      A screenshot to illustrate the issue is a huge plus. A video of the failure is even better! Attach to the post or provide the YouTube link.

      1. Install driver
      2. Enable power options to turn off display after inactivity and set to 1 minute
      3. Do not touch PC for one minute until display turns off
      4. Move mouse or press key to resume pc, but display does not come back.
      5. Using some guesswork, was able to select Logoff and screen reappears if you can get it to the logon screen.
      6. Test same steps at logon screen and display will resume without issue.
      7. Revert back to driver 10.18.15.4279 to resolve issue.
