 "P" is "Professional".
 "U" line is a "UltraSharp"
 "UP" means UltraSharp with PremierColor, with factory calibration and wider color gamut. 
 "S" and "E" are a low-end, gaming and consumer displays.

The second set of numbers is the screen size in inches, often followed by the model year and a suffix, eg "FP" for "flat panel", "W" for "wide-screen"
