Test result you cannot explain? Defect the guides do not mention? Browser quirk on an unusual screen? Those are the messages that improve the site fastest — write to hello@pixelcheck.app.

Corrections

If a guide states something about panel technology or warranty practice that your experience contradicts, we want to know. Panel engineering changes faster than pages do; confirmed corrections are applied within days, and the guides are reviewed as a set each quarter so a fix in one article does not leave its neighbors stale.

Test requests

The twelve tests here cover the defects that account for most real-world complaints, but the toolbox keeps growing — keyboard and CPU stress tests are on the roadmap. If your hardware problem has no test on this site, describe it: the request queue is ordered by how many people ask, and nothing gets built that cannot be verified with eyes on a real defective panel.

Business inquiries

Advertising and partnership proposals are welcome at the same address — after reading the disclosures page, which explains the revenue model and its limits. Everything else (bugs, accessibility issues, translations) is equally welcome; a testing site that only works on one browser or one language is half a testing site.
