Today we will look at the monitor EI491CR Sbmiiiphx from Acer from the year 2021. 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 display. It is 49 inches ( 1.244 m on the diagonal) large and should thus offer enough space for all contents according to Acer. 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 3.556 : 1 makes sense for the intended use case. 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 89.5 % 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 1080 px. The pixel density is 81 ppi. The pixel pitch is 0.311 mm. The continuous possible brightness specified by the manufacturer Acer is 400 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 EI491CR Sbmiiiphx 53.53 khz to 160.56 khz. Vertically, however, the image renews at a minimum rate of 48 hz up to 144 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 DCI-P3 color space is 90 %.
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 EI491CR Sbmiiiphx cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio. The monitor from Acer supports adaptive contrast management, dynamically adjusting the contrast ratio of the input signal to ensure razor-sharp image displays. Each scene is continuously analyzed by EI491CR Sbmiiiphx and the images are adjusted accordingly frame by frame. This analysis and dynamic adjustment of contrast is designed to enhance color quality and provide better black levels when displaying dark scenes and shaded/dark image sequences.
HDR
The monitor supports all HDR modes listed here:
- HDR 10
- HDR 400
screen design
The following dimensions must be planned for a free-standing stand without attached feet/stand: 37.5 cm x 1.198 m x 17.2 cm (HxWxD)
If you want to place the monitor described here on the desk without a wall mount, you should allow for 43.7 x 1.198 x 28 m (HxWxD) of space. The base itself has a depth of 28 cm. As for the weight, Acer states a total weight of 11.3 kg with stand. Without stand, the monitor weighs 9.3 kg. 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 9.5 cm. This value is always measured from the bottom edge of the screen.
Curved
The EI491CR Sbmiiiphx is a curved monitor with a curvature of 1.8 m
Rotate, tilt and swivel
The monitor from Acer cannot be rotated. The EI491CR Sbmiiiphx can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 15 degree. Pivoting to the right is possible up to 15 degree. It is possible to adjust the tilt angle of the monitor EI491CR Sbmiiiphx according to personal preference to ensure ergonomic and comfortable viewing. 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 Premium: By dynamically synchronizing the refresh rate of the EI491CR Sbmiiiphx with frame rate, AMD FreeSync Premium minimizes judder and ensures smooth and enjoyable gaming. In addition, AMD FreeSync Premium guarantees that the monitor operates at a minimum of 120Hz at FHD and low framerate compensation (LFC) is available. The monitor earns the Pro with HDR support.
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 EI491CR Sbmiiiphx.
WiFi / Bluetooth
Power consumption
The average consumption was given by Acer as 9.6 w. The maximum power consumption (peak) specified for this monitor is 90 w. In standby mode, the device consumes approximately 0.45 w. When switched off, on the other hand, the monitor consumes only 0.35 w. EI491CR Sbmiiiphx supports a static ECO mode, which for example lowers the refresh rate, reduces brightness and disables AI functions to save energy. 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
During operation, the ambient temperature must not exceed 35 °C , to ensure full functionality. Below a temperature of 5 °C , the monitor from Acer should again not be used. The humidity must not exceed 80 percent. At least, however, 20 percent humidity.
