In Microsoft SQL Server Management Studio Create a new view and use this:
SELECT dbo.tblComputers.Username, dbo.tblComputers.Computername, dbo.tblComputerSystemProduct.IdentifyingNumber,
dbo.tblComputerSystemProduct.Vendor, dbo.tblComputerSystemProduct.Name, dbo.tblDesktopMonitor.MonitorManufacturer
FROM dbo.tblComputers INNER JOIN
dbo.tblComputerSystemProduct ON dbo.tblComputers.Computername = dbo.tblComputerSystemProduct.Computername INNER JOIN
dbo.tblDesktopMonitor ON dbo.tblComputers.Computername = dbo.tblDesktopMonitor.Computername
Save it, view it and copy the "cells" into an Excel sheet.
There isnt a monitor model or serial number field, i dont think it's possible to get one either.
