KB5077181 update causes HDMI port to fail
Paul2: I was able to remove the KB, have paused updates for one week. In spite of that, Windows update attempted to reinstall it but failed. Also tried a different HDMI monitor - no signal. Still open to suggestions.
Problem solved. Embarrassed to admit a cable labeling issue 😒. The HDMI port and 2311 monitor was working, but the USB-C port / 2301 monitor was not. My issue was resolved using a DELL-provided hard reset.
This was a two external monitor and laptop integrated display setup.

To perform a hard reset on a Dell computer, follow these steps:
- Turn off the computer.
- Disconnect the power cable (for desktops) or disconnect the AC adapter and remove the battery (for Dell laptops with removable battery).
- Disconnect all devices such as USB drives, printers, webcams, and media cards (SD/xD).
- Press and hold the power button for 15 to 20 seconds to drain the residual power.
- Connect the power cable (for desktops) or AC adapter and battery (for laptops).
- Turn on the computer.
Step 4 seems to have critical as I did many of the steps previously.
