Screen resolution is a value that determines the number of pixels per unit of area. Screen resolution is expressed in the number of horizontal and vertical pixels, for example, 1280x720. This means that the width in the example is 1280 pixels and the height is 720 pixels.
How to find out the display resolution on your smartphone? There are a lot of ways. The easiest way is to refer to the specification of your device on the manufacturer’s official website, where the necessary information is indicated. It is often indicated on the packaging of the smartphone, although not always. We will show you perhaps the simplest method, for which you only need the smartphone itself.
You take a screenshot of the screen, for which you usually need to press the volume up + Power or volume down + Power keys. If the picture remains on the screen, great, in our example it is saved in the gallery, but not shown on the screen. That's why we open the gallery.
Find the screenshot and tap on it.
At the top of the window, click on the three dots, a menu appears, select “Information”.
We see the width and height - this is the resolution, in our example - 1080x1920 pixels.
However, this method is not always reliable. This is due to the fact that the screen resolution can be changed, so in the above example the current resolution will be indicated. It is also worth pointing out that some manufacturers indicate in the specification the maximum display resolution, which is only available in certain modes.

How to find out the phone screen resolution through settings?
Finding out the phone screen resolution may be necessary when working with certain programs or applications. If they are compatible, then the program will work without any complaints. If the resolution does not meet the requirements, working with the application may be accompanied by errors, image distortion, and so on. In addition, the exact resolution allows you to select the appropriate image, for example, for your desktop background or lock screen.
Not on all mobile devices the screen resolution can be found in the settings. However, you should try this method first, as it is one of the easiest and fastest. For example, on Samsung smartphones this method is guaranteed to work. To find out the screen resolution, the user needs to:
Several values will be available here, one of which is currently activated. This number of dots is the current phone screen resolution. The highest number listed is the maximum phone screen resolution that you can manually select. This is the number that should be used for comparison with the requirements of applications or programs.
Changing display settings without using special programs
You can make the appropriate settings without using applications. All you need is a file manager, for example, ES Explorer, Explorer, ES File Explorer. You can find many convenient and free applications in the Google Play store. Users will have to open root access on their tablet computer or smartphone. This method is only suitable for rooted devices.
Next, you need to find the System folder in the file system of your tablet or smartphone. It will definitely contain the “build.prop” file, which is responsible for the gadget’s resolution settings. It should be opened using any text editor. After this, you should execute the command Operations - Change. As a result, changing the resolution will become available. You should change the numeric value in the line “ro.sf.lcd_density=(digits)”.
After setting new parameters, you should save all changes and restart your mobile device. Such actions will activate new settings. We do not recommend changing the resolution significantly, as this may damage the mobile device and cause incorrect operation.
How to find out screen resolution through the AIDA64 application?
On many smartphones, for example Xiaomi (Redmi), you cannot find out the screen resolution in the settings. To do this, you need to use third-party applications that read information about all indicators of the smartphone (temperature, sensor status, etc.) and provide it to the owner in an understandable form. One such free application is AIDA64. To find out your screen resolution, follow these simple instructions:
First way
It is not suitable for all users: some devices, usually from the flagship segment, allow you to change the screen resolution, in which case it will be indicated in the settings. Let's show an example based on a Samsung smartphone.
Go to the “Display” section.
Find the “Screen Resolution” subsection and open it.
And look at the maximum screen resolution - this is it.
In some cases, the default resolution is not the maximum resolution, as in the example, but that is another question.
MultiTouch Visualizer 2
A simple touch test. Unlike many similar applications, MultiTouch Visualizer 2 clearly intercepts any touch. When the definition areas overlap and the points coincide along the location axis, there are no freezes. Interaction with the sensor takes place on a hardware basis, so you don’t have to look at the artificial limitation - the application reads as many touches as the device’s touchscreen allows. Among the additional functions, MultiTouch Visualizer 2 can determine the distance between two touch points and the length of the zoom pinch. Although the application is not new, it is very reliable, and it is distributed completely free of charge, even without annoying advertising banners.
Pros:
- there is no software limit on the number of touches;
- accuracy and productivity;
- free and without advertising.
Minuses:
- There are no objective disadvantages.
Second way
If your smartphone only uses one resolution, do something different and take a screenshot. We have told you how to do it more than once - an example for a Samsung smartphone.
When the screenshot is taken, go to the gallery.
