Today we will look at the monitor B247W from Acer from the year 2018. 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
Texts, videos and/or other applications can be displayed on the 24 inches ( 60.9 cm on the diagonal) of the monitor. As already known, two monitors with different outer dimensions can have the same screen diagonal. In the case of the monitor B247W , we find an aspect ratio of 1.6 to 1. This means that for every 1 pixels in height, 1.6 pixels in width are added. For comparison: A classic CRT monitor had an aspect ratio of 4:3. The display is a IPS panel. The panel has a resolution of 1920 x 1200 px. The pixel density is 94 ppi. The pixel pitch is 0.27 mm. The continuous possible brightness specified by the manufacturer Acer is 300 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 B247W 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 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 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. 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 B247W 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 size of the monitor (stand included) is 39 x 53.3 x 20.8 cm (HxWxD). The device weighs in total (i.e. also measured with the stand) 6.2 kg. 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 B247W can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 45 degree. Pivoting to the right is possible up to 45 degree. The monitor B247W can be tilted. The angle of inclination to the rear is 25. 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.
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.
- AMD FreeSync: By dynamically synchronizing the refresh rate of the B247W 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 B247W.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 17 w. In standby mode, the device consumes approximately 0.39 w. When switched off, on the other hand, the monitor consumes only 0.27 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.
