Every caring mother strives to provide her baby with everything, as it seems to her...
LG computer monitors occupy leading positions in the sales rankings. Most customers choose the products of this particular company because they are of high quality, reliability and versatility.
Characteristics
LG monitors come in two types: LCD and Led. Both options have certain advantages and disadvantages. Thus, LCD monitors have greater expansion compared to Led, but they are difficult to maintain. The fact is that any touch will leave fingerprints on the screen, which will be quite difficult to remove.
LG LCD monitors with a diagonal of 21.5-27 inches are based on an IPS matrix, which allows maintaining a constant color temperature. As a result, all colors are reproduced as clearly and efficiently as possible. Thanks to the Full HD extension, the image display is also very clear from any angle. In addition, the use of IPS technology has made it possible to ensure that users do not get tired of their eyes while working at the computer. Also, the company's monitors are multifunctional. For example, the Dual Smart Solution function allows you to configure work with a second monitor, which will greatly facilitate your work.
How to configure?
If your LG monitor does not turn on, then it most likely needs to be adjusted. This process is carried out in two main ways depending on the type of operating system. Let's look at each of them:
Installing or updating drivers
To configure the video subsystem, you may need to install the monitor's native driver (or at least the correct one) on your computer. Although in fact the monitor functions quite normally without additional drivers, in this case it does not work at its full potential. The presence of a driver is mandatory if the user plans to play any computer games.
A driver for an LG monitor is just an information file containing data about the additional capabilities of the device. During its installation (via disk or after downloading from the Internet), the same data is transferred to the Windows registry, and only after that it is used by the video card driver. In this case, the user’s task is to notify the video card about what capabilities the monitor can do. After all, in the future, the video card may set parameters that the device cannot handle, which will lead to its failure.
You can configure the driver for your LG monitor using the “Advanced” button on the tab. After clicking on it, the “Dialog Box Settings” tab appears, in which you can configure the screen properties.
What to do if the computer turns on but the monitor does not work?
The picture on the computer screen may disappear not only because the device does not work. The video signal conversion system itself can lead to this. Thus, problems with no video signal can appear as a result of various monitor malfunctions, video card failure, motherboard failure, incorrect driver installation, and the like.
If the processor turns on, but there is still no image on the screen, then you must check whether the Pover button on the monitor itself is pressed. After this, you should check whether all cables are connected correctly. If this does not work, then you should take the monitor (preferably the processor as well, since the video card could break) to a specialist. Repairing LG monitors usually does not take much time. However, this depends on how quickly the cause of the problem is determined.
Causes of monitor problems
There are several reasons why the monitor does not turn on:
Basic problems
If LG monitors show signs of life when turned on, but after that there are warning messages about the absence of a video signal, then the following malfunctions are possible:
- The video signal cable is burnt or defective. As a result, the monitor does not turn on, but the system unit continues to function normally.
- The monitor does not turn on, while two video cards are mounted in the system unit at once, and only one of them works. You need to try connecting the screen to the connector of another video card. Perhaps the first one failed.
- There is no image on the screen, which was a result of a video card malfunction. To check the functionality of the device, it must be connected to the working unit.
- LG monitors may not work if the computer motherboard is broken. In this case, no signals appear when they are connected.
- The processor may also not turn on. It is advisable to connect the monitor to a work computer and check its functioning. If after such manipulations there is no reaction, repairs may be needed. You can do it yourself, but it is better to entrust the work to a specialist.
Device repair
Without special skills, it is better not to start diagnosing, much less repairing a computer. Repairing LG monitors is a process that is best left to professionals. However, you can try to do it yourself.
First of all, the monitor is disassembled. If you do not know how to disassemble an LG monitor, then you can look at the picture below, which clearly depicts this process.
Using a screwdriver, you need to unscrew the screw that secures the bottom of the stand. After this, you should remove all the fasteners that hold the base of the stand, and then remove it too. Now a flat-tip screwdriver will come in handy. Use it to pry off the front panel of the monitor, and then begin to separate it with careful movements.
If the contents of the screen are attached to the back panel with tape, then you need to peel it off, and then remove the matrix. Now you should disconnect all the contacts that secure the cathode backlight lamps to the inverter circuit. To do this, you must remove the protective cover, under which the corresponding connectors are located. They need to be disconnected. Here it is necessary to replace non-functioning connectors. Once the process is complete, you should reassemble everything in reverse order. How to disassemble an LG flatron monitor? Almost the same as any other LG monitor, but some difficulties may arise during operation.
Analysis of the LG flatron monitor
If the question arises: “how to disassemble an LG flatron monitor?”, then in this case you need to seek help from the instructions described above. However, its repair is carried out a little differently:
- Remove the monitor power board.