Tap on the screenshot.
Click on the "Menu" or "Info" button. The latter can be in the form of the letter i; in our example, you need to click on three dots.
And the screen resolution used will appear here:
Just remember that this option is not suitable for photos taken using a smartphone camera - the image may have a completely different resolution.

Screen resolution on Android: why change and how to do it
In advertising of gadgets, they often focus on image quality and constantly forget that it’s not just about the matrix. The coolness of the picture largely depends on what resolution the device display supports. And if everyone knows about setting this parameter on a computer monitor, then for some reason they always forget about the screen resolution on an Android device. Adjusting the screen resolution allows you to optimize the operation of the gadget.
Screen parameters table and recommendations
We present in the table the types of screen resolutions and other interrelated display parameters in smartphones available today.
| Resolution/Density | Diagonal | Price category |
| 480x800 and 480x854 px (WVGA) 160 or 240 dpi | 3.5 - 4 inches | Installed on inexpensive entry-level models |
| 540x960 px (qHD), 160,240 or 320 dpi | 4.5 - 4.8 inches | Used on budget-level models |
| 720x1280 px (HD), 240 or 320 dpi | 4.8-5.5 inches | Mid-price segment of models |
| 1080x1920 – (Full-HD), 320, 480 or 640 dpi | 4.8-7 inches | Flagship model segment |
| 1440x2560 px. (QuadHD), 480 or 640 dpi | 5-7 inches | Newfangled, but rarely seen in 2022, smartphones with a 4K screen. |
When choosing a gadget with a large display (from 5 inches), for good clarity, the matrix parameters should be at least 720x1280 px with a density of 240 dpi. Due to the low pixel density, the picture on a display with a large diagonal and low resolution will be blurry and less clear than on a display with the optimal combination of interrelated characteristics.
How justified the use of 4K displays in smartphones is a controversial issue. With such dimensions, for the human eye the difference with the same Full HD will be practically invisible. In addition, today very few smartphone programs support this picture quality. Therefore, buying a smartphone with a high-resolution screen is more of a fashion statement than a real benefit.
Important! It is known that with 100% vision under ideal conditions, the human eye is able to distinguish points with a density of up to 350 dpi, and then under ideal conditions. For a relatively comfortable perception, values from 250 dpi are sufficient.
It is worth remembering that when turned on, a smartphone’s pixel-dense and high-resolution screen affects the depletion of the battery (recharging is required more often). Therefore, it is recommended to choose a gadget with an optimal screen resolution corresponding to its level of performance, diagonal size and battery capacity. Which smartphone screen resolution is better depends on the buyer’s preferences.
Screen resolution concept
In technical language, display resolution refers to the number of small dots (pixels) that fit on the screen in height and width. Pixels can be square, rectangular or hexagonal in shape.
The main units of measurement for resolution are ppi (pixels per inch), but there are other values: dpi, spi and lpi, which are used in other areas, for example, to determine print quality.
To understand what resolution is in practice, try zooming in on any image as closely as possible. It is best to run this experiment on a PC in some kind of graphics application for drawing, then you are guaranteed to see how the picture breaks up into individual points. The same principle is used when creating an image on a smartphone display, and the greater the number of composite points, the better.
How much PPI do you really need?
It has been found that most people with visual acuity of 10/10 are able to distinguish objects 1 arc minute in size. This stems from the structure of our eye, more precisely, from the number of cones that perceive light.
The closer an object is to the eye, the finer details we can recognize. But only up to a certain limit. Our “optical system” also has limits on how much focal length can be adjusted. The eye has difficulty focusing on objects located closer than 25 cm, and the closer, the worse. At the distance of best vision (250 mm), the linear dimension of one arc minute is
The pixel density value corresponding to this size is 358 PPI. So for most people, higher pixel densities simply don't make sense.
How to find out the screen resolution on an Android device
Manufacturers and sellers of mobile devices often ignore such a parameter as display resolution. It’s easier for them to specify the diagonal, the number of transmitted colors and write something smart in Full HD style. But without simple hard-working pixels, things won’t work, and therefore it’s important to know how to check the screen resolution on Android. You can do this using the following methods.
Standard method - through phone settings
This is the simplest method for determining the screen resolution of a mobile device. Just open the “Settings” menu, go to the “About phone” submenu, where you find the desired item indicating the current value.
