Today we will look at the monitor U28D590D from Samsung 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
Texts, videos and/or other applications can be displayed on the 28 inches ( 71.1 cm on the diagonal) of the monitor. Television screens and monitors usually have an aspect ratio of 16:9 (approximately 1.78:1). More rarely, computer monitors are also found with an aspect ratio of 16:10.
Ultrawidemonitors are often manufactured with an aspect ratio of 21:9 (approximately 2.34:1). They are mainly used for computer games and as an alternative to two side-by-side screens. The first devices of this type came onto the market around 2014. Against this backdrop, the monitor U28D590D from Samsung faces an aspect ratio of 1.778 : 1. In addition to the aspect ratios and the specified screen diagonal, the ratio between the monitor surface and the actual display could also be relevant for some enthusiasts. This ratio represents the general relationship between non-display and display. In other words: Approximately 78.2 % of the front surface of the monitor consists of the display, while the remaining percent consists of screen edges and is not suitable for image reproduction. If you want to place several monitors next to each other, you should make sure you choose models with the narrowest possible edges. The display is a TN panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 157 ppi. The pixel pitch is 0.16 mm. The continuous possible brightness specified by the manufacturer Samsung is 370 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. Samsung promises stable color reproduction moreover within a 160 ° vertical angle. The refresh rate is horizontally seen at the U28D590D 30 khz to 134 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 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 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 Samsung 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 U28D590D 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 66 cm without its attached stand/stand. The height is dimensioned at about 41 cm , while the for the depth of the monitor should be kept free at about 6.4 cm.
The size of the monitor (stand included) is 48.6 x 66 x 16.9 cm (HxWxD). As for the weight, Samsung states a total weight of 5.65 kg with stand. Without stand, the monitor weighs 5.04 kg. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting.
Rotate, tilt and swivel
The monitor from Samsung 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 U28D590D 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 1 degree.

camera
This monitor does not have a camera.
Loudspeaker
Features
- Flicker Free: Samsung '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
- The display/monitor supports Frame Rate Compensation.
The monitor U28D590D supports upscaling of the input signal up to 4k resolution.
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 Samsung 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 Innolux and has the model number M280DGJ-L30.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 32 w. In standby mode, the device consumes approximately 0.45 w. When switched off, on the other hand, the monitor consumes only 0.3 w. U28D590D 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. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
For temperature, the maximum permissible ambient temperature is 40 °C. Below a temperature of 10 °C , the monitor from Samsung 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 95 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to Samsung 45 °C. Minimal were given by Samsung -20 °C.
Packaging
The monitor is packaged in a cardboard box measuring 45.2 x 79.4 x 10.9 cm (height x width x depth). The box together with the monitor weighs about 7.4 kg.
