You do realize that’s impossible, right? 20 years ago, Windows 95 had been out for a short time. Windows 95 ran on DOS. It wasn’t visible to the user, but it was still there. Windows 95-ME were the last “three” OSs to run on DOS. After that, Microsoft switched over to NT, something focused on getting rid of the cruft…

1/300th of an inch. Retina display is Apple’s term for they’re displays that have pixels smaller than that. Everybody was amazed by it when it first came out, so its an easy tie in.

Because that would suck and have a huge screen-door effect(you could see the gaps between the pixels).

That’s still pretty good. A CPU upgrade costs far less than a GPU upgrade.
