Today we will look at the monitor MultiSync PA231W-BK-SV from NEC from the year 2010. Within this article, we will first take a closer look at the most important feature of a monitor -the display-, then the design, and in the next section we will go into the features of the monitor. Of course, power consumption, certifications, connectivity and other important details will also be considered.
Display
Any multimedia content can be displayed on 23 inches ( 58.4 cm on the diagonal). As already mentioned or known, monitors have a certain number of pixels in height and width. In most cases, this is not a 1:1 ratio, which is also the case with the monitor from NEC. This monitor has an aspect ratio of 1.778 : 1. This means that every 1.778 pixels in width 1 pixels in height are added. Approximately 83.1 % of the front surface of the monitor is taken up by the display, while the remaining part is screen edges that do not allow the image to be displayed. If you want to place several monitors next to each other, it is advisable to choose models with narrow edges. The display is a E panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 95 ppi. The pixel pitch is 0.265 mm. The continuous possible brightness specified by the manufacturer NEC is 270 nt. The panel is illuminated by CCFL. The built-in panel ensures stable color reproduction of the image, even at deviating viewing angles, by means of its 178 ° (horizontal) viewing angle. NEC promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the MultiSync PA231W-BK-SV 31.5 khz to 118.4 khz. Vertically, however, the image renews at a minimum rate of 50 hz up to 85 hz. The analog refresh rate of this monitor is 31.5 khz to 83 khz. The minimum response time of the monitor is ms. The average response time of the monitor is about ms. The display panel is Anti-glare/Matte (3H).
Color space
The panel has a bit depth of 8 per color channel, but what does that mean? The number of bits determines how many colors can be encoded for the individual pixels of the display. For an 8-bit panel, for example, this is 256 different colors (2^8 = 256). However, since we usually display three different colors per pixel at the same time, in theory about 16 million (256^3) different colors are possible by mixing the three pixels. A 10-bit panel could even display a billion colors. The coverage of the Adobe RGB 1998 color space is 75 % according to the manufacturer. According to the manufacturer, the coverage of the NTSC 1953 color space is 72 %. According to the manufacturer, the coverage of the SRGB color space is 102 %.
Contrast ratio
Contrast ratio is a common measurement used to represent the maximum relative differences in brightness between black and white. It describes the ability of a screen or projector to produce a high-contrast image and is the quotient of the maximum and minimum displayable luminance. The higher the values are away from each other, the stronger the quantitatively seen difference between black and white is set up, which in turn results in an improved image quality. This monitor from NEC has a static contrast ratio of 1000 : 1 , according to the manufacturer.
HDR
The monitor supports all HDR modes listed here:
screen design
The monitor has a width of 54.3 cm without its attached stand/stand. The height is dimensioned at about 32.2 cm , while the for the depth of the monitor should be kept free at about 7.3 cm.
The size of the monitor (stand included) is 33.7 x 54.3 x 22.8 cm (HxWxD). The device weighs 10.2 kg with the stand in place. Without stand, the monitor weighs 7 kg. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 15 cm. This value is always measured from the bottom edge of the screen.
Rotate, tilt and swivel
The monitor from NEC has a pivot function and can thus be rotated using the included stand. A rotation to the left is possible with up to 0 degree. To the right, the monitor can be rotated by 90 degree. The MultiSync PA231W-BK-SV can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 45 degree. Pivoting to the right is possible up to 45 degree. Thanks to the tilt function of the MultiSync PA231W-BK-SV monitor, the screen position can be flexibly adjusted to minimize dazzling light sources and ensure optimum visibility. The angle of inclination to the rear is 30. The monitor can be tilted forward by 5 degree.
Ports
The connection of a device via display port is supported.
camera
This monitor does not have a camera.
Loudspeaker
Features
- Picture by Picture mode
- Picture in Picture mode
- The display/monitor supports Frame Rate Compensation.
Panel manufacturer
Many manufacturers of monitors and TVs fall back on third-party manufacturers, such as Samsung or LG, when choosing the actual display (panel). Thus, many of the monitors have the same panel and, conversely, differ only in their design, additional functionalities, the software used and, of course, the price. Two monitors from NEC or another manufacturer with an identical panel do not necessarily have to have the same picture quality, but it is usually a first indicator for a purchase decision. The panel used here is originally from LG Display and has the model number LM230WF2-SLA1.
NEC has built hardware/software into the MultiSync PA231W-BK-SV to control different colored LEDs, most of which are located on the back of the device. Through intelligent control of the LEDs, colors of the image displayed on the monitor are projected onto the wall behind it, which is supposed to be easy on the eyes and at the same time make the image look more immersive. Depending on the manufacturer, this technology is called Ambilight, Ambiglow, Atmolight or HiLight.
WiFi / Bluetooth
Power consumption
The average consumption figure for MultiSync PA231W-BK-SV is 34 w. The maximum power consumption (peak) specified for this monitor is 46 w. When switched off, on the other hand, the monitor consumes only 0.2 w. MultiSync PA231W-BK-SV supports a static ECO mode, which for example lowers the refresh rate, reduces brightness and disables AI functions to save energy. In ECO mode, the monitor consumes 30 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
The monitor has a built-in ambient light sensor, which can be used, for example, to dynamically adjust the brightness of the monitor to the ambient conditions. The maximum height at which the monitor may be operated, according to the manufacturer's specifications, is 2 km. The maximum permissible ambient temperature is 35 °C during operation. Below a temperature of 5 °C , the monitor from NEC should again not be used. The humidity must not exceed 80 percent. At least, however, 30 percent humidity. The monitor may be stored at a maximum humidity of 85 percent. The minimum humidity during storage should not fall below 10 percent. The maximum storage temperature should be according to NEC 60 °C. Minimal were given by NEC -10 °c. According to the manufacturer, the monitor may be stored at a maximum height of 12.192 km.
