Within this article we will take a closer look at the technical specifications of the 34UM88 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 actual display. This information is given in inches and measures the screen diagonal of the display. It can happen that displays with the same size specification have different dimensions, since square monitors, for example, can belong to the same category as a widescreen monitor. The monitor from LG in this article has a size of 34 inches ( 86.3 cm on the diagonal). While classic CRT monitors were built with a screen ratio of 4:3, this monitor has a ratio of 2.389 : 1 (width to height). Approximately 84.9 % of the front surface of the monitor is taken up by the display, while the remaining part is screen edges that do not allow the image to be displayed. If you want to place several monitors next to each other, it is advisable to choose models with narrow edges. The display is a IPS panel. The panel has a resolution of 3440 x 1440 px. The pixel density is 109 ppi. The pixel pitch is 0.233 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 34UM88 30 khz to 90 khz. Vertically, however, the image renews at a minimum rate of 40 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. The coverage of the Adobe RGB 1998 color space is 80 % according to the manufacturer. 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 34UM88 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
Without the stand, the monitor comes with a width of 82.9 cm , a height of 37.9 cm and about 4.9 cm.
The size of the 34UM88 on the desk is likely to be particularly relevant for most users. LG specifies a space requirement of 42.8 x 82.9 x 25.2 cm (HxWxD) with the included stand. As for the weight, LG states a total weight of 8.4 kg with stand. The monitor 34UM88 without the stand weighs 6.3 kg. This weight reduction should be taken into account for wall or arm mounting, since monitor arms have a maximum load capacity. 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 12 cm. This value is always measured from the bottom edge of the screen.
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 tilt of the monitor 34UM88 can be individually adjusted to optimize the viewing angle and increase comfort during use. The angle of inclination to the rear is 20. 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 7 w power.
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 34UM88 with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
- Picture by Picture mode
- Picture in Picture mode
- 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.
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 LM340UW1-SSA2.
WiFi / Bluetooth
Power consumption
The average consumption figure for 34UM88 is 56.7 w. The maximum power consumption (peak) specified for this monitor is 70 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. In ECO mode, the monitor consumes 23 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 5.6 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 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.
