Today we will look at the monitor MultiSync EA304WMi-BK-SV 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
29 inches ( 75.6 cm on the diagonal) offer sufficient space for texts in any office applications, for example. The size specification of a monitor refers to the screen diagonal, which is usually specified in inches. It is only comparable to a limited extent for different formats. For example, a conventional 4:3 monitor with the same screen diagonal has 6% less width, but 13% more height and a total of 7% more surface area than a monitor in 16:10 format. Despite the difference in working area, wider monitors are better suited for consuming games or current movies, for example. It is also easier to display several documents simultaneously on widescreen monitors. So, it depends on the current use case whether the aspect ratio of 1.6 : 1 makes sense for the intended use case. Approximately 83.7 % of the front of the monitor is taken up by the display, while the remaining area consists of screen edges that cannot display any image information. If you want to set up several monitors next to each other, it is advisable to choose monitors with narrow edges. The display is a AH panel. The panel has a resolution of 2560 x 1600 px. The pixel density is 101 ppi. The pixel pitch is 0.251 mm. The continuous possible brightness specified by the manufacturer NEC is 350 nt. The panel is illuminated by GB-r LED. 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 EA304WMi-BK-SV 31.5 khz to 98.7 khz. Vertically, however, the image renews at a minimum rate of 56 hz up to 75 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 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. In contrast to the static contrast ratio, the dynamic contrast ratio changes the brightness of the panel itself in addition to the difference measurement from black to white. In addition to the difference between the brightest and the darkest pixel, the backlight is thus changed. Since the brightness of the panel may not be able to be adjusted exactly to a single pixel, a so-called halo effect is possible. The value of 2000000 : 1 of dynamic contrast ratio for the monitor MultiSync EA304WMi-BK-SV cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio.
HDR
The monitor supports all HDR modes listed here:
screen design
The monitor has a width of 68.6 cm without its attached stand/stand. The height is dimensioned at about 44.6 cm , while the for the depth of the monitor should be kept free at about 7.5 cm.
The size of the monitor (stand included) is 47.2 x 68.7 x 23 cm (HxWxD). The device weighs 10.9 kg with the stand in place. Without stand, the monitor weighs 7.8 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 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 EA304WMi-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. The tilt of the monitor MultiSync EA304WMi-BK-SV can be individually adjusted to optimize the viewing angle and increase comfort during use. The angle of inclination to the rear is 30. The monitor can be tilted forward by 5 degree.
Ports
The monitor can be connected via 1 VGA 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.

- Picture by Picture mode
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 LM300WQ6-SLA1.
WiFi / Bluetooth
Power consumption
The average consumption figure for MultiSync EA304WMi-BK-SV is 63 w. The maximum power consumption (peak) specified for this monitor is 83 w. In standby mode, the device consumes approximately 0.47 w. When switched off, on the other hand, the monitor consumes only 0.47 w. MultiSync EA304WMi-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 48 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. For temperature, the maximum permissible ambient temperature is 35 °C. 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, 20 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.
