Today we will look at the monitor M2470SWH from AOC 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
Let's start with the size of the actual display. This is given in inches and measures the screen diagonal of the display. The monitor M2470SWH has a display size of 23 inches ( 59.9 cm on the diagonal). It should be noted, however, that displays in this category can have different dimensions, since square monitors, for example, can have the same diagonal as a widescreen monitor. 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 1.778 : 1 makes sense for the intended use case. Around 81.9 % of the front surface of the monitor consists of the display, while the rest is made up of screen edges that cannot display images. If you want to place several monitors next to each other, it is advisable to prefer those with narrow edges. The display is a Super panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 93 ppi. The pixel pitch is 0.272 mm. The continuous possible brightness specified by the manufacturer AOC is 250 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. AOC promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the M2470SWH 30 khz to 83 khz. Vertically, however, the image renews at a minimum rate of 50 hz up to 76 hz. 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 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. According to the manufacturer, the coverage of the NTSC 1953 color space is 72 %.
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 AOC has a static contrast ratio of 3000 : 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 50000000 : 1 of dynamic contrast ratio for the monitor M2470SWH 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 55.1 cm without its attached stand/stand. The height is dimensioned at about 33.8 cm , while the for the depth of the monitor should be kept free at about 5.3 cm.
The size of the M2470SWH on the desk is likely to be particularly relevant for most users. AOC specifies a space requirement of 40 x 55.1 x 22.1 cm (HxWxD) with the included stand. If you want to place the monitor on a table or even transport it, you should expect a weight of 4.9 kg with the stand screwed in. According to AOC , you can expect a weight of about 3.4 kg without the stand. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting.
Rotate, tilt and swivel
The monitor from AOC cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. Thanks to the tilt function of the M2470SWH 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 25. 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 AOC 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 2 w power.
Features
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 AOC 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 Innolux and has the model number M236HJJ-???.
WiFi / Bluetooth
Power consumption
The average consumption was given by AOC as 24 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.37 w. In ECO mode, the monitor consumes 18 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 1.31 amps specified. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
The maximum height at which the monitor may be operated, according to the manufacturer's specifications, is 5 km. During operation, the ambient temperature must not exceed 40 °C , to ensure full functionality. Below a temperature of 0 °C , the monitor from AOC should again not be used. The humidity must not exceed 85 percent. At least, however, 10 percent humidity. The monitor may be stored at a maximum humidity of 93 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to AOC 55 °C. Minimal were given by AOC -25 °C. According to the manufacturer, the monitor may be stored at a maximum height of 12.192 km.
Packaging
The monitor is packaged in a cardboard box measuring 43.5 x 62 x 12.7 cm (height x width x depth). The box together with the monitor weighs about 5.21 kg.
