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 27UD58 from LG.
Display
The monitor belongs to the device class 27 inches ( 68.4 cm on the diagonal). Let's keep it short and sweet. The monitor has an aspect ratio of 1.778 : 1. Approximately 84.1 % of the front surface of the monitor is taken up by the display, while the remaining part is screen edges that do not allow the image to be displayed. If you want to place several monitors next to each other, it is advisable to choose models with narrow edges. The display is a AH panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 163 ppi. The pixel pitch is 0.155 mm. The continuous possible brightness specified by the manufacturer LG 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. LG promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the 27UD58 30 khz to 135 khz. Vertically, however, the image renews at a minimum rate of 56 hz up to 61 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 SRGB color space is 99 %.
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 LG 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 27UD58 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 a possible wall mounting or comparison to the currently owned monitor at the beginning, the dimensions of the monitor without stand/feet: 37.6 cm x 63.3 cm x 6.1 cm (HxWxD)
The size of the monitor (stand included) is 46.4 x 63.3 x 20.2 cm (HxWxD). The device weighs 5.6 kg with the stand in place. According to LG , you can expect a weight of about 5 kg without the stand. 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 LG cannot be rotated. 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 27UD58 according to personal preference to ensure ergonomic and comfortable viewing. The angle of inclination to the rear is 15. The monitor can be tilted forward by 2 degree.

Features
- Flicker Free: LG '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 27UD58 with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
- Picture by Picture mode
- The display/monitor supports Frame Rate Compensation.
The monitor from LG 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.
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 LG 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 BOE and has the model number MV270QUM-N10.
WiFi / Bluetooth
Power consumption
The average consumption figure for 27UD58 is 29.5 w. The maximum power consumption (peak) specified for this monitor is 37 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. 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
During operation, the ambient temperature must not exceed 40 °C , to ensure full functionality. Below a temperature of 0 °C , the monitor from LG 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 LG 60 °C. Minimal were given by LG -20 °C.
Packaging
The monitor is packaged in a cardboard box measuring 45 x 71 x 13.9 cm (height x width x depth). The box together with the monitor weighs about 7.2 kg.
