Projection Compass treats a projected image as the result of a system. Optics, screen geometry, ambient light, source format, audio routing and viewing position all interact. A specification sheet describes parts of that system, but it cannot predict every living room. Our articles therefore connect documented capabilities with checks that readers can repeat in a sensible order.
What we cover
The main comparison places five current ultra-short-throw approaches beside one another under the same questions. Separate guides compare furniture and mounting layouts, picture profiles, room profiles and signal routes. The emphasis is practical: establishing a straight image mechanically, identifying the room light that causes the largest loss, separating source problems from cable problems, and preserving a known-good baseline.
These articles are not presented as personal laboratory reviews. Where we have not made an independent measurement, the text clearly identifies a figure as manufacturer information. Suggested settings are starting points, not universal prescriptions. Image size, surface, firmware, source and room remain part of the result.
Source hierarchy
Model-specific statements begin with the latest technical documentation and published specifications from the manufacturer. General explanations use established concepts from video, projection and signal engineering. A secondary source is useful only when it describes a method or observable behaviour that a reader can understand and test.
- current manuals, technical pages and safety information for the model;
- published standards and clearly defined measurement terms;
- repeatable technical principles and diagnostic procedures;
- editorial interpretation with uncertainties stated in plain language.
Terms such as native, dynamic and perceived contrast are not treated as interchangeable. A figure qualified by “up to” is not described as a condition every room will reach. Latency is discussed together with the signal mode and the processing that remains enabled.
Clear language without false certainty
Technical writing should be approachable without erasing limitations. We distinguish between what a device can do, what a manufacturer states, and what can be verified under described conditions. A practical instruction should say what to observe, change one variable at a time and explain how to return to the baseline.
Brand and model names appear only when they identify a necessary example. Search phrases are not hidden or scattered through near-duplicate pages. A manufacturer link supports a technical point; it is not a recommendation and does not alter the editorial weighting.
Independent and non-transactional
Projection Compass has no affiliate links, paid redirects, ranking seals or product enquiry forms. We do not sell products or services. External links lead to official technical documentation, and no commission is attached to a click.
Updates and corrections
Firmware, sources and documentation change. Each main article carries a review date. When a model-specific statement changes, the surrounding passage is checked again rather than replacing one isolated number. A useful correction identifies the page, exact passage, signal format and firmware version.
How the site is delivered
The static build sends the same main text regardless of IP address, location, browser, referrer or advertising parameter. Articles are present in the HTML and do not rely on JavaScript. Scripts operate the mobile navigation, cookie choices and optional language preference only. Fonts and photographs are local; there are no analytics or advertising scripts.
