The useful part.

Key strengths

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 source
The checks that matter.

Before you buy

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.
