HDR Motion Test
Combines moving high-luminance elements with dark backgrounds and color ramps. Measures browser frame timing and pacing while allowing visual motion artifact inspection.
Technical Scope & Limitations
Visual motion inspection. Separates browser frame timing from display panel response characteristics.
Browser rendering output can be influenced by OS display scaling, GPU driver color settings, and active HDR profiles.
Testing Instructions
- Follow the moving bright highlight across the dark field with your eyes.
- Observe trailing halos or color ghosting behind the highlight.
- Review the live FrameTimeMonitor stats to verify browser frame stability.

What This Test Checks
- Motion trailing and color smearing behind bright highlights on deep dark backgrounds.
- Local dimming zone responsiveness during fast highlight movement.
- Real-time browser frame pacing and interval stability.
How to Perform the Test
- Enter fullscreen mode and follow the moving high-luminance object with your eyes.
- Look for dark trailing shadows or bright inverse halos.
- Check the real-time FrameTimeMonitor overlay to verify browser frame consistency.
What to Look For
- Smooth motion with clean edges indicates rapid pixel transitions and stable backlight zone response.
Common Display Problems & Diagnostic Guidance
Zone Response Delay (Trailing Tails)
On some FALD and Mini-LED monitors, backlight zones turn off slower than pixels transition, leaving a glowing trail behind moving highlights.
Frequently Asked Questions
Does this test measure hardware response time?
No. It evaluates visual perceived motion clarity. Physical pixel rise and fall times in milliseconds require external optical photodiode equipment.
