Reorienting screen settings to reduce eye strain and improve performance is a question of interest to many users. The article talks about how to find out how many Hertz is in the monitor and correctly adjust its ergonomics. This is necessary in order to understand, make adjustments to the settings or leave them current version.
What is monitor hertzka and what is it responsible for?
Refresh rate is the rate at which LEDs pulse to pixels to change the colors, tones, and tints of the picture. It is measured in Hertz.
All processes take place by means of wideband pulse modulation. With its help, not only the image refresh rate changes, but also the brightness. The functionality of the regulator lies beyond the limits exceeding 60-100 Hz, when the visual analyzer practically does not respond to such a frequency, no matter how closely you look. A person simply does not notice the pulsation. An increase in the indicator is necessary so that the image on the display does not flicker.
To avoid confusion in settings and not to overload the eyes and hardware in most cases operating system independently adjusts the rate of change of the image to the frequency of a particular screen.
Instructions: how to check the hertzon of the monitor
Let's figure out how to see how many Hertz the monitor gives out if Windows 10 is installed. To do this, you need to follow the following instructions:
How many hertz is better for a monitor?
Given the different age groups of users, it is impossible to know the optimal flicker frequency.
Increasing the flicker frequency results in smoother screen movements, especially during gameplay. The level of load on the visual analyzer is also significantly reduced. To find out how many hertz is better for a monitor, you need to try working in several modes.
In most cases, an increase in user performance and a decrease in fatigue is observed when the ripple exceeds 100-150 Hertz. But the flicker rate depends on the computer hardware as well.
An image source in any system is an element such as a video card. First, find out how many Hertz this component is capable of producing. If it refreshes the picture 60 times per second, then no screen settings will help to increase the frequency, no matter how much you use them. If the graphics adapter outputs 400 Hz, and the screen does not support such a frequency, it will automatically remain at the limit, installed by the device displaying the image. Experimenting with the settings, you need to find out what frequency the screen supports.
In order not to strain eyesight, and the picture on the monitor was clear and of high quality, users try to adjust various parameters. This question is still relevant, because even the most modern monitors have all the necessary options to customize the screen to fit your needs. One of the important parameters of the monitor is the image refresh rate, which is set by blinking pulses of LEDs supplied to the pixels. In this article, we will consider how to find out how many hertz in the monitor- it is this value that denotes the refresh rate.
So, the refresh rate of the screen is the frequency supplied to the matrix, which allows you to change the color of the pixel. All modern monitors have a frequency of at least 60 Hz. Thus, the higher the indicator, the faster the color change occurs, and without any defects. The change in the image will be such that you will not notice the pulse or flicker.
Operating systems, starting with Windows 7, independently adjust the screen frequency, like many other parameters. Usually, if the monitor supports 60 Hz, then this value will be automatically set. In order to still make sure what value of the hertz value is on the monitor, we will use the system settings. Windows.
Checking the hertzon of the monitor
While in the system, click on an empty space with the right mouse button and, in the context menu that opens, select the option Screen Options.
Go to section "Screen" on the left side of the window, and on the right side we go down a little lower and find the item "Graphics adapter properties".
In the "Monitor" section in the section Screen Options the maximum refresh rate option will be indicated. If not, try setting the highest frequency.
Approximately the same parameters in Windows 7 are located in the Control Panel, the "Display" section.
Which value is better
The higher the frequency, the smoother the picture and less impact on vision, but it is unrealistic to say exactly which value is better, because the options will have to be adjusted individually for each user.
The best option to understand how many hertz is better is to try to work with a PC with different frequencies set. Of course, a video card must also support certain frequency values, because if a monitor with 100 Hz or higher does not mean that a video card can produce this. The same is true and vice versa. By setting values of 100-200 and higher hertz in the settings of the video adapter, the computer will work only with values that the monitor supports, for example, only 60 Hz. Of course, support for all parameters can be found in the documentation and on the Internet. And then experiment.
If during work you feel fatigue and strain on your eyes, change the screen parameters.
I hope this article helped a little in how to find out how many hertz are in the monitor and, at the same time, reduce eye strain.
- Faster, even faster, well, speed up, please, at least a little, otherwise I am now ...
- I can't, dear Gamer, because I have reached my maximum clock frequency.
Something like this might look like a dialogue and Gamer, who counts every fraction of a second.
Clock frequency random access memory(RAM, RAM) - the second most important parameter after the volume. The higher it is, the faster the data exchange between the processor and RAM occurs, the faster the computer works. Low clock speeds can be a bottleneck in resource-intensive games and programs. And if you do not want to beg the capricious piece of iron to add a little speed every time, always pay attention to this characteristic when buying. Today we'll talk about how to find out the frequency of RAM from the description in store catalogs, as well as the one that is installed on your PC.
