| Description: |
Test code: % winfo screenwidth . 3840 % winfo screenheight . 1080 % winfo screenmmwidth . 1013 # ^ reports total dual monitor width. Monitors are identical, so for each, screenmmwidth = 506.5mm % winfo screenmmheight . 284However, xrandr gives different values which, after measuring the actual screens, prove to be the correct ones: $ xrandr Screen 0: minimum 320 x 200, current 3840 x 1080, maximum 8192 x 8192 VGA-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.0*+ 1680x1050 60.0 1400x1050 60.0 1600x900 60.0 1280x1024 75.0 60.0 1440x900 59.9 1280x800 59.8 1152x864 75.0 1280x720 60.0 1024x768 75.1 60.0 832x624 74.6 800x600 75.0 60.3 56.2 640x480 75.0 60.0 720x400 70.1 HDMI-0 disconnected (normal left inverted right x axis y axis) DVI-0 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.0*+ 1680x1050 59.9 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1Screen geometry reported by xrandr: 3840 x 1080 px (correct). Physical size reported by xrandr: 477mm x 268mm (per screen, correct) Horizontal and vertical screen sizes reported by Tk are wrong. Tests have been done with 2x LG FLATRON E2251 and verified on a single LG-22EA53. The problem is amplified when simulating AndroWish apps on desktop PCs, because it becomes difficult to match font sizes due to the wrong resulting dpi. dzach | |||
