Monitor response time: What is it, how to find out what affects?

Video game technique must meet specific requirements. Unlike other tasks and processes, most video games are focused on the speed of decision making and player's response. This is especially true for online games, in which people's competition occurs. As in any other sport, the role is plays not only the skills of cybersports, but also a "sports equipment". First of all, it is a powerful processor, a video card and RAM. However, you should not forget about another component of a successful game - mapping a picture. Many families are the term "ping" - a temporary segment for which the data falls from the PC to the server or computer of the opponent. However, there is another delay factor to which you can and should be influenced. We are talking about such a parameter as the response time of the monitor.

What is the computer monitor response time

What is the computer monitor response time

In computer technologies, the reaction interval is the time required by the system to respond to the modified data. Monitor response time is a period of time required by a pixel to change the color of its glow. Globally is a time that passes between the renewed signal arrival on the monitor and its mapping matrix. The delay is so small, which is measured in milliseconds.

In the game process, the monitor response can be safely added by the network delay time. We will illustrate this on the example: in the online shooter, the player appears due to shelter. The time that will notice the opponent's player can be calculated by the sum of the following factors:

  • Ping Player Movement
  • Server Delay
  • Ping player rival
  • Renate video card delay
  • Monitor response time

Of course, each factor individually is minimal and unpacked for the eyes. However, the combination of these time segments may be sufficient to obtain a tactical advantage in the game (especially in dynamic).

Measurement methods

Measurement methods

Like any other value, the response is inherent in the unit and method of measurement. If we were determined with the first (this is milliseconds), then the measurement method is somewhat more complex. The fact is that, in contrast to physical quantities, the screen delay at different times was determined by four ways. Each of them was good at one time and can be found in certain brands. Next will be briefly listed these methods and what principle they are used.

GTG.

The Gray to Gray method shows how long it is required to switch between the shades of the monochrome image. The gradations from 90-80% to 10-30% are most often used. The most popular way to evaluate the response due to its versatility and approaching to real use conditions. It is now used to determine the technical characteristics of most produced displays.

Btw.

The Black To White method shows how quickly the pixel will go out of the extinct. The method is distinguished from the realities of the use of displays, therefore not used in the characteristics of the technique.

BTB or BWB.

The monitor response time is calculated from three quantities: off-bright-off. The method also stopped applied due to the fact that in operation such "extreme" conditions are not used.

MPRT.

The so-called "cinematic response". The method allows you to make sure that the image with a sharp stop does not reserve the "tail". This method allows you to simultaneously evaluate the frequency of the matrix update.

What is influenced by

At the beginning of the article, it was briefly described that it represents the response of the matrix and what scheme it works. Recall an example that was given. The display delay is summarized not only with the time processing time on the PC, but also with the ping of the Internet connection. It seems everything is clear, but this parameter has its own subtleties. Next, the article will show the importance of the value of the delay for games, possible negative points that may arise due to a low delay, as well as how to affect the response parameter.

Monitor response time for games

Monitor response time for games

Games, especially multiplayer, make serious requirements for the speed of the reaction. The response time of the gemina monitor must be no more than 5 ms, but even this parameter is considered insufficient. The best gaming displays correspond to 1 ms value. In a timely manner, up to a split second, see the danger and react to it - the key to the victory in any dynamic game. And we are not only about shooters. RPG, football simulators and races - in any genre from the listed speed of the reaction solves much. The presence of a quick game screen is comparable to professional sports equipment: directly without improving the player's skills, it becomes a serious help to achieve success.

Another response characteristic is the frequency of the matrix update. The higher this parameter, the more smooth the picture turns out. A direct value of the frequency on the effectiveness of the player does not affect, but there is an indirect impact. The twitching picture leads to the fatigue of the eyes. Concentrating in its own state, the player will be unable to respond to events in a timely manner. In addition, some jerking video causes irritation, which also reduces efficiency in the game.

