Today we will look at the monitor 34WN780 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
34 inches ( 68.4 cm on the diagonal) offer sufficient space for texts in any office applications, for example. The size specification of a monitor refers to the screen diagonal, which is usually specified in inches. It is only comparable to a limited extent for different formats. For example, a conventional 4:3 monitor with the same screen diagonal has 6% less width, but 13% more height and a total of 7% more surface area than a monitor in 16:10 format. Despite the difference in working area, wider monitors are better suited for consuming games or current movies, for example. It is also easier to display several documents simultaneously on widescreen monitors. So, it depends on the current use case whether the aspect ratio of 1.778 : 1 makes sense for the intended use case. In addition to the aspect ratios and the specified screen diagonal, some enthusiasts may also be interested in the ratio between the monitor area and the actual display. This refers to the general ratio between the non-display area and the display. In other words, approximately 90.5 % of the front surface of the monitor consists of the display, while the rest is made up of screen edges and cannot display an image. When arranging several monitors next to each other, it is advisable to choose models with the narrowest possible edges. The display is a VA panel. The panel has a resolution of 2560 x 1440 px. The pixel density is 113 ppi. The pixel pitch is 0.233 mm. The continuous possible brightness specified by the manufacturer LG is 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. Vertically, however, the image renews at a minimum rate of 50 hz up to 50 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 8 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. The coverage of the Adobe RGB 1998 color space is 113 % according to the manufacturer. According to the manufacturer, the coverage of the NTSC 1953 color space is 96 %. According to the manufacturer, the coverage of the SRGB color space is 107 %. The REC 2020 color space is covered to 81 %.
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 2500 : 1 , according to the manufacturer.
HDR
The monitor supports all HDR modes listed here:
screen design
LG Specifies the following dimensions for the monitor 34WN780 without stand/feet: 32.5 cm x 57.7 cm x 3.3 cm (HxWxD)
The size of the monitor (stand included) is 35.2 x 60 x 22 cm (HxWxD). If you want to place the monitor on a table or even transport it, you should expect a weight of 10.9 kg with the stand screwed in. Without stand, the monitor weighs 8.2 kg. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 9.5 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. The 34WN780 can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 60 degree. Pivoting to the right is possible up to 60 degree. Thanks to the tilt function of the 34WN780 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 4 degree.
Ports
The ' 34WN780 ' monitor is equipped with 1 RJ45 Ethernet port(s) that allow direct connection to wired networks. This feature opens up the possibility for users to benefit from a stable and potentially higher network speed, especially in situations where a reliable Internet connection is essential.
camera
This monitor does not have a camera.

Features
- Picture by Picture mode
- The display/monitor supports Frame Rate Compensation.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 67 w. In standby mode, the device consumes approximately 0.5 w. 34WN780 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
The monitor has a built-in ambient light sensor, which can be used, for example, to dynamically adjust the brightness of the monitor to the ambient conditions. The maximum height at which the monitor may be operated, according to the manufacturer's specifications, is 5 km. For temperature, the maximum permissible ambient temperature is 35 °C. Below a temperature of 5 °C , the monitor from LG should again not be used. The humidity must not exceed 80 percent. At least, however, 20 percent humidity. The monitor may be stored at a maximum humidity of 85 percent. The minimum humidity during storage should not fall below 10 percent. The maximum storage temperature should be according to LG 60 °C. Minimal were given by LG -10 °c. According to the manufacturer, the monitor may be stored at a maximum height of 12.192 km.
