What Is Screen Ghosting (and How Is It Different from Motion Blur?)
Ghosting is a faint trail behind moving objects. It is the most visible panel-quality difference in gaming, and the fix is often a settings change rather than a hardware upgrade.
The mechanics
Liquid crystals take milliseconds to twist from one color to another. If your display shows 144 frames per second but a pixel needs 20 ms to change, the previous frame is still partially visible in the new one — a smear behind anything that moves. Our ghosting test makes this measurable with your eyes: one moving square, dark background, trail visible or not.
Ghosting vs motion blur vs inverse ghosting
Motion blur is the frame-rate limit of the content (a camera or game rendering at 60 fps is blurry by math). Ghosting is the panel being slower than the frames it is fed. Inverse ghosting is the opposite failure: overdrive accelerates pixels so hard they overshoot the target color, leaving bright halos. All three look similar; the test distinguishes them by the trail brightness.
What actually helps
First the settings: enable your monitor response-time/overdrive mode (usually 2–3 levels; middle is almost always right), and confirm the display is running its rated refresh rate. Then the cable: an old HDMI port silently caps many monitors at 60 Hz. A panel upgrade only helps after both of those are ruled out.
Why test before buying
Marketing specs list response time in "GtG" milliseconds measured between gray shades you never see in games. Two panels with identical spec sheets can ghost very differently. A moving-square test on a display in the store — or on arrival, before the return window — tells you more than any spec sheet.
Frequently asked questions
Does ghosting damage the screen?
No — it is response time, not damage.
Is ghosting worse on VA panels?
VA panels typically ghost hardest in dark scenes (black-to-color transitions); IPS is usually more consistent; OLED has essentially none.
