Display Tests
Dead Pixel Test
Inspect solid fullscreen colors and document pixels that appear dark, bright, or fixed. This visual check does not automatically classify defects or warranty eligibility.
Touch Screen Test
Trace a fullscreen grid to check which areas report touch or pointer input. The test runs in your browser without storing coordinates or automatically declaring a hardware defect.
Frame Skipping Test
Photograph an automatically advancing numbered pattern to look for repeated gaps. Browser timing only prepares the pattern; it does not certify the display refresh path.
Uniformity Test
Visually compare relative brightness and color consistency across neutral gray and solid-color patterns. This browser test does not calculate calibrated uniformity.
Gamma Test
Check your monitor's gamma behavior with browser-based patterns. Use the result as a visual reference, not a lab measurement.
Black and White Detail Check
Inspect black and white clipping, shadow and highlight detail, and gradient separation. Browser patterns cannot produce a calibrated contrast-ratio value.
Response Time Test
Use browser motion patterns to inspect visible ghosting, overshoot, and motion clarity. This visual check does not produce a panel response-time rating in milliseconds.
Refresh Rate Test
Record requestAnimationFrame cadence and frame pacing while this browser tab stays visible. The result is browser timing data, not panel certification.
Burn-in Test
Use solid colors and moving patterns to inspect retention-like artifacts on OLED and other displays. A browser observation cannot prove that an artifact is permanent burn-in.
Color Temperature Test
Compare one Night light or picture-setting change on the same white reference, restore the original setting, and save what changed. No physical Kelvin value is measured.
Backlight Bleed Test
Observe a dark fullscreen pattern for edge light leaks or IPS glow under controlled room conditions. Camera exposure can exaggerate what the eye sees.
Gradient Banding Test
Inspect browser-rendered gradients for visible color bands across several colors and directions. Visible bands cannot prove whether a panel is 8-bit or 10-bit.
HDR Capability Check
Check browser HDR and color-gamut capability signals, follow up in display settings, and optionally compare SDR patterns. This page does not generate HDR content.
Flicker Test
Compare camera-visible bands or pulsing across display brightness settings and browser patterns. This check cannot measure PWM frequency or determine medical safety.
Browser Reaction Time Check
Understand browser reaction timing across the human, input-device, browser, operating-system, and display path. It cannot isolate monitor input lag.
Viewing Angle Test
Inspect visible color, brightness, and contrast changes from centered and off-axis positions. This visual test cannot identify panel technology.
Screen Info
View browser-reported CSS dimensions, pixel ratio, and capability signals. Calculate PPI separately from the panel diagonal and native pixel dimensions you enter.
Viewing Distance Calculator
Calculate distance from screen diagonal, resolution aspect ratio, and a chosen horizontal viewing angle. Compare your measured desk position with transparent geometry and a worked example.
Text Clarity Test
Compare subjective readability, fringing, and stroke appearance across browser-rendered text samples. The page cannot certify subpixel layout or a universal grade.
Multi-Screen Alignment
Use browser patterns to compare visible alignment and relative color across two or more displays. Save your own observations locally; this is not calibrated matching.
