• how set monitor native resolution not listed in resolutions list? 3 answers

dp-1 connected primary 1440x900+1920+0 (normal left inverted right x axis y axis) 160mm x 90mm    1440x900      59.89*+    1920x1080     60.05    60.00    50.04      1280x720      60.00    59.94    50.00      1024x768      60.00      800x600       60.32      720x576       50.00      720x480       59.94      640x480       59.94  

this output xrandr -q

$ lspci | grep vga 01:00.0 vga compatible controller: nvidia corporation device 1c82 (rev a1) 

all of resolutions work (are bad looking though), 1 doesn't work (the 1 want) not. no signal monitor when this:

xrandr --output dp-1 --mode 1440x900

try xrandr --newmode 900p 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync

or

xrandr --addmode 900p 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync

according specifications screen.

supported computer resolutions 1024 x 768 (xga), 1152 x 864, 1360 x 768, 640 x 350, 640 x 480 (vga), 720 x 400, 800 x 600 (svga)

you might find 1360x768 gives better results. (that's resolution use when using tv monitor)