- The main problems with such a device may be: disconnected contacts or swollen capacitors. 1000 microfarad capacitors are used here.
- They are replaced by soldering. Old capacitors should be carefully removed. Solder new ones to the places where they were previously soldered.
- Place the board back into the computer monitor.
Monitor circuits
For the LCD panel of a device to function properly, the light source is of paramount importance. The luminous flux in the monitor is created using cold cathode lamps. You can find them on the edges of the monitor. To connect lamps in LCD monitors, you may need a capacitive LG monitor circuit. The inverter creates all the necessary conditions for a controlled glow discharge. In this case, the operating point of each lamp is on the flat part of the curve. As a result, the constancy of their glow over a long period of time becomes possible.
The block diagram of the LG flatron monitor allows you to influence the operation of the standby unit. It takes enough time for the monitor to turn on. As a result, the inverter turns on approximately 2-3 seconds after the screen enters operating mode.
LG IPS235V | Introduction
With a relatively uniform backlight of the screen, there were no gradient stripes, overexposure or special darkening either in the center or in the corners. The notorious effect, known as IPS Glow, which manifests itself in the coloring of a black screen when looking at it at an angle, is quite pronounced, but you have to put up with this in a budget version of the IPS matrix.
As for viewing angles, when looking from the left and right of the monitor LG IPS235V the picture remains virtually unchanged up to the limit of visibility. Vertical angles are also great, but when viewed from above and below we found some impact of the same IPS Glow effect and a certain drop in color accuracy. Contrast measurements showed a value of 650:1, which is not bad for an inexpensive monitor. The brightness of the matrix is average, with a fairly wide range of changes.
In general, the picture on the monitor LG IPS235V It has soft natural colors, smooth color transitions, and good detail in both light and dark parts of the images.
In dynamic scenes in games and films, we did not notice any noticeable trails or afterglows. Note, in addition, the ability to change the monitor resolution when the signal resolution changes - this is especially important in games. We launched games that had the ability to enable low screen resolution in the settings, and we launched them in different resolutions, and every time the monitor LG IPS235V correctly processed the signal, adjusting the image to the screen format - without artifacts or unpleasant ripples.
LG IPS235V | conclusions
Monitor LG IPS235V turned out to be quite an interesting solution that can be “suitable” both in the office and at home. Excellent color rendition and large viewing angles allow the LG IPS235V to become, first of all, a monitor for working with graphics, a tool for photography and video editing enthusiasts, or even a budget option for professional designers and artists, only after a little adjustment. The monitor is quite suitable for watching home videos and simple games.

Some limitations, of course, are imposed by the ability to adjust the stand with a slight tilt forward and backward, and the impossibility of height adjustment. Also, some may find the design overly conservative LG IPS235V. However, the editors found this model quite attractive and appropriate on the user’s desk, especially considering the low price of the monitor.
Advantages:
- Affordable price;
- Good color rendering;
- Low energy consumption;
- Possibility of fine tuning.
Flaws:
- Small possibilities of adjusting the stand;

LG is one of the largest electronics manufacturers and is widely known for its innovation. One of the largest divisions is the LG Displays brand, which accounts for almost a quarter of the global screen market. Since its founding, the company has managed to release many technological innovations, implementing the most modern developments in them. However, the most significant milestone in its history was the introduction of IPS technology, which significantly increased the viewing angle and enlivened the color gamut of displays. At the moment, LG is one of a large number of manufacturers that use and improve this technology in their products, which allows them to create screens with excellent pictures and color reproduction.
In this review we will look at one of the most interesting monitors - LG 34UM58. This is a large widescreen display that is perfect for any task, including gaming, thanks to a number of built-in functions. Let's talk about it a little more.
Design and equipment of the LG 34UM58 monitor
The device has an impressive, monolithic body mounted on a stand, which, by the way, is removable and has a tilt range from -5 to 20 degrees. There are very thin bezels around the display, which further enhances the impression of its size and 21:9 aspect ratio. Dimensions without stand are 829.9 x 48.5 x 374.2 millimeters. With the stand they are 829.9 x 213.2 x 460.7 millimeters. The weight of the LG 34UM58 monitor with and without a stand is 6.8 and 6.3 kg, respectively. This is a more than standard “weight category” for wide-format monitors, which will not cause any particular difficulties during operation. In addition, the device is available in several diagonals, namely 34 inches (Default), as well as 29 and 25 inches.
