I have seen posts tagged with twice or thrice in the past, and each time I replaced it with , whose tag info reads:

High DPI (dots per inch) screen resolutions, e.g. 4k/UHD/QHD screens in a relatively small form factor, e.g. laptops/tablets. Use this tag for issues relating to the Ubuntu experience on HDPI screens.

Largely because of Apple, the term "HiDPI" is also becoming popular (maybe more popular - at any rate, it is easier to read than "HDPI" for me).

I think should be added as a synonym, or made the master and the synonym.

I vote that we make a synonym of , as the latter is easier to read and seems to be the "official" name, at least according to the Arch Wiki and regular Google search results. Note the related queries on Google Trends. From that data itself, we can easily say that "HDPI" refers to mobile displays while "HiDPI" is used for computers. As we aren't Android Enthusiasts, it would only make sense to use as the master tag.

I would, however, express caution turning 4k, UHD, and QHD into synonyms of , as 4k screens are not always HiDPI. Synonymizing (or whatever the tag is) would be a good idea, but this tag doesn't seem to exist yet, making synonymizing it relatively useless.


I would tend to agree due to the recent popularity of the hidpi acronym. I don't think it matters too much which is master and which is synonym, but I would agree having both and having one a synonym of the other would make sense if we are to have either of them.

I can't think of a compelling reason to have either tag to be honest, as I don't see what the screen technology has to do with the OS or why anyone would follow either tag. Perhaps I'm missing something.

  • 4K refers to the number of pixel, not to pixel density. It is not a synonym. :) Commented Apr 12, 2017 at 12:06
