Dell monitors have cryptic model names/codes such as U2312f or E2318H.

The model names is made up of (at least) four elements, exemplified below:

Category Diagonal Length Two digits Final letters
E 23 18 H

Here's what I know about these:

  1. Category (1 character):
    E (Economy) / T (Touch) / P (Professional) / S (Studio) / U (Ultrasharp)
  2. Diagonal length in inches (including the bezel if I'm not mistaken)
  3. A two-digit number
  4. Potential combination of several extra letters - upper or lowercase, e.g. H, M, t, f.

Can someone explain the meaning of components 3 and 4?
