Within this article we will take a closer look at the technical specifications of the CBA272 bir monitor from Acer. 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
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 CBA272 bir 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. 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 CBA272 bir from Acer faces an aspect ratio of 1.778 : 1. Approximately 87.9 % of the front surface of the monitor is covered by the display, while the remaining area consists of screen edges that do not allow any image output. If you want to set up several monitors next to each other, it is advisable to prefer models with the narrowest possible edges. The display is a IPS 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 Acer is 250 cd/m2. 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. Acer promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the CBA272 bir 30 khz to 85 khz. Vertically, however, the image renews at a minimum rate of 48 hz up to 75 hz. 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 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 CBA272 bir 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
The following dimensions must be planned for a free-standing stand without attached feet/stand: 36.6 cm x 62.2 cm x 6.8 cm (HxWxD)
The size of the CBA272 bir on the desk is likely to be particularly relevant for most users. Acer specifies a space requirement of 40.5 x 62.2 x 23.3 cm (HxWxD) with the included stand. The base itself has a depth of 23.3 cm. The device weighs 6.4 kg with the stand in place. A wall mount should be designed for at least 4.85 kg to hold the CBA272 bir neatly and securely. 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 12 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 0 degree. To the right, the monitor can be rotated by 90 degree. The CBA272 bir can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 180 degree. Pivoting to the right is possible up to 180 degree. It is possible to adjust the tilt angle of the monitor CBA272 bir according to personal preference to ensure ergonomic and comfortable viewing. The angle of inclination to the rear is 20. 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.

Features
- Flicker Free: Acer '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 CBA272 bir with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
- The display/monitor supports Frame Rate Compensation.
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 Acer offers a technology to reduce the blue content in its monitor CBA272 bir.
WiFi / Bluetooth
Power consumption
The average consumption figure for CBA272 bir is 22 w. The maximum power consumption (peak) specified for this monitor is 35 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.45 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.
