After connecting the Cable ensure you are extending or projecting the display on the external monitor

I also suggest you download and run the HP Support Assistant from this Link: https://www8.hp.com/us/en/campaigns/hpsupportassistant/hpsupport.html?jumpid=va_r602_us/en/any/psg/p...
HPSA will automatically search for all the latest drivers for your Notebook

Also ensure Windows is up to date.
Select the Start button, and then go to Settings > Update & security > Windows Update , and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available