Due to the abundance of manufacturers and brands of gadgets, as well as Android firmware versions, many users may not have this item in this submenu. For Android devices, such confusion is quite normal, no need to worry.
Via screenshot
This method is somewhat more complicated, but it is guaranteed to suit all owners of Android mobile devices. You need to take a screenshot of the screen by simultaneously pressing the volume and lock keys. Some devices use a different button combination, but this will not affect the final result.
Then you should open the resulting image through the gallery, find the additional actions item, where you select the “Details” function. The table that opens will display the parameters for the width and height of the image, expressed in pixels. This is the current resolution.
Through installation of a special application
We will tell you more about special applications for controlling screen resolution on smartphones and tablets below.
Using the SecondScreen app
Applications such as Resolution Changer Pro, SecondScreen will help you increase or decrease the resolution. As with the previous methods, root access is required. SecondScreen can:
The advantages of the SecondScreen application include the ability to connect the gadget to the Internet via Bluetooth or Wi-Fi. It can turn off the backlight of the smartphone or tablet screen for searching the Internet after connecting the gadget to the big screen. The touch display will remain active. The SecondScreen app can be installed through the Google Play store. It is free, which will be an additional advantage for many users.
The screen resolution of a tablet or smartphone that runs on the Android operating system does not always meet the requirements of users. In this case, you can change the device settings. There are special applications for this. You can make changes manually using knowledge of the Android shell file system. Difficulties may arise only in obtaining root rights, which are necessary for such actions.

How to change the display resolution on a smartphone/tablet
Changing the resolution is not the same as reducing the screen size on an Android phone. It is possible that after changing the settings, some part of the display will become inactive, but this is due to the fact that the selected parameters do not fit the screen diagonal. It is not the size that changes, but the number of pixels in each inch of the visible area, thus controlling the image quality.
In order not to make a mistake with this setting, you can find a resolution calculator on the Internet, where when entering the dimensions of the monitor, the user receives data in pixels.
Why manipulate display resolution? Typically, these settings are used in the following cases:
Now let's look at how you can change the screen resolution on an Android tablet or smartphone.
LCD Density Modder Pro program
The LCD Density Modder Pro app should not be used by inexperienced mobile device users. It is free and easy to find in app stores or on various websites. A simplified version is available on Google Play, but there you can only view the current and available settings.
To change the screen resolution using LCD Density Modder Pro, you first need to get administrator rights, that is, root. Further work with the program is as simple as possible; you should select a value from the list or enter any value of your choice.
It was not for nothing that Android OS developers limited the rights of device owners, because... rash actions can lead to serious damage, even turning the smartphone into a “brick”. So if you're just interested in experimenting with screen resolution, check out the following program.
SecondScreen program
The name of the application SecondScreen translates as “second screen”. It is freely available on Google Play and does not require administrator rights to operate. When you launch the program, you activate a second home screen, for which you can set the resolution of your choice. The program itself will tell you which parameters are suitable for your device.
Using the LCD Density Modder Pro App
The LCD Density Modder Pro system utility allows you to change the resolution of your smartphone or tablet running on the Android operating system. But it should be noted that the program will only work on gadgets after receiving root rights. We recommend that you back up your files first, as changes you make may lead to unexpected results. If you set an incompatible resolution value, you will have to reset the settings. In this case, only backup saving will help save important information.
The program has an English interface that will be understandable and convenient for most users. After making changes, the display will show more data, which is, of course, the main purpose of the changes. It is very important to set the correct values that will be compatible with the gadget.
Features of the LCD Density Modder Pro program include the ability to save convenient settings to apply them at the right time. You can import, export, delete such parameters. The program is compatible with most modern mobile devices, since successful use requires an Android version of at least 2.2.
How to find out your phone screen resolution
Smartphone screen resolution is usually called the value that determines the number of pixels per unit area. In simple terms, screen resolution is the ratio of the width and height of the smartphone display. Previously, almost all smartphones were produced with standard display resolutions - 1920x1080, 1280x720 pixels, etc. And now a huge variety of smartphone models with different resolutions are produced. In today's article we'll talk about how to determine the screen resolution of your phone device:
Determine screen resolutions online.
On this page you can determine the screen resolution of your monitor in pixels. This can be done very simply and quickly online. At the top you see your current resolution in px (pixels), which was determined automatically. That is, by and large, you just need to come here and get acquainted with the results of the instant determination. If you need to find out the monitor resolution, then our service will help you with this.
