Display Port Input Stopped Working

[BDavis13]

I have 3 HP Pavilion 27Q displays, all connected to my desktop via Display Port, display extended across all 3. The graphics card is an MSI GEFORCE  GTX1660 Super with 3 display port outputs and 1 HDMI output. This configuration has been in use for just under 2 years.

The display port input on one monitor has stopped working. I've connected it to all 3 outputs on the graphics card using 4 different display port cables (all outputs and cables verified to work on the other displays) and the monitor fails to display in each case. 

I finally connected that monitor to the HDMI output on the card and it works. So I'm back in business for now, but what if one of the other monitors suffers the same failure? There's only one HDMI output on the graphics card and it's now in use.

1) Does HP support their monitors at all? I can't find any information on repair centers for HP displays. 2) Am I missing anything? Is there a hardware or software reset or anything else that might restore full functionality?

Thanks
