Hi All,

I'm jumping in this thread because I think this 'bug' is the source of many scaling issues.

I'm the owner of a 13" laptop with a 3200x1800 native resolution. As recommended elsewhere, I set the scale factor to 2 and most applications are readable now. However, readable is does not mean correct.

Using 3 different tools, I get 3 different DPI. See below:

>get-edid | parse-edid
Section "Monitor"
 Identifier ""
 ModelName ""
 VendorName "SDC"
 # Monitor Manufactured week 0 of 2014
 # EDID version 1.3
 # Digital Display
 DisplaySize 290 170
 Gamma 2.20
 Option "DPMS" "true"
 Modeline "Mode 0" 361.31 3200 3248 3280 3316 1800 1802 1807 1816 -hsync -vsync
 Modeline "Mode 1" 361.31 3200 3248 3280 3680 1800 1802 1807 2045 -hsync -vsync
EndSection

=> The above info results in about 280 DPI.

>xrdb -query | grep dpi
