How to test
01
Set display normally
Use your normal brightness and picture mode.
02
Go full screen
Press F to fill the screen for the clearest view.
03
Start moving pattern
Start Scan and try different speeds and backgrounds.
04
Look behind object
Look just behind the moving object for trails or halos.
How it works & FAQ
What is ghosting?
A faint trail behind a moving object. Pixels take a moment to change color, so the previous position stays faintly visible.
What is inverse ghosting?
A bright or dark halo around the moving object, often from overdrive overshoot. It looks sharper than a soft trail.
What affects ghosting
- Pixel response time
- Overdrive setting
- Refresh rate
- VRR and viewing conditions
This test does not measure pixel response time.
Overdrive reference
Your monitor's Response Time / Overdrive setting changes how aggressively pixels are pushed:
Off
Most ghosting
Default
Normal
Moderate
May reduce trailing
Fast
May show inverse
Fastest
Higher risk of inverse
What is Ghosting Test?
A ghosting test moves a shape across the screen. If you see a faint trail or a light/dark halo behind it, that is ghosting. It happens when pixels are a bit slow to change color.
FAQ
Ghosting Test FAQ
01How do I test my monitor for ghosting?
Run the moving pattern fullscreen and look behind the moving object for a visible trail or smear.
02What does monitor ghosting look like?
Ghosting looks like a faint copy or trail behind a moving object.
03Why does my monitor have ghosting?
Ghosting can be related to pixel response behavior, refresh rate, overdrive settings, or the specific color transition being displayed.
04What is inverse ghosting?
Inverse ghosting can appear as a bright or dark halo around a moving object, often associated with overly aggressive overdrive.
05Can this test measure monitor response time in milliseconds?
No. It is a visual check for motion artifacts, not a laboratory measurement of pixel response time.
06Can I reduce monitor ghosting?
Try different response-time or overdrive settings on the monitor and compare the moving pattern. A setting that is too aggressive can create inverse ghosting.
