Accurately measure your browser frame rate, average FPS, 1% lows, and instantaneous render stability.

Detect and verify your monitor native refresh rate in Hertz (60Hz, 120Hz, 144Hz, 240Hz, 360Hz+).

Multi-stage screen assessment covering geometry, color gamut, gradients, text clarity, and contrast.

Rapid multi-step test patterns to verify color rendering, gray steps, viewing angles, and panel defects.

Identify dead (black), stuck (red/green/blue/white), and defective subpixels across full-screen solid fields.

Assess pixel response time, trailing artifacts, inverse ghosting (overshoot), and motion smearing.

Evaluate sample-and-hold display motion blur, persistence, and black-frame insertion (BFI) clarity.

Detect edge backlight leakage, corner IPS glow, and clouding in light-controlled conditions.

Detect physical screen resolution, CSS viewport dimensions, device pixel ratio, and color depth.

Calculate physical diagonal size (inches/cm), aspect ratio, and viewable surface area.

Verify RGB/CMYK color reproduction, primary chromaticity, and wide color gamut (sRGB, DCI-P3, Rec.2020).

Evaluate black level depth, white saturation, shadow detail retention, and step gradients.

Verify display gamma curve (Gamma 1.8, 2.2, 2.4) using alternating subpixel luminance patterns.

Expose Pulse-Width Modulation (PWM) backlight flicker and temporal dithering artifacts.

Analyze frame duration in milliseconds (e.g. 16.6ms for 60Hz, 6.94ms for 144Hz) and frame time variance.

Detect frame delivery unevenness, micro-stutters, and presentation queue pacing anomalies.

Expose horizontal frame tearing lines and buffer synchronization mismatches across fast horizontal pans.

Verify if your monitor overclock or custom resolution is genuinely displaying all frames without dropping cycles.

Detect HDR display support, wide color gamut headroom, and peak luminance metadata.

Detect visible stair-stepping and posterization in subtle color and grayscale gradient ramps.

Assess brightness consistency, color temperature balance, and dirty screen effect (DSE) across the panel.

Evaluate subpixel text clarity, edge aliasing, scaling halos, and moiré interference patterns.

Calculate exact pixel density (PPI), pixel pitch (mm), total megapixels, and optimal viewing distances.

Stress test your GPU rendering pipeline with dynamic WebGL geometry, particle simulation, and shader workloads.

Automated step-by-step diagnostic workflow running dead pixel, uniformity, color, contrast, and motion tests in sequence.
