Not a mention of any manufacturer, let alone Apple. You straight out
use 'retina display' as a generic term for all high resolution

no. you *assumed* that.

So would anyone else who read what you wrote.

yet another assumption.

nearly all hi-dpi displays are apple retina displays, with more than 1

dell wishes it could have sold a tiny fraction as many.

And Apple has registered "Retina" with the US Trademark off, the
Canadian Intellectual Property Office and in Jamaica. Use the term
'Retina" loosely at your peril.

i didn't use it loosely. i was referring to apple retina displays and
how they work.
