Within this article we will take a closer look at the technical specifications of the 27BK85U monitor from LG. 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 ( 68.4 cm on the diagonal) large and should thus offer enough space for all contents according to LG. 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. 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 89.2 % 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 IPS 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 350 nt. Above all, bright environments are a challenge for monitors. The brightness of the monitor is crucial for an accurate and color-true reproduction of the image to outshine the ambient light. The panel of the 27BK85U shines with a brightness of 450 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 27BK85U 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 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.
HDR
The monitor supports all HDR modes listed here:
- HDR 10
screen design
For the installation of the monitor, a space requirement of approximately 36.5 cm in height, 61.2 cm in width and 4.5 cm in depth is to be assumed.
If you want to place the monitor described here on the desk without a wall mount, you should allow for 45.6 x 61.2 x 23.1 cm (HxWxD) of space. If you want to place the monitor on a table or even transport it, you should expect a weight of 6.2 kg with the stand screwed in. According to LG , you can expect a weight of about 4.6 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 11 cm. This value is always measured from the bottom edge of the screen.
Rotate, tilt and swivel
The monitor from LG 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. The monitor 27BK85U can be tilted. The angle of inclination to the rear is 20. The monitor can be tilted forward by 5 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 27BK85U with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
- 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.
WiFi / Bluetooth
Power consumption
The average consumption figure for 27BK85U is 32 w. The maximum power consumption (peak) specified for this monitor is 50 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
The maximum permissible ambient temperature is 35 °C during operation. Below a temperature of 5 °C , the monitor from LG should again not be used. The humidity must not exceed 85 percent. At least, however, 10 percent humidity.