What are the shortcomings of fast response

What are the shortcomings of fast response

As we have already found out, the response time of the monitor gives a boost to user performance in shooters and other video games. However, there are no ideal monitors, and when the balance in the direction of the acceleration of personnel sweep will suffer, other technical specifications will suffer. First of all, this is saturation and color reproduction. The process of proper color display is quite complicated, so it takes a certain amount of time (which becomes the delay).

To speed up the process of color change, a number of developers go to the easiest way - reduce the number of data processing steps. "Under the knife" is there technologies that reduce eye loads (Flicker-Free, etc.), color filters, accurate color correction and other utility. Therefore, the monitor, sharpened under the gameimility, is hardly suitable for designers, photographers and other professionals, for which the color reproduction is in the first place in the list of priorities.

How to change the response time in the monitor

How to change the response time in the monitor

Display, like any other technique, has a number of opportunities to improve. However, unfortunately, the response time on the monitor does not apply to this list. This parameter only affects the hardware, and therefore it is impossible to improve it. It will only help the screen replacement.

However, improving the display for gemina is still possible. To do this, you need to change the other important game parameter - the frequency of updating the matrix. You can achieve this software through Windows. The process of improving the update frequency is called the monitor acceleration. But about the desire to change the response time of the monitor you can forget - if this parameter is critical, it is easier to start searching for a new device.

What types of monitors are the fastest

As already mentioned, the response time of the monitor is the result of technological solutions in the manufacture of the matrix. Consequently, the display will depend on the type of matrix. Of course, this does not mean that a certain type of panels cannot find a single response installed for the entire line. The models are different, but they have noticeable differences, which determine the scope of their application. List three types of matrices that are often used in game monitors.

  • TN and its modifications. In the field of production of monitors, they are considered the most high-speed matrices, plus and inexpensive. Of the minuses it is worth highlighting a bad color reproduction. Based on such panels make budget game screens.
  • IPS are considered leadership matrices from the point of view of color reproduction, which makes them by default slightly slower. Manufacturers reaching 1 ms delays on such panels make great efforts. Such screens are suitable for professional gaming.
  • VA average between the two previous species.

Outcome

The response time of the monitor is a parameter, vital for games with a focus on the reaction. The less he will, the better. The delay value cannot be changed, so it's better to pay attention to it when buying equipment.

The choice of the monitor requires a careful study of its capabilities. Diagonal, resolution and update frequency, undoubtedly significant parameters, but not only they affect the comfort of operation. The expensive model with impressive characteristics may not be prepared for dynamic scenes and computer games. To do this, take into account the response time of the monitor.

The screen is a link between the user and the computer, so the discrepancy between the display parameters limits the potential of the entire system. On the old monitor, it is hardly possible to feel the difference between the top and mediocre "hardware".

Response time - what is it

Under the response time, the time interval is implied to the pixel to change the brightness of the glow. This is the time required by the pixel to switch from one color to another. The parameter is measured in milliseconds (MS). The response time is also called the display matrix delay.

Monitors with minimal time better display dynamic scenes. Fast switching between pixel colors provides maximum detail of each frame.

The video effect in computer monitors provides a quick frame change, which, unlike the film, do not carry information about the following and previous frames. Blur clearly demonstrates that the pixels did not have time to change the color to the desired one. Hence: The less the response time, the better.

The response time is associated with the screen update frequency. At a speed of 60 frame / with a new image, every 16.7 ms is generated. In one second, 1000 milliseconds. To find out the generation time of the new frame, you need 1000 to divide the screen update frequency. The longer the response time, the less time the correct image is retained on the screen. Because of this, the loop and the blurred movement appear. In such conditions it is difficult to see and determine the exact location of the moving object.

Measurement methods

The response time demonstrates the physical capabilities of the monitor matrix. It seems simple, but it is not. Manufacturers use different techniques and measurement conditions, and not always publish them. The difference in testimony may differ in 2 or more times. The use of different measurement methods creates a real chaos.

GTG.

