Booting up Overwatch stuck on blank screen?

Solution 1:

I've had this problem for ~6 months now, PTR and Live.

I have a Windows 10 box, and what I do when I encounter this is

  1. Create a new Desktop (using Windows+D)
  2. Open up Task Manager in the new desktop
  3. End the Overwatch and Battle.net Launcher processes
  4. Open the Launcher and try again

I've had to repeat this process 6-7 times sometimes before it works, but it always eventually works.
