excellent screen Iiyama but with negatives

The item delivered by mail reached me sooner than expected in very good condition in the original packaging. The installation was carried out without problems. It was a replacement of an old same brand monitor with the switch was almost HS. The width of the screen allows the simultaneous display of two A4 pages. The definition of the slab is excellent and flawless. The model chosen allows a comfortable adjustment of the screen height and angle as on the former model.
Negative points:
The number of USB ports is nevertheless smaller than the previous model and requires to use a hub for adding devices. But the main defect is discovered door on the settings of the screen settings which are more delicate and above all ... unexplained in the instructions supplied! This is not acceptable! It must indeed play several small buttons on the underside and invisible from the normal position of the! This silly provision (which did not exist in the previous model) must be reported, as it makes difficult the necessary adjustments if one simply wants to adapt the brightness of the panel to that of the atmosphere, the factory settings being too violent! Moreover, the setting menus will automatically disappear in a flash ... and this adds to the difficulty! This is why I only give 4 out of 5 stars.
