Today we will look at the monitor ET322QK Bbmiiprx 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 information is given in inches and measures the screen diagonal of the display. It can happen that displays with the same size specification have different dimensions, since square monitors, for example, can belong to the same category as a widescreen monitor. The monitor from Acer in this article has a size of 31 inches ( 80.1 cm on the diagonal). While classic CRT monitors were built with a screen ratio of 4:3, this monitor has a ratio of 1.778 : 1 (width to height). In addition to the aspect ratios and the specified screen diagonal, some enthusiasts may also be interested in the ratio between the monitor surface and the actual display. This ratio describes the general relationship between non-display and display. In other words, approximately 87 % of the front surface of the monitor consists of the display, while the rest consists of screen edges and cannot display an image. When setting up several monitors next to each other, it is advisable to give preference to models with the narrowest possible edges. The display is a VA panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 139 ppi. The pixel pitch is 0.182 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 ET322QK Bbmiiprx 30 khz to 160 khz. Vertically, however, the image renews at a minimum rate of 40 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 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 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 3000 : 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 ET322QK Bbmiiprx 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:
- HDR 10
screen design
Acer Specifies the following dimensions for the monitor ET322QK Bbmiiprx without stand/feet: 43.1 cm x 72.9 cm x 7.8 cm (HxWxD)
If you want to place the monitor described here on the desk without a wall mount, you should allow for 52.1 x 72.9 x 22.7 cm (HxWxD) of space. If you want to place the monitor on a table or even transport it, you should expect a weight of 9.6 kg with the stand screwed in. The monitor ET322QK Bbmiiprx without the stand weighs 6.44 kg. This weight reduction should be taken into account for wall or arm mounting, since monitor arms have a maximum load capacity. 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 11.5 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 ET322QK Bbmiiprx can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 20 degree. Pivoting to the right is possible up to 20 degree. The monitor ET322QK Bbmiiprx can be tilted. The angle of inclination to the rear is 20. 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.
- AMD FreeSync: By dynamically synchronizing the refresh rate of the ET322QK Bbmiiprx 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 ET322QK Bbmiiprx.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 47 w. The maximum power consumption (peak) specified for this monitor is 62 w. In standby mode, the device consumes approximately 0.45 w. When switched off, on the other hand, the monitor consumes only 0.34 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.
