How to read this comparison
Manufacturer facts for the exact models shown. Not a quality rating or a test result.
“Different” means the known values differ, not that one is better.
Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

Match the screen, lens and room. Check the stated throw ratio, lens setup and connections. ANSI, ISO, LED and centre-lumen claims keep their different measurement bases; they are not an overall picture-quality score. A projected 4K claim does not by itself identify the physical imager pixel grid. Accepted input modes remain separate.

What it brings
The manufacturer supplies model-specific projection, placement and connection specifications. Use the stated throw ratio, actual image size and lens configuration to plan your installation.
Manufacturer image and brightness claims are not an independent picture-quality test. Physical imager pixels, input limits, measurement methods, bundled TV devices and regional accessories need their own stated source scope; no overall winner or current stock is established.
