I think they are hinting at parity with the resolution of the eye. however pixels is kinda misleading unit of resolution as it depends how far away you are from the display, and how wide the display is. for example a 1k square with a field of view of 3 degrees would have a better "resolution" than a 4k square over 75 degrees. You also now have to contend with focus as well,