GTG (Grey to Gray) - demonstrates the switching time of the pixel between the shades of gray. According to ISO 13406-2, the standard method is considered to be a measure of the time interval, which is needed by a pixel for transition from 90% to 10% brightness. In practice, this does not always correspond to reality, and manufacturers often choose their own meanings. For example, from 80% to 30%.

Most often, the response time is indicated in GTG. The parameter is considered the closest to the actual operating conditions. In reality - the response time from different halftones is different. This means that the bright areas will switch at the other speed than the dark.

Btw.

BTW (Black To White) - displays the time required by the pixel to go from the state turned off to 100 percent brightness. This method is considered obsolete, and is currently not used to designate the response time.

BTB or BWB.

BTB or BWB (Black White Black) Shows the transition time from the turned off the pixel state to 100 percent brightness, and then back to the off position. Actively used in the past, but gave way to the GTG method. Cause: The image on the display is rarely subjected to global transitions between colors, although this indicator is most fully demonstrated by the matrix delay time.

MPRT.

MOTION PICTURE RESPONSE TIME - the response time of a moving image, which is still called cinematic response. Some brands indicate this parameter with GTG.

MPRT is not a pixel response time. This is a matrix reaction to a movement that clearly shows the time of the existence of the loop. Simple words: the train will disappear during such a time with a sharp stop of the object. MPRT more depends on the screen update frequency, although the connection with the pixel response time also has.

To shorten MPRT, developers use MBR (Motion Blur REDUCTION). This technology is based on the principle of a stroboscope, which implies a short-term disabling of the backlight at the end of the frame time. This transition does not notice the naked eye, but visually dynamic scenes become clearer. True, the MBR technology is incompatible with an adaptive update.

Real MPRT more GTG response time, which is shown on the chart above.

Is it possible to measure the response time yourself

It has already been mentioned that the response time is the physical property of the matrix. It will be measured independently will be problematic. Without expensive equipment and measuring instruments, the calculation error will be tangible.

It is impossible to read this parameter by software without a photo sensor, although the TFT Monitor Test developers have taken such an attempt. The creators did not indicate exactly how the calculation is carried out. Under equal conditions, two monitors can give one result, so it should not be relying on the complete accuracy of the test. However, the utility has several useful modes, among which a moving white square. The presence of a loop and visual distortions give a great response time, but this is just a visual demonstration.

For testing, the Pixperan Testing utility can be useful, as well as online tests Display Shin0by and Blur Busters UFO Motion Test.

Overclocking monitor

To speed up the output of the matrix, use the OverDrive mode (OD) or Response Time Compensation (RTC). Each manufacturer of monitors has its own acceleration technique, but the overall essence comes down to one: a short-term increase in voltage pulses for accelerated rotation of the subpixel crystals. The overclocking of the matrix in OverDrive mode is safe, and does not lead to a reduction in the service life of the monitor. On the possibility of improving the response time, the presence of a game mode in the characteristics of the model can be said.

In all, you need a measure, and in the acceleration of the monitor too. Maximum response acceleration can cause another problem - Overdrive artifacts.

Overdrive artifacts are light flicker.

Manufacturers offer users a set of several Overdrive mode settings, from which the appropriate option can be selected.

In what cases is important the minimum response time of the matrix

Special attention is paid to the parameter gamers, and not just like that. The high speed of switching pixels in games can become a real advantage. Thanks to the minimum matrix delay, you can see important details in saturated dynamic scenes and respond timely to changes in the situation.

What does it give? For example, in shooters with the help of a "fast" monitor, you can earlier notice a sniper in the window opening. Clemented, too, will be much more comfortable, because the enemy with a "slow" monitor will not even notice an ambush.

The higher the skill of the gamer, the more advantages gives the "insignificant" difference in just a few ms.

In fairness, it is necessary to indicate that other types of delays affect the player's response, among which Input Lag, the stability of the Internet connection (for online games), the signal transmission time from manipulators, but this is another story.

Required players can feel the difference of response time in any game, regardless of the genre. Even in popular browser games by the type "Three in a row". In many of them there is a timer, therefore the player's reaction rate is important. In addition, dynamic visual effects look better on "fast" monitors.

