The previous setting was related to the overall dimension and not to the
active display area.
In the "PHYSICAL SPECIFICATIONS" section, the datasheet shows the
following parameters:

 ----------------------------------------------------------
|       Item        |         Specifications        | unit |
 ----------------------------------------------------------
| Display area      | 98.7 (W) x 57.5 (H)           |  mm  |
 ----------------------------------------------------------
| Overall dimension | 105.5(W) x 67.2(H) x 4.96(D)  |  mm  |
 ----------------------------------------------------------
