Today we will look at the monitor MultiSync EA244UHD from NEC from the year 2014. 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
23 inches ( 60.4 cm on the diagonal) offer sufficient space for texts in any office applications, for example. While classic CRT monitors were built with a screen ratio of 4:3, this monitor has a ratio of 1.778 : 1 (width to height). In addition to the aspect ratios and the specified screen diagonal, some enthusiasts may also be interested in the ratio between the monitor surface and the actual display. This ratio describes the general relationship between non-display and display. In other words, approximately 83.7 % of the front surface of the monitor consists of the display, while the rest consists of screen edges and cannot display an image. When setting up several monitors next to each other, it is advisable to give preference to models with the narrowest possible edges. The display is a AH panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 185 ppi. The pixel pitch is 0.137 mm. The continuous possible brightness specified by the manufacturer NEC is 350 nt. The panel is illuminated by W-LED. The built-in panel ensures stable color reproduction of the image, even at deviating viewing angles, by means of its 176 ° (horizontal) viewing angle. NEC promises stable color reproduction moreover within a 176 ° vertical angle. The refresh rate is horizontally seen at the MultiSync EA244UHD 31.5 khz to 134 khz. Vertically, however, the image renews at a minimum rate of 30 hz up to 75 hz. 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 10 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 99 % according to the manufacturer. According to the manufacturer, the coverage of the NTSC 1953 color space is 94 %. According to the manufacturer, the coverage of the SRGB color space is 146 %.
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.

The monitor supports all HDR modes listed here:
screen design
Without the stand, the monitor comes with a width of 55.8 cm , a height of 33.4 cm and about 7.2 cm.
If you want to place the monitor described here on the desk without a wall mount, you should allow for 38.6 x 55.8 x 21.8 cm (HxWxD) of space. If you want to place the monitor on a table or even transport it, you should expect a weight of 8.7 kg with the stand screwed in. A wall mount should be designed for at least 5 kg to hold the MultiSync EA244UHD neatly and securely. 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 13 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 EA244UHD can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 170 degree. Pivoting to the right is possible up to 170 degree. The monitor MultiSync EA244UHD offers the option of adjusting the tilt as required to create an ergonomic working environment and reduce visual fatigue. The angle of inclination to the rear is 30. The monitor can be tilted forward by 5 degree.
Ports
camera
This monitor does not have a camera.
Loudspeaker
The monitor from NEC has integrated speakers, for playing sounds, music or speech. The sound is emitted via 2 speakers, which are integrated into the device. Each of the built-in speakers has a contingent of 1 w power.
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 LM238WR2.
WiFi / Bluetooth
Power consumption
The average consumption figure for MultiSync EA244UHD is 46 w. The maximum power consumption (peak) specified for this monitor is 79 w. When switched off, on the other hand, the monitor consumes only 0.33 w. In ECO mode, the monitor consumes 41 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 1.1 amps specified. 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 5 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 -20 °C. According to the manufacturer, the monitor may be stored at a maximum height of 12.192 km.
