Pontos Principais
- A taxa de atualização (Hz) é o número de quadros desenhados por segundo; taxas maiores reduzem o desfoque e o atraso de entrada.
- A detecção no navegador calcula intervalos de tempo precisos entre chamadas consecutivas de requestAnimationFrame.
- O teste UFO evidencia o impacto do tempo de resposta de pixel (GtG) e da persistência visual na clareza.
- Telas inteiras em cores primárias (RGB) facilitam a localização de pixels mortos (pretos) ou travados (coloridos).

01.Refresh Rate (Hz) vs. Frame Rate (FPS) Explained
Refresh rate (measured in Hertz) is a physical hardware capability of the display panel (e.g., 60Hz, 144Hz, 240Hz, 360Hz). Frame rate (Frames Per Second - FPS) is the rate at which your GPU renders new frames. When FPS matches or exceeds display Hz with variable refresh rate technologies (G-Sync / FreeSync), motion fluidity is maximized and screen tearing is eliminated.
02.UFO Pursuit Motion Blur & Pixel Response Times
Sample-and-hold display technology retains image frames until the next refresh cycle. The UFO test moves graphical elements across the screen at varying speeds (e.g., 60 FPS, 120 FPS, 240 FPS), making ghosting trails, inverse ghosting (overshoot caused by aggressive overdrive), and motion blur clearly visible to the human eye.
How to Test Display Refresh Rate and Pixels
Step-by-step display diagnostic workflow.
1
Open Screen Tester
Navigate to the Screen Refresh Rate tool in a modern browser (Chrome, Edge, Firefox, Safari).
2
Check Real-Time Hz
Observe the real-time measured Hz counter to confirm your display is operating at its maximum rated frequency.
3
Evaluate Motion Blur
Follow the moving UFO sprites across different speed tiers to inspect ghosting and motion clarity.
4
Run Full-Screen Dead Pixel Test
Click full-screen RGB color blocks (Red, Green, Blue, White, Black) to inspect for dead or stuck pixels.
Frequently Asked Questions
Check your OS display settings (Windows Settings > Display > Advanced display) to ensure the refresh rate is set to 144Hz, and verify you are using a DisplayPort or HDMI 2.0+ cable.
