The "1ms" printed on a gaming monitor box is usually one selected pixel transition, one overdrive setting or a motion-blur mode under controlled conditions. Your game contains many colours and refresh rates. Some transitions finish quickly; others leave a trail. The useful monitor response time is the behaviour across that whole range.
Quick Answer
Treat 1ms as a prompt to read a proper response test, not a final comparison. Look for average grey-to-grey transition time, overshoot and performance at several refresh rates. GtG measures how quickly pixels change between shades. MPRT describes visible motion persistence and is often tied to a backlight-strobing mode. A monitor needs response fast enough for its refresh interval without creating inverse ghosting. Evetech's July 2026 gaming-monitor midpoint was R4,499, a dated local price marker before you compare the measured implementations behind similar claims.
🩶 Understand grey-to-grey without worshipping the best transition
GtG testing times changes between grey levels because real pixels rarely move simply from full black to full white. A review may measure many transitions and report an average, fastest, slowest and overshoot.
A 1ms best case can sit beside several much slower dark transitions. Those slow changes appear as smearing behind dark objects, especially on some high-contrast LCD panels. The average and distribution tell the fuller story.
At 144Hz, each refresh interval is about 6.9ms. At 240Hz, it is roughly 4.2ms. Pixels that take longer than the interval can carry the old image into the next refresh.
Browse Evetech's monitor range by refresh rate, then look for measured response on the shortlisted models.
💥 Watch overdrive create a different problem
Overdrive pushes pixels harder so they reach the target sooner. Too little creates ghosting; too much overshoots the target and leaves a bright or dark inverse trail.
The fastest menu setting often produces the advertised 1ms result while looking poor in motion. Use a middle setting that stays clean across the VRR range. Some monitors have excellent variable overdrive; others need one setting for high refresh and another for 60Hz games.
📷 Separate MPRT from GtG
MPRT describes how long a moving image remains visible to your eyes. LCD backlight strobing can shorten that visible persistence by inserting dark periods, creating clearer motion even though the physical pixel transition has not become equally fast.
Strobing can reduce brightness, create double images when frame rate and refresh do not match, and often disables VRR. A 1ms MPRT claim may therefore describe a special mode you never use.
🧪 Run a moving-object check at your real refresh
Open a familiar game and pan across dark edges, fine text and high-contrast objects. Try the monitor's overdrive options at the refresh rates you normally visit. Look for a soft dark trail, a bright halo or texture detail disappearing during motion.
Keep VRR active for the mixed-rate test. A setting that looks clean at maximum refresh may overshoot when a heavy game falls to 90fps. Choose the mode that requires the least intervention through the session.
A pursuit-camera review can reveal trails more clearly than a phone held still in front of the screen. Your eyes remain the final judge: sit at the usual distance and test the pan speed that appears in your games.
Evetech's monitor best-sellers turn the test into a current local shortlist after refresh and panel type are chosen.
🖥️ Put panel type in context
OLED pixels switch extremely quickly and usually show little transition blur. TN can deliver fast competitive response with narrower viewing and colour trade-offs. Modern IPS spans a wide range from excellent to ordinary, while high-contrast VA designs can show slower dark transitions.
These are tendencies, not model verdicts. Electronics and tuning decide whether a specific monitor uses its panel well.
Also check whether enabling a low-latency or strobing feature locks brightness, VRR or overdrive. The fastest laboratory mode may remove a feature you rely on every night.
Frequently Asked Questions
What does grey-to-grey response time measure?
It times pixel transitions between selected grey levels, usually across many shade combinations in a thorough test.
Why can a 1ms monitor still show ghosting?
The claim may use the fastest transition or an aggressive mode while other transitions remain slower.
What is MPRT and how does it differ from GtG?
MPRT describes visible motion persistence. GtG times physical shade transitions. Backlight strobing can improve one without matching the other.
Does overdrive setting affect response time?
Yes. It speeds transitions, but an excessive setting creates overshoot and inverse ghosting.
Is IPS or TN faster for real-world response time?
Fast examples exist in both. TN often targets competition, while modern IPS can combine strong response with better viewing quality.
Does response time matter more than refresh rate?
They work together. Refresh creates opportunities for new images; response determines whether pixels complete those changes cleanly.
Can a slow response time monitor still be fine for work?
Yes. Static productivity is less sensitive, although scrolling and video can still reveal blur.