How is resolution determined?
All modern browsers have functions that allow you to tell the open site some technical information about the client’s computer. This is required so that sites can be designed taking into account the individual characteristics of various devices. One of these functions is the ability to find out the pixel resolution of the screen. To avoid errors, we have also developed a special algorithm that performs a double permission check. Thus, the diagnostic information on our website has a high degree of reliability. The results of testing on many computers have convincingly shown that the probability of error in the determination is practically zero.
An easy way to find out your screen resolution
Method No. 1 Official website
The easiest way to find out the exact resolution of your smartphone is by visiting the manufacturer's official website. To do this, you need to enter the following phrase into the search bar of any search engine: “LG K8 official website” (instead of “LG K8”, enter the model name of your smartphone). The search engine will display a list of sites, among which the required site will be among the first.
There you can see all the characteristics of your device. Manufacturers also often indicate the screen resolution on the phone packaging or in the instructions for use. If for some reason the instructions and packaging from the smartphone have not been preserved, and there is no desire to visit the manufacturer’s website, then move on to the next method.
Method No. 2 Screenshot
This method is suitable for all smartphone models. Let's look at an example on the LG K8 smartphone:
• Take a screenshot of the screen. On almost all smartphone models, a screenshot is taken by simultaneously pressing two keys at once: the volume down key + the power off button.
• After taking a screenshot, find it in the gallery and call the context menu. Most often, the context menu is called up by long pressing on the image.
• Go to the “Information” section, where resolution indicators will be present.
Unfortunately, this method is not entirely accurate. This is explained by the fact that the screen resolution can be changed in the settings, so in the case of the above example, it will be possible to determine only the resolution that is currently set in the settings. It is also worth noting that on some smartphone models, the maximum screen resolution indicated in the specifications becomes available only under certain conditions.
In conclusion, it is worth mentioning one more method. In some smartphone models, screen resolution settings can be found in the general settings section, which is usually called “Screen” or “Display”.

Where did 2K, 4K, 8K come from?
There are more than 30 different resolution formats, ranging from QVGA 240x320 px to a stunning 10K with a resolution of 10240x5760 px. You can study the most common screen resolutions below.
| Name | Permission | Aspect Ratio |
| HDTV (Full HD) (FHD) 1080p | 1920×1080 | 16:9 |
| WUXGA | 1920×1200 | 16:10 |
| 2K DCI (Cinema 2K) | 2048×1080 | 19:10 |
| QWXGA | 2048×1152 | 16:9 |
| QXGA | 2048×1536 | 4:3 |
| UWHD | 2560×1080 | 64:27 |
| WQXGA (WQHD) (QHD 2K) | 2560×1440 | 16:9 |
| WQXGA | 2560×1600 | 16:10 |
| QSXGA | 2560×2048 | 5:4 |
| WQXGA+ | 3200×1800 | 16:9 |
| WQSXGA | 3200×2048 | 25:16 |
| QUXGA | 3200×2400 | 4:3 |
| Ultra WQHD | 3440×1440 | 21:9 |
| 4K UHD (Ultra HD) | 3840×2160 | 16:9 |
| WQUXGA | 3840×2400 | 16:10 |
| 4K DCI (Cinema 4K) | 4096×2160 | 19:10 |
| 5K/UHD+ | 5120×2880 | 16:9 |
| HSXGA | 5120×4096 | 5:4 |
| WHSXGA | 6400 × 4096 | 25:16 |
| HUGA | 6400 × 4800 | 4:3 |
| 8K UHD (UHDTV-2X) | 7680 × 4320 | 16:9 |
| WHUXGA | 7680 × 4800 | 16:10 |
| 10K | 10240 × 5760 | 16:9 |
| 12K | 11520 × 6480 | 16:9 |
Attentive readers will have noticed that there are a couple of different lines in the table with 2K designations. The situation is similar with 4K resolution. In fact, there are several different resolutions for the 4K format:
| Academic 4K | 3656 × 2664 | 1,37:1 |
| Casketed 4K | 3996 × 2160 | 1.85:1 (Flat) |
| Full frame 4K | 4096 × 3072 | 1,33:1 (4:3, 12:9) |
| Widescreen 4K | 4096 × 1716 | 2.39:1 (Scope) |
| DCI 4K | 4096 x 2160 | 1,89:1 (256:135) |
| Ultra HD 4K | 3840 × 2160 | 1,78:1 (16:9) |
Horizontally, almost all of them are close to four thousand pixels, but the vertical resolution directly depends on the aspect ratio. True 4K in this case is called DCI 4K, used in cinema. However, the aspect ratio of this format was not suitable for monitors and televisions. That is why the Consumer Electronics Association (CEA) in 2012 approved a single 4K format for digital electronics, which was called Ultra HD 4K.
