https://www.cnet.com/news/microsoft-blinks-will-replace-flickering-surface-pro-4/ >Owners of the Microsoft Surface Pro 4 detachable have been complaining for almost as long as the hybrid has been around of screen flickering that renders the display unusable -- frequently just after the warranty has expired. It's so rampant it has a name -- Flickergate -- and a discussion board.  >Microsoft finally gave in and admitted that its attempts to fix the problem with firmware and driver updates have failed, creating a program to replace faulty Surface Pro 4s less than 3 years old with refurbished models. (Since the device shipped in 2015, at this time they're all under 3.) It also says it will refund people who've paid for out-of-warranty service already.
