Within this article we will take a closer look at the technical specifications of the G-Master GB2770HSU-B1 monitor from Iiyama. 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 display. It is 27 inches ( 68.5 cm on the diagonal) large and should thus offer enough space for all contents according to Iiyama. While classic CRT monitors were built with a screen ratio of 4:3, this monitor has a ratio of 1.778 : 1 (width to height). The display is a IPS panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 81 ppi. The pixel pitch is 0.311 mm. The continuous possible brightness specified by the manufacturer Iiyama is 250 nt. The monitor's panel reaches a peak brightness of 290 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. Iiyama promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the G-Master GB2770HSU-B1 15 khz to 225 khz. Vertically, however, the image renews at a minimum rate of 48 hz up to 165 hz. 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.
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 Iiyama has a static contrast ratio of 1100 : 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 80000000 : 1 of dynamic contrast ratio for the monitor G-Master GB2770HSU-B1 cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio.

screen design
The size of the G-Master GB2770HSU-B1 on the desk is likely to be particularly relevant for most users. Iiyama specifies a space requirement of 41.6 x 61.2 x 25.6 cm (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 5.2 kg with the stand screwed in. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 13 cm. This value is always measured from the bottom edge of the screen.
Rotate, tilt and swivel
The monitor from Iiyama has a pivot function and can thus be rotated using the included stand. A rotation to the left is possible with up to 90 degree. To the right, the monitor can be rotated by 90 degree. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. It is possible to adjust the tilt angle of the monitor G-Master GB2770HSU-B1 according to personal preference to ensure ergonomic and comfortable viewing. The angle of inclination to the rear is 18. The monitor can be tilted forward by 3 degree.
Ports
camera
This monitor does not have a camera.
Loudspeaker
The monitor from Iiyama 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: Iiyama '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 G-Master GB2770HSU-B1 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 display/monitor supports Frame Rate Compensation.
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 Iiyama offers a technology to reduce the blue content in its monitor G-Master GB2770HSU-B1. The monitor from Iiyama supports the reduction of artifacts within dark image areas, which are caused by compression of the played video files, for example. Depending on the manufacturer, this technology is called Black Boost, Dark Boost, Black Stabilizer, Black Equalizer or Black Enhancement.

Power consumption
The average consumption was given by Iiyama as 22 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.3 w. G-Master GB2770HSU-B1 supports a static ECO mode, which for example lowers the refresh rate, reduces brightness and disables AI functions to save energy. In ECO mode, the monitor consumes 18.7 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 1.5 amps specified. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
For temperature, the maximum permissible ambient temperature is 35 °C. Below a temperature of 5 °C , the monitor from Iiyama should again not be used. The humidity must not exceed 80 percent. At least, however, 10 percent humidity. The monitor may be stored at a maximum humidity of 85 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to Iiyama 60 °C. Minimal were given by Iiyama -20 °C.
Packaging
The monitor is packaged in a cardboard box measuring 48 x 74.5 x 20.4 cm (height x width x depth). The box together with the monitor weighs about 7.5 kg.
