Today we will look at the monitor 27UD69 from LG from the year 2017. 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
The display is sized at 27 inches ( 68.4 cm on the diagonal). As already known, two monitors with different outer dimensions can have the same screen diagonal. In the case of the monitor 27UD69 , 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. In addition to the aspect ratios and the specified screen diagonal, some enthusiasts may also be interested in the ratio between the monitor surface and the actual display. This ratio describes the general relationship between non-display and display. In other words, approximately 89 % of the front surface of the monitor consists of the display, while the rest consists of screen edges and cannot display an image. When setting up several monitors next to each other, it is advisable to give preference to models with the narrowest possible 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 300 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 27UD69 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 1300 : 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 27UD69 cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio.

The monitor supports all HDR modes listed here:
screen design
The following dimensions must be planned for a free-standing stand without attached feet/stand: 36.5 cm x 61.5 cm x 4.9 cm (HxWxD)
The size of the 27UD69 on the desk is likely to be particularly relevant for most users. LG specifies a space requirement of 45.5 x 61.5 x 20.9 cm (HxWxD) with the included stand. As for the weight, LG states a total weight of 5 kg with stand. A wall mount should be designed for at least 4.6 kg to hold the 27UD69 neatly and securely. 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. The monitor 27UD69 offers the option of adjusting the tilt as required to create an ergonomic working environment and reduce visual fatigue. 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 27UD69 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 was given by LG as 29.8 w. The maximum power consumption (peak) specified for this monitor is 40 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. There are 2 amps specified. 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.
