Today we will look at the monitor XB280HK from Acer from the year 2014. 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 28 inches ( 71.1 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. Approximately 84.2 % of the front of the monitor is taken up by the display, while the remaining area consists of screen edges that cannot display any image information. If you want to set up several monitors next to each other, it is advisable to choose monitors with narrow edges. The display is a TN panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 157 ppi. The pixel pitch is 0.162 mm. The continuous possible brightness specified by the manufacturer Acer is 300 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 170 ° (horizontal) viewing angle. Acer promises stable color reproduction moreover within a 160 ° vertical angle. The refresh rate is horizontally seen at the XB280HK 30 khz to 80 khz. Vertically, however, the image renews at a minimum rate of 55 hz up to 75 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 10 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 Acer 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 100000000 : 1 of dynamic contrast ratio for the monitor XB280HK 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 supports all HDR modes listed here:
screen design
Without the stand, the monitor comes with a width of 65.8 cm , a height of 38.1 cm and about 6.4 cm.
The size of the XB280HK on the desk is likely to be particularly relevant for most users. Acer specifies a space requirement of 40.8 x 65.8 x 24.4 cm (HxWxD) with the included stand. As for the weight, Acer states a total weight of 7.8 kg with stand. Without stand, the monitor weighs 5.2 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 15 cm. This value is always measured from the bottom edge of the screen.
Rotate, tilt and swivel
The monitor from Acer has a pivot function and can thus be rotated using the included stand. A rotation to the left is possible with up to 90 degree. To the right, the monitor can be rotated by 90 degree. The XB280HK can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 60 degree. Pivoting to the right is possible up to 60 degree. The monitor XB280HK offers the option of adjusting the tilt as required to create an ergonomic working environment and reduce visual fatigue. The angle of inclination to the rear is 35. The monitor can be tilted forward by 5 degree.

Features
- Flicker Free: Acer 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- Nvidia G-SYNC
- 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 Acer 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 M280DGJ-L30.
WiFi / Bluetooth
Power consumption
The average consumption figure for XB280HK is 2.5 w. In standby mode, the device consumes approximately 0.48 w. When switched off, on the other hand, the monitor consumes only 0.4 w. In ECO mode, the monitor consumes 22 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.
