Retina Scaling Options

Does anyone know of a way to get OS X to see ALL displays as being 'retina' such that they can take advantage of the nice scaling options? Like, if I had a 4K display on a Mac, and wanted to be able to slide between 1080p and 4K like the rMBP15 can shift between "1440*900" > "1920*1200".

I'm looking for the OS to do the thing where it's doubling the image and scaling down rather than doing the classic, fuzzy, not-quite-the-right-res thing.
 
The mode is called HiDPI.

Code: 
sudo defaults write /Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled -bool true

Run that command, then log out and back in. Then go into System Prefs, Displays, then hold Option while you click Scaled. I just tried it out on my 1440p display and now I have a bunch of HiDPI modes, which start at 720p an go down from there.

Looks pretty good at these resolutions, much better than the normal scaling. I dont know what it would do on 4K display, but I would expect it to follow a similar pattern.

I'll try that out, thanks
 
What I was specifically talking about was the slider in the settings that true Retina systems have. They don't have a list of resolutions, but rather usually 5 resolutions, 2 on either side (though the rMB may not have that many) of the 'default' res.

Does anyone know of a way of tricking a Mac into thinking that it should do that?
 
Out of curiosity, whats the difference? The buttons just say Normal, Larger Text, More Space, and to the left it says 'looks like <res>'. Option clicking Scaled without doing the defaults command will still show real resolutions.

I suppose it's more that I want what it's doing in the background, which is blowing it up and shrinking it, which yields better looking results than just shrinking it.