Reducing the response time will make animation detailed, clear, and therefore more attractive. On the monitor with minimal response time more pleasant to play.

An exception

In monitors for content creators, more attention is paid to the accuracy of color reproduction and expansion of the colors palette. That is why the response time in such cases is postponed to the background.

From this it follows: not all models of the selected price category are equally suitable for games or work.

Hello dear readers. Monitor response time What is it and do we really want to know the terrible truth? If yes, read today's publication. In it, I will figure out this characteristic in detail, and, as always, I will give several valuable tips for choosing the device of interest.

Subscribe to the newsletter so as not to miss new interesting posts!

A bit of theory

With warmest and lamps of the monitors, everything was easier: the frequency of the winding scan clearly gave to understand: 60 Hz is good, and 120 and 144 - twice the best. In fact, this value shows how many times the picture on the screen will be updated.

However, without panic: this characteristic is not doing anywhere and is still indicated on any decent site. For example, in this wonderful online store, where you can buy a monitor for any task.

However, the technologies were evolved, and a LCD panels came to replace the usual kinescopes. There are several parameters that differ in different types of matrices - color rendition, dynamic contrast, an angle of review, and so on. It is logical that the response time may differ.

What does this characteristic mean? It would seem that nothing special is just time in milliseconds that requires a pixel to change the brightness of the glow. Yes, it is in milliseconds that is measured - engineers in bringing such matrices to perfection are so meticulous.

What does this mean in a practical plan

The more response time, the longer the monitor will respond to the already changed picture. This is absolutely no important, for example, when working with a text document or spreadsheet: not so faster prints most users to notice that the monitor "Tupit".

The parameter is almost not taken into account and when working with graphics and video processing: it is already more important that the monitor makes the full palette of paints and distorted them as little as possible.

However, the response time is very important for games, as well as when viewing blockbusters with chains and shootouts, where the scenes replace each other with a rigorous speed.

I want to note that in the case of games, speeches does not go about shooters and other dynamic fun - even a primitive casual from the category "three in a row" suggests that the picture, let and in some areas of the monitor, will constantly change, and pretty quickly.

Add all the effects and animation here, which the developers add, and you will get a complete picture. Why animation? With such a competition in a niche in the game, where three blocks of the same color simply disappear, almost no one will play, guarantee.

It is necessary that the discharges of the lightning, grumble, from the side of the virtual assistant praised the wise owner, everywhere all glistened and sparkled, and at the end of the round, the cute beauty of the hero of the hero of air kisses.

And since the game began, I will tell you about the complete opposite. And it's better to make a riddle of you (or ask a realness test, as you please): In what situation in the rapid online shooter the picture on the screen does not change for a long time? Right answers are waiting in the comments.

But we were a little distracted. A lawsuit may arise - is there a difference between 1 ms and 4 ms? It would seem not. Suppose, not every stopwatch will fix such a magnitude, except that electronic.

But the human eye, one of the most perfect creations of the Mother of Nature (after the eye of the eagle, of course), this difference sees perfectly. Moreover, the eyes have time to react and with a less response time.

Advanced gamers have time to react and brain, and professional cybersports also have time to send the appropriate command limbs. Those who at the same time have time to react and manage to get along the right buttons are usually located on the top of the ranking in some championship.

Or, for example, in the Table Leaders of the PVP-oriented Online Game, where the "direct hand" is affected by the victory, and not the number of money difficult to equipment.

What response time is considered acceptable for games:

  • Low - up to 2 ms;
  • Average - 2-5 ms;
  • High - over 5 ms.

And now the main thing is to which I led throughout this publication. For a comfortable game, regardless of the genre, a response time is required no more than 2 ms. Professionals also prefer the monitor with even a smaller indicator - up to 1 ms.

At the current stage of development of technology, this can offer only one type of matrices - TN. Or rather, TN + FILM, since "clean" TNCs have not been issued for a long time.

