Watch for trails behind the moving shapes.
Monitor ghosting test
Run a free online ghosting test for your monitor or TV. Moving blocks, scrolling text, and lines show screen ghosting and motion blur — then use the overdrive guide to clean up trails.

Panel response
Typical GtG — shorter is faster
- OLED <0.1ms
- TN 1–4ms
- IPS 3–8ms
- VA 5–40ms
How to use this
Marketing “1ms” claims are often optimistic. Trust what you see in the preview: VA usually trails more on dark backgrounds; IPS is cleaner but can show bright halos if overdrive is maxed. OLED should look nearly trail-free.
Monitor overdrive
Change this in your monitor’s menu (Response Time / OD / Overdrive) while you watch the preview — it is not a setting on this website.
- Off Slowest pixels — most trailing Default
- Normal Usually the cleanest start Try first
- Fast May add bright edge halos Caution
- Fastest Often looks worse — inverse ghosting Avoid
What you should see
Look at the moving shapes in the preview
Good — little or no ghosting
Block edges stay sharp. You do not see a blurry trail or a bright outline following the motion.
Ghosting — needs a fix
A soft smear behind the block = pixels too slow. A bright halo around the edge = overdrive set too high. Open your monitor menu and try Normal, then recheck.
Free screen & display ghosting test
A browser monitor ghosting test with UFO-style motion patterns: block tracking, text scroll, and line pans — plus inverse ghosting cues and OSD overdrive tips beside the preview.
UFO-style motion patterns
Block tracking mimics classic UFO ghosting test object trails. Text and line modes add fine-edge and pan smear checks without a separate download.
Monitor & screen presets
Slow, medium, and fast speeds with black, grey, and white backgrounds — the same contrasts people use in a display ghosting test for dark-scene VA smear.
Inverse ghosting guidance
Bright edge halos usually mean overdrive is too high. The monitor overdrive card maps Off → Fastest so you know what to change in the OSD.
What a monitor ghosting test shows
Screen ghosting is a soft trail behind motion. Inverse ghosting is a bright corona from aggressive overdrive — both show up clearly on a flat moving pattern.
Screen ghosting (smear)
Pixels take milliseconds to change shade. Behind a moving block you see a blurry wake — classic monitor ghosting, common on slower VA panels in dark scenes.
Inverse ghosting
Overdrive overshoots the target color, leaving bright outlines or inverted trails. If edges look electric, lower Response Time / OD one step and retest.
Motion blur vs refresh rate
High Hz redraws more often, but slow pixels still smear. Pair this display ghosting test with a refresh rate check so muddy motion is not blamed on Hz alone.
How to test ghosting on a monitor
About two minutes: fullscreen this ghosting test, stress Fast speed, then adjust monitor overdrive until trails and inverse ghosting settle.
-
Start the online ghosting test
Open this page in a focused tab and fullscreen the motion stage. Watch Block Tracking first — trails behind the squares are the clearest screen ghosting signal, similar to a UFO ghosting test chase pattern. See also: refresh rate test .
Tip Keep the tab focused so animation stays smooth
-
Stress speed and background
Raise speed to Fast, then flip Black / Grey / White. Dark grey often reveals VA monitor ghosting; white can expose inverse ghosting from overdrive set too high. See also: panel response ranges .
Tip If Slow looks fine but Fast smears, response time is the bottleneck
-
Fix trails in the monitor menu
Open Response Time / Overdrive / OD on the monitor. Start at Normal. Soft smear → nudge up; bright halos → step down. Confirm with Text Scroll for fine edges. See also: full ghosting guide .
Tip Fastest OD often looks worse than Normal on many IPS panels
Panel response ranges (typical)
OLED
Near-instant pixel switching. Display ghosting is rare; judge motion clarity and any TV processing blur instead.
TN
Historically very fast grey-to-grey. Often clean in a ghosting test monitor check, with weaker viewing angles than IPS.
IPS
Modern gaming IPS usually tracks cleanly at Medium–Fast. Aggressive OD is the usual source of inverse ghosting.
VA
Deep blacks, slower dark transitions. Expect more screen ghosting on black/grey backgrounds — this pattern is built to show it.
When a screen ghosting test matters
Competitive FPS
- Trails on crosshairs and enemy outlines hurt tracking clarity.
- Prefer clean Normal OD over max OD with inverse ghosting.
- Confirm Hz is actually active after you clean up response.
Sports & scrolling UI
- Horizontal pans and ticker text expose smear quickly.
- Text Scroll mode mimics UI and scoreboard edges.
- Grey backgrounds often match broadcast-style scenes.
Buying / returns
- Compare panels side by side with the same Fast preset.
- Note OD setting used so store demos stay fair.
- Clip a short video of the ghosting test if you need evidence.
Office & media
- Mild smear is less critical for documents and video.
- Still worth a quick display ghosting test if scrolling feels muddy.
- Default OD is usually enough for desk use.
Monitor ghosting test FAQs
How do I test ghosting on a monitor?
Open this free monitor ghosting test, fullscreen the preview, watch Block Tracking at Fast speed, then try Black/Grey/White backgrounds. Soft trails mean slow pixels; bright halos mean overdrive is too high — adjust Response Time / OD in the monitor menu.
Is this the same as a UFO ghosting test?
Same idea as a UFO ghosting test / TestUFO-style motion check — moving shapes to judge blur — but this runs in your browser with block, text, and line modes plus overdrive guidance next to the preview. No separate download.
What is a screen ghosting test?
A screen (or display) ghosting test fills the panel with moving patterns so you can see trailing behind objects. It is for monitors and TVs — not the same as a keyboard ghosting / anti-ghosting key-rollover test.
What is inverse ghosting?
Inverse ghosting is a bright outline or inverted trail caused by overdrive set too high. Drop OD one step and re-run this ghosting test monitor check.
What response time is “good”?
Marketing ms numbers are optimistic. Visually, clean edges at Fast speed with Normal overdrive is the practical bar. Budget VA often shows screen ghosting on dark backgrounds even when the sticker says 1ms.
Does higher refresh fix ghosting?
Not by itself. Higher Hz updates more often, but slow pixels still leave trails. Fix response/overdrive with this online ghosting test, then confirm Hz with the refresh rate test.
How do I test a monitor for ghosting before keeping it?
Run this page fullscreen at Fast + Grey, compare with the store’s demo settings noted, and photograph or record any fixed trails. Pair with white/black pixel checks if you also care about dead pixels.
Can browsers fake response time?
The animation is GPU/compositor driven; the smear you see is from the panel (and sometimes display processing). Keep the tab focused and avoid remote desktop for honest results.
Tips for a clearer monitor ghosting test
-
Set max refresh first
In Windows Advanced display (or macOS Displays), lock the panel to its highest Hz before judging smear.
-
Use a direct cable
Docks and cheap HDMI adapters can cap refresh. Prefer DisplayPort or a known-good HDMI 2.0+ link for gaming monitors.
-
Disable extra sharpening
GPU sharpening and some TV motion modes invent edges. Turn them off so you judge the panel, not post-processing.
-
Verify after OD changes
Change one OSD option at a time, then recheck Block Tracking and Text Scroll at Fast speed.
