laptop nor hit the screen accidentally, but there some little scratches from normal usage. They mostly likely do not want to cover me under warranty so I am searching for alternate options. I wanted to replace my etina screen with a non-retina display like some UHD screen or any other screen.
No, that is not practically possible.
It is of course theoretically possible, but the costs involved for a one-off would be so high that you could buy a Retina display instead at lower cost.
