恩 Reseller Monitor warranty policy Contact the reseller and get his original Dell order number for the monitor. That order number will tell us the start and end date of the warranty. If he cannot provide a Dell order number, he most likely did not buy the warranty coverage and bought them from us in as is condition. All the monitor PPID serial number does is show us the manufacturer date. It is not tied to the warranty purchased by the seller. We cannot proceed until you get the original Dell order number.
