Sources & methodology
Screen outlines use the manufacturer’s measured diagonal and aspect ratio when published, otherwise nominal size. Screen area uses nominal 16:9 size classes. How measurements and calculations work →
A measurement difference alone does not establish an installation or support verdict. “Not verified” never means zero.
