Display Attribute That Reduces Motion Blur in Gaming
Which of the following display attributes is crucial for reducing motion blur in fast-paced video or gaming content?
Community Insight
The question tests your ability to separate pixel-transition speed (response time) from frame-update frequency (refresh rate), and the trap is picking refresh rate because it sounds more 'gaming' oriented.
This Core 1 exam question asks which display attribute most directly reduces motion blur in fast-paced video and gaming. The correct attribute is response time, because it measures how quickly each pixel can switch colors and therefore how much ghosting trails moving objects.
Option B (refresh rate) is the most common wrong pick: learners associate high refresh rates like 144 Hz with gaming smoothness, but refresh rate governs how often frames are displayed, not how cleanly pixels finish transitioning, which is what causes visible smearing.

Why the Answer Is Correct
Response time is measured in milliseconds and describes how fast a pixel can change from one shade to another. When a pixel lags behind the new frame, the previous image lingers at the edges of moving objects, producing the trailing known as ghosting or motion blur. Shortening that transition directly removes the smear in fast-panning scenes and rapid crosshair movement, which is exactly what the question asks about. This is why gaming monitors advertise 1 ms or 4 ms response times alongside their gaming credentials.Why the Other Options Are Wrong
Refresh rate (B) does matter for fast content, but it determines how many distinct frames are shown per second and primarily affects smoothness and input latency, not the pixel-level trailing that characterizes motion blur. Resolution (C) governs pixel density and image detail, and higher resolution can actually make trailing artifacts more visible rather than reducing them. Color accuracy (D) concerns how faithfully hues and grayscale values are reproduced, which has no bearing on how quickly the panel transitions between frames.Community Comment Notes
The comments split evenly on this question. One commenter argued for A, explaining that slow pixels "leave trailing artifacts behind moving objects" that are recognized as ghosting or motion blur. Another went the other way, asserting that a "Higher refresh rate shows the screen more times each second, helping fast motion look smoother" — which addresses smoothness rather than blur, so the response-time reasoning remains the stronger match to the wording.Exam Strategy
Read carefully whether the stem says 'smoother motion' or 'reduced blur': smoothness points to refresh rate, while trailing, ghosting, and blur point to response time. On Core 1 display questions, tie each attribute to its own symptom — pixels changing color = response time, frames shown per second = refresh rate.
Frequently Asked Questions
Why isn't refresh rate the answer if gaming monitors advertise 144 Hz?
Refresh rate controls how many frames appear each second, improving smoothness and responsiveness. Motion blur itself comes from pixels taking too long to finish changing color, which is response time.
Does response time matter for regular video playback too?
Yes. Slow response times create visible smearing behind pans and fast action in movies, not just games. Lower millisecond ratings keep edges crisp during quick scene movement.
