Pixel response time of your display refers to response time. Response time depends on the amount of time taken by a pixel of your display to change black into white or from shades of gray to another color. In LCD, a response time depends on how many frames are displayed each second. Display response time is measured in 1ms (one-thousandth of a second). The lowest number in response time (2>4) means faster transition. A longer response time would create motion blur around moving objects on display, while a higher response time means fewer visible image artifacts. Black to white is regarded as true response time and gray to gray is used as marketing strategies of companies. Black to white response time will be always a little higher than gray to gray response time.
Is 4ms Response Time Bad or Good?
In most modern monitors, there are two types of panels are used, Twisted Nematic Panel (TN) and In-plane Switching Panel (IPS). Both of them are different from each other and they both have some advantages and disadvantages. They have a different response time. Response time for display with TN panels is 1ms, whereas displays with IPS panels have 4ms response time. Monitor with higher response time can be affected by any GPU lag. Here, the lower response time could help to keep a smooth flow of graphics on your screen without any noticeable lag.
However, most of the monitors available in the market come with a response rate of 5ms. Also, you will find monitors with 1,2,4,8,10ms response time in the market. A monitor with a faster response rate will cost more than the lower one.
In terms of response time, the lower is the better. This means a display with a 4ms response time is a better choice than a display with a 5, 6, 8, 10ms response rate. From this point of view, a 1 ms response rate is better than 4ms, but a 1ms response rate is only available on displays with Twisted Nematic Panels. So, if you want to use displays with In-plane Switching panels, then a 4ms response rate is good for you.
Is 4ms Response Time is Good for Gaming?
The average response time of the human brain is 250ms. 1ms is one-thousandth of one second and 4ms is four-thousandths of one second. In comparison with the response rate of the human brain, both of them are very small amounts of time. So, the average human brain won’t be able to spot the differences between them. In PC’s used to complete simple tasks 5ms response rate is good, but in gaming displays, 1ms and 4ms are good. Though, the response time of display also depends on input lag. Response time could be worst because of processing signals.
A monitor with a faster response time is a must for gaming. If you are a sensible and competitive gamer, you have to interact with the game as fast as possible. If you are currently using a display with a response time of 5 or 8ms, it won’t be perfect for gaming. You need to use faster displays that have a faster response rate than 5ms. In this case, 4ms displays will be a great choice.
Frequently Asked Questions (FAQ)
What is 4ms?
4ms or 4 millisecond is four-thousandths of a second. Though it is a very little amount of time, for a computer it is a little slower. 1ms is faster than 4ms.
Can 4ms beat 1ms in response rate?
Well, the response rate also depends on input lag. An IPS panel display with 4ms and 144h refresh rate can beat a 1ms TN panel display in actual response rate.
Which is better TN panel or IPS panel?
Between IPS and TN panels, IPS are typically expensive, but IPS produced higher display quality with better color and viewing angles. Displays with TN panels are great for a low and tight budget.
Before Wrapping Up
Now, you already know that the 4ms response rate is a mediocre response rate for gaming, but for normal use, it is more than good. if you are currently using a display that has a response rate of about 1 or 2ms then the 4ms response rate will be slower for you.