How to understand what kind of "beast" the store offers
In the description of RAM modules on the sites of online stores, sometimes not all are indicated, but only individual speed characteristics. For example:- DDR3, 12800 MB / s.
- DDR3, PC12800.
- DDR3, 800 MHz (1600 MHz).
- DDR3, 1600 MHz.
Some might think that this example is about four different slats. In fact, this is how one and the same RAM module with an effective frequency of 1600 MHz can be described! And all these numbers indirectly or directly indicate her.
In order not to get confused anymore, let's figure out what they mean:
- 12800 Mb / s Is the memory bandwidth, an indicator obtained by multiplying the effective frequency (1600 MHz) by the width of the bus of one channel (64 bits or 8 bytes). Bandwidth describes maximum amount information that the RAM module is capable of transmitting in one cycle. How to determine the effective frequency from it, I think, is clear: you need to divide 12800 by 8.
- PC12800 or PC3-12800- another designation of the bandwidth of the RAM module. By the way, a set of two strips intended for use in dual-channel mode has 2 times higher bandwidth, so its label may have the value PC25600 or PC3-25600.
- 800 MHz (1600 MHz)- two values, the first of which indicates the frequency of the memory bus itself, and the second - 2 times more - to its effective frequency. How do the indicators differ? Computers, as you know, use DDR-type RAM - with a double data transfer rate without increasing the number of bus cycles, that is, not one, but two conditional pieces of information are transferred through it in 1 clock cycle. Therefore, the main indicator is considered to be the effective clock frequency (in this example- 1600 MHz).
The screenshot below shows a description of the speed characteristics of the RAM from the catalogs of three computer stores. As you can see, all sellers designate them in their own way.
Different RAM modules within the same generation - DDR, DDR2, DDR3 or DDR4 - have different frequency characteristics. So, the most common DDR3 RAM for 2017 is available with frequencies of 800, 1066, 1333, 1600, 1866, 2133 and 2400 MHz. Sometimes it is denoted that way: DDR3-1333, DDR3-1866, etc. And this is convenient.
Not only the RAM has its own effective frequency, but also the device that controls it - the memory controller. In modern computer systems starting with the Sandy Bridge generation, it is included in the processor. In older ones, they are included in the components of the north bridge of the motherboard.
Almost all RAM can operate at lower clock rates than indicated in the specifications. RAM modules with different frequencies, provided that the other parameters are similar, are compatible with each other, but they are capable of functioning only in single-channel mode.
If the computer has several RAM strips with different frequency characteristics, the memory subsystem will exchange data at the speed of the slowest link (with the exception of devices). So, if the frequency of the controller is 1333 MHz, one of the bars is 1066 MHz, and the other is 1600 MHz, the transmission will go at a speed of 1066 MHz.
How to find out the frequency of the RAM on the computer
Before learning how to determine the frequency indicators of RAM on a PC, let's figure out how the computer itself recognizes them. It reads the information written in the SPD chip, which is equipped with each separate RAM strip. What this microcircuit looks like is shown in the photo below.
SPD data can also be read by programs, For example, a well-known utility, one of the sections of which is called “ SPD". In the screenshot below, we see the already familiar characteristics of the speed of the RAM bar (the field “ MaxBandwidth") - PC3-12800 (800 MHz). To find out its effective frequency, it is enough to divide 12800 by 8 or 800 multiply by 2. In my example, this figure is 1600 MHz.
However, in CPU-Z there is one more section - " Memory", And in it - the parameter" DRAMFrequency"Equal to 665.1 MHz. This is, as you probably guessed, the actual data, that is, the frequency mode in which the RAM actually operates. If we multiply 665.1 by 2, we get 1330.2 MHz - a value close to 1333 - the frequency at which this laptop's memory controller operates.
In addition to CPU-Z, similar data is shown by other applications that are used to recognize and monitor PC hardware. Below are screenshots of the free utility
One of the most important characteristics of a monitor is its refresh rate, or as it is also called "hertsovka". It is measured in Hertz and refers to the number of times the monitor screen is refreshed in one second.
For most modern monitors, the "Hertsovka" screen is 60 Hertz. This means that the image on the screen changes 60 times per second. For expensive ones, the refresh rate can be 100, 120, 144 or even 240 Hertz. This high frequency is needed in order to create a smoother and more comfortable picture in the game.
In this article, we will tell you how to find out how many Hertz your monitor has and how to change the “hertz” if the monitor supports this feature.
Monitor refresh rate in Windows 10
If you are using Windows 10, then in order to find out how many Hertz your monitor has, you need to right-click on the desktop and select "Display Settings" in the menu that opens.
