How to find out the manufacturer of the display in a xiaomi smartphone. How can I find out the detailed technical specifications of my smartphone? Looking for scratches, dents and chips on your smartphone
User question...
Good afternoon.
Please help, I want to buy a monitor exactly the same as the one I have now, but I don’t know its exact model. All that is there is a sticker on the body of the device, which only indicates its brand (Samsung).
How can I find out the model of my monitor without disassembling it and taking it to a specialist shop (and is this possible)?
Hello.
There are several ways to determine your monitor model and they are all quite simple. And, by the way, I should note that the monitor model is sometimes needed not only in cases when you want to replace it, but also in order to know its capabilities and acceptable operating modes.
Let's look at a few ways below...
Determining your monitor model
Method number 1: sticker on the body
The simplest and quick way To determine what kind of monitor you have, look for the sticker on the device case. If there is no sticker or inscription on the front side, then in most cases there is one on the back of the device, next to the VGA (D-Sub), HDMI, etc. inputs.
The example below is shown in the photo: monitor model AOC F22s+. Actually, knowing the model of the monitor, you can easily find out all its characteristics on the Internet (on the same Yandex market)...
Method number 2: using special. utilities (Aida, Everest, Astra 32)
Sometimes, there are no stickers on the monitor body (for example, the device could simply come off due to years of use...).
In this case, I recommend using one of the utilities to determine the characteristics of your computer. There are quite a lot of them now, but not everyone can get the maximum information about your monitor. I recommend using Everest or Aida 64 (link to them below).
In the program EVEREST just open the tab "Display/Monitor" , then you will see the following information: monitor name, ID, model, monitor type, serial number, brightness, resolution. aspect ratio, frame rate (scan), etc. In general, everything that was required!
Program AIDA 64 works in the same way: you need to open the same tab "Display/Monitor" : you will see approximately the same information (by the way, the information displayed also depends on the model of your monitor; the screen below shows the properties of the monitor Dell laptop Inspiron 3542 - LG Philips LP156WHB (Dell DCR74)).
The program can show slightly more extensive information ASTRA 32. It has a whole section dedicated to monitors connected to your computer (laptop). By logging into it, you will find out almost all the data about your monitor that can be obtained (probably as much as is in the passport for this product).
ASTRA 32 - monitor: manufacturer, release date, gamma factor, aspect ratio, serial number, monitor ID, display type, input signal, firmware manufacturer, driver status, etc.
Method number 3: in properties (via the Windows Control Panel)
You can also get partial information about the monitor in Windows. To do this, you need to open the control panel at the following address:
This way you will know current resolution (and as much as possible) sweep frequency, monitor model (some information may not be available if you do not have drivers installed for your monitor (not to be confused with video card drivers!)).
That's all I have for this sim, special thanks in advance for any additions.
Good luck identifying the type and model!
Xiaomi smartphones are the best sellers because they are among the best among budget phones. Their characteristics have many more advantages than disadvantages, and analogues from other manufacturers are much more expensive. But there are also unexpected surprises! Here is one of them - these are different screens for identical phones of the Redmi 4 line.
And here we will look at the differences between two identical smartphonesXiaomi Redmi 4 Pro Gray.
We bought them on AliExpress from different sellers. And at first glance they are absolutely the same. Here and there the firmware is stable global 8.1.2.0. But upon closer examination, they turned out to be different!
On the display below, one navigation button turned out to be gray and the other was mirrored. This can be seen in the photo.
As it turns out, different matrices are now installed on Xiaomi Redmi 4 smartphones, from different manufacturers - these are Tianma and EBBG.
How to determine whether Tianma or EBBG is on the phone?
To do this, go to settings and select “about phone”
In the menu that appears, click the bottom button “DEVICE VIEW".
Now the manufacturer and screen version are indicated at the top.
Now it turns out that in the photo on the left is Tianma, and on the right is EBBG.
In this video you can see in full how to determine the manufacturer of the EBBG or Tianma matrix on Xiaomi Redmi 4 Pro:
Upon further testing, I discovered that EBBG does not respond in the “Bright” or “Brilliant” mode.
This is inherent in all screens from this manufacturer and is not considered a technical defect.
Which screen is better EBBG or Tianma? There is no clear answer to this question. Technically they are the same. It's more a matter of taste.
Here are the survey statistics from the 4pda website:
The phone screen resolution is set by the manufacturer itself. Sometimes it does not suit users, for this reason many want to change it. There is no way to change permissions using the gadget settings. Usually you need to get root rights on your smartphone and install some applications.
However, this does not stop many; they do not want to put up with large, inconvenient icons on the screen. For games and ease of use of a smartphone, you need to customize the screen. However, first you should find out the resolution of the device so that, if necessary, you can put the same one back.
How to find out the screen resolution on your phone
Screen resolution is the number of pixels per specific area. The higher this indicator, the better and clearer the image will be. On inexpensive models of phones or tablets, this indicator is usually small. Therefore it is necessary to increase the resolution.
It’s quite easy to find out this indicator; take a screenshot. Depending on the model, the buttons for this function vary, but usually they are “volume” and “lock”. After you take the screen, look at the number of dots in the file information.
