I am struggling to find a solution to this - hopefully someone will be able to help.

Windows 10 recognises two displays - the external monitor and the laptop display. However, under Intel's control panel, it only shows the 'built-in display' in the drop down menu, which is the laptop's display. There should also be the external monitor. Lacking this, I am unable to adjust the gamma and brightness - I've already tried a couple of gamma utilities without success.

I've uninstalled and reinstalled fresh Intel drivers and also the displaylink adaptor which the monitor is plugged into via HDMI.

Would greatly appreciate a solution, even if it means some sort of registry fix.
