Within this article we will take a closer look at the technical specifications of the ET322QR 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 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). 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 ET322QR from Acer faces an aspect ratio of 1.778 : 1. The display is a VA panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 69 ppi. The pixel pitch is 0.364 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. Vertically, however, the image renews at a minimum rate of 75 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 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 ET322QR 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
The size of the monitor (stand included) is 52.8 x 72.1 x 24.6 cm (HxWxD). The device weighs in total (i.e. also measured with the stand) 7.1 kg.
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 ET322QR offers the option of adjusting the tilt as required to create an ergonomic working environment and reduce visual fatigue. The angle of inclination to the rear is 13. The monitor can be tilted forward by 4 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.
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 ET322QR.
WiFi / Bluetooth
Power consumption
The average consumption was given by Acer as 30 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.5 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.
