I wonder what the current state of this is? Any distro that supports very high ppi as of today? I have read that mageia offers support, but I wonder if that is truly the case? i find it strange specially because the most relevant DEs apparently don't work well yet?

    This has nothing to do with the distro, if mageia can do it, then so can everyone else. – terdon Feb 3 '14 at 20:08

As Linux uses X11 to do graphical rendering, this question is really about whether X11 supports it.

The answer is yes, X11 supports arbitrary sizes. One example with 4K HD is here.

  • Thanks! I don't understand, though... How is it possible that such massive resolution apparently does not imply more pixels and a higher pixel density? I can clearly see pixels in that image... – user52191 Feb 3 '14 at 19:13
  • Resolution in the computer world correlates directly to pixel count. PPI/DPI/pixel density exists only in the real world. Consider 1080p TVs for example... a 19" 1080p TV has a much higher pixel density than a 60" 1080p TV, but the resolution (and signal on the wire) is still identical. – BowlesCR Feb 3 '14 at 19:18
  • Exactly, that's why, given the fact computer monitors are not that big, pixel density should be amazing in that picture... Probably around 300 ppi for a twenty inches monitor. So yeah, confused that it's not like that at all in that screen. – user52191 Feb 3 '14 at 19:52
  • The image is 3840x2160 - if you "see pixels" you're looking at your own display. The pixel density is only dependent on the physical hardware (on my 27" 2560x1440 screen, I can't see them at a normal viewing distance). – user55325 Feb 3 '14 at 20:03
