Within this article we will take a closer look at the technical specifications of the 31MU97 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
Any multimedia content can be displayed on 31 inches ( 78.7 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 31MU97 , we find an aspect ratio of 1.896 to 1. This means that for every 1 pixels in height, 1.896 pixels in width are added. For comparison: A classic CRT monitor had an aspect ratio of 4:3. Approximately 85.8 % of the front surface of the monitor is covered by the display, while the remaining area consists of screen edges that do not allow any image output. If you want to set up several monitors next to each other, it is advisable to prefer models with the narrowest possible edges. The display is a AH panel. The panel has a resolution of 4096 x 2160 px. The pixel density is 148 ppi. The pixel pitch is 0.17 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. The refresh rate is horizontally seen at the 31MU97 30 khz to 135 khz. Vertically, however, the image renews at a minimum rate of 56 hz up to 61 hz. 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. The coverage of the Adobe RGB 1998 color space is 99 % according to the manufacturer. According to the manufacturer, the coverage of the DCI-P3 color space is 97 %. According to the manufacturer, the coverage of the SRGB color space is 100 %.
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 1000000 : 1 of dynamic contrast ratio for the monitor 31MU97 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
The monitor has a width of 73.6 cm without its attached stand/stand. The height is dimensioned at about 40.7 cm , while the for the depth of the monitor should be kept free at about 5.2 cm.
The size of the monitor (stand included) is 48.3 x 73.6 x 24.1 cm (HxWxD). If you want to place the monitor on a table or even transport it, you should expect a weight of 9.6 kg with the stand screwed in. According to LG , you can expect a weight of about 7.7 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 14 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 monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. The tilt of the monitor 31MU97 can be individually adjusted to optimize the viewing angle and increase comfort during use. The angle of inclination to the rear is 15. The monitor can be tilted forward by 5 degree.
Ports
camera
This monitor does not have a camera.
Loudspeaker
The monitor from LG has integrated speakers, for playing sounds, music or speech. The sound is emitted via 2 speakers, which are integrated into the device. Each of the built-in speakers has a contingent of 5 w power.
Features
- Flicker Free: LG 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- Picture by Picture mode
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 LG Display and has the model number LM310UH1-SLA1.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 48 w. The maximum power consumption (peak) specified for this monitor is 85 w. In standby mode, the device consumes approximately 1.2 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 1.4 amps specified. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
For temperature, the maximum permissible ambient temperature is 35 °C. Below a temperature of 10 °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 90 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.
