Introduction 
Modern monitors internally store data on their performance characteristics and capabilities in an 
abbreviated format. The information is called the monitor Extended Display Identification Data or EDID 
and is read by operating systems and video graphics cards to determine the optimum display properties 
for the system. The IBM T221 is a very advanced and flexible monitor and it exceeds the capab
