Vertical line display issue appeared, and I bought this less than a year ago. Tried troubleshooting online, and even some tips on this community on other monitor by pushing the monitor's edge and nothing helped.
I tried to reach out to HP supports and it has been a terrible experience. Waited for almost an hour by calling 1-800-474-6836, the rep said she cannot helped with my problem, and transferred my call somewhere else. I asked for the other department phone number so I don't have to go through her again - None given. I got through to the other department, and the guy acted like my warranty is out of date. I offered to showed him proof that I got from HP product warranty page (still said I have about 20+ days) by sending it to his email. He said yes then hang up.
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!