This means that if 4K is indicated on the box of a monitor or TV, then according to the accepted specification it will have a resolution of exactly 3840x2160.
The situation is similar with 2K - DCI 2K 2048x1080 is considered true, but among monitors and TVs, 2K is understood as UWHD (2560x1080) or QHD (2560x1440) formats.
By analogy with the already established 2K and 4K, the 8K format corresponds to a resolution of 7680 × 4320 pixels.
How to check smartphone screen resolution
Screen resolution is a value that determines the number of pixels per unit of area. Screen resolution is expressed in the number of horizontal and vertical pixels, for example, 1280x720. This means that the width in the example is 1280 pixels and the height is 720 pixels.

Why do you need to know your phone screen resolution?
One of the main parameters in a cell phone or tablet is screen resolution. Today, developers offer many entertainment applications, games, music and programs for interactive communication devices. Naturally, this imposes certain requirements on the characteristics of a mobile phone.
It should be noted that manufacturers of applications and other types of software strive to reproduce the compatibility of the device and the program as much as possible. In other words, regardless of the type of gadget or the preferences of the owner of an iPhone or iPad, games should run and not freeze.
In achieving this goal, the RAM of the device plays a certain role. However, the main criterion is the screen resolution. After all, a properly selected application size allows you not only to launch it, but also to provide support for management functionality.
In addition, with the right choice, gadget owners will not complain about white stripes along the edges of the screen or various degrees of image stretching/compression. A legitimate question arises: how to find out the screen resolution of your phone?
Tips for choosing a gadget model
If you decide to change your device to a more modern one, then you should study the information on each model in advance.
- So, initially you determine for yourself the range of functions that are most frequently used. This could be a device with a protected case (resistant to shock, moisture, dust), with 2 SIM cards, a good camera or a powerful battery.
- Now you need to figure out which form of gadget you prefer. Cellular devices are available for sale in the form of clamshells, sliders, touch screens, and classic versions.
- In most cases, the choice falls on the touch screen. It is divided into 2 types - is the stylus or finger the control element? In the first version, a stylus stick is provided in the kit. Models of gadgets of this type make it easy to draw and type SMS. However, the control element is often lost.
- Now it’s time to determine the characteristics of a smartphone or iPhone. At the time of purchase, it is better not to trust sales managers. Therefore, the question of how to find out the phone screen resolution becomes most relevant. If you carefully read the recommendation article, then you already know the basic methods for determining this parameter. You should also find out if the gadget has other functionality. This refers to RAM, the ability to install a built-in card, Bluetooth, Wi-Fi, etc.
What is screen resolution?
At the very beginning, we determined why it is so important to pay attention to this characteristic. However, they did not define such a frequently used term. Let's fix this error?
Screen resolution is a quantitative expression that allows you to decide how many points in two planes (vertical/horizontal) the gadget’s screen will contain. Each point is a pixel.
For example, one of the popular tablet screen resolutions is 800x600. If we translate into our language, then the horizontal of the gadget’s monitor contains 600 pixels, and the vertical – 800. The higher this figure, the clearer the image will be.

PPI and device type
Now let's take another device for comparison. For example, 65-inch Sony KD65A8BR2 TV.
With a resolution of 3840x2160, the pixel density is only 67! Why so few? Because we watch TV at a distance of 2-5 meters, and not 25 centimeters. And the same 1 arc minute at 2 meters corresponds to 0.5 mm. Those. the maximum PPI at this distance will be only 50.
It turns out that each type of device has its own “good” PPI indicator. After all, we hold the smartphone almost close to our face, the tablet further away, the computer monitor almost a meter from our eyes, and farthest away is the TV. So what should the screen pixel density be for each device?
Taking into account all of the above, today the optimal PPI values for various equipment are as follows:
