We cannot derive anything from those Vostro CPU numbers. Every Dell PC has a private service tag number on the label. You would enter each the private service tag number here to see the specific model, warranty, etc.

Concerning the monitor serial numbers. See my instructions here =
Monitor model identification from the serial number

Hi Chris,

Thanks for your reply. It has been a few months and I am unable to track those units, which is why I need the details of the model. However thanks for the reply.

Concerning the monitors, I tried and still no luck. I will try once more with different key words.

Thank you so much. This is awesome. Truly grateful and highly appreciate your reply!
