[Fixed] UE5 editor black screen

Development Getting Started & Setup
, ,
1

I’ve just installed UE 5.4, opened a blank project and when I maximize the window my monitor goes black, and turns off after a timeout
I’ve found there’s a few editor menus that cause it too.

My PC:
12th Gen Intel(R) Core™ i7-12700H 2.30 GHz
64.0 GB RAM
Win 11 64bit 23H2
GeForce RTX 3080 Ti Laptop 48GB RAM

I have tried the following fixes:

  • Latest NVIDIA Game ready drivers
  • ProjectSettings > Platform Windows > DX11, Vulkan
  • Nvidia MFAA turned off globally
  • UnrealEngine.exe disable fullscreen optimizations
  • UE5.4, 5.3
  • Latest NVIDIA Studio Drivers

EDIT: It’s not happening now. Not sure what fixed it :frowning:
I downloaded 5.2, and the latest UE4. UE4 worked, then I went to 5.2, which worked, then 5.4 which is working now.
Oh well, at least it’s working I guess.

Hey there @somenzguy! Welcome back to the community! This is likely related to an error reported to have been fixed in 5.4:
