HP Z27 DisplayPort has stopped functioning

HP Recommended

I have been using two brand new Z27 monitors for a month now. This week, the DisplayPort in on one of the two monitors has stopped working. Other ports, including HDMI continue to work.


I have confirmed this is not a cable issue, dock issue, and that it is not a driver issue (the other monitor is working perfectly). 


I have factory reset the monitor, connected it directly to my computer instead of through a dock, and other things and nothing has worked. I will have to return this monitor if I can't resolve the issue.


Any other troubleshooting steps I can take?

I reviewed your post and I understand that the display port is not working on the computer.


Don’t worry, I assure you I will try my best to get this sorted.


I see that you have already performed all the relevant steps and I recommend you contact support and check the available service options for the monitor.


Here is how you can get in touch with support.


1)Click on this link –

2)Select the product type.

3)Enter the serial number of your device or select let HP detect your product option.

4)Select the country from the drop-down.

5)You should see the HP phone support number or Chat option listed.


Let me know how it goes and you have a great day!
