Screen Signal's editorial rule is simple: do not turn marketing claims into independent facts.
Source hierarchy
- Manufacturer or official product documentation for current published specifications.
- Specialist retailers when a manufacturer page does not expose a needed size/spec detail.
- Independent hands-on reviewers for measured behavior, always attributed to the reviewer.
Experience claims
We do not write “we tested,” “we found” or similar firsthand language unless Screen Signal actually conducted the test. Launch content on this site does not claim first-hand lab testing.
Comparisons
Comparison pages use stable product characteristics such as gain, viewing angle, optical approach, size range, throw compatibility and hardware format. Prices are treated as volatile and are dated or routed to the merchant for live verification.
Corrections and updates
Projector-screen products change. When specifications or availability shift, pages should be updated in place when the search intent remains the same instead of creating duplicate thin pages.
