How to interpret screen grades
| Grade | Screen criteria |
|---|---|
| Grade Premium | Near-perfect condition. Minimal wear or one to two very fine scratches may exist. With the screen on, no marks, lines, discolouration or dead pixels are accepted. |
| Grade A | Similar to Grade Premium, but may show minor visible imperfections and fine scratches noticeable at certain angles. Deep scratches are not accepted. |
| Grade AB | Intermediate level: follows Grade A and Grade B criteria. |
| Grade B | May show slight key marks and fine scratches. One to two dead pixels and small dark areas are permitted. |
| Grade BC | Intermediate level: follows Grade B and Grade C criteria. |
| Grade C Plus / Grade C | May show noticeable wear, key marks, scratches where light does not pass, dust in corners, one to two dead pixels and dark areas. |
| Functional with note | The device works but has a specific imperfection described in the listing, such as edge delamination, a bright spot or three to six dead pixels. |
| Grade E | Includes serious faults such as pronounced delamination, non-functional screen or white spots covering a large part of the screen. |
Functional with note and Grade E are not part of the visual scale: they describe the functional condition of the screen.
