KB5077181 update causes HDMI port to fail

KB5077181 update causes HDMI port to fail. Worked prior to this 2/11/2026 update.

K have the 3 display devices: Dell 1536 Laptop Integrated Display, dual monitor duplicated on HP2301 Monitor on USB-C port. Prior to the update, the HP2311 Monitor on HDMI port worked as well. After the update, the 2311 monitor does not see an HDMI signal and goes to sleep.

I also tried the handshake reset procedure (obscure procedure found with CoPilot) which fixed a similar issue with 25H2 update, but that failed. 

No configuration or driver changes. Note - monitor drivers are no longer supplied for W10 or later OS. The 2311 shows up when I selected "Show Hidden Devices".

Hesitant to try AMD graphics update, BIOS, etc., as the 2301 monitor is also still working. Last, tried to do a uninstall of this KB, but apparently not possible with this update.

Suggestions? Thanks.
