Tes Waktu Respons Piksel

Why Should You Run This Test?

If you see ghosting, motion blur, or trailing shadows behind fast-moving objects in games or videos, your monitor's pixel response time may be too slow. This test rapidly flashes between black and white so you can observe how quickly your pixels transition.

Common Symptoms

• Ghost trails behind moving text when scrolling web pages
• Motion blur during fast-paced games (FPS, racing)
• Smearing or "black smear" in dark scenes (common on VA panels)
• Mouse cursor leaves a visible trail when moved quickly

What Causes Slow Pixel Response?

Panel Technology

• VA panels (8-15ms) — VA panels have the slowest response, especially in dark-to-light transitions. "Black smear" is a known VA issue where dark pixels trail noticeably.
• IPS panels (4-5ms) — Good balance between response time and color accuracy. Some affordable IPS monitors have slower transitions.
• TN panels (1-2ms) — Fastest LCD response time but worst viewing angles and colors.
• OLED (0.1ms) — Near-instant response with no ghosting, but susceptible to burn-in.

Other Factors

• Overdrive set too high — Monitor overdrive/response time settings that are too aggressive cause "inverse ghosting" (bright corona artifacts).
• Low refresh rate — 60Hz shows more perceived blur than 144Hz even with the same response time.
• VSync or frame buffering — These add input lag that can feel like slow response.

How to Read Your Results

How to Reduce Ghosting

• Adjust monitor overdrive — Most gaming monitors have an "Overdrive" or "Response Time" setting in the OSD (Off/Low/Medium/High). Start at Medium — too high causes inverse ghosting.
• Increase refresh rate — If your monitor supports 120Hz/144Hz, enable it in Display Settings. Higher refresh rate reduces perceived motion blur.
• Enable motion blur reduction — Some monitors have backlight strobing features (ULMB, ELMB, DyAc) that reduce perceived motion blur at the cost of brightness.
• Disable frame buffering — Turn off VSync, triple buffering, or other frame smoothing that adds latency.
• Consider panel upgrade — If ghosting is severe and persistent, your panel type (VA) may be the limitation. IPS or OLED panels offer faster transitions.
