There is no information on the monitor(s) that are connected to the workstation in the inventory. This info can be found in the EDID data (https://en.wikipedia.org/wiki/Extended_Display_Identification_Data).
It would be very usefull to have this data in the inventory database.
We recently had a project where we had to replace 2000 17" monitors by new 24" monitors. Finding those 17" monitors was not an easy task without inventory data.
