Within this article we will take a closer look at the technical specifications of the EI431CR 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
Any multimedia content can be displayed on 43 inches ( 1.102 m on the diagonal). As already known, two monitors with different outer dimensions can have the same screen diagonal. In the case of the monitor EI431CR , we find an aspect ratio of 3.2 to 1. This means that for every 1 pixels in height, 3.2 pixels in width are added. For comparison: A classic CRT monitor had an aspect ratio of 4:3. Besides the aspect ratios and the specified screen diagonal, the ratio between the monitor surface and the actual display is probably also relevant for some enthusiasts. This is the general ratio of non-display to display. In other words, 87.6 % of the monitor's front area consists of the display. The remaining percent consists of screen edges and cannot display an image. If you want to place several monitors next to each other, you should make sure that the edges are as small as possible. The display is a SVA panel. The panel has a resolution of 3840 x 1200 px. The pixel density is 92 ppi. The pixel pitch is 0.274 mm. The continuous possible brightness specified by the manufacturer Acer is 320 cd/m2. The maximum brightness of the monitor is 400 nt on the panel. 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 EI431CR 57.6 khz to 172.8 khz. Vertically, however, the image renews at a minimum rate of 48 hz up to 120 hz. The minimum response time of the monitor is ms. The display panel is Anti-glare/Matte.
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 DCI-P3 color space is 88 %. According to the manufacturer, the coverage of the SRGB color space is 99 %.
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 EI431CR 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 400
screen design
The monitor has a width of 1.06 m without its attached stand/stand. The height is dimensioned at about 37.2 cm , while the for the depth of the monitor should be kept free at about 15.2 cm.
The size of the EI431CR on the desk is likely to be particularly relevant for most users. Acer specifies a space requirement of 46.2 x 1.06 x 24.8 m (HxWxD) with the included stand. If you want to place the monitor on a table or even transport it, you should expect a weight of 10.12 kg with the stand screwed in. Without stand, the monitor weighs 7.98 kg. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting.
Curved
The EI431CR is a curved monitor with a curvature of 1.8 m
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. Thanks to the tilt function of the EI431CR monitor, the screen position can be flexibly adjusted to minimize dazzling light sources and ensure optimum visibility. The angle of inclination to the rear is 15. 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 3 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 EI431CR with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
- Picture by Picture mode
- Picture in Picture mode
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 EI431CR.
WiFi / Bluetooth
Power consumption
In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.5 w. In ECO mode, the monitor consumes 90 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.
Environment
Packaging
The box together with the monitor weighs about 13.3 kg.
