Today we will look at the monitor 27UK650 from LG from the year 2018. 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
27 inches ( 68.4 cm on the diagonal) offer sufficient space for texts in any office applications, for example. As already known, two monitors with different outer dimensions can have the same screen diagonal. In the case of the monitor 27UK650 , we find an aspect ratio of 1.778 to 1. This means that for every 1 pixels in height, 1.778 pixels in width are added. For comparison: A classic CRT monitor had an aspect ratio of 4:3. 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, 89.7 % 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 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. The monitor's panel has a maximum brightness of 450 nt. A high peak brightness enables a particularly clear and well visible display of content on the screen. 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 27UK650 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 27UK650 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:
- HDR 10
screen design
For the installation of the monitor, a space requirement of approximately 36.4 cm in height, 61.3 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 56.7 x 61.3 x 23 cm (HxWxD) of space. The device weighs in total (i.e. also measured with the stand) 6.2 kg. A wall mount should be designed for at least 4.6 kg to hold the 27UK650 neatly and securely. 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 0 degree. To the right, the monitor can be rotated by 90 degree. It is possible to adjust the tilt angle of the monitor 27UK650 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 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 27UK650 with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
- The display/monitor supports Frame Rate Compensation.
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 LG offers a technology to reduce the blue content in its monitor 27UK650. 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.

Power consumption
The average consumption was given by LG as 32 w. The maximum power consumption (peak) specified for this monitor is 45 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
For temperature, the maximum permissible ambient temperature is 40 °C. 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.