The rear panel has connectors for VESA 100x100 wall mounting. This is a big plus, since many people prefer to mount screens of this size on the wall rather than installing them on a stand. All the necessary connectors for connection are located here, as well as a small LG logo. In general, the design of the device is distinguished by modern, smooth lines and ergonomics inherent in all products of this brand.
The LG 34UM58 monitor includes the following items:
- power cable;
- HDMI cable;
- fittings for wall mounting VESA 100x100;
- instruction manual and warranty.
Monitor LG 34UM58 - display characteristics

Pros and cons, price of LG 34UM58 monitor
At a fairly affordable price, the LG 34UM58 monitor demonstrates the following impressive advantages:
- Aspect ratio 21:9- This is perhaps the only compelling argument in favor of the device. For those who want to try working with a device in this resolution, but cannot afford to pay a certain amount for a high-quality display, this is an excellent choice.
- Good picture quality (subject to proper calibration). The manufacturer indicates that the device is already sold with optimal factory calibration, but this is not entirely true.
- More or less uniform illumination. During testing, some areas stood out, but weakly.
- Wide range of customization options. In principle, there is enough functionality for a budget model.
- Convenient wall mount, which allows you to use the monitor in a way that is convenient for the user.
- Safety and environmental friendliness.
The price of LG 34UM58 in Russia is about 26,290 rubles.
The device is perfect for those who do not want to pay dearly for new technologies, but are still interested in them. If you compare the monitor with flagship models, then of course it has many shortcomings. But if we take the average for comparison, then the LG 34UM58 is a clear winner due to its wide functionality, image quality and 21:9 ratio.
LG monitors are among the top five most popular products in this category. They differ from screens of other brands in the range of characteristics, as well as in the fact that they quickly implement new developments. Thanks to this, the buyer within the brand can choose both classic models with standard characteristics and purchase a new product.
When purchasing a screen, most buyers are guided by those characteristics that are positioned by almost all brands in advertising campaigns - diagonal, display resolution and matrix type. During use, a lot of nuances appear. And it turns out that it was necessary to take into account the presence of ports, their number and screen coverage.
Audio ports. Not all models have a headphone output. If someone else lives in the room with you and you are going to play games, then this criterion is worth paying attention to. Typical for LG 27UD58-B and 24MP59G-P monitors. It is much more convenient to connect headphones to the monitor than to the system unit, which is located somewhere below - no need to worry about the length of the wire.
Built-in speakers. Their presence on the LG monitor will save space on the computer desk. Presented in LG 29UM69G-B and 27UD69P-W screens. The LG 29UM69G-B model has a matrix with a response time of 1 ms, supports AMD FREESYNC technology, and also knows firsthand about the dynamic synchronization mode and black stabilization. 
Pivot- a screen function that allows you to rotate it horizontally and vertically. Its presence is important for those who work professionally in graphic editors and are engaged in drawing. If you need a monitor for work, think about the relevance of this function and take a closer look at the LG 27UD88-W and LG 24GM79G-B models.
Curved screen. Buying such a monitor makes sense in one case - the user needs a feeling of complete immersion in what is happening. And the larger the diagonal, the better the quality of the picture. The diagonal of such monitors in the LG line is 29-34 inches, models LG 34UC79G-B and 29UM59-P.
Screen coating- it is also important to decide on it at the beginning. Matte does not reflect sunlight, but users with good eyesight see some grain in the image. This is the norm - a “crystalline” effect. Recently, glossy surfaces have been covered with anti-reflective film. The image quality on gloss is better. But you also need to take care of it more carefully than matte.
Fortunately, there are different models in the LG monitor lines. Therefore, it is easy to find a product with the desired characteristics and not deny yourself the pleasure of purchasing equipment from your favorite brand.
LG is a popular South Korean brand that produces electronics with advanced technical characteristics, in some cases second only to Samsung. The main advantages of monitors from this manufacturer can be considered:
- affordability in terms of price and absence of shortages on the market in all price segments;
- stunning color reproduction with optimal contrast and image clarity;
- the now minimal resolution of 1920x1080 pixels;
- the presence of wall mounts in almost all models;
- long service life.
We have selected for you the top 5 best monitors from LG, based on technical specifications, ratings and customer reviews.
TOP 5 best LG monitors
5 LG 24MK430H
The most budget
Country: China
Average price: 8520 rub.
Rating (2019): 4.3
For the budget segment, LG released the 24MK430H at a price of 8,500 rubles. The IPS matrix provides the monitor with saturated colors, which sometimes creates a feeling of unnaturalness, but this is nitpicking. There are no built-in speakers here, but the control is carried out not by buttons, but by a joystick. The HDMI connector allows you to connect all modern video cards, and the cable itself is already included in the package. You can't even turn the leg 90 degrees.
