Monitor Ghosting & Motion Blur Test

Inspect pixel response times, trailing motion blur, and monitor overdrive overshoot (inverse ghosting coronas) with high-speed moving UFO animation lanes.

How to Read Motion Artifacts

Normal Motion Blur:

A soft trailing smear following the UFO is normal for LCD/IPS panels due to sample-and-hold display technology.

Inverse Ghosting (Overshoot):

A bright white or dark halo preceding or following the UFO indicates monitor overdrive is set too aggressively (e.g. Extreme / Fastest). Lower overdrive in monitor OSD.

OLED / 240Hz Clarity:

High refresh rate OLED displays (0.03ms GtG) show near-zero trailing with exceptional clarity on the UFO eyes and legs.

Monitor Ghosting & Motion Blur Guide

How to Use This Test

  1. Watch the UFOs moving across the three background lanes. Follow the middle UFO horizontally with your eyes.
  2. Look at the trail behind the UFO: a blurry, smeared tail indicates Ghosting (slow pixel response).
  3. If you notice a glowing white or dark halo around the UFO, your monitor is exhibiting Inverse Ghosting (Overshoot).
  4. Use your physical monitor's menu buttons (OSD) to adjust your Overdrive / Response Time setting (e.g. Off, Normal, Fast, Extreme) until motion is sharpest.

What Causes Ghosting on LCD Monitors?

In LCD monitors (IPS, VA, TN), liquid crystal molecules take physical time to twist and change color (measured as Gray-to-Gray or GtG response time). If the pixels cannot transition to their new color before the next screen refresh, you see a trailing smear or "ghost" image behind moving objects.

How to Fix Inverse Ghosting (Overshoot)

Monitors use a feature called Overdrive (or TraceFree / AMA) to boost voltage and make pixels change faster. However, setting Overdrive to its maximum level (like "Extreme" or "Fastest") pushes pixels past their target color, creating bright glowing halos. Lowering Overdrive to "Normal" or "Medium" usually produces the cleanest picture.

VA vs. IPS vs. OLED Motion Performance

VA panels offer deep contrast but often show noticeable "black smearing" when dark objects move across dark backgrounds. IPS panels offer good all-around speed with minimal trailing. OLED displays have near-instantaneous pixel response times (~0.03 ms), virtually eliminating ghosting trails.
