Input Lag Vs Response Time

Input Lag VS Response Time

High input lag and sluggish reaction times can both impair your game experience. It can become intolerable though if the input lag is too great. So, before looking for the display with the fastest response time speed, first, make sure the input lag performance is adequate.

Despite having a limited budget, you still want to purchase the greatest monitor possible. Input Lag VS Response Time then, should you prioritise? Do not be scared; we are here to assist you in resolving your issue. This article presents a comparison of the ideas of input lag and response time in a brief manner that may be of assistance to you.

Knowing the notion can help you compare input lag and reaction time more effectively if you wish to do so.

1.How Does Input Lag Work

Input Lag Vs Response Time  :

1. How Does Input Lag Work?

Input lag refers to the delay between pushing a key and seeing the outcome on the screen. An illustration will help to clarify this. Let’s say you’re playing FIFA. You just dribbled past a defender and are about to shoot. You hit the button, but the player didn’t shoot, so your shot was missed. In this case, input lag refers to the delay between pressing and acting.

2. What Does Response Time Mean?

You also have response time, on the other hand. Response time describes how quickly the colours of the pixels on your monitor change. In a nutshell, it refers to how quickly each pixel switches from black to white and vice versa.

 You can imagine it as the monitor naturally showing black when nothing is being played, but grey or white when some background scenery appears.           

2.What Does Response Time Mean

When you play, response time may not seem important, but it actually is. This is due to the lag that occurs when objects are displayed on the screen due to a delayed response time. How will you input the appropriate action on your device if you can’t see what’s happening in real time? The response time becomes suddenly even more important.

The capabilities of a monitor or TV panel determine the response time. A 1ms response time is considered to be already quick in terms of response time, which is measured in ms (or milliseconds).

Narrow viewing angles and poor colour quality characterise TN (twisted nematic). In order to view everything, you must be directly in front of the screen. The benefit of this is that TN has the quickest response time. The best option is TN if a quick and fluid gaming experience is your top goal.

If there is such a thing as a middle-of-the-road display, it would be the IPS (in-plane switching). Although it is far superior to the VA, it is not as good as the TN. However, IPS versions from more recent generations today have quick response times. Some already have an advantage over TN by having only about 1ms.

The VA is the last (vertical alignment). Because the pixel can almost perfectly reproduce the colour black, the VA contrast is likely the best. The catch is that you have to wait a little longer for the pixels to transition from black to lighter tones. For quick movements, the screen will occasionally smear.

Input Lag Vs Response Time (Value) :

Gaming and other activities place a lot of value on both input lag and response time. You will comprehend more if you are familiar with them.

Input Lag

Smoothness will result from having a greater refresh rate or shorter input latency, and that is highly crucial. By providing you with a smooth pace on the screen and a delay-free gaming experience, a faster refresh rate enables you to have a better experience.       

Response Time

Response Time

Response Time You may be aware that the response time is the length of time needed for a single pixel to switch from one colour to another. You need a faster response time if you suggest a seamless graphics-changing experience. A first-person shooter game places a lot of emphasis on response time. You require a smooth, fluid-like visual transition and a clear visualisation of the entire screen.

Gamer’s Perspective:

Response time and input lag are very significant factors in gaming. To play competitive games, you must have a lag-free, fluid experience because, without it, you will have trouble timing your moves and will lose. Input lag is used to describe this.

Ideal environment for gaming

While response time in this situation refers to the amount of time required for the pixel to shift from one colour to another. A faster response time will make it possible for you to play first-person shooter (FPS) games with the seamless picture-changing quality that you require.

The Ideal Environment for Gaming:

As we previously learned, response time is the amount of time it takes for a colour to shift from one to another while input lag is the amount of time between pushing the controller and seeing a response on the screen. 

Many monitors have specialised gaming settings for input lag. To improve your gaming experience, turn on the game mode for the monitor.

However, for the optimal gaming experience, response time should be extremely low; else, ghosting will occur. Response times can be as fast as 1 or 5 milliseconds. While a 5-ms response time is ideal for gaming, some modern monitors provide a 1-ms response time, allowing for a significantly smoother gaming experience.   

Can response time and input lag coexist?

Can Response Time and Input Lag Coexist?

They can blend together, sort of. Now that you know, you can change the graphics colour on your monitor at any time during the response time. You will notice changes in the picture and act more quickly the lower the response time.

Thus, you must have the least input lag and response time for the best gaming experience. A lag tester is a crucial gaming tool because of this. It combines the effects of reduced response time and input lag. 

What Is “Ghosting”?

Increased response time or decreased refresh rate results in ghosting. After listening to this example, you’ll understand everything. Imagine you’re taking part in a racing game. Suddenly, a hazy image appears on your screen as you are moving through a location. Ghosting is the term for that behaviour.

However, you might not say it in any case if you use a monitor with a higher refresh rate.

What Should You Prioritize More?

The primary issue of what to prioritise is now at hand. In that regard, we’ll keep things straightforward.

What Should You Prioritize More

It goes without saying that you should look for both desirable features if you have the money. However, if that is not the case, you should search for reduced input latency. Because a bigger input lag will cause a lot of disruption in the game.

Although crucial, response time is not as significant as input latency. You won’t need to choose a 5-ms or 1-ms reaction time because 30ms will be plenty for gaming with less input lag.


This article focused entirely on my experience with Input Lag VS Response Time.

Response time and input latency were briefly mentioned above. These two will be explained in detail in this post. This will resolve your monitor selection issues.

If you want to choose a monitor of comparatively inferior quality, you should keep in mind that the input lag should not exceed 32ms before looking at the reaction time for the greatest experience.
