Response time is an important factor to look for before selecting a monitor for yourself. Check the response time of your monitor to ensure that it can handle gaming and high-end professional work.

For gamers, the response time of a monitor is key. The difference between winning and losing can be determined by a slow response time. Hence, you should check out the monitor’s response time before buying it. It is as important as other features.

In this guide, we will talk about how you can determine how fast a monitor responds. We’ll also show you different response time testing websites. and will let you know what’s considered to be a good response time for a monitor, So, let’s dig in.

What Is Response Time Testing, And How Does It Work In Monitor?

Response Time Testing (RTT) is one of the major quality control methods. This measurement is actually a way to measure how long it takes for pixels to change colors. Generally, the color transition happens via a change in voltage.

Response Time Testing is based on the premise that electricity follows the least resistance path. The longer it takes for a pixel to change, the higher the resistance will be, and the longer it will take for the pixel to change from one color to another.

This is why Response Time Testing is a useful quality control method for the monitor. Response Time Testing is a type of testing that measures how fast a monitor takes to get from a power-off state to a viewable picture. In the dark ages, monitor manufacturers used to measure this time themselves, with the standard being around 30ms.

Now that this standard is over, I would recommend you use a free utility from which does all the work for you and tests response time, input lag, refresh rate, contrast ratio, and black and white levels quite easily.

Response Time Test Monitor

It is a simple test that measures how long it takes for one pixel to change color from one color to another. This is important because it can help you determine whether a monitor is suitable for gaming or other high-response activities. A monitor with a fast response time will be able to display fast-moving images without blurring, while a monitor with a slow response time will tend to blur images.

How To Test The Response Time Of A Monitor OR How Do You Calculate Response Time?

1. Check The Specification

The easiest way to check the response time of the monitor is by looking into the specifications. Usually, companies provide a list of specifications and a “How to” guide with every device. So, you should check it in that file. If you are buying a monitor from an online store like Amazon, etc., you should look into the description part. I am sure you will find it. because they provide every bit of information related to the product.

2. Run An Online Test.

You should look for an online “response time tester” website where you can check the exact response time of your monitor. There are a variety of different websites available. Choose one for yourself! Let’s say you’re not sure which is the best option. We have two of them for you.

Search for EIZO on or just click At the bottom and middle of the screen, you’ll see “Start EIZO monitor test.”
Then select “response time” and you will get the result.


You can test the response time with software called “Lag Tester.” Download the software from here: After downloading, install it on your PC, and then open it. Select the option to test the display’s response time on the main screen. You need to enter the resolution so that the same can be used to test the response time.

What Is A Good Response Time For A Monitor?

When it comes to finding a gaming monitor, the general rule of thumb is that the lower the response time, the better. If the response time is under 5 ms, it is still considered good since it refreshes the pixels quickly enough to prevent motion blur. Although 1 ms is ideal.

Generally, people won’t be able to tell the difference between a 1 ms and 5 ms response time. However, there are some people for whom that gap in time makes a big difference. Professional competitive gamers, for example, who do high graphic-intensive gaming, may notice a difference in performance.

Examples Of Response Time Testing For Monitors

A pixel’s response time describes how quickly it changes from one color to another when agitated by an electric charge. It is also known as “transition time.” The transition time is recorded in milliseconds (ms).

It should be <16ms for the display to appear as a sharp, crisp, flicker-free picture to the viewer. The monitor should be tested to determine its response time through the test patterns provided by the manufacturer or by running an application. A response time tester is used to determine the response time as accurately as possible. A response time tester is an instrument that is used to measure the delay in the transition from one state to another. It is used in televisions, LCD monitors, and even projectors.


How Long Do First Response Digital Tests Take?

Digital testing takes 2–3 hours to get your first response. The first response from the digital platform is an indication that your ad has been served to a device and it is likely to show up on a search engine results page. It generally takes about two hours for a search engine results page ad to appear after you are approved on the Google AdWords platform.

What Is Motion Clarity Ratio (MCR) Or Clear Motion Rate?

Motion clarity ratio is the ratio of the highest spatial frequency you want to record in the image. When your camera or the subject moves during exposure, motion blur results in a loss of detail. This can be caused by the subject moving or by the camera shaking.

To get the best images of a scene, the highest spatial frequency of interest should be at least twice the number of pixels on the sensor. For example, if you are shooting with a 12-megapixel camera, the highest spatial frequency should be at least 24 pixels. Otherwise, you will have motion blur in your image.

How to Check Laptop Screen Response Time?

You may do it online to evaluate the speed of your laptop screen’s reaction. Several websites offer online testing of response times. We will use the EIZO website as an example.

Visit the EIZO webpage.
At the bottom and middle of the screen, you’ll see
“Start EIZO monitor test.”
Then select “response time”.
And you will get the result.


In the blog, we discussed the response time of a monitor and how it can impact the overall performance of a monitor. Moreover, we presented some ways to calculate the response time of a monitor. So, whenever you happen to buy a new monitor, apart from other features, look for a better response time monitor.
