Today we will look at the monitor CB271HK from Acer from the year 2016. 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
Games, texts, videos and/or other applications can be displayed on the monitor's 27 inches ( 68.5 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 CB271HK from Acer 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 CB271HK is a monitor with a ratio of 86.5 % 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 163 ppi. The pixel pitch is 0.155 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 178 ° (horizontal) viewing angle. Acer promises stable color reproduction moreover within a 178 ° vertical angle. Vertically, however, the image renews at a minimum rate of 60 hz up to 60 hz. The minimum response time of the monitor is 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 %. 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 Acer has a static contrast ratio of 1000 : 1 , according to the manufacturer.
HDR
The monitor supports all HDR modes listed here:
screen design
Without the stand, the monitor comes with a width of 62.4 cm , a height of 37 cm and about 6.4 cm.
The size of the monitor (stand included) is 54.4 x 62.4 x 23.7 cm (HxWxD). The device weighs in total (i.e. also measured with the stand) 7.9 kg. According to Acer , you can expect a weight of about 4.99 kg without the stand. 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 0 degree. To the right, the monitor can be rotated by 90 degree. The CB271HK 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 CB271HK can be tilted. The angle of inclination to the rear is 35. The monitor can be tilted forward by 5 degree.
Ports
camera
This monitor does not have a camera.
Loudspeaker
The monitor from Acer has integrated speakers, for playing sounds, music or speech. The sound is emitted via 2 speakers, which are integrated into the device. Each of the built-in speakers has a contingent of 2 w power.
Features
- Flicker Free: Acer 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- Picture by Picture mode
- Picture in Picture mode
WiFi / Bluetooth
Power consumption
The average consumption was given by Acer as 7.5 w. The maximum power consumption (peak) specified for this monitor is 60 w. In standby mode, the device consumes approximately 0.42 w. When switched off, on the other hand, the monitor consumes only 0.39 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.
