Hello, I have a Dell Leptop with an Nvidia Quadro M4000M (GTX 970). All drivers from type 466.77 no longer work. All older drivers will also work, only newer ones will no longer work. All newer drivers produce a black screen after installation. The laptop works, but after the uefi logo "DELL" I have a black screen. I've tried all the newer drivers, including the 496.13. Can someone help me analyze the problem? Is that a bug in the driver from version 466.77?
