Direct input selection button is located on the front of the bezel.


Overall build quality
This unit has no defects.
Assembly quality is very good.
The panel sits tightly in the cabinet.
Initially some backlight uniformity irregularity was noted. After some time of use the panel became uniform.
The monitor does not produce any noise.
After hours of work the bottom of the panel is still cool to to touch, the top is warm.
After one year I managed to notice one stuck subpixel. That was done with the use of special software. It's not possible to find it with regular use.


Anti-Glare Coating
The purpose of this layer is self-explanatory.
A few words about so-called "cristalline" effect ("sparkly look", etc.)on the modern LCD monitors.
This will be a "some" chapter.
Every non-glossy panel has this effect to some degree.
Some IPS panels of the past had quite noticeable AG coating effect. Some modern PVA-based monitors have sparkly look as well.
Some misinformed forums posters believe that AG coating effect is a part of IPS technology. This is not true.
Some IPS panels still have it (30" panels). Some IPS panels are glossy with zero AG effect.
Modern 24-26" panels have, let's say, "normal" AG coating with "standard" AG effect.
The NEC 2490WUXi is one of them.
In comparison with older 20" IPS, the NEC 2490 AG coating is much more "neutral".

Sound
The multimedia soundbar is optional.
It is easily attached underneath the monitor.
The 2490 has on-board DC out for the soundbar.
Sound quality is mediocre as it can be expected for this kind of equipment. But it performs its role nicely: the working place is clean of stand-alone speakers.
The soundbar has volume control and headphones connector.