What is the best time for other tasks, if you are not a gamer and not a movie lover? There is no difference. At all.

Than measuring response time

The most common way to measure the response time of the GTG response is most common, that is, a reduction from "green to green". The characteristic shows how much time you need a pixel to change the brightness from 90% to 10%.

This method of measurement is very like marketers and sales departments: even the cheapest matrix can show a decent result in this case.

More accurate data can be obtained when measuring the BWB method, that is, "black to black" - the time for which the pixel switches from black to white and back into black. Sometimes used and BTW - the time of switching from absolutely black color to the full luminosity of the pixel.

I think you have already guessed that almost all manufacturers of monitors indicate the response time measured by the GTG method. For measurements, a complex hardware and software package is used, which is not in every service center.

At the domestic conditions, check how much the manufacturer has deceived us, you can use the TFT MONITOR TEST utility. There is nothing difficult: the program chases multicolored geometric shapes across the screen and after measurements shows, oddly enough, quite a plausible result.

And in conclusion I want to say that the matrix response time cannot be changed - nor in the settings or anything else.

Is that you - the Great Magician and Cudesman who knows how to change the physical properties of material objects. But in this case, I suppose you have a little other interests, and the monitor is not particularly needed, right?

And in conclusion, I want to recommend correctly and not expensive gameimarian device with a response time 2 ms - SAMSUNG S24D300H (300HSI) . Share this publication on social networks if it is useful for you. While!

PS: One of the correct answers: when you play for a sniper and in ambush Kerper.

What is a computer monitor response time?

If we speak dry scientific language, then the response time of liquid crystal monitors is the at least the time you need a pixel to change the brightness of the glow and is measured in milliseconds. (MS)

It would seem - everything is simple and understandable, but if you consider the question in detail, it turns out that these numbers hide several secrets in themselves.

Comparison of monitors with IPS and TN matrix

Some science and history

Time of warm and lamps CRT monitors with honest heads of frame scan and RGB color has already passed. Then it was all clear - 100 Hz is good, and 120 Hz is even better. Each user knew that these numbers are shown - so many times a second updated, or blinks, the picture on the screen. For a comfortable viewing of dynamically changing scenes (for example - movies), it was recommended to use the frame rate 25 for TV and 30 Hz for digital video. The basis was the approval of medicine that human vision perceives the image continuously, if it blinks at least twenty-five times per second.

But the technologies were evolved, and the baton at the ELT (electron-beam tube) took the panels on liquid crystals, which are still called LCD, TFT, LCD. Although production technologies differ, but in this article focus on trifles will not, we will tell about the differences in TFT and LCD another time

What does the response time affect?

So, the principle of operation of the LCA is that the cells of the matrix change their brightness under the influence of the control signal, in other words - they switch. And this is the speed of switching or response time, just determines the maximum shift speed of the picture on the display.

мониторы с различным временем отклика матрицы

The usual hertz translates according to the formula F = 1 / t. That is, in order to obtain the necessary 25 Hz, it is required to provide a pixel speed of 40 ms and 33 ms for 30 Hz.

Is there a lot or a little, and what time of the response of the monitor is better?

  1. If the time is great, then artifacts will be shown with sharp changes in the scene - where the black matrix is ​​still showing white. Or an object is displayed that has already disappeared from the field of view of the camera.
  2. When the human eye shows fuzzy pictures, then the fatigue of the view increases, headaches may appear, increase fatigue. This is due to the visual tract - the brain constantly interpolates the information coming from the retina, and the eye itself is occupied by the continuous change of focus.

It turns out that less is better. Especially if the computer has to be held most of the time. An older generation remembers the times how hard it was to sit before the CRT eight-hour working day - and they provided 60 Hz and more.

How can I find out and check the response time?

Although milliseconds they are in Africa milliseconds, but for sure many have come across the fact that different monitors with the same indicators form an image of different quality. Such a situation has developed due to various methods for determining the reaction of the matrix. And what method of measurement applied the manufacturer in each case, it is unlikely that it is unlikely to be possible to find out.

