What is Response Time and Input Lag? Reduce Input Lag For Gaming
Response Time and Input Lag: When it comes to the PC-based monitor and televisions with smart technology, speeds primarily come down to the response of pixels and input delay.
Both are measured in milliseconds and are, at a minimum, slightly interconnected.
They’re not identical in any way. Let’s start by defining the fundamentals.👇🏻
Simply put, the term response time (or “pixel response”) is the time it takes for a display to change the color of an individual pixel.
Millions of these are the basis of the entire image. In essence, pixels respond to the design of a screen.
With a quick response time, images appear clear and sharp instead of blurry and scattered.
In terms of input lag, it measures the amount of time between the signals coming from an input device like a gaming console, set-top box, or PC and the video displayed on display.
It’s all about the feel. Do you feel that the display responds rapidly to your inputs for control in the game❓
If so, you’ll notice a low lag or latency. If there’s a noticeable gap between wiggling a mouse control pad and moving on the screen, it is suffering from significant delays.
Response Time and Input Lag are crucial terms in the gaming world. Let’s discuss them in detail.

What is the Response Time?
The most widely used measure of the pixel’s response is grey-to-grey, often abbreviated to GtG.
As the name suggests, it’s not a measurement of the time it takes for a single pixel to change in a complete transition from black to off or dark to light.
It’s more of a measure that GtG pixels record the time required to switch between two hues.
The standard VESA method of measuring GtG response doesn’t record the entire time required for this intermediate transition.
It discards the initial 10% and the last 10 percent of the transition and records only the time for the middle 80% of the transition.
What is Input Lag?
“Input Lag” (or screen time lag) is the time lag between the moment your GPU transmits frames to your display and the frame’s display.
This is a crucial component of games, and you want to have a lag of fifteen milliseconds or less recommended.
Display lag or input lag is the amount of time (measured as milliseconds) it takes for a television or monitor to respond and display the commands that you’ve entered using an input device like the keyboard, controller, or mouse.
This also includes all image processing, such as scaling/upconverting, HDR, frame interpolation, deinterlacing, etc.
As you would imagine, the quantity of input delay is crucial in competitive gaming, where every millisecond is critical.
The TV and monitor makers have mentioned the input lag in specifications for the display.
Conducting a thorough study before buying a new screen is highly suggested.😊
Response Time vs Input Lag
The response time is defined as the rate at which pixels shift from one color to another after the frame has been processed.
Input lag is not to be confused with speed of response defined by monitor makers, but not TV manufacturers.
Respond time of OLED on LCD
The most current LCD panels are rated as 1ms for GtG response and 0.5ms for MPRT.
Independent testing suggests an entirely different playbook.
The results for LCD technology are a bit more likely because of the method used.
The ideal case for an ultra-fast-IPS LCD screen like that of the Asus ROG Swift 360Hz PG259QN is about 3ms for a significant portion of the transition, while 6ms is for the entire color shift.
Other tests increase those two figures to 10ms, 6ms, or more. In any case, OLED is faster.
TV vs Monitor (Input Lag)
Because TVs can over-process frames and have a higher input rate than monitors.
Many TVs also have an image preset that is typically referred to as ‘Game Mode’ that bypasses specific images to minimize input lag.
When you’re looking for a television that is used for gaming consoles, it is crucial to verify whether it’s equipped with this feature.
While some models may become more sensitive to input lag than others, the lower the lag is always more suitable.
If you’re searching for a gaming monitor, you shouldn’t have to worry about it because most high-refresh-rate gaming monitors feature very low input lag and a fast response speed.
The input lag won’t be an issue in the absence of gaming because it’s unlikely to detect in normal usage.
How To Reduce Lag Input
If you’re having issues with high latency, be sure to look at the following points before blaming your monitor or television:
- Verify your network connection Ping
- Make sure you’re on TV’s Game Mode
- Verify your monitor’s settings for “Low Input Lag” or similar options.
- Verify that your controller is damaged or has batteries that are not working.
- Avoid cable adapters
- Choose controllers that use cables instead of wireless to reduce in-game lag.
Achieved levels of responsiveness and input time lag
If that’s what the response and lag are all about, What are the exact ranges of latency and responses you require to have a satisfying experience❓
When it comes to OLED television, things are pretty straightforward.
You’ll require a contemporary TV with an actual 120Hz refresh rate and a gaming mode that is low in latency.
There’s currently nothing more efficient in the market. The resolution of such displays is unbeatable and delivers a crystal clear and sharp image.
The blurring will be due to humans’ limited vision. For latency, 4K 120Hz TVs that have OLED are pretty superb.👌🏻
The majority of gamers, they’ll feel fluid and flexible. However, those serious about esports might like something a little more responsive.
This is specifically designed for gaming, and here’s the area where things get tricky.
This is because the quoted specifications aren’t always the best description of the actual experiences of using a gaming monitor.
