The monitors have three input connectors: one DVI-D (digital), one DVI-I (universal) and one D-Sub (analog). The latter seems redundant to me. It is currently leaving both monitors and graphics cards while the universal DVI-I allows to connect an analog source via a very simple adapter.
On the left of the interface connectors there is a power connector for optional Soundbar 90 speakers. The monitor itself is equipped with an integrated power adapter.
The monitor’s controls are placed in the bottom left corner of the case. The LED of the power indicator and the ambient lighting sensor are located here, too.
As you can see, the buttons have no labels, except for the Input button that selects the video input. But on your entering the onscreen menu, the labels light up right on the screen next to the buttons. This is done for the portrait mode: the position of the labels changes depending on the screen orientation (the Up – Down and Left – Right buttons change their places at that). This solution is arguable. For me, it is still more convenient to deal with ordinary labels even if they are turned around by 90 degrees.
The menu of the 2190 series resembles the menu of NEC’s modern consumer monitors, but only visually. It is much richer in various settings. The first menu item offers you ECO Mode (quick switching between several levels of backlight brightness), black level adjustment and automatic brightness adjustment besides traditional brightness and contrast settings.
The auto-brightness option can be used in two ways: depending on the onscreen image (this is in fact the same feature as consumer monitors’ dynamic contrast) or depending on the reading of the ambient lighting sensor. The latter option is more interesting, of course, as it allows the monitor to keep track of the intensity of lighting in your room and to automatically adjust the screen brightness for it.
The auto-adjustment works fine. It works with a small delay and changes brightness smoothly, not irritating your eyes and not reacting to an accidental shadow falling on the monitor’s screen. Before you enable this feature, you can specify the range brightness should be varied within.
The color temperature section is interesting, too. Like on any other monitor from NEC, it offers a few preset values, all of which can be adjusted manually (besides sRGB, which always means 6500K, “N”, which corresponds to the matrix’s parameters without any additional adjustment, and “P”, which is set up by software from the PC). An important thing, it is the temperature that is adjusted, in all the available range stepping 100K. With ordinary monitors, you have to set up the color temperature by moving three sliders responsible for the levels of red, green and blue, which is not convenient. The discussed monitors offer this kind of adjustment, too. Just select the Custom item instead of a temperature value.
Moreover, the monitors allow to set up hue (by six color coordinates – the photograph above shows this option with respect to red), saturation (for each of the six colors, too), and brightness (not the same brightness as on the menu’s first tab, but the brightness of each basic color independently). All this provides exceptional opportunities for manual setting-up of the monitor even without a hardware calibrator. You need appropriate skills for that, though. Otherwise, the manual setup may as likely worsen the color reproduction as not.
An interesting option in the main menu is Colorcomp which enables compensation of the irregularity of backlight. The manufacturer doesn’t promise any great effect from it, and the two samples of monitors (an LCD2190UXi and an LCD2190UXp) I dealt with both proved to have a very uniform backlight I could hardly find fault with.
I said “main menu” in the previous paragraph because the monitor has a second, extended menu which is accessed by turning the monitor off with the Power button and then turning it on while keeping the Select button pressed.
