Display, power consumption, dimensions, technologies used, connections, certifications, comfort features. All these keywords can be relevant for a purchase decision, but an exact comparison is often difficult. For this reason, we will summarize as many of the mentioned specifications as possible in an understandable form in the course of this article. Let's start with the most important component of the ProLite B2791HSU from Iiyama.
Display
The monitor belongs to the device class 27 inches ( 68.5 cm on the diagonal). 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). 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 ProLite B2791HSU is a monitor with a ratio of 88.3 % between usable and non-usable front surface. The display is a TN 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 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 170 ° (horizontal) viewing angle. Iiyama promises stable color reproduction moreover within a 160 ° vertical angle. The refresh rate is horizontally seen at the ProLite B2791HSU 30 khz to 83 khz. Vertically, however, the image renews at a minimum rate of 55 hz up to 75 hz. The minimum response time of the monitor is ms.
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 NTSC 1953 color space is 72 %.
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 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 12000000 : 1 of dynamic contrast ratio for the monitor ProLite B2791HSU 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
The monitor has a width of 61.3 cm without its attached stand/stand. The height is dimensioned at about 37 cm , while the for the depth of the monitor should be kept free at about 5.4 cm.
If you want to place the monitor described here on the desk without a wall mount, you should allow for 39.7 x 61.3 x 23 cm (HxWxD) of space. The device weighs in total (i.e. also measured with the stand) 6.9 kg. 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 cannot be rotated. The ProLite B2791HSU can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 45 degree. Pivoting to the right is possible up to 45 degree. It is possible to adjust the tilt angle of the monitor ProLite B2791HSU according to personal preference to ensure ergonomic and comfortable viewing. The angle of inclination to the rear is 22. The monitor can be tilted forward by 5 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: By dynamically synchronizing the refresh rate of the ProLite B2791HSU with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
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 ProLite B2791HSU.
WiFi / Bluetooth
Power consumption
The average consumption figure for ProLite B2791HSU is 19.7 w. In standby mode, the device consumes approximately 0.5 w. ProLite B2791HSU 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. There are 1.5 amps specified. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
The maximum permissible ambient temperature is 35 °C during operation. 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.
