Within this article we will take a closer look at the technical specifications of the Q27V4 monitor from AOC. For this we will talk about all possible categories that could be relevant. To start with, we will look at the display, talk about the design and in the next section we will go into the features of the monitor. Other features such as power consumption, connectors and certifications will follow later in the text.
Display
The monitor belongs to the device class 27 inches ( 68.5 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. Around 89.7 % 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 IPS panel. The panel has a resolution of 2560 x 1440 px. The pixel density is 108 ppi. The pixel pitch is 0.233 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 Q27V4 30 khz to 114 khz. Vertically, however, the image renews at a minimum rate of 48 hz up to 75 hz. The minimum response time of the monitor is ms.
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 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 Q27V4 cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio. The monitor from AOC supports adaptive contrast management, dynamically adjusting the contrast ratio of the input signal to ensure razor-sharp image displays. Each scene is continuously analyzed by Q27V4 and the images are adjusted accordingly frame by frame. This analysis and dynamic adjustment of contrast is designed to enhance color quality and provide better black levels when displaying dark scenes and shaded/dark image sequences.

screen design
AOC Specifies the following dimensions for the monitor Q27V4 without stand/feet: 36.4 cm x 61.3 cm x 4.6 cm (HxWxD)
The size of the Q27V4 on the desk is likely to be particularly relevant for most users. AOC specifies a space requirement of 42.8 x 61.3 x 21.4 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 4.77 kg with the stand screwed in. Without stand, the monitor weighs 3.69 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 8 cm. This value is always measured from the bottom edge of the screen.
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 Q27V4 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 23. The monitor can be tilted forward by 5 degree.

Features
- Flicker Free: AOC 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
Anyone who works a lot on the computer spends many hours a day in front of the screen. Excessive screen work can damage the eyes. This effect can be particularly pronounced during the darker hours and in the winter months. Many monitor manufacturers have now reacted and offer technologies and settings to reduce the blue component, which is primarily controversial. Depending on the manufacturer, these can be called "Low Blue Light", "Low Blue Light Technology", "SoftBlue" or even "Eye Saver Mode" and function differently. However, it is only important that AOC offers a technology to reduce the blue content in its monitor Q27V4.

Power consumption
On average, the monitor consumes approximately 26 w. In standby mode, the device consumes approximately 0.3 w. When switched off, on the other hand, the monitor consumes only 0.3 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 2 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 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 90 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to AOC 60 °C. Minimal were given by AOC -20 °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 46.1 x 68.3 x 16.7 cm (height x width x depth). The box together with the monitor weighs about 7.15 kg.
