About Digital Uniformity Correction
Every LCD panel will have some form of color and luminance non-uniformity across the screen. Even
though the panel used in the monitor has been carefully selected and sorted during production,
there will be some remaining non-uniformity. To reduce the impact of this, each NEC MultiSync PA
Series monitor is individually measured and characterized during production to map areas of non-
uniformity. This data is then used to build an internal three-dimensional correction table and stored
in the display. Screen non-uniformity is significantly reduced when this correction is applied using the
Digital Uniformity Correction circuit.
This circuit works by reducing the luminance levels of areas of the screen that are brighter than oth-
ers. This is done for red, green, and blue so that uniform color as well as brightness is achieved. As a
consequence of this correction, the maximum brightness or luminance from the display is reduced
when this feature is used. The level of Digital Uniformity Correction that is applied to the display can
be controlled using the Correction Level control and should be set to a level that gives the best bal-
ance of uniformity versus brightness reduction.
The PA Series will intelligently adapt the level of Digital Uniformity Correction as the Brightness
control is changed. If a Brightness level higher than that which can be achieved with the current Digi-
tal Uniformity Correction level is selected, then the correction level will be reduced in order to best
achieve the selected Brightness. A warning icon will be shown next to the Brightness control in this
case to indicate that the level of Digital Uniformity Correction has been reduced due to the current
Brightness setting.
