What Is a Good Response Time for a Monitor?

What Is Response Time?

Response time is the time a monitor's pixel takes to change from one color or shade to another. It is typically measured in milliseconds (ms). A shorter response time means pixels transition faster, which reduces visual artifacts like ghosting and motion blur in fast-moving scenes.

There are different ways to measure response time, such as gray-to-gray (GTG) and moving picture response time (MPRT). Manufacturers often advertise GTG values, but the actual perceived clarity depends on the panel technology and the refresh rate. For a deeper comparison of how response time interacts with refresh rate, see our refresh rate vs response time article.

Why Response Time Matters

Response time directly affects how smooth and clear fast-moving content appears. If pixels are too slow, moving objects can leave a trail or ghost behind them, which is especially noticeable in fast-paced games and action movies.

NVIDIA's G-SYNC technology addresses some motion issues, as seen in their description of displays that reduce ghosting and artifacts on moving images. However, response time remains a fundamental characteristic of the panel itself. A fast response time is also important for gaming monitors, where every millisecond contributes to a clearer picture during quick camera movements.

How Response Time Is Measured

There is no universal standard for comparing response time numbers across different brands. Gray-to-gray (GTG) response time measures transitions between shades of gray, while MPRT measures how long a pixel is visible, which correlates with motion blur.

For an objective reference, VESA's DisplayHDR specification includes a Rise Time test. It measures how quickly a display transitions from black to maximum luminance: within 8 frames for DisplayHDR 400 and above, and within 2 frames for DisplayHDR True Black certified displays. While this is not a direct gray-to-gray measurement, it provides insight into the display's responsiveness. You can also explore how panel types like IPS, VA, and TN typically differ in response time behavior.

Response Time vs. Refresh Rate

Refresh rate indicates how many times per second the display updates the image, measured in hertz (Hz). A standard monitor works at 60Hz, as noted by ENERGY STAR. Higher refresh rates deliver smoother motion, but if the response time is too slow, the pixel may not finish changing before the next frame arrives, causing blur and reducing the benefit of a high refresh rate.

In practice, you want a response time short enough that the pixel transition is completed within one frame period. However, because measurement methods vary, it is often more useful to read independent reviews or rely on standards like the VESA Rise Time.

What Is a Good Response Time for Your Use Case?

For office work, web browsing, and general productivity, response time is not critical. Even a modestly spec'd panel will look fine for static content and videos. If you are choosing a monitor for home and office, prioritize size, resolution, and ergonomics over raw response time.

For gaming, especially competitive or esports, a faster response time reduces motion blur and ghosting, which can improve tracking moving targets. Consider displays that advertise low response times, but be aware that these numbers may not reflect real-world performance. For a balanced gaming experience, look at 144Hz monitors or 240Hz monitors that also list a low response time.

If you watch movies or use creative applications, response time matters less than color accuracy and contrast, but a slow response time can show artifacts in fast panning shots. If you work with color-critical content, you might also want to learn about color depth and contrast ratio.

• Office and productivity: prioritise size, resolution, and ergonomics; response time is secondary.
• Casual gaming and media: a moderate response time is sufficient; focus on color and contrast.
• Competitive gaming: select a fast response time and pair it with a high refresh rate for the smoothest experience.

How to Choose a Monitor Based on Response Time

Look for monitors that list response time specifications, but treat them as a guideline rather than an absolute truth. Panel types have typical characteristics: TN panels often have very fast response times, while IPS and VA panels vary. To understand these differences, see our panel type comparison guide.

When possible, check for VESA DisplayHDR certification, as it includes a Rise Time requirement. Also consider features like overdrive and variable refresh rate, which can improve motion clarity. Technologies like AMD FreeSync and NVIDIA G-SYNC help reduce tearing and stuttering.

For gaming, pair a fast response time with a high refresh rate for the best experience. Browse our best gaming monitors to see models that balance these factors, or explore IPS monitors if you want a good blend of speed and color.

Questions

What is a good response time for a monitor?

There is no single ideal number because measurement methods vary. For most users, any response time under 10ms is acceptable, but for competitive gaming, faster is better. Look for displays that list response time in their specs, and check independent reviews for real-world performance.

Does a very low response time make a big difference?

A very low response time can reduce ghosting and motion blur in fast scenes, which may improve your ability to track moving objects in games. However, the difference between 1ms and 5ms is often subtle, and other factors like refresh rate and input lag also affect perceived motion clarity.

What is the difference between response time and input lag?

Response time measures how fast a pixel changes color, while input lag measures the delay between an action and the on-screen result. Both affect the overall responsiveness, but they are distinct. A monitor can have a fast response time but still have noticeable input lag, and vice versa. For more, see our input lag article.

Can I improve response time with monitor settings?

Many monitors include an overdrive mode that boosts voltage to make pixel transitions faster. Enabling it can reduce ghosting, but excessive overdrive may cause overshoot artifacts. Experiment with the settings to find the best balance.

Do IPS monitors have bad response times?

Older IPS panels were slower, but modern IPS monitors often achieve response times comparable to TN panels. IPS now offers a good combination of color accuracy and speed, making it suitable for both work and gaming. You can see current IPS models in our best IPS monitors guide.
