UFO Motion Blur & Ghosting Test
Evaluate pixel transition response times (GtG), trailing ghost artifacts, inverse ghosting overshoot (coronas), and motion clarity at 60Hz, 120Hz, 144Hz, 240Hz+.
Ghosting (Slow GtG)
A dark or blurry shadow trailing behind the moving spacecraft indicates slow Gray-to-Gray pixel transition response time.
Inverse Ghosting (Overshoot)
A bright glowing halo or inverted outline in front of the UFO indicates overly aggressive monitor overdrive settings.
OLED Instant Response
OLED panels exhibit near-instant 0.03ms pixel response times, producing razor-sharp motion contours with zero phosphor smearing.
How to Adjust Monitor Overdrive Settings
- If you see trailing blur (Ghosting): Increase your monitor's "Overdrive" or "Response Time" setting from Normal to Fast.
- If you see bright halos (Inverse Ghosting): Your overdrive is set too high (e.g. Extreme). Lower it to Fast or Normal to remove voltage overshoot.
- Check Refresh Rate: Make sure your OS display settings are set to your monitor's maximum native refresh rate (144Hz, 165Hz, 240Hz, or 360Hz).
Live Display & Monitor Diagnostics
Accurate hardware data detected directly from your connected display, GPU pipeline, and browser window.
Pre-Built Screen Test Modules
Run dedicated hardware-level automated test patterns to diagnose panel defects, calibration anomalies, response times, and subpixel clarity.
Dead & Stuck Pixel Scanner
Automatically cycles through high-contrast primary RGB and CMY solid colors to easily spot permanently dead (black) or stuck (single color) subpixels.
Backlight Bleed & IPS Glow
Presents a 100% pure black field with subtle corner and edge quadrant markers to inspect light leakage on IPS, VA, and edge-lit LED displays.
OLED Burn-in & Ghosting
High-frequency rapid color cycling and noise dithering to unstick stubborn pixels, test for image retention, and exercise OLED phosphors.
Color Uniformity & Banding
Renders ultra-smooth horizontal/vertical color ramps and grayscale steps to diagnose color stepping, banding, and dirty screen effect (DSE).
Contrast & Gamma Matrix
32-step shadow detail (0%–15% IRE) and highlight blocks (85%–100% IRE) to detect crushed shadow blacks and clipped highlight whites.
Motion Blur & UFO Refresh Rate
High-speed animated UFO objects moving at pixel-synchronized velocities with real-time FPS/Hz detection to test display ghosting and MPRT.
Text & Subpixel Clarity
High-density 1-pixel micro-grids and font rendering tests across varied point sizes to check ClearType antialiasing and RGB/BGR subpixel layouts.
Ambient Ring Light & Glow
Transforms your monitor into a soft studio ring light or warm ambient glow for Zoom video calls, streaming, and soft night desk lighting.
