What does "High Resolution" mean exactly?

Hello guys,

I’m wondering what exactly “High Resolution - Yes/No” mean for Wordpress themes?
Does it mean that these themes don’t support “Retina” displays on Apple devices so images will be blurry on high res displays?

Thank you

Currently mean nothing, Envato not update the submission forms by years and problems like this one has never been solved.

if “High Resolution” means nothing, how can you see if a theme supports “Retina” displays?

Maybe is for Retina but there is not any doc I found. Anyway for 99.999% of themes the only support for retina is on the logo image.
