Do you repair monitors?

No—we provide online tools only.

Include detailed notice per terms page instructions.

Yes—describe use case and who benefits.

Contato em português?

You may write in Portuguese; we aim to respond in the same language when possible.

Email or form only unless a number is published here by the owner.

Reach out if a tool fails in your browser, a translation reads awkwardly in pt-BR, or you want to suggest a new fullscreen utility.

Include device model, browser version, and URL slug when reporting bugs so we can reproduce fullscreen or color issues.

We cannot diagnose hardware defects by email—use guides and warranty channels for panel replacements.

Bug reports: steps to reproduce, expected vs actual behavior, screenshots if UI is visible outside fullscreen.

Small teams may reply within several business days. Urgent hardware problems should go to manufacturer support.

Media kits and sponsorship inquiries are welcome with context about audience and timeline.

Do not send passwords or payment data. See privacy policy for how messages are stored.

Brazilian Portuguese corrections are appreciated—note slug and suggested wording.

Check FAQ first for fullscreen shortcuts and common pixel test questions.
