Windows 10: HP ENVY x360 laptop screen flickers and goes black after Win 11 update

Hello,My HP laptop x360 screen flickers and the screens goes black after the Win 11 update. The current Display driver is Intel Iris Plus Graphics Version 27.20.100.9316 . Ran Update Driver but there is no newer version to update. Also change refresh rate to 40hz but issue still persist. Any other suggestions?

HP Envy x360 with 1440p screen?

So I bought a refurb HP Envy x360 with the AMD FX 9800P and recently discovered I could set the screen resolution to 2560x1440 despite HP advertising this machine as only being capable of 1920x1080. Has anyone else bought one of these and found they could change the resolution to 1440P? I was thinking maybe since mine is a refurb that it was originally returned for some kind of screen issue and they replaced the screen with whatever they had lying around that day, which could well have been a screen meant for a Spectre, and not an Envy, since the Spectre does come with a 1440p screen. Would a mistake like this even be possible? It came in an Envy box and it says Envy everywhere on the laptop where it should say it. There is no external evidence that this might actually be a Spectre and not an Envy. So is this a fluke or all of these capable of displaying 1440p instead of being limited to 1080p as advertised?

 

HP x360 Black Screen

Since I have not found an answer to this problem, I thought I would ask here.... Just updated to Win 10 from 8.1. have an HP x360 11inch convertible laptop. NOW, when I shut down, when I go to turn on my computer, it get the HP logo, boot begins, screen
goes black. No cursor, can't login, nothing. I have to push the power button to put it to sleep and then power again and I get the login screen. I have turned off hybrid, fast boot, etc. Nothing has worked. I have uninstalled video drivers and reinstalled
MANY times to no avail. It is an Intel processor and Intel HD Graphics.

 

Brand new HP Envy x360....stuck in blue screen modw

I have a brand new HP Envy x360. In the middle of an update I got the " pc ran into problem" blue screen, it then goes to the black screen of " preparing automatic repair " where it sits. I've tried using the Windows key, F2 & F8 key, nothing changes.
I can't reboot, I can't get to any screens to try any recommendations I've read so far. HELP!
