Hi,

Recently reformatted my computer, and installed the updated bios from HP, and now my computer won't support dual monitors. I've been all over the net looking for a solution and all I can confirm is that everyone else who's updated their bios is now having the same problem.

I've been told that contacting HP does nothing. Any help would be appreciated.

Quick, practical triage (keeps you from flashing anything risky)

  • Reproduce the problem outside your installed Windows: reboot and watch for any output on the external monitor during POST/BIOS splash, or boot from a Linux live-USB/Windows install media. If the external shows an image before Windows loads, the hardware and basic BIOS output path still exist; if it never shows anything, the BIOS update likely changed the chipset/port configuration.
  • Try the display-toggle hotkey (Fn + the monitor key) and a different cable/port to rule out a simple detection/cable issue.

Driver-focused steps (builds on )

  • Do a clean driver removal in Safe Mode (use a driver-clean tool such as DDU) and then install the latest graphics driver from the GPU vendor (Intel/AMD/NVIDIA) rather than the OEM package. After install, check Device Manager -> Display adapters and Windows Display Settings -> Multiple displays -> Detect.

BIOS and recovery notes

  • Look in the BIOS for any “Display”, “Graphics”, “Boot Display” or “Switchable Graphics” options; a setting may have been reset. If an older BIOS is required, search HP’s support by exact product/model number or request the older “SoftPaq” from HP Support — some vendors will provide a rollback image by request. Downgrading a BIOS can be blocked or risky; make a full system image and a BIOS recovery plan before attempting.

If nothing else helps

  • As a temporary workaround use a USB-to-video adapter or docking solution. When contacting HP, give them the exact model and current BIOS version and mention this thread and other reports to push for a supported rollback or fix.