How to change screen resolution on Android
You can do this using special applications. One of the popular and easy to use is LCD Density Modder Pro. However, first you need to get root rights, also do backup copy. Because if something goes wrong, you will have to reset the settings. Download the application and open it.
It is worth noting that the utility is English, so it may seem awkward. Android OS must be at least 2.2, so it will fit most modern devices. The application allows you to save and import settings.
How to change screen resolution on Android using a file manager
You need to download any explorer from Google Play. You will also need root rights, otherwise nothing will work. After the application is installed, you need to find the System folder. It should contain a file called "build.prop". Open it with text editor and change the number of dots on the screen, but remember to match the screen capabilities.
After setting the new value, save the file and reboot the gadget. If anything, the previous parameters can be returned back in the same file.
To carry out repairs or purchase new components, you need to know which matrix is installed in the laptop, and which models are suitable for replacement. The easiest way to find out is to disassemble the device, disconnect the matrix and read the markings on it. However, disassembling a laptop yourself is not an easy and dangerous task, so it is better to use one of several other methods. How to find out what matrix is in a laptop?
Methods for determining matrix type
The first and easiest option is to find the necessary information in the documentation for the laptop, if it is preserved. Everything about the main screen parameters will be indicated there: resolution, display diagonal, backlight type, as well as other features. To replace, you need to select a matrix of the appropriate type and size.
However, if the device has been used for a long time, it is most often not possible to determine the type of laptop matrix from documents. In this case, you can use one of several additional methods:
- Download and install on your computer Everest program, another name of this application is AIDA64. You can download it from the link below. Launch the program and go to the “Display” tab. You will see the heading “Monitor Name”, and below it the manufacturer of the matrix and its model will be indicated. Usually this information is already enough to find the necessary spare parts. The same application will help you correctly determine the size of the laptop matrix; the information will indicate the maximum visible area, aspect ratio and maximum resolution.
- Study the label on the laptop itself; very often the manufacturer places on it necessary information. The backlight technology (LED or CCFL) is usually indicated; in addition, the type of matrix, diagonal and resolution are indicated on the label.
- Most reliable way Find out which matrix is suitable for a laptop - get advice from specialists. Call our numbers, and our employees will name the type of matrix that suits all the parameters of your laptop model, and will also help you choose the most profitable option in terms of cost and characteristics. Our catalog always contains matrices for repairing laptops from Dell, HP and other popular brands.
Main types of laptop matrices
To figure out which matrix is on the laptop, it is important to be able to read the manufacturer’s markings. It is not always necessary to replace the matrix with an original part from the same manufacturer; most often you can choose a compatible analogue with the same dimensions and technical parameters.
Most common modern types matrices are designated by the following abbreviations:
- TN+Film is the most common option; these are the matrices that are installed on budget laptops. They have small viewing angles, and if dead pixels appear on the screen, they appear as bright dots.
- MVA matrices have a larger viewing angle and improved color rendering, as well as increased image contrast. A characteristic sign is that a dead pixel looks like a black dot.
- IPS matrices. They have a viewing angle of 180 degrees, and the image is practically not distorted. Dead pixels look like black dots, a working matrix has a high image contrast.
In all cases, the best answer to the question of how to determine the laptop matrix model is to contact service center. This is one of the most expensive parts, so when choosing, you must first understand all the parameters.
Let's assume that you bought a smartphone or tablet from a stranger, and not in an official store. Or you simply ordered a smartphone from an online store and are not sure about the authenticity of its specifications or whether it belongs to a particular brand.
To check whether you have been deceived, you need to use special software that will determine almost everything technical specifications gadget and display its parameters on the screen for your reference.
This is exactly what the application is designed for. СPU-Z from the developer of CPUID.
In this article we will tell you how to determine the exact technical characteristics of an Android smartphone or tablet. And let's review the CPU-Z program.
So, having installed the program from the Goole Play app store and launched it, we will see the following information, divided into several sections:
This is a screenshot of the first bookmark "SOC".
All information about the processor of your device is displayed here. You can find the processor model, number of cores, architecture, process chip manufacturing, clock frequency, load of each core, manufacturer, type graphics accelerator and its frequency, as well as the load level of the chip.
The next tab is called "System" and has the relevant information:
Here you can find out the model of your gadget, manufacturer, brand owner, code name, build number, bootloader modification, version operating system, task execution environment, OpenGL version, screen size, resolution, pixel density, volume RAM.
Amount of used RAM, volume internal memory and her free space. The presence of root access is also displayed.
The third tab is called "Battery" and offers to find out the battery status and its characteristics:
The first line displays the “health” of the battery, then you can see its charge, power from..., status (charging or discharging), manufacturing technology, temperature, voltage and capacity.
The fourth tab is called "Ternal":
Eleven temperature values are displayed here for the parameters tsens_tz_sensor (from 0 to 10) and two values pm8921_tz and pm8821_tz.
The penultimate tab of the CPU-Z program is called "Sensors":
You can find out the indicators of such sensors as an accelerometer, magnetometer, orientation, light sensor, gyroscope, barometer, G-sensor, etc. In short, the data of all the sensors and sensors with which your smartphone or tablet is stuffed.
Last tab "About":
It carries virtually no information load and provides general information about the program. Here you can find the application settings and read the FAQ about it.
