Today we will look at the monitor I2757FM from AOC from the year 2013. 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
The display is sized at 27 inches ( 68.4 cm on the diagonal). For books or documents, a portrait format layout is usually used because the reading flow decreases as the width of the text increases. For small diagonals, screens in 4:3 format have a clear advantage because they are better suited for display due to their height. In contrast, widescreen monitors are better suited for playing video games or displaying several documents side by side, for example. Depending on the application, it should be decided individually whether the aspect ratio of 1.778 : 1 is sufficient. The display is a AH panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 81 ppi. The pixel pitch is 0.311 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 I2757FM 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 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. 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 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 20000000 : 1 of dynamic contrast ratio for the monitor I2757FM 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
If you want to place the monitor described here on the desk without a wall mount, you should allow for 49.9 x 62.2 x 13 cm (HxWxD) of space. The device weighs in total (i.e. also measured with the stand) 5.7 kg.
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. It is possible to adjust the tilt angle of the monitor I2757FM according to personal preference to ensure ergonomic and comfortable viewing. The angle of inclination to the rear is 15. 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
- Flicker Free: AOC 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- 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 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 LG Display and has the model number LM270WF6-S2A2.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 25 w. The maximum power consumption (peak) specified for this monitor is 40 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. In ECO mode, the monitor consumes 15 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 maximum height at which the monitor may be operated, according to the manufacturer's specifications, is 3.657 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.
