Bert64 is correct. X11 has done this for years! X11 has set my dpi to 154 (I think that was the number) on my 8 year old laptop....umm 8 years ago. Windows XP (which was included with the Dell) always hard-coded it it 96 or 120 dpi. Most Windows apps couldn't work in 120 dpi (buttons appear outside a non-resizable window etc), so I was forced to use 96 dpi on a 1920x1200 screen - making for damn small text. Luckily I haven't run Windows on that Dell laptop in years.
Anyway, the hard-coded 96 dpi (from windows) or 72 dpi (from Mac) is what is keeping software and hardware from moving to high dpi displays! Maybe they can actually learn something from X11 and Linux apps (which are much much more high dpi friendly).

Forget Windows 8. Windows 7 doesn't even support manually entering the DPI. You can choose normal, or high. Sometimes you can get it to accept a percentage.

I'd settle for just being able to manually enter the DPI so that I can reduce it on my low-res monitors (like the SD TV). "96 DPI" on a 27" TV with only 480 vertical pixels looks horrible! And "120 DPI" is worse.
Wouldn't it be nice if the OS included methods to query the monitor's physical dimensions, query the video card for the current resolution, and figure out what the *ACTUAL* DPI of the display is? And then use that figure for displaying things so that a resolution change wouldn't change the size of icons, text, images, etc? Or changing monitor sizes wouldn't change text/image/icon sizes?
Oh, wait, those capabilities already exist (EDID, for ex). But none of the OSes out there do this.
