A throw ratio transcribed wrong is worse than a missing one.

Every screen size this site prints is a division done on a number copied off a manufacturer’s page, so one wrong digit propagates to a card, a detail page, a guide and a head-to-head at once. If something here does not match the spec sheet in front of you, that is the most useful message we can get.

What people usually write in about

  • A spec that is wrong — a throw ratio, a lens-shift range, a lag figure, or a lumen number filed under the wrong standard.
  • A projector that should be in the 63 and is not, or one that has been superseded by a model with a new number on the same chassis.
  • A projector that has dropped a class. The figures here are snapshots from 2026-09-23 and a projector that has dropped a thousand dollars is in the wrong class until it is fixed.
  • A recall or a firmware notice we have not seen, which goes on the affected model’s own page rather than into a news post.

What happens after you press send

The message goes to the two people who maintain the catalog — there is no inbox team behind it. Anything claimed here is read back against the manufacturer’s published page and the source URLs already listed on that projector’s detail page. If it holds, the data file changes, every derived figure recomputes from it, and the refresh date at the foot of the page moves. If it does not, you get told why rather than nothing.

We are two people, so a reply can take a few days. What you write is read by both of us and published nowhere; your address exists only to carry the answer back. If you would rather not use the form, chelsea@hagadornwebdev.com reaches the same place.

What we cannot do

Nothing here is measured by us — there is no light meter and no darkened room — so we cannot settle a dispute about what a projector really puts out, only report what is published and say who published it. Manufacturers asking about placement can save the email: no listing, order or write-up on this site is for sale. The full method is in how we compare, and the reasoning behind it in about.

Your address answers you and then goes dark. There is no list, no newsletter, and no projector brand is told who questioned the standard behind its lumen figure.
