Today we will look at the monitor S277HK from Acer from the year 2014. 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 most important component of a monitor, the display. Depending on the aspect ratio of height and width, monitors can be rather wide or square, for example. Besides the pure physical dimensions, the resolution of the display and thus the quality of the display is also decisive here. For easy comparability, however, screen sizes are usually given in inches. This unit of measurement simply compares the diagonal length from the lower left to the upper right corner of the display and is thus universally applicable. This device has a screen diagonal of 27 inches ( 68.5 cm on the diagonal). 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. If you want to pay attention to special aesthetics or simply want to place several monitors next to each other, you should pay attention to the ratio between display and non-display. The S277HK is a monitor with a ratio of 80.2 % between usable and non-usable front surface. The display is a AHVA panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 163 ppi. The pixel pitch is 0.155 mm. The continuous possible brightness specified by the manufacturer Acer is 300 nt. 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 S277HK 31 khz to 135 khz. Vertically, however, the image renews at a minimum rate of 24 hz up to 75 hz. The minimum response time of the monitor is ms. The maximum response time of the monitor is ms. The average response time of the monitor is about 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 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 S277HK 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
Without the stand, the monitor comes with a width of 61.4 cm , a height of 40.6 cm and about 11.3 cm.
If you want to place the monitor described here on the desk without a wall mount, you should allow for 45.1 x 61.4 x 15.4 cm (HxWxD) of space. If you want to place the monitor on a table or even transport it, you should expect a weight of 5.4 kg with the stand screwed in. Without stand, the monitor weighs 4.94 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. Thanks to the tilt function of the S277HK 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 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.
- 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 S277HK.
Panel manufacturer
Many manufacturers of monitors and TVs fall back on third-party manufacturers, such as Samsung or LG, when choosing the actual display (panel). Thus, many of the monitors have the same panel and, conversely, differ only in their design, additional functionalities, the software used and, of course, the price. Two monitors from Acer or another manufacturer with an identical panel do not necessarily have to have the same picture quality, but it is usually a first indicator for a purchase decision. The panel used here is originally from AU Optronics and has the model number M270QAN01.1.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 9.87 w. The maximum power consumption (peak) specified for this monitor is 54 w. In standby mode, the device consumes approximately 0.47 w. When switched off, on the other hand, the monitor consumes only 0.4 w. In ECO mode, the monitor consumes 25 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 4.74 amps specified. The power grid has to supply a frequency of 50 hz to 60 hz.
