I've made a little progress but let me give you some results: xrdb yields dpi = 120 xdpyinfo yields: 3200x1800 pixels (270x216 millimeters) resolution 301x212 dots per inch however: your website yields what seem to me correct values except for dpi. it seems not to capture the dpi values at all but maybe I misinterpret: <https://drive.google.com/file/d/0B--R0Wp8z2MkaTVtNmZ0TnRPNjg/view?usp=sharing> I've commented out HorizSync and VertRefresh though I did run > hwinfo --monitor | grep -A6 'river Inf' and it says "Size: 293x165 mm" so there's some data (or there're some data) and a couple of incongruities. I'll stop here and talk about the progress I alluded to earlier. I think I have kde apps in ok shape by fooling with fonts and setting fonts to System Settings 120 dpi what doesn't work is management of LibreOffice, Firefox, the intro display for Trinity Control Center and various apps which I think are GTK (and then there's that grotesquely large login page). I'll be installing Apache Office which I prefer but suspect it will have the same problem as LO. it seems to me I have to fuss with GTK. or I may follow your advice below and alter the display mode. that's for tomorrow or the next day.
