Is 5ms Response Time Good? What Number You Actually Need
Table of contents
Yes, 5ms response time is good for most people. It is plenty for office work, browsing, films and casual games, especially on a 60Hz or 75Hz monitor. Competitive players on 144Hz or faster screens do benefit from a quicker panel. Keep in mind that the number on the box is usually a best-case figure measured on the fastest overdrive setting, so real-world speed and image quality can differ.
What the response time number means
Response time, usually listed as GtG (gray to gray), is how long a pixel takes to change from one shade to another. Lower is faster. The Wikipedia entry on response time notes that it is usually measured on gray-to-gray transitions between the 10% and 90% points of the change, following a VESA method.
GtG is not the whole motion story. How the monitor pushes pixels to hit that number is covered in our guide on what overdrive is on a monitor, and the blur you see when your eyes track motion is a separate measure explained in our monitor MPRT guide. This article sticks to one practical question: what GtG figure do you actually need?
Refresh rate sets the time budget
The easiest way to judge a response time is to compare it with how long each frame stays on screen. A pixel should finish its change well before the next frame arrives. If it does not, the leftover transition shows as a faint trail behind moving objects.
Frame time is simply 1,000 milliseconds divided by the refresh rate:
- 60Hz: 1,000 / 60 = 16.7ms per frame
- 75Hz: 1,000 / 75 = 13.3ms per frame
- 144Hz: 1,000 / 144 = 6.9ms per frame
- 165Hz: 1,000 / 165 = 6.1ms per frame
- 240Hz: 1,000 / 240 = 4.2ms per frame
At 60Hz, a 5ms panel uses less than a third of each frame, which leaves lots of headroom. At 144Hz, 5ms takes up most of the 6.9ms window, and slower dark transitions can spill over. At 240Hz, a true 5ms average is longer than the 4.2ms frame, so motion will look smeared. That is why the right response time depends on your refresh rate, not on a single magic number. If you are weighing a high refresh monitor, our guide on whether a 165Hz monitor is good for gaming covers the rest of the trade-offs.
Why 1ms GtG is a best-case figure
Manufacturers usually quote the fastest transition they can measure, on the most aggressive overdrive setting. That figure rarely reflects the average across all the color changes in a real game or film. Some transitions, especially between dark shades, can be several times slower than the headline.
The fastest overdrive mode also tends to add overshoot, where a pixel briefly goes past its target shade and leaves a bright or dark halo behind moving objects. Many monitors look best one or two steps below their maximum overdrive level, which means the speed you actually use is slower than the box suggests. Overshoot is easy to confuse with pixel inversion, a separate artifact that shows as a faint flicker or pattern on certain shades.
So treat “1ms GtG” and “1 ms GtG” claims as a sign that a monitor is aimed at gaming, not as a guarantee. A well-tuned panel rated at 4ms or 5ms can look cleaner in motion than a poorly tuned one rated at 1ms. Budget brands such as Titan Army often lead with 1ms figures, so this matters most at lower prices. Independent reviews that measure response times across many transitions are the best guide.
How panel type changes the picture
Panel technology has a bigger effect on real motion than the spec sheet number. In general terms:
OLED
OLED pixels switch almost instantly, so GtG is effectively a non-issue. That speed is one of the selling points behind why OLED is so expensive. Any remaining blur comes from frame persistence and frame rate rather than pixel speed.
Fast IPS
Modern fast IPS panels are quick and consistent across most transitions. With a well-tuned overdrive mode they handle 144Hz and 240Hz gaming comfortably, with good color and viewing angles.
VA
VA panels offer strong contrast and deep blacks, but their dark-level transitions are often slow. That shows up as dark smearing, a shadowy trail behind objects moving across dark scenes and a common form of monitor ghosting. A VA monitor rated at 1ms or 4ms may still smear in dark games.
TN
TN panels are fast and affordable, but colors and viewing angles are weaker. They still appear on some esports-focused monitors.
Response time vs use
| Use | Typical refresh rate | Good response time | Is 5ms good? |
|---|---|---|---|
| Office, browsing, documents | 60Hz to 75Hz | Up to about 8ms | Yes |
| Films, TV and video | 60Hz | Up to about 8ms | Yes |
| Casual and single-player games | 60Hz to 144Hz | About 5ms or faster | Yes |
| Fast competitive shooters | 144Hz to 240Hz | Well-tuned, under 4ms in practice | Borderline |
| Esports at 240Hz and above | 240Hz or more | Fast IPS, TN or OLED | No |
How to choose a response time
Start with your refresh rate and how you play:
- Pick the refresh rate first. It sets how fast the panel has to be, and adaptive sync keeps it smooth when frame rates dip.
- Check the panel type. For dark, fast games, avoid slow VA panels if motion clarity matters most.
- Read measured reviews. Look for average response times and overshoot on the overdrive mode you would actually use.
- Ignore tiny gaps on paper. The difference between a 4ms and 5ms rating rarely decides how a monitor looks.
Response time is not input lag
People often mix up response time and input lag, but they measure different things. Response time is how fast a pixel changes shade once the monitor has drawn a frame. Input lag is the delay between your mouse click or controller press and the result appearing on screen, which includes processing inside the monitor. A 5ms response time does not add 5ms of lag to your aim. A monitor can have fast pixels and still feel sluggish if its processing is slow, which is why some game modes skip image enhancements to cut delay.
What about consoles?
Most console games run at 60 frames per second, with some titles offering 120. At 60, a 5ms panel is comfortably fast enough. At 120, it still keeps up well inside the 8.3ms frame, so a 5ms monitor or TV is a sensible match for console play.
For competitive play, monitor size and refresh rate also matter. Our guides on what size monitor pros use and the best size monitor for gaming cover those choices.
Conclusion
Is 5ms response time good? For office work, video, films and casual games, yes. It fits comfortably inside a 60Hz or 75Hz frame and keeps up with most 144Hz gaming. For fast competitive play at 144Hz to 240Hz, choose a well-tuned fast IPS, TN or OLED panel, and do not trust a 1ms GtG claim on its own.

Frequently asked questions
Is 5ms response time good for gaming?
For casual and single-player gaming at 60Hz or 75Hz, yes. A 5ms panel finishes most transitions well inside a 16.7ms frame. On a 144Hz or 240Hz monitor, each frame is much shorter, so a slower panel can leave visible trails. Competitive players should look for a faster, well-tuned panel.
Is 1ms better than 5ms response time?
On paper, yes, but the gap is smaller than the numbers suggest. Both figures are usually best-case results on the fastest overdrive mode, and that mode often adds overshoot halos. A well-tuned 5ms monitor can look cleaner in motion than a poorly tuned 1ms one, so check independent reviews before buying.
What does 1ms GtG mean?
GtG stands for gray to gray. A 1ms GtG rating means the panel can change a pixel from one shade of gray to another in about one millisecond under the manufacturer's best test conditions. It usually applies to the easiest transitions on the most aggressive overdrive setting, not every color change.
Is 5ms response time good for office work and movies?
Yes. Spreadsheets, browsing, documents and films involve little fast motion, and video typically runs at 24 to 60 frames per second. A 5ms panel easily keeps up with that, so you will not notice any blur or ghosting from the response time in everyday use.
