My 11 inch asus laptop has a full hd display. So it's somewhere in the middle. Gnome's hidpi support doesn't allow float values, making this a serious issue to me. On top of that, you'll have to change the cursor size manually by diving into the config. The iphone 6+ display uses downsampling, so perhaps that's the way to go. But as things stand, I don't see my self using an external monitor in the near future, even…

You have a 200dpi screen. Using a scalling factor of 2, you'd still have a higher than average dpi.

For web browsers I thought CTRL+ and CRTL- were for dealing with this, but I think that is stored on a site by site basis. Something similar for the UI would be nice too, but IMHO should be kept independent of the "data" the app displays.

Yup, it brings all kinds of sub-pixel positioning issues as well.

I see that phrasing all the time: "Well, KDE can do what we are looking for, but GNOME does it in a hackish way. As we use GNOME, our review is all about it, and as a conclusion, Linux is no good." Why do these people insist on using GNOME after all?

to take full advantage of that sweet sweet desktop systemd goodness.

Somewhere in the 90's, games were in 320x200 pixel resolution, and the Windows 3.11 desktop was 640x480 pixels or so on a typical 386 computer.

It often is better to sell cheap stuff to many people, than to sell expensive stuff to a few.

VW bought Porsche, Fiat bought Ferrari etc. :D

Please don't post such flamebait. This isn't reddit.

Unfortunately, that's not the case. I have tried it and the usable screen real state is so small, that gnome is unusable. I like big fonts, and found that a scaling of 1.5 is about right.

Your timeline is pretty far off, to my memory. We had VGA graphics games in the early 90s. My Sparcstation 20 came with a 1280x1024 CRT monitor. The 15" Sony CRT I bought shortly after, along with a Matrox Millenium PCI graphics card, was capable of the same. I ran a 21" Sony at 2048x1536 in 1999. It did not flicker.

Very true, although I would add that it is often best to sell moderately expensive stuff to a moderate number of people (i.e., why BMW doesn't sell $10k subcompacts). :)

I have the same display with Debian and no issue. So it's either introduced by Mint or Ubuntu (Mint is Ubuntu derived). Most likely by Mint, as the UI customization is very distro specific.

Must be Mint. Ubuntu's Unity has an adjustable slider for scaling under Display settings. Or more precisely, this is a Desktop Environment thing, not a distro thing. So whatever DE /u/bitL is using in their Mint (Cinnamon?) is the culprit.

Yep, it's Cinnamon, I've just installed a Debian on a new server and switched to Cinnamon, and the same happened there as well... Cinnamon has scaling slider as well, HiDPI is a bit different thing (and a different option in general settings).

I am guessing - is it because of HDMI and its abysmal bandwidth? Before with VGA the actual resolution of CRT monitors was limited by RAMDAC. And 10 years ago I was able to to have 2048x1536@70Hz on a top-end 15" CRT already.

I guess as nowadays all digital signal is routed through content protection filter, the technology processing these streams wasn't performing well, causing stagnation in display resolutions for a long time (well, there was also a limit in DPI of CRTs and immature LCD tech). I guess only nowadays with HDMI 2.0, DisplayPort 1.3 or Thunderbolt we are getting to the point the digital signal can be "properly" controlled by content-protection chips, hence allowing 4K+ resolutions (though it's still a mess).
