Within this article we will take a closer look at the technical specifications of the H277HUsmidpx 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 is given in inches and measures the screen diagonal of the display. The monitor H277HUsmidpx has a display size of 27 inches ( 68.5 cm on the diagonal). It should be noted, however, that displays in this category can have different dimensions, since square monitors, for example, can have the same diagonal as a widescreen monitor. For books or documents, a portrait format layout is usually used because the reading flow decreases as the width of the text increases. For small diagonals, screens in 4:3 format have a clear advantage because they are better suited for display due to their height. In contrast, widescreen monitors are better suited for playing video games or displaying several documents side by side, for example. Depending on the application, it should be decided individually whether the aspect ratio of 1.778 : 1 is sufficient. 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 H277HUsmidpx is a monitor with a ratio of 90 % between usable and non-usable front surface. The display is a AH panel. The panel has a resolution of 2560 x 1440 px. The pixel density is 109 ppi. The pixel pitch is 0.233 mm. The continuous possible brightness specified by the manufacturer Acer is 350 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 H277HUsmidpx 31 khz to 89 khz. Vertically, however, the image renews at a minimum rate of 56 hz up to 75 hz. The minimum 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 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. The coverage of the Adobe RGB 1998 color space is 70 % according to the manufacturer. According to the manufacturer, the coverage of the SRGB color space is 97 %.
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 H277HUsmidpx 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
For the installation of the monitor, a space requirement of approximately 36.3 cm in height, 61.3 cm in width and 3.5 cm in depth is to be assumed.
If you want to place the monitor described here on the desk without a wall mount, you should allow for 43.9 x 61.3 x 21.7 cm (HxWxD) of space. The device weighs 4.5 kg with the stand in place. A wall mount should be designed for at least 4.1 kg to hold the H277HUsmidpx neatly and securely.
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 H277HUsmidpx 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 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.
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 H277HUsmidpx.
WiFi / Bluetooth
Power consumption
The maximum power consumption (peak) specified for this monitor is 90 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.
Environment
The monitor has a built-in ambient light sensor, which can be used, for example, to dynamically adjust the brightness of the monitor to the ambient conditions. The maximum storage temperature should be according to Acer 60 °C. Minimal were given by Acer -20 °C.
