About Response Time Test
Check how fast pixels change color and see if your screen is quick enough for competitive gaming.
Response time is how long a pixel takes to change from one color to another, usually listed in milliseconds as gray to gray or GtG. Fast response keeps moving images sharp, while slow response causes blur and trails. Spec sheets often promise 1ms, but real world speed depends on the panel type, the overdrive setting and the refresh rate.
GtG Vs MPRT
- GtG: the time a pixel takes to switch between shades.
- MPRT: how long each frame stays visible, which drives eye tracking blur.
A good gaming screen needs both: quick GtG to avoid smearing and high refresh or strobing to keep MPRT low.
Typical Response Times
OLED pixels switch almost instantly. Fast IPS panels sit around 1 to 5ms, while many VA panels are slower in dark transitions, which shows up as black smearing. TN panels are fast but have weaker color and viewing angles.
Which App The Install Button Opens
The button opens a related app, Screen Test – Dead Pixel Check on Google Play, whose response time test moves objects at adjustable speeds so you can see ghosting and motion blur on your screen. See trails in detail on our Ghosting Test page.
Key Features
- Moving objects at adjustable speeds
- Shows ghosting and motion blur together
- Extra uniformity, contrast and burn-in tests
- Screen resolution, DPI and refresh rate info
- Lightweight app
