Intel HD Graphics 5500 + Windows 8.1: Extend Display Not Working

[ELaza2]

My HP Pavilion laptop is barely 3 months old.

I was able to connect another Acer monitor to my laptop via HDMI port without any issue.

Last week, when I plugged the monitor again, the laptop cannot detect the extended display anymore.

I right-clicked the desktop and went to Intel HD Graphics but the option to extend/clone display is gone.

I re-installed the latest Intel graphic driver several times but to no avail.

I browsed countless forums already and downloaded several installers for graphics drivers but it is still not working.

Hope somebody can help.

It appears be an issue with the windows registry. Something changed the registry that is not detecting the external monitor.

You could try to uninstall any Intel(R) graphics driver from Control Panel and reinstall the latest version.

Also, you may try running system restore:

To restore your PC to an earlier point in time:

1. Swipe in from the right edge of the screen, and then tap Search.

2. Enter Control Panel in the search box, and tap or click Control Panel.

3. Enter Recovery in the Control Panel search box, and then tap or click Recovery.

4. Tap or click Open System Restore, and then follow the instructions.
