Abstract
Experiments have been carried out to determine the human eye’s visual acuity, using fragments of pictures containing textures of various scales, and displayed on a cathode ray tube. Care has been taken to ensure that the display properties have not influenced the result.

The results confirm the widely held value of 1 minute of arc, and can be used to determine the TV standards needed in the coming large-screen display age.

It is concluded that the 1280x720 transmission format will suffice for the foreseeable future for domestic requirements in Europe.
