HiDPI mode on Windows or Linux

3

OS X has a very nice looking HiDPI mode where the effective screen resolution is only half of the monitor resolution, but with very smooth looking fonts. Is something like that also available for Windows 7 or Ubuntu 12.04?

Windows already has DPI settings for decades. But most programs simply don't respect Windows' DPI value, therefore running a program with scaling larger than 100% in Windows XP or earlier often result in severely broken interface with overlarge or supersmall text, and blurry or pixelated graphics items.

Since Windows Vista, MS has added another scaling style in which all programs are reported to run on a 96-DPI screen and then be scaled uniformly, except when the app explicitly states that it supports custom DPI. That means old apps will have a blurry interface but is still large enough to be usable (no more in Windows 10, see below). But they still defaults to the old XP style scaling until Windows 8.1

XP style scaling

Although Windows 7's high DPI support is not as good as Windows 8/8.1, it's still much better than XP and previous versions. In Windows 8.1 MS has completely removed XP-style scaling options and you can only turn off that for each app individually. Also Windows 8.1 provides a new 200% DPI scaling option which you must manually set in Windows 7, and the result will almost be like OS X's HiDPI mode. It also supports different DPI setting for each display

win8 200% DPI

Windows 10 made further progress by automatically scale text rendering in GDI apps so they don't appear blurry anymore (at least most of their interfaces are now crisp). For more information read


Linux also have partially support for text scaling and/or DPI setting before but it's not very good. Ubuntu 14.04 LTS is the first version that has complete support for tablets and high-DPI screens. However almost all desktop environments just support integer scaling, very few have decent fractional scaling support
