Intel Desktop Scaling
Control the scaling of the LCD screen to stretch the screen to use full LCD. (LVDS1)
Setting scaling mode
This can be useful for some full screen applications.
xrandr --output LVDS1 --set PANEL_FITTING param
where param can be
* center: resolution will be kept exactly as defined, no scaling will be made,
* full: scale the resolution so it uses the entire screen or
* full_aspect: scale the resolution to the maximum possible but keep the aspect ratio.
If it does not work, you can try
xrandr --output LVDS1 --set "scaling mode" param
where param is one of "Full", "Center" or "Full aspect".
alias intel.stretch='xrandr --output LVDS1 --set "scaling mode" Full' alias intel.center='xrandr --output LVDS1 --set "scaling mode" Center'
