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 XUB2790HS-2 from Iiyama.
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. 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. Besides the aspect ratios and the specified screen diagonal, the ratio between the monitor surface and the actual display is probably also relevant for some enthusiasts. This is the general ratio of non-display to display. In other words, 87.3 % of the monitor's front area consists of the display. The remaining percent consists of screen edges and cannot display an image. If you want to place several monitors next to each other, you should make sure that the edges are as small as possible. The display is a AH 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 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 ProLite XUB2790HS-2 30 khz to 80 khz. Vertically, however, the image renews at a minimum rate of 56 hz up to 75 hz. The analog refresh rate of this monitor is 24 khz to 80 khz. The frame rate in the analogue range is vertical at the ProLite XUB2790HS-2 56 hz to 75 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 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 5000000 : 1 of dynamic contrast ratio for the monitor ProLite XUB2790HS-2 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 36.9 cm in height, 62.2 cm in width and 4.5 cm in depth is to be assumed.
The size of the ProLite XUB2790HS-2 on the desk is likely to be particularly relevant for most users. Iiyama specifies a space requirement of 43.3 x 62.2 x 23 cm (HxWxD) with the included stand. The device weighs in total (i.e. also measured with the stand) 6.5 kg. According to Iiyama , you can expect a weight of about 4.25 kg without the stand. 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 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 0 degree. To the right, the monitor can be rotated by 90 degree. The ProLite XUB2790HS-2 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. The tilt of the monitor ProLite XUB2790HS-2 can be individually adjusted to optimize the viewing angle and increase comfort during use. The angle of inclination to the rear is 20. The monitor can be tilted forward by 4 degree.
Ports
The monitor can be connected via 1 VGA 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
"Overdrive" is a feature of the ProLite XUB2790HS-2 , which improves the response time of the pixels to reduce motion blur. This involves increasing the voltage of the pixels to make them switch more quickly between color values. This allows fast-moving images and videos to be displayed more clearly and smoothly. However, too high an overdrive setting, even on this model from Iiyama , can lead to so-called "ghosting", where a shadow image of the previous image is visible on the current image. It is therefore important to configure the overdrive settings appropriately depending on the monitor and application.
WiFi / Bluetooth
Power consumption
The average consumption was given by Iiyama as 27 w. The maximum power consumption (peak) specified for this monitor is 55 w. In standby mode, the device consumes approximately 0.5 w. ProLite XUB2790HS-2 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
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.
