About screentest.im

Why we built this

It started with a new monitor unboxing: a huge backlight bleed patch in a dark room, dismissed by the seller with four words — “within normal range”. No standards, no tools, no evidence. Ordinary consumers stand no chance against “normal range”.

So we built screentest.im — a professional-grade screen testing toolkit that runs entirely in your browser, with verdict standards embedded into every step, so “normal range” is never just a slogan again.

Three scenarios we serve

New Device Acceptance

The 7-day return window is short. Finish the 8-step flow 20 minutes after unboxing and return with evidence, not luck.

Second-hand Deals

Test on the spot for 20 minutes and export a report — dead pixels, burn-in and swapped panels exposed for both sides.

Tuning & Calibration

Are esports specs inflated? Is design accuracy on target? Let measurements talk and tune every level to its best.

What makes us different

  • 8-step wizard: progress-tracked tests with verdicts built in
  • Embedded verdicts: every step tells you what to return and what’s normal
  • PDF reports: generated entirely client-side, evidence that settles disputes
  • Chinese-first: default Simplified Chinese UI with a full English mirror