There are three main methods of measuring monitor response:

  1. BWB, it is BTB - Abbreviation of the phrase of English "Black to Back" and "Black-White-Black". Shows the time for which the pixel switches from black to white and back into black. The most honest indicator.
  2. BTW - decrypt as "Black To White". The inclusion of an inactive state to one hundred percent luminosity.
  3. GTG is a reduction from Gray To Gray. How much point is the point to change the brightness of gray with ninety percent to ten. It is usually about 1-2 ms.

And it turns out that checking the response time of the monitor by the third method will show a much better and attractive result for the consumer than checking the second. But you will not have to - write that 2 ms and so it will be. Yes, only on the fact on the monitor and artifacts climb, and the picture is a loop. And all from the fact that The true state of affairs shows only the BWB method. - The first method, it is he indicates the time required by the pixel for a full-time cycle in all possible states.

Unfortunately, the documentation available to consumers does not clarify the picture and what is meant by, for example, 8 ms is difficult to understand. Will it work comfortably work?

For laboratory research, a rather complicated software and hardware complex is used, which is not in any way there is a workshop. But what if I want to check the manufacturer?

Checking the monitor response time at home is carried out by the TFT Monitor Test program .Choosing the test icon in the Softin menu and specifying the native screen resolution on the display displays the picture with a rectangle driving there and here. At the same time, Programline proudly will show the measured time! программа TFT monitor

We used version 1.52, checked several displays and concluded a program - the program shows something, and even in milliseconds. Moreover, the worst quality monitor demonstrated the worst results. But as the time of quenching and the ignition of pixels is recorded only by the photosatchik, who was not in mom, then a purely software method can be recommended for a subjective comparative assessment - which measures the program is understandable only to its developers.

A much more visual empirical test will be the "White Square" mode in the TFT Monitor Test - the screen is moving on the screen. White square, and the task of testing is observed behind the loop from this geometric shape. The loop is longer, the more time the switch is spent by the matrix and the worse its properties.

That's all that will do to solve the problem "How to check the response time of the monitor". To describe methods using cameras and calibration tables, we will not consider them another time - it will be necessary for a couple more days. A full-fledged check can only be performed by a specialized organization with an appropriate technical base.

Response time in monitor for games

If the main purpose of the computer is the game, then you should choose a monitor with the smallest response time. In dynamic shooters, even the tenth percent of a second can solve the outcome of the battle. Therefore, the recommended response time of the monitor for games is not more than 8 ms. This value provides the frequency of shift frames of 125 Hz, and will be absolutely enough for any toy.

With the next next value of 16 ms, the movements will be observed in hard fuses. These approval are true if the claimed time was measured by BWB, but the company of Lugowe can write 2 ms, and 1 ms. Our recommendation is unchanged - the smaller the better. Based on this approach, let's say that the response time of the monitor for games should be at least 2 ms as the 2ms GTG approximately correspond to 16 ms BWB.

How to change the response time in the monitor?

Unfortunately, without replacing the screen - almost no way. This is the characteristic of the layer itself responsible for forming a picture, and corresponds to the manufacturer's project solution. There are of course a small loophole and engineers solved the question: "How to change the response time."

Companies producing monitors call this feature Overdrive (OD) or RTC - compensation of response time. This is when the pixel is briefly served a higher voltage pulse, and it switches faster. If the monitor sparkles the inscription - Gaming Mode or similar, then you know - it is possible to adjust for the better. Once again, it is clear, so that it is completely clear - no programs and replacement of video cards will not help and do nothing to twist - this is the physical property of the matrix and its controller.

findings

By buying a video card for a thousand-toxolong conventional units to drive your favorite games at least a hundred FPS, and feed the video signal to the monitor, which and forty Fps barely pulls out, is slightly irrational. It is better to give a hundred on the display and enjoy the full dynamics of games and movies without disappointments - from 40 ms Matrix of pleasure you definitely do not get, and the joy of possessing a powerful video adapter will block poor image quality.
