Test Your Display Down To The Smallest Detail

Push your screen to its Absolute limits with our suite of 16 scientifically designed, browser-based professional testing tools.

Hardware Refresh Rate: Calculating...

1. Defect & Artifact Tests

Dead & Stuck Pixel Test

Cycle pure colors to locate permanently dark, glowing, or stuck RGB sub-pixels.

IPS Glow / Light Bleed

Output true black. Check for uneven lighting or 'glowing' seeping from panel corners in a dark room.

OLED Burn-in & Retention

Use 50% gray and deep red screens to spot ghosted UI elements (taskbars/HUDs) permanently etched into your OLED.

Screen Tearing (V-Sync)

Simulate rapid horizontal movement to expose tearing lines if your G-Sync/FreeSync/V-Sync is broken.

Panel Uniformity / Dirty Screen

Test for the "Dirty Screen Effect" (DSE). Colors should look identically bright from corner to corner.

Stuck Pixel Fixer Tool

Forces a localized strobe at 60Hz. It has a chance to revive stubbornly stuck (not dead) sub-pixels.

2. Calibration & Gamut Tests

Gamma Calibration (2.2)

Verify if your display is accurately targeting a 2.2 Gamma curve using visual blend blocks to ensure correct brightness.

Black Saturation (Black Crush)

Check if you can distinguish RGB 1 from RGB 0. Critical for dark movie scenes and horror games.

White Saturation (Blooming)

Check if extreme RGB 254 details are blooming into pure white, causing you to lose highlight detail.

Color Banding (8-Bit / 10-Bit)

Check for smooth color gradations without distinct stepped 'bands' to evaluate your panel's bit depth.

Color Distance / Contrast Ratio

Evaluate exact color separation thresholds between distinct hue values on the sRGB spectrum.

3. Motion & Sub-pixel Rendering

UFO Ghosting & Overdrive

Track fast-moving UFO objects. Test your overdrive setting; too low causes smearing, too high causes inverse halos.

Response Time / Input Lag Demo

Test the visually perceived delay between an instant click action and the pixel color changing on screen.

Viewing Angle Washout (TN/VA/IPS)

View geometric patterns from sharp off-center angles to identify extreme color wash-out specific to your panel type.

Sub-Pixel Rendering & Text Clarity

Micro-text and 1px lines help identify anti-aliasing issues caused by non-standard RGB sub-pixel layouts like BGR.

Pixel Inversion / Moire Flicker

Examine tight checkerboards to see if screen flickering occurs due to LCD voltage inversion cycles.
