Within this article we will take a closer look at the technical specifications of the U28G2XU 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
Games, texts, videos and/or other applications can be displayed on the monitor's 28 inches ( 70.8 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 U28G2XU from AOC 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 U28G2XU is a monitor with a ratio of 90.3 % between usable and non-usable front surface. The display is a IPS panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 157 ppi. The pixel pitch is 0.161 mm. The continuous possible brightness specified by the manufacturer AOC is 320 nt. Above all, bright environments are a challenge for monitors. The brightness of the monitor is crucial for an accurate and color-true reproduction of the image to outshine the ambient light. The panel of the U28G2XU shines with a brightness of 460 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 U28G2XU 30 khz to 255 khz. Vertically, however, the image renews at a minimum rate of 48 hz up to 144 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. According to the manufacturer, the coverage of the DCI-P3 color space is 95 %. According to the manufacturer, the coverage of the NTSC 1953 color space is 108 %. According to the manufacturer, the coverage of the SRGB color space is 122 %.
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 80000000 : 1 of dynamic contrast ratio for the monitor U28G2XU 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:
- HDR 400
screen design
AOC Specifies the following dimensions for the monitor U28G2XU without stand/feet: 36.8 cm x 63.6 cm x 5.3 cm (HxWxD)
The size of the monitor (stand included) is 40.1 x 63.6 x 22.7 cm (HxWxD). The base itself has a depth of 22.7 cm. As for the weight, AOC states a total weight of 6.15 kg with stand. Without stand, the monitor weighs 4.81 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 AOC 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 U28G2XU can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 30 degree. Pivoting to the right is possible up to 30 degree. It is possible to adjust the tilt angle of the monitor U28G2XU according to personal preference to ensure ergonomic and comfortable viewing. 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.
- AMD FreeSync: By dynamically synchronizing the refresh rate of the U28G2XU with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
- Picture by Picture mode
- Picture in Picture mode
- Display Stream Compression
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 U28G2XU. The Adaptive Sync feature of the U28G2XU dynamically varies the monitor's refresh rate and responds to the game's required frame rates. The monitor from AOC supports the reduction of artifacts within dark image areas, which are caused by compression of the played video files, for example. Depending on the manufacturer, this technology is called Black Boost, Dark Boost, Black Stabilizer, Black Equalizer or Black Enhancement. Motion Blur Reduction (also referred to as Motion Blur Reduction Technology or Motion Blur Reduction Sync) is a feature of U28G2XU , which is used to reduce motion blur when objects move quickly on the screen. This is achieved through a combination of technologies such as backlight strobing, overdrive and others. This improves the response time of the pixels to reduce motion blur, which can be particularly beneficial for video games, action movies, or other content with fast movements. However, this feature can lead to brightness loss or flickering, so it is important to adjust the settings accordingly and choose depending on the application.
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 M280DCA-E7B AAS.
WiFi / Bluetooth
Power consumption
The average consumption was given by AOC as 45 w. In standby mode, the device consumes approximately 0.5 w. The monitor can be operated on a 110v power supply.
