FPS & Frame Performance
Measure real-time frame rates, frame latency, frame pacing stability, and WebGL rendering throughput.
FPS Test
Accurately measure your browser frame rate, average FPS, 1% lows, and instantaneous render stability.
Frame Time Test
Analyze frame duration in milliseconds (e.g. 16.6ms for 60Hz, 6.94ms for 144Hz) and frame time variance.
Frame Pacing Test
Detect frame delivery unevenness, micro-stutters, and presentation queue pacing anomalies.
WebGL FPS Test
Stress test your GPU rendering pipeline with dynamic WebGL geometry, particle simulation, and shader workloads.
Refresh & Motion
Verify display refresh rate (Hz), detect pixel response ghosting, motion blur, and screen tearing.
Refresh Rate Test
Detect and verify your monitor native refresh rate in Hertz (60Hz, 120Hz, 144Hz, 240Hz, 360Hz+).
Ghosting Test
Assess pixel response time, trailing artifacts, inverse ghosting (overshoot), and motion smearing.
Motion Blur Test
Evaluate sample-and-hold display motion blur, persistence, and black-frame insertion (BFI) clarity.
Screen Flicker Test
Expose Pulse-Width Modulation (PWM) backlight flicker and temporal dithering artifacts.
Screen Tearing Test
Expose horizontal frame tearing lines and buffer synchronization mismatches across fast horizontal pans.
Frame Skipping Test
Verify if your monitor overclock or custom resolution is genuinely displaying all frames without dropping cycles.
Display & Screen
Diagnose dead pixels, backlight bleed, color reproduction, gamma curves, and screen uniformity.
Monitor Test
Multi-stage screen assessment covering geometry, color gamut, gradients, text clarity, and contrast.
Screen Test
Rapid multi-step test patterns to verify color rendering, gray steps, viewing angles, and panel defects.
Dead Pixel Test
Identify dead (black), stuck (red/green/blue/white), and defective subpixels across full-screen solid fields.
Backlight Bleed Test
Detect edge backlight leakage, corner IPS glow, and clouding in light-controlled conditions.
Color Test
Verify RGB/CMYK color reproduction, primary chromaticity, and wide color gamut (sRGB, DCI-P3, Rec.2020).
Contrast Test
Evaluate black level depth, white saturation, shadow detail retention, and step gradients.
Gamma Test
Verify display gamma curve (Gamma 1.8, 2.2, 2.4) using alternating subpixel luminance patterns.
HDR Test
Detect HDR display support, wide color gamut headroom, and peak luminance metadata.
Color Banding Test
Detect visible stair-stepping and posterization in subtle color and grayscale gradient ramps.
Screen Uniformity Test
Assess brightness consistency, color temperature balance, and dirty screen effect (DSE) across the panel.
Sharpness Test
Evaluate subpixel text clarity, edge aliasing, scaling halos, and moiré interference patterns.
Complete Screen Test
Automated step-by-step diagnostic workflow running dead pixel, uniformity, color, contrast, and motion tests in sequence.
Screen Information
Detect physical resolution, viewport scaling, aspect ratio, device pixel ratio, and PPI density.
Screen Resolution Test
Detect physical screen resolution, CSS viewport dimensions, device pixel ratio, and color depth.
Screen Size Test
Calculate physical diagonal size (inches/cm), aspect ratio, and viewable surface area.
PPI Test
Calculate exact pixel density (PPI), pixel pitch (mm), total megapixels, and optimal viewing distances.
