Display, power consumption, dimensions, technologies used, connections, certifications, comfort features. All these keywords can be relevant for a purchase decision, but an exact comparison is often difficult. For this reason, we will summarize as many of the mentioned specifications as possible in an understandable form in the course of this article. Let's start with the most important component of the C2789FH8 from AOC.
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 C2789FH8 has a display size of 27 inches ( 68.5 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. Let's keep it short and sweet. The monitor has an aspect ratio of 1.778 : 1. The display is a VA 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 C2789FH8 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 90 %. According to the manufacturer, the coverage of the SRGB color space is 100 %.
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 500000000 : 1 of dynamic contrast ratio for the monitor C2789FH8 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 45.2 x 61.2 x 17.9 cm (HxWxD) of space. If you want to place the monitor on a table or even transport it, you should expect a weight of 5.8 kg with the stand screwed in. The monitor C2789FH8 without the stand weighs 3.96 kg. This weight reduction should be taken into account for wall or arm mounting, since monitor arms have a maximum load capacity.
Curved
The C2789FH8 is a curved monitor with a curvature of 1.8 m
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 C2789FH8 according to personal preference to ensure ergonomic and comfortable viewing. The angle of inclination to the rear is 21. The monitor can be tilted forward by 3 degree.
Ports
The monitor can be connected via 1 VGA ports.
camera
This monitor does not have a camera.
Loudspeaker
Features
- Flicker Free: AOC 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- AMD FreeSync: By dynamically synchronizing the refresh rate of the C2789FH8 with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
- The display/monitor supports Frame Rate Compensation.
WiFi / Bluetooth
Power consumption
The average consumption figure for C2789FH8 is 30 w. The maximum power consumption (peak) specified for this monitor is 35 w. In standby mode, the device consumes approximately 0.6 w. When switched off, on the other hand, the monitor consumes only 0.2 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 3.658 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 55 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.
