Advanced Menu in default position:

Tag#1
The first page of Advanced menu offers more options. One of additional options is Low Brightness Mode.

The 2490 has three levels of brightness regulation.
The first is default level that has no special name, let's call it Standard.
The access to the second and the third levels of brightness is found on the first page of Advanced menu.
Low brightness mode has 3 positions: Off, On and Advance.
"On" "digitally" reduces brightness of white by 50%.
"Advance" applies further 50% reduction of brightness of white.
Low brightness mode reduces brightness of white only. Brightness of black remains "standard".
While in Low brightness mode, further regulation is done by backlight with the use of regular Brightness control.
"Auto Luminance" stabilizes brightness and colors. It's one of NEC's smart technologies available for professional use.

The unique NEC 90-series scalar is operated from here.

Tag#6
Color Control.
There are sRGB and Native modes ("N") here as well as several adjustable color presets. You can adjust: Temperature, White balance, then hue, color depth and brightness for each of primary and secondary colors. That's a Pro feature.
"P" mode stand for "Programmable". This mode is for hardware (monitor LUT) calibration.

Tag#7
Side border color is regulated from here. So-called "black bars" can be painted any gray tone from white to black.
Colorcomp improves brightness and color uniformity.

Advanced menu comprises totally 14 tags: 1-9 and A-E.
We will talk about the misterious Tag E little later.


A special software called NaViSet can be downloaded from here.
This is a variation of OSM that can be operated with no touch of monitor controls buttons. It duplicates many of OSM controls but not all of them.
