Product image for EB225Q

Today we will look at the monitor EB225Q 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

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 EB225Q has a display size of 21 inches ( 54.6 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. The size specification of a monitor refers to the screen diagonal, which is usually specified in inches. It is only comparable to a limited extent for different formats. For example, a conventional 4:3 monitor with the same screen diagonal has 6% less width, but 13% more height and a total of 7% more surface area than a monitor in 16:10 format. Despite the difference in working area, wider monitors are better suited for consuming games or current movies, for example. It is also easier to display several documents simultaneously on widescreen monitors. So, it depends on the current use case whether the aspect ratio of 1.778 : 1 makes sense for the intended use case. Around 86.6 % of the front surface of the monitor consists of the display, while the rest is made up of screen edges that cannot display images. If you want to place several monitors next to each other, it is advisable to prefer those with narrow edges. The display is a IPS panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 102 ppi. The pixel pitch is 0.248 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 EB225Q 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 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 EB225Q 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 monitor has a width of 50 cm without its attached stand/stand. The height is dimensioned at about 29.4 cm , while the for the depth of the monitor should be kept free at about 4.5 cm.
The size of the monitor (stand included) is 36.2 x 50 x 17.6 cm (HxWxD). The device weighs 3.1 kg with the stand in place. A wall mount should be designed for at least 2.7 kg to hold the EB225Q neatly and securely. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting.

Rotate, tilt and swivel

The monitor from Acer cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. The monitor EB225Q can be tilted. The angle of inclination to the rear is 18. The monitor can be tilted forward by 3 degree.

Ports

The monitor can be connected via 1 VGA ports.

camera

This monitor does not have a camera.

Features

  • 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 EB225Q.

WiFi / Bluetooth

Power consumption

The average consumption was given by Acer as 13 w. The maximum power consumption (peak) specified for this monitor is 20 w. In standby mode, the device consumes approximately 0.15 w. When switched off, on the other hand, the monitor consumes only 0.15 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.
