Today we will look at the monitor 29UB55 from LG from the year 2014. 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 29 inches ( 73 cm on the diagonal). For books or documents, a portrait format layout is usually used because the reading flow decreases as the width of the text increases. For small diagonals, screens in 4:3 format have a clear advantage because they are better suited for display due to their height. In contrast, widescreen monitors are better suited for playing video games or displaying several documents side by side, for example. Depending on the application, it should be decided individually whether the aspect ratio of 2.37 : 1 is sufficient. 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 82.8 % 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 2560 x 1080 px. The pixel density is 96 ppi. The pixel pitch is 0.263 mm. The continuous possible brightness specified by the manufacturer LG is 250 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 29UB55 30 khz to 90 khz. Vertically, however, the image renews at a minimum rate of 50 hz up to 75 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 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. 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 5000000 : 1 of dynamic contrast ratio for the monitor 29UB55 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
For the installation of the monitor, a space requirement of approximately 32.8 cm in height, 70.3 cm in width and 4.3 cm in depth is to be assumed.
The size of the monitor (stand included) is 37.7 x 70.3 x 25.9 cm (HxWxD). The device weighs 6.3 kg with the stand in place. According to LG , you can expect a weight of about 4.9 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 13 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. It is possible to adjust the tilt angle of the monitor 29UB55 according to personal preference to ensure ergonomic and comfortable viewing. 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 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
- The display/monitor supports Frame Rate Compensation.
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 LM290WW2-SSA1.
WiFi / Bluetooth
Power consumption
The average consumption was given by LG as 34 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 0.5 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 2.4 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 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.