Many settings + high-quality matrix + 75 hertz screen refresh made the model one of the most attractive on the market. If we talk about the design, the model is made in a simple, laconic style without any frills. A small flaw is the stand leg that wobbles under strong pressure. When turned on from the factory, the default settings are very straining on the eyes, so we recommend that you immediately calibrate the monitor upon purchase.
4 LG 22MP58VQ
Compact monitor
Country: China
Average price: 7620 rub.
Rating (2019): 4.4
The 21.5-inch monitor is one of LG's most compact and inexpensive devices, and also boasts good quality. A stylish matte LED screen with continuous illumination, also known as Flicker-Free backlight, does not tire the eyes and helps to better convey all shades of the image. Full high resolution Full HD, rare for miniature models, is successfully complemented by an excellent viewing angle. Thanks to the fast 5ms pixel response, high quality is maintained even in dynamic scenes in movies and games.
Unlike cheaper models, this LG is equipped with three connectors for connecting to a computer and a headphone output. The monitor also supports VGA, DVI and HDMI interfaces, providing reception of analog video, digital video and high-definition television. However, the model also has a small, but not critical, disadvantage - the plastic frame of the monitor is too wide.
3 LG 25UM58
The optimum ratio of price and quality
Country: China
Average price: 10,000 rub.
Rating (2019): 4.5
The considerably cheaper 25UM58 takes 3rd place in our rating. The manufacturer positions it as a budget solution for professional work with graphics. The 25-inch diagonal will delight the buyer with excellent color rendition and clarity, and the resolution of 2560x1080 pixels will make it convenient to work with any graphic objects.
The thin, tight-fitting frame looks elegant and gives the monitor a special chic. The presence of two inputs for connecting to a computer and a headphone jack is an undeniable advantage. This LG also comes with a proprietary wall mount. Therefore, you can not only put it on the table, but also hang it on the wall. The 21:9 aspect ratio allows you to comfortably use the monitor as a TV. Moreover, the device is equipped with two HDMI interfaces, so you can connect two video signal sources to it at once, for example, a computer and an HD DVD player.
2 LG 34UC79G
Top-end monitor with curved screen
Country: China
Average price: RUB 38,989.
Rating (2019): 4.8
The second line of the review is occupied by one of the most innovative monitors with a stylish curved 34-inch diagonal screen. Thanks to the high resolution, screen brightness of 300 cd/m2 and frame refresh rate of 144 Hz, the model is distinguished by unique detail and color reproduction. The 5,000,000 dynamic contrast ratio monitor ensures comfortable gaming or movie viewing even during very bright or dark scenes. The model also has color calibration for those who like to manually adjust color rendition.
At the same time, LG's latest development supports connecting two video sources at once and is equipped with a DisplayPort input, stereo audio, a headphone jack and even two USBs. The picture-in-picture function allows you to simultaneously display video from two different external sources on the monitor. The model is also practical thanks to the ability to adjust the height of the screen and a special mount for installation on a bracket.
1 LG 27GK750F
Best gaming monitor
Country: China
Average price: RUB 29,078.
Rating (2019): 4.9
Here is the best monitor from LG, combining reasonable price for its price segment, workmanship and characteristics. Despite the not-so-large screen diagonal of 27 inches with a resolution of 1920x1080 pixels, the TN matrix is designed just fine. The response time is only 1 ms, and the refresh rate is a record 240 Hz, which is the best in the world. In games, “stuttering” during sudden movements will immediately disappear thanks to FreeSync technology. To distinguish the pixels on the screen you will have to literally lean your nose against the screen.
There is also an excellent alternative to the stock hardware settings, namely “On Screen Control”, through which you can calibrate the monitor. Customers are also pleased with the lightness - despite the significant dimensions, the weight of 6 kg is more than comfortable for transportation. The small width will have a positive effect when mounting the monitor to the wall, which is why the screen will actually merge with it. To prevent the power cable from lying under your feet, a bracket is provided.
How to choose a monitor from LG?
Choosing a monitor is a simple, but important matter, since this particular peripheral is taken on average for 5-10 years, or even more. The recommendations described below apply not only to the LG brand, but also to all other manufacturers.
Monitors whose price starts from 4,000 rubles can be immediately bypassed, since VGA ports are no longer compatible with modern video cards and you will have to buy an adapter.
It is worth rejecting models with resolutions of 1366x768 and 1600x800, since they do not meet modern requirements and 1920x1080 is already considered the required minimum.
It is better not to buy monitors with a screen diagonal of 18.5 inches, as poor color reproduction and low refresh rate will negatively affect the gameplay or just watching a movie. 21.5 inches is now optimal.