As a result, you will see the "Screen" section in the "Parameters" menu. Here you can find out the used and the orientation of the screen, but there is no information about the hertz of the monitor here. To get this information, you need to click on the "Graphics adapter properties" link, which is located almost at the very bottom of the window.
In the window with the properties of the graphics adapter, go to the "Monitor" tab. Here, the drop-down list will indicate the current refresh rate of the screen.
If the monitor supports several modes of operation with a different number of Hertz, then in this drop-down list you can select a different frequency. If there is no such support, then only one frequency will be available in the list. For example, in the screenshot above it is 60 Hertz.
Monitor refresh rate in Windows 7
If you are using Windows 7, then in order to find out how many Hertz in the monitor you need to go a slightly different path. To get started, right-click on the desktop and select "Screen Resolution".
And in the menu that opens, go to the "Monitor" tab.
Here, as in Windows 10, there is a drop-down menu that indicates how many Hertz the monitor has at the moment. You can also select a different hertzka here, if it is supported by your monitor.
Monitor refresh rate in video card settings
You can also see how many Hertz your monitor has through the video card settings. In the case of a video card from NVIDIA, for this you need to right-click on the desktop and go to “
It is important that your monitor has the correct screen resolutions and refresh rate. At the same time, on modern LCD - TFT monitors, the resolution should be the recommended one for this monitor, otherwise the image quality will be poor.
But, for old CRT monitors, such a parameter is important as Screen refresh rate. If you have a CRT monitor and you want to preserve your vision, then you must constantly monitor this parameter (because sometimes the settings go astray spontaneously).
Right-click on an empty spot on the monitor screen (i.e., not on open window some program and not on the icon). The context menu opens:
In this menu, select: Properties
The Properties window opens.
Select the Parameters tab.
In the Display field you will see the name of your monitor and the model of the video card. And below is the Screen Resolution, which you can change if you want. Normal, standard resolution presented in the table:
But for LCD monitors, you need to set only the native resolution, no more, no less. Otherwise, the image looks blurry, the color rendition is distorted, and the work on such a monitor does not give any pleasure.
I first bought a 17 ”LCD monitor, but working at a resolution of 1280 x 1024 was terribly uncomfortable for me. In the eyes rippled, this spoiled the mood. Therefore, after suffering for a week, I exchanged that monitor for a 19 ”LCD and was pleased with the result. Frankly speaking, the 17 ”LCD is only suitable for games. Such a toy is not suitable for serious work of adults.
But there is more to come from this tab. There is also an Advanced button
We press it and a window with the properties of the monitor and video card opens in front of us. These windows may differ depending on the video card. 
What to look for on the General tab. The default scale here is 96 dpi. This is the usual size. Let it be so.
But below, note that the toggle button (the so-called radio button) should be in the following position:
After changing the display parameters, you should:
Apply new display settings
Otherwise, if you change the screen resolution or color quality (and sometimes you have to do it), then the computer. Do you need it?
Go to the Monitor tab 
This tab contains the most important parameter monitor - the refresh rate of the screen. I have 60Hz, which is the norm for an LCD monitor. But, if you have a CRT monitor and the frequency is the same, then this is awful! Your vision is in danger!
Actually, such a frequency can be found without looking at the display parameters. To do this, turn sideways to the monitor and look at the screen with your peripheral vision. If you see the screen flickering, then the monitor is time for a landfill (its frequency is 60-70 Hz).
Although, first open up and look at the Monitor tab. Perhaps no one installed correct frequency screen updates.
First of all, check the box “ Hide modes the monitor cannot use". And from the remaining digits, choose the maximum value. For LCD, I have chosen the recommended - 60 Hz. And for a CRT monitor, it must be at least 85 Hz.
If in the position with "Hide modes that the monitor cannot use", the maximum value is 85 Hz or more, then you are setting this value and you can still work with such a monitor. If the maximum frequency that the monitor can use is less than 85 Hz, then such a monitor is really time for a landfill, because vision is given to a person only once and you don't want you to be excruciatingly hurt later for aimlessly lost vision (I paraphrased Ostrovsky) ...
Personally, I immediately felt with my own eyes when the frequency went astray for some reason. Then I opened this tab, set the frequency to 90 Hz (for my monitor it was the maximum) and my eyes immediately felt comfortable.
So, you press the button and select the desired frequency from the list, which in most cases is in the range of 85-100 Hz.
Now click the Apply button and then OK.
Before clicking OK, I want to say that the rest of the tabs are not as important as the ones discussed. You can watch them, but you don't need to change anything in them.
The refresh rate of the screen is not that important if you have an LCD monitor. If you have an outdated CRT monitor, then the screen refresh rate must be checked. To do this, click on the link Extra options
