Dell Homes support sucks. If you're forced to call back, choose Dell Business and get talking to an actual service rep. By the time they look up the monitors info and figure out that your not a business customer, they're so far deep into the process that they end up doing it for you anyway. I did that with my brother-in-laws laptop when I had to get a keyboard replaced.
Or if you know a Dell Tech, they can login and just order the parts for you. We're all certified at work and it's so much easier. Only problem is, they'll ship the part with the techs ID, so he/she is liable if the broken part doesn't get returned. So make sure if someone does a favor for you, that you return the part.
