Gaming Notebooks

The latest Windows 10 update is causing resolution issues (Alternating1/4 Display  and Blinking Black Screen) with the login window and even after login.

My OMEN17 notebook defaults in a 3840 by 2160 display resolution and I have to change it to 1920 by 1080 for certain software that do not support that resolution. In the past I could keep it at 1920 by 1080 and login with no issues after shutting down or restarting.

With the latest updates however, if I set the display settings to 1920 by 1080 and shutdown or restart the notebook, the login screen will appear to be either completely black or displaying the full login window within 1/4 of the notebook screen while leaving the rest black. These two displays will then alternate every few seconds, during which I am unable to see the cursor although I can type in my password and login. Even if I am able to login however, the screen continues to alternate between the black screen and the 1/4 sized desktop window and I am unable to see the cursor to change the display settings back to 3840 by 2160. The only workaround currently is to start in low resolution mode and change the resolution back before restarting again.

I only found out what was causing the problem after multiple resets; I initially thought the update corrupted the graphics driver so after calling up HP support I was instructed to reset the computer and reinstall windows. This has however, not fixed the issue even though  I block windows from updating itself. 

Any support will be much appreciated, thank you.
