Dead Pixel Test, Without the Video Fuzz

Why it surfaced

Dead Pixel Test treats a monitor check as more than a coloured rectangle: it serves exact sRGB fills, runs 13 display tests, and builds a fault report. The site also makes a persuasive privacy gesture—no ads, no tracking, no account, and an offline-capable suite for testing hardware before it joins a network.

A browser-based screen diagnostic that checks pixels, panel uniformity, motion, timing, scaling, and other display faults.
