How the Automated Display Audit Works
Standardized 8-point hardware audit protocol designed for monitor returns, refurbished hardware inspection, and display calibration.
The audit automatically advances through 8 standardized benchmarks: dead subpixels, backlight bleed, 256-step contrast, gamma 2.2, 1px high-frequency sharpness, live hardware refresh rate (Hz), color gradients, and UFO motion blur.
As each test runs on the live stage, you can click Pass or Issue Found. If you take no action, the runner auto-validates normal response and transitions seamlessly to the next benchmark.
Press F anytime during the audit to expand the stage to 100% of your physical monitor screen, hiding all browser and OS toolbars for pixel-perfect inspection.
Upon completion, the system generates an official Display Health Certificate with Grade (A+, B, C), verified pass/fail checklist items, detected hardware specifications, and an exportable PDF/Printable summary.
