Today we will look at the monitor MultiSync EA275WMi from NEC from the year 2015. 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 27 inches ( 68.4 cm on the diagonal). Television screens and monitors usually have an aspect ratio of 16:9 (approximately 1.78:1). More rarely, computer monitors are also found with an aspect ratio of 16:10.
Ultrawidemonitors are often manufactured with an aspect ratio of 21:9 (approximately 2.34:1). They are mainly used for computer games and as an alternative to two side-by-side screens. The first devices of this type came onto the market around 2014. Against this backdrop, the monitor MultiSync EA275WMi from NEC faces an aspect ratio of 1.778 : 1.
If you want to pay attention to special aesthetics or simply want to place several monitors next to each other, you should pay attention to the ratio between display and non-display. The MultiSync EA275WMi is a monitor with a ratio of 82.9 % between usable and non-usable front surface. The display is a AH panel. The panel has a resolution of 2560 x 1440 px. The pixel density is 109 ppi. The pixel pitch is 0.233 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 178 ° (horizontal) viewing angle. NEC promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the MultiSync EA275WMi 31.5 khz to 91 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 maximum response time of the monitor is 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.

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 20000 : 1 of dynamic contrast ratio for the monitor MultiSync EA275WMi 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 following dimensions must be planned for a free-standing stand without attached feet/stand: 37.7 cm x 63.9 cm x 7.2 cm (HxWxD)
The size of the monitor (stand included) is 41.7 x 63.9 x 23 cm (HxWxD). 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. Without stand, the monitor weighs 5.8 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 EA275WMi 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 EA275WMi can be tilted. 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

The monitor MultiSync EA275WMi supports upscaling of the input signal up to 4k resolution.

WiFi / Bluetooth

Power consumption

The average consumption was given by NEC as 47 w. The maximum power consumption (peak) specified for this monitor is 61 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.5 w. MultiSync EA275WMi 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 35 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 1.2 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.
